Lien HM, Wang YY, Huang MZ, Wu HY, Huang CL, Chen CC, Hung SW, Chen CC, Chiu CH, Lai CH. Gastroprotective Effect of Anisomeles indica on Aspirin-Induced Gastric Ulcer in Mice. 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.

Genotoxicity and 28-day repeated dose oral toxicity study of ovatodiolide in rats. Toxicol Rep 2021; 8:1783-1791. [PMID: 34722163 PMCID: PMC8536504 DOI: 10.1016/j.toxrep.2021.10.010] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/21/2021] [Revised: 09/27/2021] [Accepted: 10/09/2021] [Indexed: 12/18/2022] Open
Abstract
Ovatodiolide is a bioactive cembrane-type diterpenoid isolated from Anisomeles indica (L.) Kuntze. It has been proven that ovatodiolide is anti-inflammatory, anti-tumorigenic, anti-melanogenic and attenuates asthma by regulating signaling pathways. The aim of this study was to evaluate the safety of ovatodiolide by conducting genotoxicity tests and 28-day oral toxicity tests in rats. Genotoxicity assays were conducted by using a bacterial reverse mutation test and mammalian chromosomal aberration test to assess whether ovatodiolide causes reverse mutations and mutagenicity with or without metabolism activation. For the in vivo mammalian erythrocyte micronucleus test, mice were administered a single dose of 0, 250, 500 or 1000 mg/kg b.w. ovatodiolide by single gavage. In the acute oral toxicity test, rats were given a single dose of ovatodiolide 1000 mg/kg b.w. by single gavage. In the 28-day oral toxicity test, groups were divided into a control, ovatodiolide 10, 25 and 50 mg/kg b.w. The results showed that there was no mutagenicity in the bacterial reverse mutation test or the mammalian chromosomal aberration test with or without S9 fraction. Ovatodiolide did not produce an increase in micronucleated reticulocytes in the micronucleus test. The results revealed that the acute oral toxicity of ovatodiolide is over 1000 mg/kg b.w. in rats. Moreover, 10, 25 and 50 mg/kg b.w. of ovatodiolide did not cause a significant effect in rats. According to the results of the genotoxicity and oral toxicity studies in rats, ovatodiolide did not produce any adverse effects, and the tested doses can serve as clinical references.

Toxicity and Anti-Proliferative Properties of Anisomeles indica Ethanol Extract on Cervical Cancer HeLa Cells and Zebrafish Embryos. Life (Basel) 2021; 11:257. [PMID: 33804714 PMCID: PMC8003830 DOI: 10.3390/life11030257] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/27/2021] [Revised: 03/13/2021] [Accepted: 03/18/2021] [Indexed: 01/14/2023] Open
Abstract
In this study, we showed that crude extract of Anisomeles indica (AI-EtE) expressed its toxicity to HeLa cells with an IC50 dose of 38.8 µg/mL and to zebrafish embryos with malformations, lethality and hatching inhibition at 72-hpf at doses higher than 75 µg/mL. More interestingly, flow cytometry revealed that AI-EtE significantly promoted the number of cells entering apoptotic. Accordingly, the transcript levels of BAX, CASPASE-8, and CASPASE-3 in the cells treated with AI-EtE at IC50 dose were 1.55-, 1.62-, and 2.45-fold higher than those in the control cells, respectively. Moreover, treatment with AI-EtE caused cell cycle arrest at the G1 phase in a p53-independent manner. Particularly, percentages of AI-EtE-treated cells in G1, S, G2/M were, respectively 85%, 6.7% and 6.4%; while percentages of control cells in G1, S, G2/M were 64%, 15% and 19%, respectively. Consistent with cell cycle arrest, the expressions of CDKN1A and CDNK2A in AI-EtE-treated cells were up-regulated 1.9- and 1.64-fold, respectively. Significantly, treatment with AI-EtE also decreased anchorage-independent growth of HeLa cells. In conclusion, we suggest that Anisomeles indica can be considered as a medicinal plant with a possible use against cervical cancer cells; however, the used dose should be carefully monitored, especially when applying to pregnant women.

Ovatodiolide, isolated from Anisomeles indica, suppresses bladder carcinogenesis through suppression of mTOR/β-catenin/CDK6 and exosomal miR-21 derived from M2 tumor-associated macrophages. Toxicol Appl Pharmacol 2020; 401:115109. [PMID: 32544403 DOI: 10.1016/j.taap.2020.115109] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/16/2020] [Revised: 06/04/2020] [Accepted: 06/06/2020] [Indexed: 12/22/2022]
Abstract
Bladder cancer (BCa) is the fourth leading cause of cancer deaths worldwide due to its aggressiveness and resistance against therapies. Intricate interactions between cancer cells and the tumor microenvironment (TME) are essential for both disease progression and regression. Thus, interrupting molecular communications within the TME could potentially provide improved therapeutic efficacies. M2-polarized tumor-associated macrophages (M2 TAMs) were shown to contribute to BCa progression and drug resistance. We attempted to provide evidence for ovatodiolide (OV) as a potential therapeutic agent that targets both TME and BCa cells. First, tumor-suppressing functions of OV were determined by cell viability, colony, and tumor-sphere formation assays using a coculture system composed of M2 TAMs/BCa cells. Subsequently, we demonstrated that extracellular vesicles (EVs) isolated from M2 TAMs containing oncomiR-21 and mRNAs, including Akt, STAT3, mTOR, and β-catenin, promoted cisplatin (CDDP) resistance, migration, and tumor-sphere generation in BCa cells, through increasing CDK6, mTOR, STAT3, and β-catenin expression. OV treatment also prevented M2 polarization and reduced EV cargos from M2 TAMs. Finally, in vivo data demonstrated that OV treatment overcame CDDP resistance. OV only and the OV + CDDP combination both resulted in significant reductions in mTOR, β-catenin, CDK6, and miR-21 expression in tumor samples and EVs isolated from serum. Collectively, we demonstrated that M2 TAMs induced malignant properties in BCa cells, in part via oncogenic EVs. OV treatment prevented M2 TAM polarization, reduced EV cargos derived from M2 TAMs, and suppressed β-catenin/mTOR/CDK6 signaling. These findings provide preclinical evidence for OV as a single or adjuvant agent for treating drug-resistant BCa.

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
BACKGROUND Treatment for metastatic nasopharyngeal carcinoma (NPC) is challenging. Till now, a truly effective chemotherapy regimen for NPC has not yet been identified. These clinical observations prompted us to investigate a potential drug as alternative option for treating. PURPOSE This study evaluated the inhibitory effects of Ovatodiolide (Ova), on tumorigenic and cancer stem cell characteristics of NPC cells. METHODS Two NPC cell lines (NPC-BM1 and NPC-BM2) were used to examine the anticancer effects of Ova and the molecular mechanism underlying these activities by using sulforhodamine B cytotoxicity assay, western blot, immunofluorescence, migration, colony and tumorsphere formation assays. RESULTS Ova significantly inhibited the viability of BM1 and BM2 cells, downregulated Bcl-xL and Puma, and upregulated Bax/Bad expression levels. Ova dose-dependent suppressed migratory/invasive potential of NPC cells, and reduced ability to form colonies. Ova-induced apoptosis correlated with increased Bax/Bcl-xL ratio while NPC motility and colony formation inhibition were associated with reduced expression of p-FAK, p-PXN, F-actin, and Slug proteins and increased E-cadherin. Furthermore, ova inhibited NPC tumorsphere formation, associated with decreased SOX2, OCT4 and JAK-STAT signaling pathway. Ova also attenuated NPC stem cell tumorigenicity, inhibited tumor growth, and enhanced the sensitivity of NPC cells to cisplatin treatment, in vivo. CONCLUSIONS Our results demonstrated the anticancer efficacy of Ova in NPC and its potential as a putative inhibitor of JAK2 and STAT3, which are essential in tumorigenesis of NPC. Further development of Ova is encouraged.

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
OBJECTIVE Increasing numbers of cancer patients are using Chinese herbs (CHs). However, differences among prior studies make it difficult to draw firm conclusions about the clinical usefulness of any specific CH formula. The primary objective of this study was to establish the acceptability of taking a standardized CH formula for patients with advanced lung cancer. The secondary objective was to identify any toxicities attributable to this CH formula and to measure changes in quality of life. METHODS A single-arm, prospective study of a 6-week intervention with a selected CH formula in 15 patients with stage 4 nonsmall-cell lung cancer (NSCLC, Seventh American Joint Committee on Cancer TNM staging system). RESULTS Patients with advanced lung cancer were interested in using the CH formula. Completion (93%) and adherence (98%) levels were very high and most patients perceived the CH treatment as easy to take and were willing to take the CHs used in the study again if it was available. About half of the patients reported adverse events, all of which were mild (Grade 1 or 2) and only a small minority (8%) were potentially related to CHs. No biochemical or hematological evidence of toxicity was observed. Overall, there were improvement in quality of life, and reduced feelings of tiredness and sleepiness. CONCLUSION This study provides preliminary evidence that short-term use of a carefully selected and prepared CH formula in patients with stage 4 NSCLC is acceptable and safe.

Ovatodiolide suppresses yes-associated protein 1-modulated cancer stem cell phenotypes in highly malignant hepatocellular carcinoma and sensitizes cancer cells to chemotherapy in vitro. Toxicol In Vitro 2018; 51:74-82. [PMID: 29698666 DOI: 10.1016/j.tiv.2018.04.010] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/13/2017] [Revised: 04/09/2018] [Accepted: 04/22/2018] [Indexed: 02/06/2023]
Abstract
The cancer stem cells (CSCs) theory recently became a focus of heightened attention in cancer biology, with the proposition that CSCs may constitute an important therapeutic target for effective anticancer therapy, because of their demonstrated role in tumor initiation, chemo-, and radio-resistance. Liver CSCs are a small subpopulation of poorly- or undifferentiated liver tumor cells, implicated in tumorigenesis, metastasis, resistance to therapy and disease relapse, enriched with and associated with the functional markers corresponding to the CSCs-enriched side population (SP), high aldehyde dehydrogenase (ALDH) activity, and enhanced formation of in vitro liver CSCs models, referred to herein as hepatospheres. In this study, we found YAP1 was significantly expressed in the SP cells, as well as in generated hepatospheres compared to non-SP or parental HCC cells, at transcript and/or protein levels. In addition, downregulation of YAP1 expression levels by small molecule inhibitor and siRNA transfection, in the HCC cell lines, PLC/PRF/5 and Mahlavu, were associated with marked loss of ability to form hepatospheres and increased sensitivity to sorafenib. Consistent with the above, we demonstrated that YAP1 expression positively correlated with that of Sox2, Oct4, c-Myc and GRP78, markers of stemness and drug resistance. This is suggestive of YAP1's role as a modulator of cancer stemness, ER stress and chemoresistance. For the first time, we demonstrate that Ovatodiolide significantly attenuates YAP1 expression and subsequently suppressed YAP1-modulated CSCs phenotypes and associated disease progression, consistent with our previous finding in breast cancer. Taken together, our findings suggest that YAP1, highly expressed in malignant liver tumours, contributes to hepatocellular CSCs phenotype and is a molecular target of interest for CSCs targeted therapy in liver cancer patients.

Abstract
Metastasis of cancer is the cause of the majority of cancer deaths. Active compound flaccidoxide-13-acetate, isolated from the soft coral Cladiella kashmani, has been found to exhibit anti-tumor activity. In this study, Boyden chamber analysis, Western blotting and gelatin zymography assays indicated that flaccidoxide-13-acetate exerted inhibitory effects on the migration and invasion of RT4 and T24 human bladder cancer cells. The results demonstrated that flaccidoxide-13-acetate, in a concentration-dependent manner, reduced the levels of matrix metalloproteinase-2 (MMP-2), MMP-9, urokinase-type plasminogen activator receptor (uPAR), focal adhesion kinase (FAK), phosphatidylinositide-3 kinases (PI3K), p-PI3K, AKT, p-AKT, mammalian target of rapamycin (mTOR), p-mTOR, Ras homolog gene family, member A (Rho A), Ras, mitogen-activated protein kinase kinase 7 (MKK7) and mitogen-activated protein kinase kinase kinase 3 (MEKK3), and increased the expressions of tissue inhibitor of metalloproteinase-1 (TIMP-1) and TIMP-2 in RT4 and T24 cells. This study revealed that flaccidoxide-13-acetate suppressed cell migration and invasion by reducing the expressions of MMP-2 and MMP-9, regulated by the FAK/PI3K/AKT/mTOR pathway. In conclusion, our study was the first to demonstrate that flaccidoxide-13-acetate could be a potent medical agent for use in controlling the migration and invasion of bladder cancer.

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.

Ovatodiolide of Anisomeles indica Exerts the Anticancer Potential on Pancreatic Cancer Cell Lines through STAT3 and NF-κB Regulation. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2016; 2016:8680372.

Abstract
Pancreatic cancer is the eighth leading cause of cancer death worldwide. Patients with pancreatic cancer are normally diagnosed at an advanced stage and present poor survival rate. Ovatodiolide (OV), a bioactive macrocyclic diterpenoid isolated from Anisomeles indica, showed cytotoxicity effects in pancreatic cancer cells by inhibiting cell proliferation and inducing apoptosis. Moreover, not only were cell adhesion and invasion markedly suppressed in a dose-dependent manner, but the mRNA expression of matrix metalloproteinase-9 (MMP-9) and focal adhesion kinase (FAK) was also significantly decreased. Western blot analysis indicated that OV potently suppressed the phosphorylation of STAT-3 and its upstream kinase including ERK1/2, P38, and AKT Ser473. Meanwhile, OV inactivated the nuclear factor kappa B (NF-κB) by inhibiting IκB kinase (IKK α/β) activation and the subsequent suppression of inhibitor of kappa B (IκB) phosphorylation. These results demonstrated that OV could potentially inhibit Mia-PaCa2 cancer cells proliferation and induce apoptosis through modulation of NF-κB and STAT3 pathway. Moreover, OV suppressed cell invasiveness and interfered with cell-matrix adhesion in Mia-PaCa2 cancer cells by reducing MMP-9 and FAK transcription through suppressing NF-κB and STAT3 pathway. Taken together, our findings reveal a new therapeutic and antimetastatic potential of ovatodiolide for pancreatic cancer remedy.

Abstract
The whole plant of Anisomeles ovata has been widely used in Taiwan for treating inflammation-related skin and liver diseases, however, the detailed pharmacology mechanisms have yet to be elucidated. In the present study, one of the major components, 5,6,4'-trihydroxy-7,3'-dimethoxyflavone (5-TDMF), was purified from a methanol extract of Anisomeles ovata. A pharmacological study of this compound suggests that 5-TDMF possesses potent free radical scavenging activity both in vitro and ex vivo. Furthermore, 5-TDMF reduces nitric oxide and pro-inflammatory cytokine production in LPC-treated RAW 264.7 cells through the attenuation of nitric oxide synthase and cyclooxygenase-2. Additional experiments suggest that of 5-TDMF interferes with nuclear factor-κB translocation and mitogen-activated protein kinase pathways. These results identify 5-TDMF as an anti-oxidant and anti-inflammatory compound, explain the pharmacologic function of Anisomeles ovata and suggest its great potential as a new anti-inflammatory remedy.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Tharu community is the largest primitive indigenous community of the Uttarakhand, India. In this article we have scientifically enumerated medicinal plants and herbal preparations used by the Tharu community to treat various skin diseases, and discussed dermatological properties of these plants in the light of previous ethnomedicinal, microbiological, pharmacological, toxicological, phytochemical and clinical studies. MATERIALS AND METHODS Ethnomedicinal survey was conducted in different villages of Tharu community located in district Udham Singh Nagar, Uttarakhand, India. Ethnomedicinal information on plants used to treat various skin diseases was collected from 122 individuals (93 males and 29 females), including 35 experienced herbal practitioners and 87 local villagers. For each of the recorded plant species the use value (UV) and fidelity level (FL) was calculated. The informant consensus factor (Fic) was also calculated to find out the homogeneity in the information given by the informants. RESULTS A total of 90 plant species belonging to 86 genera and 48 families were used by the Tharu community to treat various skin diseases viz., wounds (38 spp.), boils (32 spp.), cuts (18 spp.), leprosy (11 spp.), eczema (10 spp.), itching (7 spp.), ringworm (5 spp.), burns (4 spp.), leucoderma (4 spp.), cracked heels (2 spp.), dandruff (3 spp.), body infection (2 spp.), chilblains (2 spp.), hair fall (2 spp.) and toes infection (2 spp.). Information on botanical name, family, vernacular name, ailments treated, mode and dose of herbal preparations, UV and FL values are provided for each of the recorded species. According to UV value most preferred plant species used to treat skin diseases by Tharu community was Ricinus communis L. followed by Tridax procumbens (L.) L., Azadirachta indica A. Juss., Ageratum conyzoides and Allium cepa L. CONCLUSIONS The present study has revealed significant information on various medicinal plants used to treat skin diseases by Tharu community. Literature review has confirmed most of the claims made by the Tharu community regarding treatment of various skin diseases by the reported plants. The literature review has also revealed that products from very few of the reported plants are available in market, while most of the reported plants are still under preclinical or clinical trials. There are various known phytochemicals, and antibiotic, antibacterial, antiviral and antifungal agents present in these plants which may be synthesized or transformed to make pharmaceuticals. Some of the reported plants have shown promising results in preclinical trails and there is a need of clinical trials to see their safety and efficacy in treating various skin diseases. These plants may be targeted for development of new medicines, ointments or drugs for the treatment of skin diseases. However further toxicological, preclinical and clinical studies are needed to validate claims about little worked out plant species reported in the present study viz., Sida cordata (Burm. F.) Borss. Waalk., Millettia extensa (Benth.) Baker, Caesulia axillaris Roxb., Ehretia laevis Roxb., Vanda tessellate (Roxb.) Hook. Ex G.Don. and Eualaliopsis binata (Retz.) C.E. Hubb. Further studies on these plants are recommended to assess their potential in development of new skin care products.

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
Objectives: To find the efficacy of serial extracts of Anisomeles malabarica in inhibiting proliferation of and inducing apoptosis in human cervical cancer cells, SiHa and ME 180, that are HPV 16-positive. Materials and Methods: The whole plant was extracted in n-hexane, chloroform, ethyl acetate, n-butanol, methanol, and water. The cells were treated with the extracts at increasing concentrations to find the IC50, adopting MTT ([3-(4,5 dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide]) assay. Acridine orange (AO) and ethidium bromide (EB) and Hoechst 33258 staining were adopted to assess the mode of cell death, Annexin V-Cy3 staining to evaluate one of the early apoptotic features, JC-1 staining to assess the mitochondrial membrane depolarization, comet assay for DNA fragmentation, and cell cycle analysis for the distribution of cells after treatment. Results: n-Hexane and chloroform extracts were cytotoxic to the cervical cancer cells in dose- and duration-dependent manner. The cells that responded to the treatments revealed typical apoptotic features. Early features of apoptosis, phosphatidyl serine translocation and loss of mitochondrial trans-membrane potential, were observed in the treated cells, and comet assay revealed DNA damage. In the FACS analysis, the cells accumulated in the sub-G0/G1 phase of the cell cycle, except in n-hexane- and chloroform extract–treated SiHa cells at 24 h, which showed arrest in S- and G2/M phases. Conclusions: n-Hexane and chloroform extracts of A. malabarica inhibit proliferation of and induce death in HPV16-positive cervical cancer cells, mostly by apoptosis and to some extent by necrosis.

Abstract
Anisomeles indica popularly known in Taiwan as 'yu-chen-tsao' has been traditionally used as an anticancer and anti-inflammatory agent; however, little is known about its anti-metastatic potential. Therefore, we attempted in this study to examine the anti-metastatic potential of A. indica aqueous extract (AI), its isolated compounds apigenin, ovatodiolide, β-sitosterol and acteoside in 12-O-tetradecanoylphorbol-13-acetate (TPA)-induced human breast adenocarcinoma MCF-7 cells. Among the test agents, crude extract AI and pure compound apigenin potently suppressed the TPA-induced MCF-7 cells migration and invasion. In addition, AI and apigenin time- and dose-dependently down regulated the matrix metalloproteinase (MMP)-9 enzymatic activities and its mRNA expression. Furthermore, AI and apigenin also down regulated the nuclear factor (NF)-κB subunit p65, and activator protein (AP)-1 subunit c-Fos proteins expression in nucleus and, transcriptional activity of NF-κB and AP-1. This is the first report on the anti-metastatic potential of A. indica that suppressed the cancer cell invasion through the inhibition of MMP-9 enzyme via NF-κB/AP-1 signaling. Taken together, our data indicate that A. indica can be considered as a source of new anti-metastatic agent for food and pharmaceutical industries.

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.

Abstract
Cancer metastasis is a primary cause of cancer death. Ovatodiolide, a bioactive cembrane-type diterpenoid isolated from Anisomeles indica (L.) Kuntze (Labiatae), has been shown to inhibit the growth and proliferation of cancer cells. However, the anti-metastatic effects of ovatodiolide on highly metastatic human breast cancer MDA-MB-231 cells remain unclear. In this study, we first noted that ovatodiolide inhibited MDA-MB-231 cell migration and invasion by wound-healing assay and Boyden chamber assay. Western blot, gelatin zymography and reversed transcription-PCR analysis showed that ovatodiolide significantly and selectively suppressed the expression, activation, and mRNA of matrix metalloproteinase-9 (MMP-9) in a concentration-dependent manner. Ovatodiolide significantly decreased the nuclear level of nuclear factor kappaB (NF-κB), increased inhibitor of kappaBα (IκBα) through preventing phosphorylation of upstream signal IκB kinase (IKK). Pretreatment with a specific NF-κB inhibitor (PDTC) and an IκB protease inhibitor (TPCK) also reduced MMP-9 activity, cell migration and cell invasion. Moreover, ovatodiolide can suppress activation of c-Jun N-terminal kinase, p38 mitogen-activated protein kinase, phosphatidylinositol 3-kinase and Akt, while it did not affect phosphorylation of extracellular signal regulating kinases (ERK)1/2. Additionally, the treatment of inhibitors specific for PI3K (wortmannin), JNK (SP600125) or p38 MAPK (SB203580) to MDA-MB-231 cells could result in a reduced activation of MMP-9, concomitantly with a marked inhibition on cell migration and invasion. Taken together, these results demonstrate that ovatodiolide inhibits the metastatic ability of MDA-MB-231 cells by reducing MMP-9 activity through suppressing JNK, p38 MAPK and PI3K/Akt signaling pathways and inhibiting NF-κB activity. These results are the first to reveal the function of ovatodiolide in tumor metastasis and its underlying molecular mechanism, thus suggesting ovatodiolide to be a promising antimetastatic agent.
