Abstract
Endophytes are microorganisms that inhabit various plant parts and cause no damage to the host plants. During the last few years, a number of novel endophytic fungi have been isolated and identified from medicinal plants and were found to be utilized as bio-stimulants and bio fertilizers. In lieu of this, the present study aims to isolate and identify endophytic fungi associated with the leaves of Anisomeles indica L. an important medicinal plant of the Terai-Duars region of West Bengal. A total of ten endophytic fungi were isolated from the leaves of A. indica and five were identified using ITS1/ITS4 sequencing based on their ability for plant growth promotion, secondary metabolite production, and extracellular enzyme production. Endophytic fungal isolates were identified as Colletotrichum yulongense Ai1, Colletotrichum cobbittiense Ai2, Colletotrichum alienum Ai2.1, Colletotrichum cobbittiense Ai3, and Fusarium equiseti. Five isolates tested positive for their plant growth promotion potential, while isolates Ai4. Ai1, Ai2, and Ai2.1 showed significant production of secondary metabolites viz. alkaloids, phenolics, flavonoids, saponins, etc. Isolate Ai2 showed maximum total phenolic concentration (25.98 mg g-1), while isolate Ai4 showed maximum total flavonoid concentration (20.10 mg g-1). Significant results were observed for the production of extracellular enzymes such as cellulases, amylases, laccases, lipases, etc. The isolates significantly influenced the seed germination percentage of tomato seedlings and augmented their growth and development under in vitro assay. The present work comprehensively tested these isolates and ascertained their huge application for the commercial utilization of these isolates both in the agricultural and industrial sectors.

Antioxidants (Basel) 2022; 11:antiox11122327. [PMID: 36552535 PMCID: PMC9774812 DOI: 10.3390/antiox11122327] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/29/2022] [Revised: 11/15/2022] [Accepted: 11/22/2022] [Indexed: 11/27/2022] Open
Abstract
Gastric ulcers are commonly seen in the upper gastrointestinal tract and may be related to the Helicobacter pylori infection and the use of aspirin, a nonsteroidal anti-inflammatory drug (NSAID). Typically, proton-pump inhibitors (PPIs) are used to treat gastric ulcers; however, adverse effects have emerged following long-term treatment. Natural medicines are used as alternative therapeutic agents in the treatment of gastric ulcers, with few side effects. Despite various reports on the anti-H. pylori and anti-gastric cancer activities of Anisomeles indica, its gastroprotective effect on ulcers remains undetermined. This study investigated the protective effect of A. indica on aspirin-induced gastric ulcers in murine models. Our results show that three fractions of ethanol-extracted A. indica inhibited aspirin-induced gastric injury. Among these, A. indica Fraction 1 was observed to enrich ovatodiolide, which effectively diminished gastric acidity and alleviated aspirin-induced inflammation in the stomach. Our results provide evidence that A. indica could be developed as an effective therapeutic agent for gastroprotective purposes.

Innovative Purification Method of Ovatodiolide from Anisomeles indica to Induce Apoptosis in Human Gastric Cancer Cells. Molecules 2022; 27:molecules27030587. [PMID: 35163851 PMCID: PMC8839775 DOI: 10.3390/molecules27030587] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2021] [Revised: 01/14/2022] [Accepted: 01/15/2022] [Indexed: 12/24/2022] Open
Abstract
Ovatodiolide (Ova), found in the plant Anisomeles indica (AI), has been reported to have an anti-proliferation effect in various cancer cells. However, little information is available regarding the anti-cancer effect of Ova in human gastric cancer cells. In this study, we investigated the inhibitory effects and the mechanisms of action responsible for these effects on human AGS cell lines from a newly developed purification technique for Ova from AI extract. Extract obtained at the optimum condition of 95% ethanol extraction of AI was sequentially partitioned by using different polarity solvents. Enriched content of Ova (35.9% purity) from the n-hexane fraction was then applied to the purification by using centrifugal partition chromatography (CPC) in a two-phase solvent system consisting of n-hexane:ethyl acetate:methanol:water (1.0:1.0:1.0:1.0, v/v/v/v) to reach purity over >95.0%. In evaluation of the anti-proliferation effect on AGS cells, Ova induced cell apoptosis with IC50 values of 13.02 and 6.18 μM at 24 and 48 h, respectively, and arrested the cells at the G2/M phase. Quantification of Bax/Bcl2 mRNA expressions using qPCR showed a 2.5-fold increase in the Ova (5 μM)-treated cells at 48 h than in the control group. Specific protein expression data warrant further research to further confirm the proposed Ova-induced apoptotic pathway in AGS cells.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The species of the genus Cirsium have been used as traditional Chinese medicine for hundreds of years. It is believed that Cirsium has the efficacies of cooling blood and stopping bleeding, dispelling blood stasis, detoxifying and eliminating carbuncle. At present, they are mainly used in treatment of the hemoptysis, hematemesis, hemoptysis, hematuria, traumatic bleeding and Henoch-Schonlein purpura. They are widely used in traditional Chinese medicine. AIM This paper systematically collated the classification, traditional use, pharmacological action, phytochemistry and clinical application of Cirsium plants in the past ten years, intending to provide a critical appraisal of current knowledge for future in-depth study and rational development and utilization of Cirsium plants. MATERIAL AND METHODS This paper searched various databases (SciFinder, Science Direct, CNKI, Wiley online library, Spring Link, Web of Science, PubMed, Wanfang Data, Weipu Data), Chinese Pharmacopoeia 2020 Edition, Chinese Flora, Chinese Materia Medica and some local books on ethnopharmacology. RESULTS More than ten species of Cirsium have been used as folk medicine, and modern pharmacological studies have shown that Cirsium has the effects of protecting liver, antioxidation, anti-tumor, anti-inflammation, antibacterial, etc. More than 200 chemical constituents such as flavonoids, triterpenes, sterols, phenylpropanoids have been isolated from Cirsium. Some ingredients show a wide variety of bioactivities including hepatoprotective, anti-inflammatory, antioxidant, anti-tumor and other activities. At present, Cirsium medicinal plants, as traditional Chinese medicine, were mainly used to treat nephritis, Henoch-Schonlein purpura and hemorrhage, although some species used in folk lack of quality control systems. CONCLUSION Cirsium plants are a safe and effective medicine for cooling blood and hemostasis. Recent studies on pharmacology and phytochemistry also provide solid scientific evidences for the traditional application of this genus. It also shows significant hepatoprotective activity and may be a potential clinical candidate for the treatment of liver disease. However, the qualitative and quantitative analysis, pharmacokinetics-pharmacodynamics and mechanism of action also need in-depth study.

Ovatodiolide inhibits the oncogenicity and cancer stem cell-like phenotype of glioblastoma cells, as well as potentiate the anticancer effect of temozolomide. PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2019; 61:152840. [PMID: 31035045 DOI: 10.1016/j.phymed.2019.152840] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/09/2018] [Revised: 12/08/2018] [Accepted: 12/22/2018] [Indexed: 06/09/2023]
Abstract
BACKGROUND Ovatodiolide (Ova), a major bioactive diterpenoid isolate of Anisomeles indica has drawn considerable attention lately as an effective anticancer agent with several published works demonstrating its tumor-inhibitory activity in various cancer types. PURPOSE In this study, we examined the modulatory effect of Ova on the oncogenicity, proliferation, and cancer stem cell-like traits of glioblastoma (GBM) cells, as well as investigated the underlying molecular mechanism for the anticancer activity of Ova in GBM cell lines, U-87MG and GBM8401. METHODS The antiproliferative, apoptotic, and stemness-attenuating effects of Ova were evaluated using the sulforhodamine B (SRB) colorimetric assay, western blot and fluorescent immunocytochemistry. Cell apoptosis was analyzed based on variation in the expression levels of Bcl-2 family of regulator proteins Bax, Bak, Bcl-2 and Bcl-xL. RESULTS Ova induced the apoptosis of the U-87MG and GBM8401 cells, as well as effectively inhibited the proliferation and motility of the GBM cell lines in a dose- and time-dependent manner. Ova-induced apoptosis correlated with increased Bax/Bcl-2 ratio, while inhibition of tumor cell migration and colony formation was associated with reduced Slug, Vimentin, NCadherin and β-catenin protein expression and increased E-Cadherin. In addition, exposure to Ova inhibited tumorsphere formation, elicited downregulation of CD44, CD133, Sox2, and Oct4, as well as correlated with dysregulation of the JAK2-STAT3 signaling pathway. Furthermore, we showed for the first time to the best of our knowledge that Ova potentiate the chemotherapeutic effect of Temozolomide. CONCLUSION Taken together, our findings demonstrate the anticancer potential of Ova in GBM and its efficacy in the treatment of GBM as monotherapy and in combination with Temozolomide.

Abstract
Helicobacter pylori infection is associated with high incidence of gastric diseases. The extensive therapy of H. pylori infection with antibiotics has increased its resistance rates worldwide. Ovatodiolide, a pure constituent isolated from Anisomeles indica, has been demonstrated to possess bactericidal activity against H. pylori. In this study, ovatodiolide inhibited the growth of both H. pylori reference strain and clinical multidrug-resistant isolates. Docking analysis revealed that ovatodiolide fits into the hydrophobic pocket of a ribosomal protein, RpsB. Furthermore, ovatodiolide inhibited bacterial growth by reducing levels of RpsB, which plays a crucial role in protein translation. Our results demonstrate that ovatodiolide binds to a ribosomal protein and interferes with protein synthesis. This study provides evidence that ovatodiolide has the potential to be developed into a potent therapeutic agent for treating H. pylori infection.

Abstract
Plantaginis Semen is commonly used in traditional medicine to treat edema, hypertension, and diabetes. The commercially available Plantaginis Semen in China mainly comes from three species. To clarify the chemical composition and distinct different species of Plantaginis Semen, we established a metabolite profiling method based on ultra high performance liquid chromatography with electrospray ionization quadrupole time-of-flight tandem mass spectrometry coupled with elevated energy technique. A total of 108 compounds, including phenylethanoid glycosides, flavonoids, guanidine derivatives, terpenoids, organic acids, and fatty acids, were identified from Plantago asiatica L., P. depressa Willd., and P. major L. Results showed significant differences in chemical components among the three species, particularly flavonoids. This study is the first to provide a comprehensive chemical profile of Plantaginis Semen, which could be involved into the quality control, medication guide, and developing new drug of Plantago seeds.

Abstract
Asthma, a complex pulmonary allergic disease, major therapy is applied of drugs to control the disease, but quickly recur after the drugs are stopped. In patients with severe asthma may show steroid resistance and would benefit from the development of novel therapeutic drugs. Ovatodiolide, a unique macrocyclic diterpenoid isolated from Anisomeles indica, showed therapeutic potential for the treatment of allergic asthma. As a model of allergic inflammation, we used ovalbumin (OVA)-immunized mice, which displayed T helper cell type 2 (TH2) cytokine expression in bronchoalveolar lavage fluid (BALF), as well as airway inflammation and hyperresponsiveness (AHR). The results showed that ovatodiolide suppressed TH2 activation, including cell proliferation and production of the TH2 related cytokines, interleukin (IL)-4, IL-5, IL-13, IL-33, eosinophil chemotactic protein (eotaxin), and also reduced airway hyperresponsiveness. In this study, ovatodiolide inhibited allergic asthma through downregulation of TH2 responses in a murine model of asthma.

Abstract
Resveratrol (RV, 3,4ʹ,5-trihydroxystilbene) is naturally produced by a wide variety of plants including grapes and peanuts (Arachis hypogaea). However, the yield of RV from peanut stem and its potential radiosensitizing effects in prostate cancer (PCa) have not been well investigated. In this study, we characterized RV in peanut stem extract (PSE) for the first time and showed that both RV and PSE dose-dependently induced cell death in DOC-2/DAB2 interactive protein (DAB2IP)-deficient PCa cells with the radioresistant phenotype. Furthermore, the combination of radiation with either RV or PSE induced the death of radioresistant PCa cells through delayed repair of radiation-induced DNA double-strand break (DSB) and prolonged G2/M arrest, which induced apoptosis. The administration of RV and PSE effectively enhanced radiation therapy in the shDAB2IP PCa xenograft mouse model. These results demonstrate the promising synergistic effect of RV and PSE combined with radiation in the treatment of radioresistant PCa.

Abstract
A variety of approaches have been proposed for overcoming the unpleasant side effects associated with antibiotics treatment of Helicobacter pylori (H. pylori) infections. Research has shown that epigallocatechin-3-gallate (EGCG), a major ingredient in green tea, has antibacterial activity for antiurease activity against H. pylori. Oral EGCG is not good because of its digestive instability and the fact that it often cannot reach the targeted site of antibacterial activity. To localize EGCG to H. pylori infection site, this study developed a fucose-chitosan/gelatin nanoparticle to encapsulate EGCG at the target and make direct contact with the region of microorganisms on the gastric epithelium. Analysis of a simulated gastrointestinal medium indicated that the proposed in vitro nanocarrier system effectively controls the release of EGCG, which interacts directly with the intercellular space at the site of H. pylori infection. Meanwhile, results of in vivo clearance assays indicated that our prepared fucose-chitosan/gelatin/EGCG nanoparticles had a significantly greater H. pylori clearance effect and more effectively reduced H. pylori-associated gastric inflammation in the gastric-infected mouse model than the EGCG solution alone.

Abstract
Phellinus linteus and its constituent hispolon induce potent anti-inflammatory activity in macrophages. Efficient production of the effective constituent and the biological function of P. linteus in the regulation of innate sensing have rarely been investigated. The aim of this study was to efficiently manufacture P. linteus-fermented broth containing the effective constituent, hispolon, and evaluate its immunoregulatory functions in macrophages. Four distinct fermented broths (PL1-4) and the medium dialyzate (MD) were prepared to screen suitable culture conditions for the mycelial growth of P. linteus. The P. linteus-fermented broth exhibited a dose-responsive inhibition of lipopolysaccharide (LPS)-induced nitric oxide (NO) production by murine macrophages. In addition, the P. linteus-fermented broths suppressed macrophage LPS-mediated nuclear factor (NF)-κB activity and tumor necrosis factor (TNF)-α. Among the tested samples from P. linteus, PL4 contained vast amounts of hispolon and showed the greatest anti-inflammatory activity in both the RAW264.7 cells and murine primary peritoneal exudate macrophages (PEMs). This study demonstrates that the purification of the effective constituent from P. linteus-fermented broth may enable the production of a potent therapeutic agent for anti-inflammation in macrophages.

Abstract
The antimicrobial effect of a novel flavonoid (7-O-butylnaringenin) on Helicobacter pylori 26695, 51, and SS1 strains and its inhibitory effect on the urease activity of the strains were evaluated and compared with those of several natural flavonoids. First, various flavonoids were screened for antimicrobial activities using the paper disc diffusion method. Hesperetin and naringenin showed the strongest antimicrobial effects among the natural flavonoids tested, and thus hesperetin and naringenin were selected for comparison with 7-O-butylnaringenin. The antimicrobial effect of 7-O-butylnaringenin was greater than that of the hesperetin and naringenin. H. pylori 51 was more sensitive to 7-O-butylnaringenin (2 log reduction of colony forming units, p < 0.05) than the other two strains at 200 μM. 7-O-Butylnaringenin also showed the highest inhibitory effect against urease activity of H. pylori. Morphological changes of H. pylori 26695 treated with these flavonoids indicated that both hesperetin and 7-O-butylnaringenin at 200 μM damaged the cell membranes.

Ovatodiolide Targets β -Catenin Signaling in Suppressing Tumorigenesis and Overcoming Drug Resistance in Renal Cell Carcinoma. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2013; 2013:161628.

Abstract
Dysregulated β-catenin signaling is intricately involved in renal cell carcinoma (RCC) carcinogenesis and progression. Determining potential β-catenin signaling inhibitors would be helpful in ameliorating drug resistance in advanced or metastatic RCC. Screening for β-catenin signaling inhibitors involved in silico inquiry of the PubChem Bioactivity database followed by TCF/LEF reporter assay. The biological effects of ovatodiolide were evaluated in 4 RCC cell lines in vitro and 2 RCC cell lines in a mouse xenograft model. The synergistic effects of ovatodiolide and sorafenib or sunitinib were examined in 2 TKI-resistant RCC cell lines. Ovatodiolide, a pure compound of Anisomeles indica, inhibited β-catenin signaling and reduced RCC cell viability, survival, migration/invasion, and in vitro cell or in vivo mouse tumorigenicity. Cytotoxicity was significantly reduced in a normal kidney epithelial cell line with the treatment. Ovatodiolide reduced phosphorylated β-catenin (S552) that inhibited β-catenin nuclear translocation. Moreover, ovatodiolide decreased β-catenin stability and impaired the association of β-catenin and transcription factor 4. Ovatodiolide combined with sorafenib or sunitinib overcame drug resistance in TKI-resistant RCC cells. Ovatodiolide may be a potent β-catenin signaling inhibitor, with synergistic effects with sorafenib or sunitinib, and therefore, a useful candidate for improving RCC therapy.

Abstract
Helicobacter pylori infection is one of the most critical causes of stomach cancer. The current study was conducted to explore the protective effects of an isolated active peptide H-P-6 (Pro-Gln-Pro-Lys-Val-Leu-Asp-Ser) from microbial hydrolysates of Chlamydomonas sp. against H. pylori-induced carcinogenesis. The peptide H-P-6 has effectively suppressed H. pylori-induced hyper-proliferation and migration of gastric epithelial cells (AGS). However, the peptide did not inhibit the viability of the bacteria or invasion into AGS cells. Therefore, the effect of the peptide on regulating H. pylori-induced molecular signaling was investigated. The results indicated that H. pylori activates the EGFR tyrosine kinase signaling and nuclear translocation of the β-catenin. The EGFR activation has led to the up-regulation of PI3K/Akt signaling pathway. Moreover, the nuclear translocation levels of β-catenin were significantly increased as a result of Akt mediated down-regulation of GSK3/β protein levels in the cytoplasm. Both of these consequences have resulted in increased expression of cell survival and migration related genes such as c-Myc, cyclin-D, MMP-2 and matrilysin. Interestingly, the isolated peptide potently inhibited H. pylori-mediated EGFR activation and thereby down-regulated the subsequent P13K/Akt signaling leading to β-catenin nuclear translocation. The effect of the peptide was confirmed with the use of EGFR tyrosine kinase inhibitor AG1487 and molecular docking studies. Collectively this study identifies a potent peptide which regulates the H. pylori-induced hyper-proliferation and migration of AGS cells at molecular level.

Abstract
The purpose of the study was to investigate the antioxidant characteristics of Anisomeles indica methanol extract and the inhibitory effect of ovatodiolide on melanogenesis. In the study, the antioxidant capacities of A. indica methanol extract such as DPPH assay, ABTS radical scavenging assay, reducing capacity and metal ion chelating capacity as well as total phenolic content of the extract were investigated. In addition, the inhibitory effects of ovatodiolide on mushroom tyrosinase, B16F10 intracellular tyrosinase and melanin content were determined spectrophotometrically. Our results revealed that the antioxidant capacities of A. indica methanol extract increased in a dose-dependent pattern. The purified ovatodiolide inhibited mushroom tyrosinase activity (IC50 = 0.253 mM), the compound also effectively suppressed intracellular tyrosinase activity (IC50 = 0.469 mM) and decreased the amount of melanin (IC50 = 0.435 mM) in a dose-dependent manner in B16F10 cells. Our results concluded that A. indica methanol extract displays antioxidant capacities and ovatodiolide purified from the extract inhibited melanogenesis in B16F10 cells. Hence, A. indica methanol extract and ovatodiolide could be applied as a type of dermatological whitening agent in skin care products.
