Abstract
BACKGROUND Scutellaria barbata D. Don (SB), commonly known as Ban Zhi Lian and firstly documented by Shigong Chen, is a dried whole plant that has been studied for its therapeutic effects on breast cancer, colon cancer, and prostate cancer. Among its various compounds, scutellarin (SCU) has been demonstrated with anti-tumor effects. PURPOSE This study aimed to evaluate the effects of SB water extract (SBW) and scutellarin on breast cancer stem cells (BCSCs), and to investigate their potential therapeutic effects on breast tumors in mice. METHODS BCSCs were enriched from human breast cancer cells (MDA-MB-231 and MDA-MB-361) and their characteristics were analyzed. The effects of varying concentrations of SBW and scutellarin on cell viability, proliferation, self-renewal, and migration abilities were studied, along with the underlying mechanisms. The in vivo anti-tumor effects of scutellarin were further evaluated in SCID/NOD mice. Firstly, mice were inoculated with naïve BCSCs and subjected to treatment with scutellarin or vehicle. Secondly, BCSCs were pre-treated with scutellarin or vehicle prior to inoculation into mice. RESULTS The derived BCSCs expressed CD44, CD133 and ALDH1, but not CD24, indicating that BCSCs have been successfully induced from both MDA-MB-231 and MDA-MB-361 cells. Both SBW and scutellarin reduced the viability, proliferation, sphere and colony formation, and migration of BCSCs. In mice with tumors derived from naïve BCSCs, scutellarin significantly reduced tumor growth, expression of proliferative (Ki67) and stem cell markers (CD44), and lung metastasis. In addition, pre-treatment with scutellarin also slowed tumor growth. Western blot results suggested the involvement of Wnt/β-catenin, NF-κB, and PTEN/Akt/mTOR signaling pathways underlying the inhibitory effects of scutellarin. CONCLUSION Our study demonstrated for the first time that both SB water extract and scutellarin could reduce the proliferation and migration of BCSCs in vitro. Scutellarin was shown to possess novel inhibitory activities in BCSCs progression. These findings suggest that Scutellaria barbata water extract, in particular, scutellarin, may have potential to be further developed as an adjuvant therapy for reducing breast cancer recurrence.

Abstract
Scutellaria Linn., which belongs to the family Lamiaceae, is a commonly used medicinal plant for heat clearing and detoxification. In particular, the roots of S. baicalensis and the entire herb of S. barbata have been widely used in traditional medicine for thousands of years. The main active components of Scutellaria, including: baicalein, wogonin, norwogonin, scutellarein, and their glycosides have potential or existing drug usage. However, the wild resources of Scutellaria plants have been overexploited, and degenerated germplasm resources cannot fulfill the requirements of chemical extraction and clinical usage. Metabolic engineering and green production via microorganisms provide alternative strategies for greater efficiency in the production of natural products. Here, we review the progress of: pharmacological investigations, multi-omics, biosynthetic pathways, and metabolic engineering of various Scutellaria species and their active compounds. In addition, based on multi-omics data, we systematically analyze the phylogenetic relationships of Scutellaria and predict candidate transcription factors related to the regulation of active flavonoids. Finally, we propose the prospects of directed evolution of core enzymes and genome-assisted breeding to alleviate the shortage of plant resources of Scutellaria. This review provides important insights into the sustainable utilization and development of Scutellaria resources.

Abstract
Excess cortisol release is associated with numerous health concerns, including psychiatric issues (i.e., anxiety, insomnia, and depression) and nonpsychiatric issues (i.e., osteoporosis). The aim of this study was to assess the in vitro inhibition of cortisol release, bioaccessibility, and bioavailability exerted by a chemically characterized Scutellaria lateriflora L. extract (SLE). The treatment of H295R cells with SLE at increasing, noncytotoxic, concentrations (5-30 ng/mL) showed significant inhibition of cortisol release ranging from 58 to 91%. The in vitro simulated gastric, duodenal, and gastroduodenal digestions, induced statistically significant reductions (p < 0.0001) in the bioactive polyphenolic compounds that most represented SLE. Bioavailability studies on duodenal digested SLE, using Caco-2 cells grown on transwell inserts and a parallel artificial membrane permeability assay, indicated oroxylin A glucuronide and oroxylin A were the only bioactive compounds able to cross the Caco-2 cell membrane and the artificial lipid membrane, respectively. The results suggest possible applications of SLE as a food supplement ingredient against cortisol-mediated stress response and the use of gastroresistant oral dosage forms to partially prevent the degradation of SLE bioactive compounds. In vivo studies and clinical trials remain necessary to draw a conclusion on the efficacy and tolerability of this plant extract.

Abstract
Scutellaria baicalensis Georgi (SG) and Scutellaria rehderiana Diels (SD) belong to the same genus of Scutellaria in the Labiatae (Lamiaceae) family. SG is confirmed as the medicinal source according to the Chinese Pharmacopeia, but SD is often used as a substitute for SG due to its abundant plant resources. However, the current quality standards are far from sufficient to judge the quality differences between SG and SD. In this study, an integrated strategy of "biosynthetic pathway (specificity) - plant metabolomics (difference) - bioactivity evaluation (effectiveness)" was established to evaluate this quality differences. First, an ultrahigh-performance liquid chromatography-quadrupole time-of-flight mass spectrometry (UHPLC-Q/TOF-MS/MS) method was developed for the identification of chemical components. The abundant components information was obtained and the characteristic constituents were screened according to the location in the biosynthetic pathway as well as species specificity. Then, plant metabolomics combined with multivariate statistical analysis to find differential components between SG and SD. The chemical markers for quality analysis were determined based on the differential and characteristic components, and the content of each marker was tentatively evaluated through the semi-quantitative analysis of UHPLC-Q/TOF-MS/MS. Finally, the anti-inflammatory activity of SG and SD was compared by measuring the inhibitory effect on the release of NO from lipopolysaccharide (LPS)-stimulated RAW 264.7 cells. Under this analytical strategy, a total of 113 compounds were tentatively identified in both SG and SD, among which baicalein, wogonin, chrysin, oroxylin A 7-O-β-D-glucuronoside, pinocembrin and baicalin were selected as chemical markers due to their species characteristics and differentiation. The contents of oroxylin A 7-O-β-D-glucuronoside and baicalin was higher in SG, and the others were higher in SD. In addition, both SG and SD exhibited prominent anti-inflammatory activity, but SD was less effective. The analysis strategy combining phytochemistry and bioactivity evaluation realized the scientific evaluation of the intrinsic quality differences between SG and SD, which provides a reference for fully utilizing and expanding the medicinal resources, and also provides a reference for the comprehensive quality control of herbal medicines.

Abstract
Our previous study confirmed that the combination of Hedyotis diffusa (HD) and Scutellaria barbata (SB) significantly inhibited colorectal cancer cell proliferation and the WNT signaling pathway. However, the exact molecular modulation remains unclear. In this study, colorectal cancer cells (SW620) were treated with 1 mg/mL HD-SB for 24 h, and high-throughput sequencing of circRNAs was performed. The level of hsa_circ_0039933 in three colorectal cancer cell lines (HT-29, SW620, and HCT116) was verified by qPCR. After transfection of hsa_circ_0039933 overexpression plasmids or small interfering RNAs, CCK8, apoptosis, cell migration, and cell invasion were utilized to evaluate the function of hsa_circ_0039933 in the progression of colorectal cancer cells. We identified hsa_circ_0039933, which was downregulated in HD-SB-induced colorectal cancer cells and positively related to colorectal cancer progression. In SW620 cells with relatively high expression of hsa_circ_0039933, interfering with the expression of hsa_circ_0039933 inhibited the proliferation, invasion, and migration of SW620 cells. In HCT116 cells with relatively low expression of hsa_circ_0039933, overexpression of hsa_circ_0039933 promoted the proliferation and invasion and migration ability of HCT116. Mechanistically, hsa_circ_0039933 targeted hsa-miR-204-5p to increase the expression of wnt11, leading to the activation of the Wnt pathway, thereby promoting the proliferation of colorectal cancer cells. This work revealed the potential molecular mechanism of HD-SB for the treatment of colorectal cancer, which was to inhibit the Wnt signaling pathway through the hsa_circ_0039933/hsa-miR-204-5p/wnt11 axis, then suppressing proliferation, migration, and invasion in the colorectal cancer cell.

Abstract
This study aims to examine the impacts of Scutellaria strigillosa Hemsl. (SSH) on the proliferation, apoptosis of human hepatoma cell HepG2 and screen the bioactive components. We found that SSH extract inhibited HepG2 proliferation, arrested cell division prior to S phase. Additionally, SSH extract exposure induced apoptosis, and increased the proportions of late apoptotic cells. Specifically, we focus on the inhibitory effect of SSH extract on aspartate β-hydroxylase, a key therapeutic target of hepatocellular carcinoma closely related with the proliferation and apoptosis of HepG2. We found SSH extract with notable inhibitory activity against aspartate β-hydroxylase, elucidated the main bioactive constituents by HPLC-Q-TOF/MS and Molecular docking analysis. In conclusion, these results provided the antiproliferative and proapoptotic effects of SSH on HepG2 cell, elucidated the main bioactive constituents based on aspartate β-hydroxylase inhibition. These data revealed the potential value of SSH and its bioactive components for the prevention and treatment of liver cancer for the first time.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Neuronal death is a central process in neurodegenerative diseases and represents a therapeutic challenge for their prevention and treatment. Scutellaria incarnata Vent. roots are used traditionally in Colombia for central nervous system conditions including those affecting cognitive functions, but their chemistry and neuroprotective action remain to be explored to understand the scientific basis for their medicinal uses. In this study, S. incarnata roots are investigated to assess whether they have neuroprotective effects that could provide some explanation for their traditional use in neurodegenerative diseases. AIM OF THE STUDY To evaluate the neuroprotective effect of S. incarnata roots and its chemical constituents against C2-ceramide-induced cell death in Cath.-a-differentiated (CAD) cells. MATERIALS AND METHODS S. incarnata root ethanol extract was fractionated and compounds were isolated by column chromatography; their structures were elucidated by nuclear magnetic resonance spectroscopy, mass spectrometry and infrared spectroscopy. The cytotoxic and neuroprotective effects against C2-ceramide of S. incarnata root extract, fractions and isolated compounds were assessed in CAD cells. RESULTS S. incarnata root extract and its n-butanol fraction were not cytotoxic but showed neuroprotective effects against C2-ceramide toxicity in CAD cells. The phenylethanoid glycosides incarnatoside (isolated for the first time) and stachysoside C (12.5, 25 and 50 μg/mL) from S. incarnata roots also protected CAD cells against C2-ceramide without inducing cytotoxic effects. CONCLUSION The observed neuroprotective effects of S. incarnata root extract and isolated phenylethanoid glycosides in CAD cells provide an ethnopharmacological basis for the traditional use of this species in Colombia for central nervous system disorders.

Abstract
Scutellaria scordiifolia Fisch. ex Schrank is used to treat various inflammatory diseases and other ailments in traditional and contemporary medicine. In this study, 10 undescribed compounds, including a flavanone (1), four chrysin C-glycosides (2-5), a phenanthrene glucoside (6), four iridoid glucosides (7-10) and 31 known compounds were identified from an extract of the aerial parts of S. scordiifolia. The absolute configurations of sugars in C-glycosides were determined by comparing electric circular dichroism spectra with calculated data. The flavanones (1 and 17), flavonols (11-13), flavone (14), and some of the flavone glucuronides (15, 16) exhibited trypanocidal activities against Trypanosoma congolense. The activity data and quantitative HPLC analysis of flavonoids from the aerial parts of S. scordiifolia suggest that they may effectively treat diseases caused by the aforementioned trypanosomes. Other compounds such as novel iridoids and phenanthrene glycosides, which may be useful for chemophenetic and chemoecological discussions, were also identified.

Abstract
The presence of anticancer clerodane diterpenoids is a chemotaxonomic marker for the traditional Chinese medicinal plant Scutellaria barbata, although the molecular mechanisms behind clerodane biosynthesis are unknown. Here, we report a high-quality assembly of the 414.98 Mb genome of S. barbata into 13 pseudochromosomes. Using phylogenomic and biochemical data, we mapped the plastidial metabolism of kaurene (gibberellins), abietane, and clerodane diterpenes in three species of the family Lamiaceae (Scutellaria barbata, Scutellaria baicalensis, and Salvia splendens), facilitating the identification of genes involved in the biosynthesis of the clerodanes, kolavenol, and isokolavenol. We show that clerodane biosynthesis evolved through recruitment and neofunctionalization of genes from gibberellin and abietane metabolism. Despite the assumed monophyletic origin of clerodane biosynthesis, which is widespread in species of the Lamiaceae, our data show distinct evolutionary lineages and suggest polyphyletic origins of clerodane biosynthesis in the family Lamiaceae. Our study not only provides significant insights into the evolution of clerodane biosynthetic pathways in the mint family, Lamiaceae, but also will facilitate the production of anticancer clerodanes through future metabolic engineering efforts.

Abstract
Some of the more than 350 Scutellaria species, such as S. baicalensis and S. lateriflora, have been used in traditional medicine and today play an important role in official phytotherapy. Other species have been less investigated, and their therapeutic potential is unknown. This is one of the few studies on Scutellaria brevibracteata subsp. subvelutina, and the first research of this species' in vitro cultures. The aim of this study was to establish an in vitro culture and analyse its phytochemical profile and biological activity. In the methanolic extracts from biomass cultured on six solid Murashige and Skoog (MS) medium variants supplemented with different combinations of 6-benzylaminopurine (BAP) and 1-naphthaleneacetic acid (NAA) in the range 0.5-3 mg/L analysed by HPLC, the presence of specific flavonoids (baicalein, baicalin, wogonin, wogonoside, scutellarin, chrysin), phenylpropanoid glycosides (verbascoside, isoverbascoside), and phenolic acids (p-hydroxybenzoic, caffeic, ferulic, m-coumaric acids) was confirmed. The dominant metabolites were wogonoside and verbascoside with the highest content of 346 and 457 mg/100 g DW, respectively. Thus, the extract with the highest content of bioactive metabolites was selected for further research and subjected to evaluation of antioxidant and antimicrobial potential. The extract exhibited good free radical scavenging activity (IC50 = 0.92 ± 0.01 mg/mL) and moderate reducing power and chelating activity. The brine shrimp lethality bioassay proved its lack of biotoxicity. Antimicrobial activity was tested against sixteen strains of Gram-positive and Gram-negative bacteria and fungi. The strongest growth inhibitory activity was observed against Trichophyton tonsurans.

Abstract
Diterpenoids are considered the major bioactive components in Scutellaria barbata to treat cancer and inflammation, but few comprehensive profiling studies of diterpenoids have been reported. Herein, a stepwise diagnostic product ions (DPIs) filtering strategy for efficient and targeted profiling of diterpenoids in Scutellaria barbata was developed using UHPLC-Q-Exactive-Orbitrap-MS. After UHPLC-HRMS/MS analysis of six diterpenoid reference standards, fragmentation behaviors of these references were studied to provide DPIs. Then, stepwise DPIs filtering aimed to reduce the potential interferences of matrix ions and achieve more chromatographic peaks was conducted to rapidly screen the diterpenoids. The results demonstrated that stepwise DPIs were capable of simplifying the workload in data post-processing and the effective acquisition of low abundance compounds. Subsequently, DPIs and MS/MS fragment patterns were adopted to identify the targeted diterpenoids. As a result, 381 diterpenoids were unambiguously or tentatively identified, while 141 of them with completely new molecular weights were potential new diterpenoids for Scutellaria barbata. These results demonstrate that the developed stepwise DPIs filtering method could be employed as an efficient, reliable, and valuable strategy to screen and identify the diterpenoid profile in Scutellaria barbata. This might accelerate and simplify target constituent profiling from traditional Chinese medicine (TCM) extracts.

Abstract
Scutellaria genus, a member of the Lamiaceae family, distributed worldwide and known as skullcaps, contains a wide range of pharmacologically active constituents including flavonoids and diterpenes. There are different classes of diterpenes in the plant kingdom, of which many have medicinal applications. Scutellaria spp. contain neo-clerodane diterpenes, a large group of naturally occurring specialized metabolites found in both plant species and in organisms from other taxonomic groups, such as fungi, bacteria, and marine sponges. Although many phytochemical studies have been established reporting interesting specialized diterpene structures from Scutellaria spp., there has not been a comprehensive study reviewing these compounds. Hence, the present review reports on natural diterpenoids from the Scutellaria genus and their pharmacological activities. For this purpose, the scientific databases including Scopus, PubMed, and Google Scholar were searched using the keywords "Scutellaria" and "Diterpenes" or "Diterpenoids". The literature review showed that up to now, more than 300 diterpenes have been isolated and reported from the Scutellaria genus, belonging to neo-clerodane scaffolds. Anticancer, antifeedant, phytotoxic, antimicrobial, and nitric oxide production inhibitory activities are the most reported properties for the diterpenoids from the Scutellaria genus. Diterpenes of Scutellaria spp. have therapeutic potentials to be used for the treatment of different diseases. Further phytochemical, pharmacological, and clinical studies are required in this regard.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Radix scutellariae (the root of Scutellaria baicalensis Georgi), is a traditional Chinese medicine (TCM) used to treat type 2 diabetes mellitus (T2DM). Abundant flavonoids are the antidiabetic components of Radix scutellariae, of which baicalin (Baicalein 7-O-glucuronide, BG) is the major bioactive component. Our previous studies found that the water extract of Radix scutellariae (WESB) could exert hypoglycemic and hypolipidemic efficacies by adjusting the ileum FXR-medicated interaction between gut microbiota and bile acid (BA) metabolism. However, it remains unclear whether WESB and its biologically active ingredients exert an antidiabetic effect through bile acid signaling mediated by FXR-CYP7A1. AIMS OF THE STUDY To explore the mechanism of WESB and its total flavonoids (TF) further and BG on BA signals and glycolipid metabolism in T2DM mice. MATERIALS AND METHODS The antidiabetic effects of WESB, TF and BG were evaluated by indexing the body weight, fasting blood glucose (FBG) and oral glucose tolerance test (OGTT) in HFD/STZ-induced (high-fat diet and streptozocin) diabetic mice, and comparing them with the positive control (metformin). The lipids in the mouse liver and the total bile acids (TBA) in the mouse liver and bile were detected by commercial kits. The concentration of BAs in the mouse feces was determined by liquid chromatography-tandem mass spectrometry. The protein expression levels of cholesterol 7α-hydroxylase (CYP7A1), farnesol X receptor (FXR), etc., in the liver and/or ileum, play a key role in the BAs metabolism of T2DM mice were evaluated by immunoblot analysis. RESULTS The hyperglycemia and impaired glucose tolerance of T2DM mice were improved after WESB, TF and BG treatment. Especially after BG administration, the levels of low-density lipoprotein-cholesterol (LDL-c) and total glyceride (TG) in the T2DM mouse liver were significantly decreased (p < 0.05). While the level of high-density lipoprotein cholesterol (HDL-c) was significant increased (p < 0.001). Meanwhile, the levels of TBA in both the liver and bile of T2DM mice were significantly decreased by BG (p < 0.05). Moreover, the high expression of CYP7A1 in the liver of T2DM mice was significantly inhibited by WESB, TF and BG (p < 0.05), and the high expression of FXR in the ileum of T2DM mice was significantly inhibited by TF (p < 0.05). CONCLUSION These results indicated that the hypoglycemic effects of WESB, TF and BG might be exerted by inhibiting the expression of CYP7A1 in T2DM mice, and TF inhibited expression of intestinal FXR by inducing changes in fecal BA profile. BG significantly improved hepatic lipid metabolism. Moreover, BG reduced lipid accumulation in the liver and bile by inhibiting the expression of CYP7A1 in T2DM mice. These findings provide useful explanations for the antidiabetic mechanism of Radix scutellariae.

Abstract
Scutellaria (Lamiaceae) comprises over 360 species. Based on its morphological structure of calyx, also known as Skullcap, it is herbaceous by habit and cosmopolitan by habitat. The species of Scutellaria are widely used in local communities as a natural remedy. The genus contributed over three hundred bioactive compounds mainly represented by flavonoids and phenols, chemical ingredients which serve as potential candidates for the therapy of various biological activities. Thus, the current review is an attempt to highlight the biological significance and its correlation to various isolated bioactive ingredients including flavonoids, terpenoids, phenols, alkaloids, and steroids. However, flavonoids were the dominant group observed. The findings of the Scutellaria reveal that due to its affluent basis of numerous chemical ingredients it has a diverse range of pharmacological potentials, such as antimicrobial, antioxidant, antifeedant, enzyme inhibition, anti-inflammatory, and analgesic significance. Currently, various bioactive ingredients have been investigated for various biological activities from the genus Scutellaria in vitro and in vivo. Furthermore, these data help us to highlight its biomedical application and to isolate the responsible compounds to produce innovative medications as an alternative to synthetic drugs.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Hedyotis diffusa Willd and Scutellaria barbata D.Don (HD-SB) pairing were widely used as traditional medicine known for their anti-tumor effects. However, the inhibitory effect of HD-SB on ovarian cancer and its potential mechanisms were still not clear. AIM OF THE STUDY Our study identified the anti-tumor effect of HD-SB on ovarian cancer and analyzed the potential mechanisms by the network pharmacology and molecular docking method. MATERIALS AND METHODS The inhibitory effect of HD-SB combination on the growth and migration of ovarian cancer was detected by MTT and transwell assays. The effective ingredients of HD-SB and their potential targets were obtained from the Traditional Chinese Medicines for Systems Pharmacology Database (TCMSP), the GeneCards database, and the UniProt database. The relationships between active ingredients of HD-SB and potential targets or pathways of ovarian cancer were analyzed by String database, Cytoscape 3.7.2 software, and David 6.7 online database. The anti-ovarian cancer targets of HD-SB in the focal adhesion pathway were identified by RT-qPCR and molecular docking. RESULTS HD-SB combination significantly inhibited the proliferation and migration of ovarian cancer cells. We observed that the 1:2 ratio of HD-SB had the lowest IC50 value. 60 gene targets of 33 active ingredients in HD-SB were selected by pharmacokinetic parameters. The network pharmacological analysis showed that quercetin, luteolin, and baicalein might be the important anti-ovarian cancer ingredients in HD-SB, and the inhibitory effects of these three ingredients on the proliferation of ovarian cancer cells were verified respectively. Functional enrichment results suggested that HD-SB inhibited ovarian cancer growth and migration mainly through the focal adhesion pathway and the potential targets were EGFR, MAPK1, VEGFA, and PIK3CG. CONCLUSIONS HD-SB pairing significantly inhibited the proliferation and migration of ovarian cancer. Using network pharmacological methods and validation experiments, we found that HD-SB might, at least partially, inhibit ovarian cancer through the focal adhesion pathway. We believed that the HD-SB combination could be a potential therapeutic drug for the treatment of ovarian cancer patients.

Abstract
We report the development of in vitro propagation protocols through an adventitious shoot induction pathway for a rare and medicinal Scutellaria havanensis. In vitro propagation studies using nodal explants showed MS medium supplemented with 10 µM 6-Benzylaminopurine induced the highest number of adventitious shoots in a time-dependent manner. A ten-day incubation was optimum for shoot bud induction as longer exposures resulted in hyperhydricity of the explants and shoots induced. We also report preliminary evidence of Agrobacterium tumefaciens EHA105-mediated gene transfer transiently expressing the green fluorescent protein in this species. Transformation studies exhibited amenability of various explant tissues, internode being the most receptive. As the plant has medicinal value, research was carried out to evaluate its potential antioxidant capacity and the efficacy of methanolic leaf extracts in curbing the viability of human colorectal cancer cell line HCT116. Comparative total polyphenol and flavonoid content measurement of fresh and air-dried leaf extract revealed that the fresh leaf extracts contain higher total polyphenol and flavonoid content. The HCT 116 cell viability was assessed by colorimetric assay using a 3-(4,5-dimethyl-thiazol-2-yl)-2,5-diphenyltetrazolium bromide, showed a steady growth inhibition after 24 h of incubation. Scanning electron microscopy of leaf surface revealed a high density of glandular and non-glandular trichomes. This research provides a basis for the conservation of this rare plant and future phytochemical screening and clinical research.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Scutellaria barbata D.Don (SB) and Oldenlandia diffusa (Willd.) Roxb are commonly known as Ban Zhi Lian and Bai Hua She Cao in Chinese herbal medicines, respectively. As a pair of herbs, they have traditionally been used as ethnomedicines for clearing away heat and toxins, removing blood stasis, and promoting blood circulation, diuresis, and detumescence. AIM OF THE STUDY The aim of the present study was to determine the active ingredients in SB and OD extracts and to investigate whether these extracts can inhibit the growth of hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC) cell lines (HepG2.2.15 and Hep3B) in vitro and in vivo, as well as to explore their mechanisms of action. MATERIALS AND METHODS We determined the levels of total flavonoids, luteolin, and apigenin in SB and OD extracts via ultraviolet-visible spectrophotometry and high-performance liquid chromatography. The effects of SB and OD extracts on HBV-associated HCC cell growth were assessed by HepG2.2.15 and Hep3B cells phenotype and RNA sequencing of Hep3B cells in vitro, and xenograft models in vivo. RESULTS The extracts of SB and OD contained total flavonoids. There were active ingredients of luteolin and apigenin in SB, but not in OD. The extracts of SB and OD significantly inhibited HCC growth, migration, invasion, and HBV activity in vitro and in vivo, as well as altered circRNA expression in Hep3B cells. Moreover, we constructed a circRNA-miRNA-mRNA co-expression network. CONCLUSIONS The extracts of SB and OD may inhibit HCC cell growth and HBV activity in vitro and in vivo through altering circRNA-miRNA-gene expression and that the efficacies of these extracts may be related to the presence of luteolin and apigenin.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Scutellaria (Lamiaceae), which includes approximately 360-469 accepted species, is widespread in Europe, North America, East Asia, and South America. Several species have a long history being used as traditional medicines to treat respiratory, peptic, neurological, and hepatic and gall diseases. The phytochemistry and pharmacology of the genus Scutellaria have been developed dramatically in the past ten years, and the traditional uses and clinical studies of the genus have not been systematically summarized. Therefore, it is especially valuable to review the current state of knowledge to provide a basis for further exploration of its medicinal potential. AIM OF THE REVIEW The review aims to provide updated information on the ethnopharmacology, the ten-year research progress of phytochemistry and pharmacology, and clinical studies of Scutellaria and to explore the potential medicinal values and further studies of Scutellaria. MATERIALS AND METHODS This review is based on published studies and books from the library and electronic sources, including SciFinder, Scopus, PubMed, Web of Science, Baidu Scholar, CNKI, the online ethnobotanical database, and ethnobotanical monographs. This literature is related to ethnopharmacology, the ten-year research progress on the phytochemistry and pharmacology, and clinical studies of Scutellaria. RESULTS A total of 50 species, 5 subspecies and 17 varieties of the genus Scutellaria are used as traditional medicine with various biological activities. In the past ten years, 208 chemical constituents have been identified from 16 species and 1 variety of the genus Scutellaria, such as neo-clerodane diterpenoids, sesterterpenoids, terpenoids, flavonoids. Pharmacological research has demonstrated that the extracts and compounds identified from this genus exhibit extensive biological activities, including anticancer, antioxidant, anti-inflammatory, antiviral and antibacterial activities, effects on cardiovascular, cerebrovascular diseases as well as hepatoprotective and neuroprotective effects. The species S. baicalensis, S. barbata, and S. lateriflora and the main compounds baicalein, baicalin and wogonin are involved in clinical trials, which point the way for us to conduct further studies, such as study on the anticancer, antihypertensive, anti-infective, anti-inflammatory, neuroprotective and other effects of Scutellaria. CONCLUSIONS The species included in the genus Scutellaria can be used to treat cancer, infection, hepatic disorders, cardiovascular and cerebrovascular diseases, neurodegenerative diseases, and other diseases. Some indications in traditional medicines have been confirmed by modern pharmacological studies, such as anticancer, anti-inflammatory, anti-infective activity, and hepatoprotective and neuroprotective effects. The available literature indicated that most of the bioactivities could be attributed to flavonoids and neo-clerodane diterpenoids. Although there are some uses of Scutellaria in clinical practice, the existing research on this genus is still limited. In order to expand the development of medicinal resources of Scutellaria, the already studied species in this genus are recommended for more comprehensive investigation on their active substances, pharmacological mechanisms, quality control, clinical use and new drug research. Additionally, it is necessary to study species that their chemical composition or pharmacological activity have not yet been investigated, especially those used in folk medicine.

Abstract
Within an Open Science project, research was carried out to describe to the public of the Ghirardi Botanic Garden (BS, Lombardy, Italy) the invisible features of plants. This work is dedicated to Scutellaria altissima L. (Lamiaceae). Micromorphological, histochemical and phytochemical investigations were conducted on the vegetative and reproductive organs to correlate the structures involved in the emission of substances and their unique productivity. This work reports volatile organic compound (VOC) profiles of leaves and flowers and the composition of essential oil (EO) obtained from aerial parts of plants cultivated in Italy that have never been described before. Three morphotypes of glandular trichomes were observed: peltate, short-stalked capitate and long-stalked capitate. Peltate trichomes were the main producers of terpenes, short-stalked capitates of polysaccharides and long-stalked capitates of terpenes and polyphenols. The leaf VOC profile showed heterogeneous composition, with non-terpene derivatives as the major chemical class (71.04%), while monoterpene hydrocarbons represented almost the totality of the flower (99.73%). The leaf presented a higher number of total (37 versus 11) and exclusive (33 versus 7) compounds. (Z)-3-Hexenol acetate was most abundant in the leaf and (E)-β-ocimene in the flower. Four common compounds were detected: β-pinene, β-caryophyllene, γ-muurolene and germacrene-D. The EO contaied 21 compounds, dominated by β-caryophyllene, linalool and hexahydrofarnesyl acetone. This research allowed us to correlate morphotypes of the secretory structures with the production of secondary metabolites, with the aim of providing the public of the Ghirardi Botanic Garden with a dedicated iconographic approach, which accounts for olfactory perception linked to S. altissima.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The Scutellaria barbata and Hedyotis diffusa (SH) herb pair is extensively used in Traditional Chinese Medicine for efficacy enhancement in cancer treatment in China and Asian countries. Superior clinical efficacy observations based on high dosages (≥60 g) motivated us to explore appropriate dosages and the underlying mechanisms of action. AIM OF THE STUDY To explore the efficacy and potential mechanisms of actions of SH through in vitro and in vivo experiments and network pharmacology. MATERIALS AND METHODS SH lyophilized powder (SHLP) was prepared from decoctions and the active ingredients were identified using high performance liquid chromatography (HPLC). Proliferation and migration experiments in vitro and tumor growth in vivo were performed to evaluate the effects of SHLP on breast cancer. Corresponding potential target genes for SHLP components and breast cancer were extracted from established databases and the Protein-Protein Internetwork of shared genes were constructed using STRING database. Kyoto Encyclopedia of Genes and Genomes (KEGG) functional annotation clusters were acquired and the top 30 pathways were presented. At last, as one of pathways indicated by enriched results, apoptosis was validated with flow cytometric analysis and caspase-3, 8, 9 activities. RESULTS Seventy-five ingredients were identified from SHLP by HPLC. High SHLP doses inhibited proliferation and migration of three types of breast cancer cells in vitro and tumor growth in nude mice. After target genes extraction and intersection, the top 30 KEGG clusters were enriched, including PI3K-Akt, cell cycle and other related pathways like VEGF, Micro-RNAs and NF-κB, besides, key genes in apoptosis were mapped. In the last, apoptosis was validated by flow cytometric analysis and caspase-3, 8, 9 activities after SHLP treatment. CONCLUSION High SHLP dosages inhibited breast cancer in vitro and in vivo, enriched by network pharmacology and confirmed by flow cytometric analysis and caspase activation, with apoptosis was identified as one of the mechanisms of action of SHLP. SHLP administration with higher doses is recommended for clinical usage.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Scutellaria barbata D. Don (S. barbata) is a well-known perennial herb that is used in traditional Chinese and Korean medicine. In China, it is known as Ban Zhi Lian, while in Korea, it is known as Banjiryun. In the Traditional Chinese Medicine (TCM) system, S. barbata has heat-clearing and detoxifying properties (Qingre Jiedu in Chinese). AIM OF THE REVIEW To provide a systematic review on current multifaceted understanding of S. barbata, with particular emphasis on the correlation between its traditional applications and pharmacological activities. MATERIALS AND METHODS All available S. barbata-related information from internet databases, including PubMed, Science Direct, Elsevier, China National Knowledge Internet, and Google Scholar (up to October 2018) were searched. Additional information was gathered from classical books on Chinese Herbals, Chinese Pharmacopoeia, and so on. RESULTS In the TCM system, S. barbata is mainly prescribed for its heat-clearing and detoxifying effects. More than 203 compounds have been isolated and identified from this herb, with neo-clerodane diterpenoids and flavonoids as the main compounds. Most neo-clerodanes have been demonstrated to have cytotoxic effects against different cancer cell types in vitro. The S. barbata extracts exhibited anti-inflammatory, anti-microbial, antitumor, and other pharmacological activities. To add, flavonoids, including wogonin, baicalein, apigenin, naringenin, and scutellarin, were identified as the key to quality control. CONCLUSIONS The heat-clearing effects of S. barbata could be attributed to its anti-inflammatory and hepatoprotective activities, whereas its detoxifying effects might be due to the anti-microbial functions of neo-clerodane diterpenoids and flavones. S. barbata may display anti-tumor effects and through active ingredient analysis, neo-clerodane diterpenoids are suggested to be its representative compounds. Overall, many pre-clinical studies have been conducted but very little concrete evidences are available on its specific effects, which are of therapeutic relevance.

Abstract
Bioactivity guided the isolation of extracts from the aerial parts Scutellaria barbata D. Don to discover neo-clerodane diterpenoids with potent phytotoxic activity. Of the 34 isolates, 13 neo-clerodane diterpenoids were described for the first time. The structures of these undescribed compounds were elucidated by extensive analysis of NMR spectroscopic data, and the absolute configurations of scutebarbolides A and L and scutebata W were determined by X-ray diffraction. The phytotoxic activity of all compounds against the growth of the roots and shoots of L. perenne and L. sativa seedlings were first reported, and some compounds showed considerable inhibitory effects, especially scutebarbolide K, whose inhibition rates were higher than those of the positive control at concentrations ranging from 25 to 200 μg/mL. When L. perenne and L. sativa seedlings were treated at a concentration of 200 μg/mL, scutebarbolide K caused wilting symptoms on and finally death of these two tested plant seedlings. In addition, the structure-activity relationships of these neo-clerodane diterpenoids were also discussed.

Abstract
BACKGROUND Though several neuroprotective agents have been evaluated as potential treatments for acute ischemic stroke, none have demonstrated a definitive treatment efficacy, which remains elusive. HT047 is an herbal extract of Scutellaria baicalensis and Pueraria lobata, both of which have been widely used to treat ischemic stroke in traditional Korean medicine. The aims of this trial are to investigate whether HT047 can improve neurologic status, particularly motor function, in acute ischemic stroke patients, and to determine the safety of HT047. METHODS A multicenter, double-blind, randomized, placebo-controlled, 3-arm parallel group, phase II trial will be conducted in patients who have had an acute ischemic stroke within the past 14 days. The participating patients must have a Fugl-Meyer assessment (FMA) motor score ≤55, with arm or leg weakness, and Korean version of the National Institutes of Health Stroke scale (K-NIHSS) score of ≥4 and ≤15. Seventy-eight participants will be randomized in a 1:1:1 ratio and given high-dose HT047 (750 mg 3 times a day), low-dose HT047 (500 mg 3 times a day), or a placebo for 12 weeks. The primary endpoint is the change in FMA motor score between baseline and week 12. Secondary endpoints are as follows: the change in FMA motor score at weeks 4 and 8 from baseline; the change in FMA motor score at weeks 4, 8, and 12 from baseline according to the timing of treatment initiation (either within 1 week, or 1-2 weeks), or according to the presence of prognostic risk factors (hypertension, diabetes, dyslipidemia, etc); the change in K-NIHSS and Korean versions of the modified Rankin scale (K-mRS) and the modified Barthel index at weeks 4 and 12 from baseline; and the proportion of subjects at week 12 with a K-NIHSS score of 0 to 2, or with K-mRS scores of 0, ≤1, and ≤2. DISCUSSION This study is a 1st-in-human trial of HT047 to explore the efficacy and safety in acute ischemic stroke patients. The results will provide the appropriate dosage and evidence of therapeutic benefit of HT047 for stroke recovery. TRIAL REGISTRATION ClinicalTrials.gov (NCT02828540) Registered July 11, 2016.

Abstract
BACKGROUND Non-alcoholic fatty liver disease (NAFLD) has become a major cause of chronic liver disease. The Chinese herbal medicine (CHM) Dachaihu decoction (DCHD) has been proved to treat NAFLD with good efficacy in previous studies. Based on the TCM principle of formula formation, we divided DCHD into soothing liver part, invigorating spleen part, and dredging intestine part. Marshall officially proposed the concept of “intestinal-hepatic axis”, which systematically explains the interactions between the intestine and liver. We hypothesized that the effect of CHM on NAFLD is achieved by regulating the liver and intestine. Thus, we aimed to investigate the possible effect of a CHM formula on NAFLD in a rat model.
AIM To investigate the effects of a CHM formula (a decoction of Chinese thorowax root, scutellaria root, and white peony root) on NAFLD and its regulatory effect on the “intestinal-liver” axis.
METHODS Sixty rats were randomly divided into control, model, pioglitazone hydrochloride (PH), and CHM (a decoction of Chinese thorowax root, scutellaria root, and white peony root) groups. An NAFLD rat model was established using a high-fat high-fructose diet for 16 wk. From the 13th week, rats were administered with PH or a decoction of Chinese thorowax, scutellaria, and white peony root (CHM group) for 4 wk. Rats in the control group and model group were administered with an equal volume of distilled water. At the end of the study, blood was collected via the abdominal aorta. Liver tissues were harvested and any morphological changes were observed by hematoxylin-eosin (HE) staining, Oil red O staining, and Masson staining. In addition, blood lipids, liver function markers, and triglyceride (TG) in liver tissues were analyzed. The levels of transforming growth factor-β1 (TGF-β1), tumor necrosis factor-α (TNF-α), Toll-like receptor-4 (TLR4), and nuclear factor-kappa B (NF-кB) in liver tissues and secreted immunoglobulin A (sIgA) in intestinal tissues were analyzed by ELISA, and protein and mRNA expression of occludin and zonula occludens-1 (ZO-1) in the intestine were measured using Western blot and reverse transcription-quantitative polymerase chain reaction, respectively. The endotoxin level in plasma was detected by endpoint chromogenic assay.
RESULTS Compared to the normal control group, the liver coefficient, serum TG, total cholesterol (TC), low density lipoprotein (LDL), aspartate aminotransferase (AST), and alanine aminotransferase (ALT), blood glucose, plasma endotoxin, and the levels of TG, TNF-α, TGF-β, NF-kB, and TLR4 in liver tissues increased significantly in the model group, while serum high density lipoprotein (HDL), intestinal sIgA, and protein and mRNA expression of occludin and ZO-1 decreased significantly in the model group (P < 0.01). PH and CHM attenuated the elevated liver coefficient, serum TG, TC, LDL, AST, and ALT, blood glucose, plasma endotoxin, and the levels of TG, TNF-α, TGF-β, NF-kB, and TLR4 in liver tissues and increased serum HDL levels compared to the model group (P < 0.01). Intestinal sIgA and the protein and mRNA expression of intestinal occludin and ZO-1 were significantly increased in the PH group compared to the model and CHM groups (P < 0.01).
CONCLUSION The decoction of Chinese thorowax root, scutellaria root, and white peony root is beneficial in regulating lipid metabolism and liver function, which indicates that it has a good effect on the liver. To a certain extent, this CHM formula can affect both the liver and intestine, while its effect on the liver is superior to that on the intestine.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The abnormal increase in vascular smooth muscle cell (VSMC) proliferation and migration are critical events in the pathogenesis of cardiovascular diseases (CVDs) including restenosis and atherosclerosis. The dried roots of Scutellaria baicalensis Georgi (common name: Huangqin in China) have been confirmed to possess beneficial effects on CVD by clinical and modern pharmacological studies. Flavonoids in Huangqin exert anti-proliferative and anti-migratory effects. Similar to Huangqin, Scutellaria strigillosa Hemsley (SSH) has been used to clear heat and damp and is especially rich in flavonoids including wogonin, wogonoside, baicalein, and baicalin. However, there have been few of reports about pharmacological activities of SSH. AIM OF THE STUDY To investigate the anti-proliferative and anti-migratory properties of Scutellaria strigillosa Hemsley extract (SSHE) in vitro and in vivo and explore its possible mechanism of action. MATERIALS AND METHODS The chemical constituents of SSHE were analyzed by ultra-high performance liquid chromatography coupled with triple time-of-flight mass spectrometry (UPLC-Triple-TOF-MS/MS). Cell proliferation and migration were investigated using BrdU incorporation assay and cell scratch test, respectively. The protein expression was determined by western blotting. In vivo, we established an artery ligation model of C57BL/6 mice and orally administered them with 50 or 100 mg/kg/day of SSHE. The carotid arteries were harvested and the intima-media thickness was examined 28 days post-ligation. RESULTS Twelve compounds were identified and tentatively characterized. SSHE significantly inhibited the VSMC proliferation and migration stimulated by PDGF-BB and decreased the relative protein expression of regulatory signaling intermediates. Furthermore, the expression of SM22α was significantly elevated in SSHE-pretreated VSMCs, whereas knockdown of SM22α impaired the PDGF-BB-induced proliferation and migration arrest. Meanwhile, both ROS generation and the phosphorylation of ERK decreased in SSHE-pretreated VSMCs. In carotid artery ligation mice model, SSHE treatment significantly inhibited neointimal hyperplasia. CONCLUSIONS SSHE significantly inhibited the PDGF-BB-induced VSMC proliferation, migration, and neointimal hyperplasia of carotid artery caused by ligation. Upregulation of SM22α expression, inhibition of ROS generation and ERK phosphorylation were, at least, partly responsible for the effects of SSHE on VSMCs.

Abstract
OBJECTIVE To determine the efficacy of Scutellaria barbata flavonoids and polysaccharides on Ishikawa endometrial carcinoma cells co-cultured with U937 macrophages. METHODS The presence of CD163 and CD206 was determined by flow cytometry. Thiazolyl Blue Tetrazolium Bromide assays were used to assess the proliferation effect of tumor-associated macrophages (TAMs) on Ishikawa cells. The secretion of interleukin (IL)-10 in the co-culture conditioned media was examined using an enzyme-linked immunosorbent assay. The protein expression levels of Toll-like receptor 4 (TLR4), myeloid differentiation factor 88 (MyD88) and nuclear factor (NF)-κB p65 were detected by Western blot. The mRNA expression levels of TLR4 and MyD88 were analyzed by real-time polymerase chain reaction (PCR). The expression levels of IL-12, IL-1β and tumor necrosis factor-α (TNF-α) were evaluated with real-time PCR. RESULTS Compared with the U937 control group, the expression levels of CD163 and CD206 in the TAM group were higher (P < 0.05). TAMs co-cultured with Ishikawa cells for 24 or 48 h showed higher proliferation rates (P < 0.05). The expression levels of IL-12 decreased than compared with those in the U937 untreated group (P < 0.05) and those of the Scutellaria barbata flavonoids group (P < 0.05). The expression levels of CD206, CD163, IL-10, IL-1β and TNF-α, NF-κB p65 and TLR4/MyD88 in the TAMs control group were greater than those in the U937 untreated group (P < 0.05) and those of the Scutellaria barbata flavonoids group (P < 0.05). CONCLUSION Scutellaria barbata flavonoids may inhibit TAM activation by blocking the TLR4/MyD88/NF-κB signaling pathway.

Abstract
BACKGROUND It is widely known that reactive oxygen species (ROS) can cause oxidative damage in cells and have been linked to the pathogenesis of oxidative diseases, such as atherosclerosis, ischemia, neurodegenerative disease, diabetes, or cancer. Recently, much attention has been focused on preventive strategies for oxidative stress and related diseases. Plants represent a source of bioactive compounds whose antioxidant activity may be useful in protecting against pro-oxidative reactions. OBJECTIVES The study determines the in vitro biological activity of the ethanolic extracts from the shoots and roots of Scutellaria species (S. altissima and S. alpina) in selected blood cells (blood platelets and lymphocytes). MATERIAL AND METHODS Platelet activity, both resting and after thrombin stimulation, was used to indicate the ability of the plant extracts to inhibit the production of superoxide anion radicals (O2 •-) and platelet lipid peroxidation. The generation of superoxide anion radicals was measured by cytochrome c reduction. Lipid peroxidation in blood platelets was measured by the level of thiobarbituric acid reactive substances (TBARS). The 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) colorimetric assay was used to determine the protective effect of Scutellaria extracts on lymphocyte cells against oxidative damage induced by hydroxyl radicals. RESULTS Extracts (5-50 μg/mL) containing phenolic compounds from both Scutellaria species distinctly reduced nonenzymatic lipid peroxidation and arachidonic acid metabolism by blood platelets in vitro. When given at the tested concentration, the extracts reduced the generation of O2 •- in resting blood platelets and platelets activated by thrombin in vitro. All Scutellaria extracts (10 μg/mL) containing phenolic compounds also protected human lymphocytes against oxidative stress induced by hydrogen peroxide (H2O2). CONCLUSIONS The present study suggests that the natural extracts from S. altissima and S. alpina have antioxidant properties and, therefore, may be beneficial in the prevention of diseases in which blood platelets and lymphocytes are involved, i.e., cancer or inflammatory and infective diseases.

Abstract
Listeria monocytogenes (LM) is a classical model intracellular pathogen and the leading cause of listeriosis, which has long been a global public health issue. The successful infection of LM is related to a series of virulence factors, such as the transpeptidase enzyme sortase A (SrtA) and listeriolysin O (LLO), which are crucial for bacterial internalization and escape from phagosomes respectively. It is speculated that targeting multiple virulence factors may be due to a synergistic effect on listeriosis therapy. In this study, an active flavonoids component of Scutellaria baicalensis Georgi, baicalein, was found to potently block both listerial SrtA catalyzed activity and LLO hemolytic activity within 16 μg/mL. After pretreatment with baicalein, 86.30 (±11.35) % of LM failed to associate with Caco-2 cells compared to the LM without preincubation (regarded as 100% internalization). Furthermore, baicalein addition may aid in bacterial degradation and clearance in macrophagocytes. During a 5 h observation, LM in cells incubated with baicalein showed significantly decreased vacuole escapes and sluggish endocellular growth. In addition, baicalein directly prevented LM-induced cells injury and mice fatality (survival rate from 10.00% to 54.55% in 4 days post-intraperitoneal injection). Taken together, as an antagonist against SrtA and LLO, baicalein can be further developed into a biotherapeutic agent for listeriosis.

Abstract
BACKGROUND The worsening problems of antibiotic resistance prompt the need for alternative strategies. Baicalin, which is isolated from Scutellaria baicalensisi, has been demonstrated to exhibit anti-inflammatory, anti-virulence and antimicrobial effects. Salmonella typhimurium is an important foodborne pathogenic bacteriaum that causes gastrointestinal disease in humans and many animals. PURPOSE The aim of this study was to investigate the effects of baicalin on S. typhimurium infection in mice and its possible mechanism in vitro. STUDY DESIGN To evaluate the effect of baicalin in vivo, mice were orally administered of baicalin, and then were infected by an intragastric administration of S. typhimurium. The minimal inhibitory concentrations (MICs) and minimum bactericidal concentrations (MBCs) of baicalin, baicalein, and oroxylin A against S. typhimurium were detected under the guides of the Clinical and Laboratory Standards Institute. In vitro, Caco-2 cells were infected with S. typhimurium in the presence or absence of baicalin, baicalein, and oroxylin A at sub-MICs. METHODS In the in vivo experiment, the body weight loss, the serum levels of TNFα, IL-6, and lactic dehydrogenase (LDH), the pathological changes of the caecum and the caecum bacterial burdens were examined. The MICs and MBCs of baicalin, baicalein, and oroxylin A against S. typhimurium were detected by two-fold serial dilutions. In vitro, Caco-2 cells were infected with S. typhimurium, and the invasion capacity, TNFα, nitrate, and LDH were analysed. The transcription levels of Salmonella pathogenicity island 1 virulence associated genes (sopB, sopE, sopE2) of S. typhimurium in the presence of baicalin, baicalein, and oroxylin A were detected by qRT-PCR. RESULTS Our results showed that baicalin significantly decreased the body weight loss, the serum levels of TNFα, IL-6, and LDH, and the caecum bacterial burdens of mice challenged with S. typhimurium. Histological examination showed that baicalin decreased the lesion in the caecum of S. typhimurium-infected mice. MICs and MBCs of baicalin, and oroxylin A. against S. typhimurium were > 128 µg/ml. MICs and MBCs of baicalein against S. typhimurium were 64 µg/ml, and > 128 µg/ml, respectively. Pretreatment of Caco-2 cells or S. typhimurium with baicalin, baicalein, and oroxylin A significantly inhibited the invasion of Caco-2 cells by S. typhimurium in a dose-dependent manner. Sub-MICs of baicalin, baicalein, and oroxylin A also significantly decreased the levels of TNFα, nitrate, and LDH from S. typhimurium-infected Caco-2 cells. Moreover, the transcription levels of sopB, sopE, and sopE2 were significantly suppressed by baicalin, baicalein, and oroxylin A. CONCLUSIONS These results demonstrated that baicalin is a promising agent for the prevention of S. typhimurium infection via the modulation of both bacterial virulence and host response.

Abstract
Four undescribed flavonoid alkaloids, as two pairs of enantiomers, were initially isolated as a racemate from the whole plant of Scutellaria moniliorrhiza. By means of chiral HPLC, four isomers, named scumonilines A-D, were successfully separated, and their chemical structures including absolute configurations were established by mass as well as NMR spectroscopy and CD technique. In vitro, four flavonoid alkaloids showed anti-inflammatory activities, with IC50 values against the release of β-glucuronidase from polymorphonuclear leukocytes of rats being in the range 5.16-5.85 μΜ. Moreover, four compounds were evaluated for their inhibitory activities against aldose reductase, and gave IC50 values in the range 2.29-3.03 μΜ.

Abstract
The widespread use of plants as accessible anticancer agents leads to the identification of many natural source chemotherapeutic agents. Scutellaria one of the popular genus of flowering plants has been used for various human illnesses for thousands of years. Scutellaria has anti-metastatic, anti-proliferative, anti-invasion, anti-angiogenic and apoptosis effects in vitro as well as in vivo. Despite numerous reports on the cytotoxic-antitumor activity of the plant, there are still some issues need further consideration. Issues such as unjustified interpretations, lack of attention to the pharmacokinetics profile and weak study design may affect the final decision about the use of plants as anticancer agents and possibly needs reconsideration. In this review, we have summarized the potential health benefits of Scutellaria and its active components also the underlying mechanism of cytotoxicity and antitumor activity. Meanwhile we have discussed concerns may interfere with the precise conclusion.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Experience-based herbal medicine as a complementary to modern western medicine has triggered an array of studies in quest of novel anticancer drugs. Scutellaria barbata D. Don (SB) is commonly used to treat different types of cancers, but its molecular mechanism of action is not clearly understood. In this study, we attempted to elucidate the mode of action of a traditional Chinese medicine prescription with a total of 14 components, named Lian-Jia-San-Jie-Fang (LJSJF, in Chinese), where SB works as the "principle" against non-small cell lung cancer (NSCLC) cells. MATERIALS AND METHODS Four different NSCLC cell lines (A549, H460, H1650, and H1975) were used. Cytotoxicity, in vitro tumorigenicity, gene expression, and protein expression were analyzed by MTT assay, soft agar assay, real-time PCR, and Western blots, respectively. RESULTS Among the 14 components in LJSJF, SB was the only one to possess cytotoxic effects at its pharmacologically relevant doses. Additionally, we observed synergistically dose-dependent cytotoxic effects of SB in combination with other LJSJF components. After SB or LJSJF treatment, significant reductions in colony number and/or size were observed in A549 and H460; a notable dose-dependent decrease in EGFR was observed in A549, H460, and H1650; significant downregulation in EGFR and its downstream signaling targets mTOR and p38MAPK were also observed in A549 and H460; and p53 and p21 were significantly increased while survivin, cyclin D1, and MDM2 were significantly decreased in A549. Additionally, p53, p21, and Mettl7b were decreased, but p73 was increased in H460. Neither EGFR nor p53 was changed in H1975. Therefore, SB or LJSJF may induce cytotoxic effects by regulating multiple and/or distinct apoptotic pathways in different NSCLC cells. CONCLUSION LJSJF exerts more pronounced cytotoxic effects against NSCLC cells than SB does by synergistically regulating the underlining molecular mechanisms including EGFR and/or p53 signaling pathways.

Abstract
A phytochemical study on Scutellaria formosana afforded five previously undescribed spiro-diterpenoids, scutellapenes A-E. The structures were elucidated on the basis of extensive 1D and 2D NMR spectroscopic data analysis, and the absolute configurations of these compounds were established by the time-dependent density functional theory (TDDFT) electronic circular dichroism (ECD) calculations. Scutellapenes B-E possess a spiro-diterpenoid skeleton. All of the compounds showed inhibitory effects on LPS-induced nitric oxide (NO) production in murine microglial BV-2 cells. The further molecular docking studies revealed that these bioactive compounds had strong interactions with the iNOS protein.

Abstract
Skullcap (Scutellaria baicalensis) is well known for its anti-inflammatory and anti-allergic effects. In our previous study, we found that skullcap could inhibit allergen permeation and regulate Th1/2 immune balance. To reveal the key fractions and components of skullcap, we fractionated skullcap extract into five fractions: hexane, chloroform, ethyl acetate, butanol, and water fraction. Among these fractions, the hexane fraction significantly suppressed the production of Th2-mediated cytokines (Interleukin (IL)-4, 5, 10 and 13) and increased Th1-mediated cytokines (Interferon (IFN)-γ and IL-12). Furthermore, the hexane fraction inhibited the permeation of ovalbumin (OVA), used as an allergen, across the intestinal epithelial cell monolayer. To confirm the active compounds in the hexane fraction, fatty acids were analyzed. Linoleic acid (LA, C18:2 (>59.7%)) was identified as the most important fatty acid in the skullcap hexane fraction. LA significantly suppressed IL-4 production and increased IFN-γ secretion, as well as inhibiting OVA permeation. Thus, LA significantly diminished the permeation of allergen by enhancing intestinal barrier function and regulated allergic responses to maintain Th1/Th2 immune balance.

Abstract
OBJECTIVE To investigate the effect of the ethanol extract of Scutellaria barbata D. Don (EESB) on colorectal cancer (CRC) growth and Wnt/β-catenin signaling pathway in vivo and in vitro. METHODS In vivo experiment, CRC xenograft mouse model was constructed with injection of HT-29 cells. Following xenograft implantation, twenty mice were randomly divided into EESB-treated group (n=10) and control group (n=10) by a random number table, and were given with intra-gastric administration of 2 g/kg EESB or saline, 5 days a week for 16 days, respectively. At the end of experiment, tumors were removed and weighed by electronic scales. The proliferation biomarker Ki-67 of tumor was evaluated by immunohistochemistry (IHC) assay. In vitro study, HT-29 cells were treated with 0, 0.5, 1.5, 2.5 mg/mL EESB for 24 h. At the end of the treatment, the viability and survival of HT-29 cells were determined by methylthiazolyldiphenyl-tetrazolium bromide (MTT) assay and colony formation assay, respectively. The mRNA expression of c-Myc, Survivin and adenomatous polyposis coli (APC) was examined by reverse transcription-polymerase chain reaction (RT-PCR) both in tumor tissues of CRC xenograft mice and HT-29 cells. Protein expression of c-Myc, Survivin, APC, and β-catenin as well as β-catenin phosphorylation level were evaluated by IHC assay or Western blotting. RESULTS EESB significantly reduced tumor weight in CRC xenografts mice, compared with the control group (P<0.05). IHC assay showed that EESB significantly inhibited protein expression of Ki-67 in tumor tissues (P<0.05). MTT assay showed that EESB significantly reduced HT-29 cell viability in a dose-dependent manner (P<0.05). Colony formation assay showed that EESB dose-dependently decreased the survival of HT-29 cells (P<0.05). In addition, RT-PCR assay showed that EESB decreased the mRNA expression of c-Myc and Survivin and increased APC expression, both in tumor tissues of CRC xenograft mice and HT-29 cells (P<0.05). IHC assay or Western blotting showed that EESB decreased protein expression of β-catenin, c-Myc and Survivin, as well as increased APC expression and β-catenin phosphorylation in tumor tissues or HT-29 cells (P<0.05). CONCLUSIONS EESB significantly reduced tumor growth in CRC xenografts mice, and inhibited the viability and survival of HT-29 cells. EESB could suppress the activation of the Wnt/β-catenin pathway, which might be one of the mechanisms whereby Scutellaria barbata D. Don exerts its anticancer activity.

Abstract
Aggregation of alpha-synuclein (α-SN) is a key pathogenic event in Parkinson's disease (PD) leading to dopaminergic degeneration. The identification of natural compounds inhibiting α-SN aggregation may have a major role in treating PD. Different Scutellaria species are known as valuable medicinal plants, primarily due to their high flavonoid levels. Scutellaria pinnatifida (S. pinnatifida) is endemic to Iran; however, the knowledge of its pharmaceutical properties is limited. Here we report that S. pinnatifida extracts have an anti-fibrillation effect on α-SN aggregation and neuroprotective properties on PC12 and primary dopaminergic neurons. Treatment during α-SN fibril formation with S. pinnatifida extracts showed that the extractions performed with dichloromethane (DCMEx) and n-butanol (BuOHEx) strongly inhibited α-SN fibrillation. TLC-based analysis revealed that S. pinnatifida contains a great amount of flavonoids with high antioxidant properties as shown using a radical scavenging assay. Further analysis using HPLC and Mass spectroscopy on the DCMEx revealed the presence of baicalein in this extract. We then selected the more efficient extracts based on cell viability and ROS scavenging on PC12 cells and tested their neuroprotective properties on primary dopaminergic neurons. Our results showed the extracts strongly protected against α-SN oligomers. Surprisingly, they also neutralized the severe toxicity of paraquat. Therefore, S. pinnatifida may be a potential valuable medicinal herb for further studies related to the treatment of PD.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Scutellaria barbata D. Don is a widely used medicinal herb in China. It possess various medicinal properties including antioxidative, anti-inflammatory and anti-cancer effects. The aim of this study was to explore whether Scutellaria barbata D. Don could inhibit the growth of ovarian cancer cells in vitro and further investigate the underlying mechanisms. MATERIALS AND METHODS Effects of Scutellaria barbata D. Don on the viability of ovarian cancer A2780 cells were measured by MTT assay. Apoptosis was measured by cell morphologic observation through DAPI staining and Annexin V-FITC staining assay for apoptosis analysis. The migration of ovarian cancer cells which exposed to Scutellaria barbata D. Don were measured by wound healing and transwell chamber assays. The protein levels of caspase 3/9, Bcl-2 and MMP-2/9 in human ovarian cancer cells treated with Scutellaria barbata D. Don were assessed by western blotting analysis. The potential bioactive compounds were characterized by HPLC-Q-TOF-MS. RESULTS The present study was to investigate the anticancer effects of crude extracts from Scutellaria barbata D. Don on ovarian cancer A2780 cells by MTT, DAPI staining, wound healing assay, transwell migration assay and western blotting analysis. Our study showed that Scutellaria barbata D. Don reduced the viability of A2780 cells and induced apoptosis by down-regulated Bcl-2 protein and increased Caspase 3/9 proteins. Furthermore, migration of A2780 cells were significantly inhibited by Scutellaria barbata D. Don and the underlying mechanism may be related to the decrease of MMP-2/9. The main constituents from Scutellaria barbata D. Don were identified to be thirteen flavonoids. A HPLC-Q-TOF-MS analysis of Scutellaria barbata D. Don indicated the presence of 14 flavonoids compounds, which may contribute to the anticancer activity of the Scutellaria barbata D. Don. CONCLUSIONS Scutellaria barbata D. Don could inhibit proliferation and induce apoptosis in A2780 cells through mitochondrial pathway. Moreover, the inhibitory effect of Scutellaria barbata D. Don on the migration of ovarian cancer cells was associated with the down-regulation of MMP-2/9 expression. These findings could shed a light on the therapy of ovarian cancer.

Abstract
BACKGROUND Scutellaria baicalensis is a well-known plant in traditional Chinese medicine. Recently, several Scutellaria species with therapeutic potential have been recognized worldwide. Scutellaria colebrookiana and Scutellaria violacea, native to the Western Ghats of India, are reported to possess free radical scavenging efficacy. At present, the protective effect of these Scutellaria spp. against 2,2' azobis (2-amidinopropane) hydrochloride (AAPH)-induced oxidative damage in human erythrocytes has been analyzed. METHODS Oxidative stress in erythrocyte was induced by AAPH. The inhibition of hemolysis, membrane lipid peroxidation, and protein damage by chloroform extracts of Scutellaria spp. was assessed biochemically. Phytochemicals of the extracts were analyzed by Fourier transform infrared spectrophotometer (FTIR). RESULTS Approximately 95% of erythrocytes were lysed by AAPH over 3 h of incubation. Significant reduction in hemolysis was observed by the extracts, and the IC50 values were 18.3 and 23.5 μg/mL for S. colebrookiana and S. violacea, respectively. Both the extracts were found to inhibit AAPH-induced lipid peroxidation in ghost membrane with IC50 92±2.8 and 70±5.6 μg/mL. In the analysis of the membrane proteins using sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE), the AAPH-induced degradation of actin was found reduced by both the extracts. The FTIR spectrum revealed the presence of polyphenols, carboxylic acids, alkanes, and aromatic compounds in extracts. In quantitative analysis, the total polyphenolic content estimated was 380±0.23 and 203.7±1.4 mg of gallic acid equivalent per gram extract of S. colebrookiana and S. violacea. CONCLUSIONS Results indicate that S. colebrookiana and S. violacea are capable of protecting erythrocytes from oxidative damage. This cytoprotective effect of the extract is possibly by its antioxidant property.

Abstract
Fourteen neo-clerodane diterpenoids isolated from Scutellaria altissima (Lamiaceae) were tested for insect antifeedant activity against Leptinotarsa decemlineata Say. Potato leaf disks treated with small amounts of the compounds (concentration 1000, 100, 10 ppm) resulted in good to very good antifeedant activity. Clerodin (1), scutecyprin (11) and 11-epi-scutecolumnin C (12) showed strong feeding inhibition at 1000 ppm and exhibited significant antifeedant activity at a concentration of 100 ppm. Activity was established by calculating the feeding ratio (FR) between the consumed areas of treated disks (CTD) and control disks (CCD). For comparison, FR50 values were determined as the FR at a CCD of 50%. Structural features of the compounds associated with the changes in activity and structure-antifeedant activity relationships are discussed. For the first time the anti-feedant activity has been evaluated of neo-clerodane diterpenoids with an unusual R-configuration of the carbon atom C-I 1.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Radix Scutellariae (Scutellaria baicalensis Georgi, RS), a traditional herbal medicine commonly used to treat inflammation, hypertension, cardiovascular disease, bacterial and viral infections, is reported to treat lung cancer by supplements of modern medicine. The total flavonoid aglycones extract (TFAE) from RS is the most important composition for the pharmacodynamic effects. The present study was designed to evaluate the anti-lung tumor effect of TFAE on A549 cells and A549 cell nude mice xenografts. The aim of the study is to investigate the effect and mechanism of TFAE treating non-small cell lung cancer both in vitro and in vivo. MATERIALS AND METHODS The anti-tumor activity of TFAE in vitro was investigated using the MTT assay. The changes of cell invasion and migration were detected by Transwell assay and tube formation experiments were used to detect the anti-angiogenic effect. The anti-tumor effects of TFAE in vivo were evaluated in A549 cell nude mice xenografts. The mechanism of TFAE was detected by flow cytometry technology, western blot assay and immuno-histochemistry assay. RESULTS In vitro, TFAE inhibited the proliferation, invasion and migration of A549 cells in a dose- and time-dependent manner. In vivo, TFAE by oral administration at 100mg/kg for 30 days decreased the tumor volume and tumor weight in A549 cell xenograft by 25.5% with no statistical significance (P<0.05) compared to the cis-platinum positive control group (30.0%). The cell cycle and DNA synthesis experiment illustrated that TFAE could induce A549 cell cycle to arreste in S phase and DNA synthesis in A549 cells be inhibited, while TFAE had no influence on apoptosis of A549 cells. Western Blot assay demonstrated that the treatment of TFAE could make Cyclin D1 decrease and p53 increase both in vitro and in vivo. CONCLUSION TFAE displayed the inhibition effects of non-small cell lung cancer both in vitro and in vivo and the underlying mechanism might be related to the increased p53 protein expression and decreased Cyclin D1 expression, leading to cell cycle arrested in S phase and the decrease of DNA synthesis.

Abstract
To explore the effect of total flavonoids of Scutellaria barbata on cognitive function and nogo-A expression in the hippocampus region in cerebral ischemia model in gerbils. 30 gerbils were randomly divided into model group, sham operation group, large dose of total flavonoids of Scutellaria barbata group (large dose group), middle dose of total flavonoids of Scutellaria barbata group (middle dose group) and small dose of total flavonoids of Scutellaria barbata group (small dose group), with 6 cases in each group. All the groups except the sham operation group were received bilateral common carotid artery ligation to establish the cerebral ischemia model in gerbils. After that, the large, middle and small doses groups were given 400mg/kg, 200mg/kg and 100mg/kg of total flavonoids of Scutellaria barbata respectively, while the other two groups were injected with sodium chloride for 4 continuous weeks. At the 5th and 8th week after modeling, the cognitive function (e.g. escape latency period and original platform crossing times) of the gerbils in the three groups were detected by Morris water maze test. Moreover, the nogo-A expressions in the hippocampus region were detected by immunohistochemical staining method at the 8th week. The escape latency period and platform crossing times at the 5th and 8th week after modeling in the large dose group were significantly higher than the rest groups (except slam operation group) (p<0.05), while the difference was not significant when compared with slam operation group (p>0.05). The difference of the gray value of nogo-A positive cells in hippocampus in the large dose group was not significant compared with middle dose group and sham operation group (p>0.05), while it was significant compared with model group and small dose group (p<0.05). Large dose of total flavonoids of Scutellaria barbata can obviously improve the cognitive function in cerebral ischemia model in gerbils by reducing nogo-A expression in the hippocampus region.

Abstract
Methanolic extracts from the aerial parts and roots of two Scutellaria species, S. alpina and S. altissima, and five polyphenols from these plants demonstrated a significant ability to inhibit the formation of advanced glycation end-products (AGE) in vitro. S. alpina, which is richer in polyphenolic compounds, had strong antiglycation properties. These extracts demonstrated also high activity in the FRAP (ferric-reducing antioxidant power), antiradical (DPPH) and lipid peroxidation inhibition assays. Among the pure compounds, baicalin was the strongest glycation inhibitor (90.4% inhibition at 100 μg/mL), followed by luteolin (85.4%). Two other flavone glycosides had about half of this activity. Verbascoside was similar to the reference drug aminoguanidine (71.2% and 75.9%, respectively). The strong correlation observed between AGE inhibition and total flavonoid content indicated that flavonoids contribute significantly to antiglycation properties. A positive correlation was also observed between antiglycative and antioxidant activities. The studied skullcap species can be considered as a potential source of therapeutic agents for hyperglycemia-related disorders.

Abstract
This study was conducted to test the protective activity of ethanol extract of Herba Scutellariae Barbatae(SE) against hepatotoxicity induced by Rhizoma Dioscoreae Bulbiferae in mice and its mechanism. SE was orally given to mice at various doses, and ethyl acetate fraction of Rhizoma Dioscoreae Bulbiferae(EF, 450 mg·kg(-1)) was also orally given at the same time. After 11 days, serum levels of alanine/aspartate aminotransferase(ALT/AST), alkaline phosphatase(ALP), total protein(TP) and albumin(ALB) were measured, and liver histological examination was conducted. Liver glutathione(GSH) amount, myeloperoxidase(MPO) activity and serum tumor necrosis factor-α(TNF-α), interleukin-6(IL-6) and interferon-γ(IFN-γ) levels were measured. The expression of heme oxygenase-1(HO-1), inhibitor of kappa B(IκB) and nuclear factor κB(NF-κB) p65 were determined by Western blot. The results showed that SE(200 mg·kg-1) reversed EF-induced changes of serum ALT, AST, ALP, TP and ALB. Liver histology also suggests the protection of SE against EF-induced liver injury. SE reduced the increased MPO activity in liver and TNF-α, IL-6, IFN-γ contents in serum, and blocked the decrease in IκB expression and subsequent increase in phosphorylation and nuclear translocation of p65 induced by EF. EF increased liver GSH amount and heme oxygenase-1(HO-1) protein expression in mice. SE increased liver GSH amount, but decreased the expression of HO-1. All those results suggest that SE alleviates liver injury induced by consecutive administration of EF by alleviating inflammatory injury via inhibiting NF-κB signaling pathway and elevating antioxidant capacity.

Abstract
UNLABELLED The skin burns are an issue of great interest and seriousness in the public health domain, by their destructive features. Natural medicinal products are extensively used from ancient times, in ethnopharmacology, for the treatment of skin injuries (burns, wounds, ulcerations) due to the local modulation of the cellular response, in terms of emollient, demulcent, astringent, anti-inflammatory, antimicrobial, epithelizing, wound-healing, immunomodulatory and antioxidant effects. AIM Histological and immunohistochemical assessment of antiseptic, anti-inflammatory, astringent and cicatrizing effects of Scutellariae (altissimae, galericulatae, hastifoliae) herba extracts administered in the form of 20% topical preparations (cold-creams), in experimental model of third degree skin burns, at Wistar rats. Caffeic acid and chlorogenic acid derivatives were identified in all herbal samples. The most active was the cold-cream with 20% Scutellariae hastifoliae herba soft extract, promoting the neoangiogenesis vessels and granulation tissue. Flavonoids, tannins and polyphenol carboxylic acids are the main active principles responsible for antiseptic, anti-inflammatory, astringent and cicatrizing effects of herbal extracts. Beeswax, from the formulation of cold-creams, acts as emollient, epithelizing, cicatrizing and biostimulator.
