Soluble Epoxide Hydrolase Inhibitory Activity of Components Isolated from Apios americana Medik.
A new compound 1, 5-methoxy-2,5,7,4'-tetrahydroxy-coumaronochromone, along with seven known compounds (2-8), were isolated from Apios americana using open column chromatography. Their structures were established based on an analysis of 1D and 2D NMR, and MS spectra. Among these, two compounds 1 and 2 showed inhibitory activity on soluble epoxide hydrolase (sEH) at a concentration below 50 μM. T...
متن کاملMeasurement of soluble epoxide hydrolase (sEH) activity.
The human soluble epoxide hydrolase (sEH; EC 3.3.3.2) is the product of the EXPH2 gene. The sEH catalyzes the addition of a water molecule to an epoxide, resulting in the corresponding diol. Early work suggested a role of sEH in detoxifying a wide array of xenobiotic epoxides; however, recent findings clearly implicate the sEH in the regulation of blood pressure, pain, and inflammation through ...
متن کاملSoluble Epoxide Hydrolase Inhibitory Activity of Selaginellin Derivatives from Selaginella tamariscina.
Selaginellin derivatives 1-3 isolated from Selaginella tamariscina were evaluated for their inhibition of soluble epoxide hydrolase (sEH) to demonstrate their potential for the treatment of cardiovascular disease. All selaginellin derivatives (1-3) inhibited sEH enzymatic activity and PHOME hydrolysis, in a dose-dependent manner, with IC50 values of 3.1 ± 0.1, 8.2 ± 2.2, and 4.2 ± 0.2 μM, respe...
متن کاملSoluble epoxide hydrolase in rat inflammatory cells is indistinguishable from soluble epoxide hydrolase in rat liver.
Soluble epoxide hydrolase (sEH) is a ubiquitous mammalian enzyme for which liver and kidney are reported to have the highest activity. We have shown that the soluble epoxide hydrolase (sEH) activity present in rat neutrophils and macrophages is kinetically, immunologically, and physically indistinguishable from rat liver cytosolic sEH. Cytosol from rat liver or inflammatory cells and recombinan...
متن کاملChemical Constituents from Apios americana and Their Inhibitory Activity on Tyrosinase.
The goal of this study was to identify phytochemicals with inhibitory activity against tyrosinase. Nine compounds 1-9 were isolated from the tubers of Apios americana. This is the first report of aromadendrin 5-methyl ether (1) being isolated from the Apios species. Among them, compounds 2 and 8 showed inhibitory activity toward tyrosinase. Based on a Dixon plot, the potential Ki values of comp...
