Abstract

2-Methylaminoethyl-4, 4'-dimethoxy-5, 5', 6.6 -dimethylenedioxybiphenyl-2'-carboxy-2-carboxylate (DDB-S), a synthetic compound derived from DDB, has been known to protect liver against carbon tetrachloride-, D-galactosamine-, thioacetamide-, and prednisolone-induced hepatic injury in experimental animals. The metabolism of this compound has been assessed in rats by using liquid chromatography/electrospray tandem mass spectrometry (LC/MS/MS) method. (omitted)
