title: [Biotransformation of 4-oxa-5-exo-(N-methylcarbamoyloxy)-tricyclo-[5.2.1.0-2, 6endo] dec-8-en-3one in the rat].
abstract: The metabolism of the analgesic compound 4-oxa-5-exo-(N-methylcarbamoyloxy)-tricyclo-[5.2.1.0-2. 6endo]dec-8-en-3one (Lu 253) was investigated after oral application in male Wistar rats. From urine, faeces, bile, and plasma epoxidized, rearranged, and N-desmethylated metabolites were isolated. The main reaction was the epoxidation of the double bond. The structure of most of the biotransformation products was proved by synthetic compounds.
