Agarwood is the fragrant resinous heartwood obtained from certain trees in the genus Aquilaria belonging to the family Thymelaeaceae. 2-(2-Phenylethyl)chromones and characteristic sesquiterpenes are the main classes of aromatic compounds isolated from agarwood. Although there are many sesquiterpenes, relatively few 2-(2-phenylethyl)chromones have been determined in agarwood by GC-MS. After anal...
Glutathione plays an important role in the protection of the liver against several hepatotoxins. The hepatocarcinogen N-hydroxy-2-acetylaminofluorene is converted in the rat in vivo to reactive metabolites that bind covalently to cellular macromolecules. These metabolites may also react with glutathione, resulting in the formation of glutathione conjugates and in the detoxification of reactive ...
In this communication we report on the base catalyzed Michael addition of the hydroxy methyl side groups in polyglycidol to diethyl vinyl phosphonate. Hydrolysis of the diethyl phosphonato ethyl side groups with bromotrimethylsilane leads to a new class of polyglycidols with pendant phosphonic acid groups.
BACKGROUND/AIM Vascular endothelial growth factor (VEGF) is associated with various ischemic and inflammatory diseases, and plays an important role in the development of liver fibrosis and hepatocarcinogenesis in nonalcoholic steatohepatitis (NASH). In this study, the comparative effect of pioglitazone, quercetin, and hydroxy citric acid on VEGF mRNA in experimentally induced NASH was investiga...
