Histone Deacetylase Inhibitory and Cytotoxic Activities of the Constituents from the Roots of Sophora Pachycarpa.

ABSTRACT: Four prenylated flavonoids, including isosophoranone, sophoraflavanone G, alopecurone J, alopecurone P, and a resveratrol derivative HPD (2-(4-hydroxyphenyl)-2,3-dihydrobenzo[b] furan-3,4,6-triol), were isolated from the roots of Sophora pachycarpa. The cytotoxic activity of obtained compounds was evaluated against A2780, A549, HeLa, and HCT116 human cancer cell lines. We also evaluated their histone deacetylase (HDAC) inhibitory activities. Of all compounds tested, alopecurone J was the most active with IC₅₀ values in the range of 9.97-30.91 μM against four cancer cell lines with potent pan-HDAC inhibitory activity (IC₅₀ = 0.08-3.85 μM). Molecular docking experiments of these compounds with HDAC8 displayed potential selective HDAC inhibitory. Molecular docking data showed consistent results in the in-vitro experiments with high selectivity towards HDAC8. The Resveratrol group plays an essential role in HDAC inhibition.

Chemical Constituents from Roots of Sophora davidii (Franch.) Skeels and Their Glucose Transporter 4 Translocation Activities.

Project description:Sophora davidii (Franch.) Skeels is a multi-purpose traditional medicine that has long been used for the treatment of various diseases. To discover the potential bioactive composition of S. davidii, a chemical investigation was thus performed. In this research, two new stilbene oligomers, Davidiol E-F (1-2), one new 4-aryl-substituted isoflavan Davidinin A (3), and one new 2-arylbenzofuran dimer, Shandougenine C (4), as well as six known compounds (5-10) were obtained from the ethyl acetate fraction of Sophora davidii (Franch.) Skeels. The structures of new compounds were established by extensive 1D and 2D nuclear magnetic resonance (NMR) spectra with mass spectroscopy data. The absolute configuration of 1-3 was assigned by comparing its experimental and calculated electronic circular dichroism (ECD) spectra. Compounds 1-10 promoted glucose transporter 4 (GLUT-4) translocations by the range of 1.28-2.60 folds, respectively. Compound 9 showed the most potent glucose transporter 4 translocations with 1.60 fold enhancement. The result attained in this study indicated that the separation and characterization of these compounds plays an important role in the research and development of new anti-diabetic drugs and pharmaceutical industry.

Four New Anthraquinones with Histone Deacetylase Inhibitory Activity from Ventilago denticulata Roots.

Project description:Chromatographic separation of the crude extracts from the roots of Ventilago denticulata led to the isolation of four new anthraquinones, ventilanones L-O (1-4), together with eight known anthraquinones (5-12). Their structures were elucidated by spectroscopic methods (UV, IR, 1H NMR, 13C NMR, and 2D NMR) and mass spectrometry (MS), as well as comparison of their spectroscopic data with those reported in the literature. HDACs inhibitory activity evaluation resulted that compound 2 exhibited moderate antiproliferative activity against HeLa and A549 cell lines but nontoxic to normal cell. Molecular docking indicated the phenolic functionality of 2 plays crucial interactions with class II HDAC4 enzyme.

Thailandepsins: bacterial products with potent histone deacetylase inhibitory activities and broad-spectrum antiproliferative activities.

Project description:Histone deacetylase (HDAC) inhibitors have emerged as a new class of anticancer drugs, with one synthetic compound, SAHA (vorinostat, Zolinza; 1), and one natural product, FK228 (depsipeptide, romidepsin, Istodax; 2), approved by FDA for clinical use. Our studies of FK228 biosynthesis in Chromobacterium violaceum no. 968 led to the identification of a cryptic biosynthetic gene cluster in the genome of Burkholderia thailandensis E264. Genome mining and genetic manipulation of this gene cluster further led to the discovery of two new products, thailandepsin A (6) and thailandepsin B (7). HDAC inhibition assays showed that thailandepsins have selective inhibition profiles different from that of FK228, with comparable inhibitory activities to those of FK228 toward human HDAC1, HDAC2, HDAC3, HDAC6, HDAC7, and HDAC9 but weaker inhibitory activities than FK228 toward HDAC4 and HDAC8, the latter of which could be beneficial. NCI-60 anticancer screening assays showed that thailandepsins possess broad-spectrum antiproliferative activities with GI50 for over 90% of the tested cell lines at low nanomolar concentrations and potent cytotoxic activities toward certain types of cell lines, particularly for those derived from colon, melanoma, ovarian, and renal cancers. Thailandepsins thus represent new naturally produced HDAC inhibitors that are promising for anticancer drug development.

Constituents of the roots and leaves of Ekebergia capensis and their potential antiplasmodial and cytotoxic activities.

Project description:A new triterpenoid, 3-oxo-12β-hydroxy-oleanan-28,13β-olide (1), and six known triterpenoids 2-7 were isolated from the root bark of Ekebergia capensis, an African medicinal plant. A limonoid 8 and two glycoflavonoids 9-10 were found in its leaves. The metabolites were identified by NMR and MS analyses, and their cytotoxicity was evaluated against the mammalian African monkey kidney (vero), mouse breast cancer (4T1), human larynx carcinoma (HEp2) and human breast cancer (MDA-MB-231) cell lines. Out of the isolates, oleanonic acid (2) showed the highest cytotoxicity, i.e., IC50's of 1.4 and 13.3 µM against the HEp2 and 4T1 cells, respectively. Motivated by the higher cytotoxicity of the crude bark extract as compared to the isolates, the interactions of oleanonic acid (2) with five triterpenoids 3-7 were evaluated on vero cells. In an antiplasmodial assay, seven of the metabolites were observed to possess moderate activity against the D6 and W2 strains of P. falciparum (IC50 27.1-97.1 µM), however with a low selectivity index (IC50(vero)/IC50(P. falciparum-D6)<10). The observed moderate antiplasmodial activity may be due to general cytotoxicity of the isolated triterpenoids.

Protective effect of Sophora pachycarpa seed extract on carbon tetrachloride-induced toxicity in rats.

Project description:The aim of the present study was to investigate the protective effect of the Sophora pachycarpa (S. pachycarpa) seed extract against carbon tetrachloride-induced toxicity on body organs, blood, and biochemical factors. In this investigation, 40 male Wistar rats weighing 200-250 g were randomly divided into 5 groups: group I was used as control, group II received carbon tetrachloride (CCl4) (IP, 1 mL/kg) on day 21, group III and group IV received S. pachycarpa seed extract at doses of 150 mg/kg and 300 mg/kg, respectively for 21 days by oral gavage and CCl4 on day 21, group V received silymarin (300 mg/kg) for 21 days by oral gavage and CCl4 on day 21. CCl4 showed an increase of serum renal and hepatic markers creatinine, urea, blood urea nitrogen (BUN), and uric acid, alkaline phosphatase (ALP), aspartate aminotransferase (AST), and alanine aminotransferase (ALT). Also, it significantly increased MDA level, and decreased CAT, FRAP, GSH, and SOD in the liver and kidney tissues. These changes and also hematological and histopathological alterations were significantly ameliorated by S. pachycarpa seed extract before CCl4 administration. In conclusion, the data obtained in our investigation confirm the protective effect of S. pachycarpa against acute exposure to CCl4-induced organ toxicity in rats.

Chemical constituents of industrial hemp roots and their anti-inflammatory activities.

Project description:ObjectiveAlthough the chemical constituents of the aerial parts of Cannabis have been extensively studied, phytochemicals of Cannabis roots are not well characterized. Herein, we investigated the chemical constituents of industrial hemp (Cannabis sativa L.) roots and evaluated the anti-inflammatory activities of phytochemicals isolated from the hemp roots extract.MethodsAn ethyl acetate extract of hemp roots was subjected to a combination of chromatographic columns to isolate phytochemicals. The chemical structures of the isolates were elucidated based on spectroscopic analyses (by nuclear magnetic resonance and mass spectrometry). The anti-inflammatory effects of phytochemicals from hemp roots were evaluated in an anti-inflammasome assay using human monocyte THP-1 cells.ResultsPhytochemical investigation of hemp roots extract led to the identification of 32 structurally diverse compounds including six cannabinoids (1-6), three phytosterols (26-28), four triterpenoids (22-25), five lignans (17-21), and 10 hydroxyl contained compounds (7-16), three fatty acids (29-31), and an unsaturated chain hydrocarbon (32). Compounds 14-21, 23, 27, and 32 were identified from the Cannabis species for the first time. Cannabinoids (1-5) reduced the level of cytokine tumor necrosis-alpha (by 38.2, 58.4, 47.7, 52.2, and 56.1%, respectively) and 2 and 5 also decreased the interleukin-1β production (by 42.2 and 92.4%, respectively) in a cell-based inflammasome model. In addition, non-cannabinoids including 11, 13, 20, 25, 29, and 32 also showed selective inhibition of interleukin-1β production (by 23.7, 22.5, 25.6, 78.0, 24.1, 46.6, and 25.4%, respectively) in THP-1 cells.ConclusionThe phytochemical constituent of a hemp roots extract was characterized and compounds from hemp roots exerted promising anti-inflammatory effects.

Two New Isoprenoid Flavonoids from <i>Sophora flavescens</i> with Antioxidant and Cytotoxic Activities.

Project description:Sophora flavescens is a regularly used traditional Chinese medicine. In an attempt to discover adequate active agents, the isoprenoid flavonoids from S. flavescens were further investigated. In this work, two new compounds (1-2, kurarinol A-B) together with 26 known ones (3-28) were isolated and elucidated on the basis of extensive NMR, UV and MS analyses. Furthermore, the antioxidant activity of all constituents was assessed through ABTS, PTIO and DPPH methodologies and also were evaluated for cytotoxic activity by three tumor cell lines (HepG2, A549 and MCF7) and one human normal cell line (LO2 cells). As a result, a multitude of components revealed significant inhibitory activity. In particular, compound 1-2 (kurarinol A-B), two new flavanonols derivatives, exhibited the most potent ABTS inhibitory activity with IC50 of 1.21 µg/mL and 1.81 µg/mL, respectively. Meanwhile, the new compound 1 demonstrated remarkable cytotoxicity against three cancer cells lines with IC50 values ranging from 7.50-10.55 μM but showed little effect on the normal cell. The two new isoprenoid flavonoids could be promising antioxidant and anti-tumor nature agents.
