Three major urinary metabolites of sinomenine in rats.
Urinary metabolites of sinomenine were investigated in rats after intragastric administration. Three major metabolites were obtained and characterised as 4-hydroxy-3,7,7-trimethoxy-17-methyl-(9alpha,13alpha,14alpha)-morphinan-6-one (1), 7,8-didehydro-4-hydroxy-3,7-dimethoxy-17-methyl-N-oxide-(9alpha,13alpha,14alpha)-morphinan-6-one (2), and 7,8-didehydro-4-hydroxy-3,7-dimethoxy-(9alpha,13alpha,14alpha)-morphinan-6-one (3). Their structures have been elucidated on the base of spectral analysis, among which 1 and 2 were new compounds.
