Abstract
Thirty compounds including 13 new phenolic glycosides (1-6, 9-15) and 17 known aromatic compounds and aromatic glycosides (7-8, 16-30) were isolated from the roots of Wrightia pubescens. The structures of the new phenolic glycosides were established by extensive NMR spectroscopic data analysis as well as chemical derivatization method. The isolated compounds were evaluated for their hepatoprotective activities using cell model of acetaminophen (APAP)-induced HepG2 cells. The results indicated that phenolic glycosides (2, 4, 5, 7, 8, 11, 13) pretreatment enhanced the cells viability and reduced the levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT). The hepatoprotective mechanism of a representative new compound, wrightioside D (4), was further investigated. Compound 4 exhibited hepatoprotective effects via reducing oxidative stress by attenuating ROS formation and inhibiting apoptosis in APAP-treated HepG2 cells.
期刊介绍:
The Journal of Natural Products invites and publishes papers that make substantial and scholarly contributions to the area of natural products research. Contributions may relate to the chemistry and/or biochemistry of naturally occurring compounds or the biology of living systems from which they are obtained.
Specifically, there may be articles that describe secondary metabolites of microorganisms, including antibiotics and mycotoxins; physiologically active compounds from terrestrial and marine plants and animals; biochemical studies, including biosynthesis and microbiological transformations; fermentation and plant tissue culture; the isolation, structure elucidation, and chemical synthesis of novel compounds from nature; and the pharmacology of compounds of natural origin.
When new compounds are reported, manuscripts describing their biological activity are much preferred.
