UK-383,367(5-{(1R)-4-cyclohexyl-1-[2-(hydroxyamino)-2-oxoethyl]butyl}-1,2,4-oxadiazole-3- carboxamide) is a novel procollagen C-proteinase inhibitor evaluated for the treatment of post-surgical dermal scarring. It is extensively metabolized in rat and dog absorption, distribution, metabolism and excretion studies, and a metabolic pathway for UK- 383,367 was determined. A long-lived metabolite was identified in dog plasma. Data indicate that this metabolite results from the oxadiazole ring-cleavage- producing oxamic acid, oxamide and oxalic acid. Ion exclusion chromatography was used to identify these polar metabolites, which were unretained on a standard reversed-phase high-performance liquid chromatography system. The oxamide metabolite was identified as the long-lived radioactivity, which was observed in dog plasma.
