Abstract
The metabolism and catabolism of a novel antineoplastic (ID code JS-38),Benzamide, N-[4-(2,4-dimethoxyphenyl)-4,5-dihydro-5-oxo-1,2-dithiolo[4,3-b]pyrrol-6-yl]-3,5-bis (trifluoromethyl)-(9Cl), were investigated in Wistar rats (3 female, 3 male). LC/UV, LC/MS, LC/MS/MS, NMR and acid hydrolysis methods showed that the metabolic process of JS-38 consists of a series of acetylation and glucoronation that form a metabolic product with a unique pharmacologic property of accelerating bone-marrow cell formation, and also showed a novel metabolic pathway of being acetylated and glucuronated in series.
