Metabolism of Debrisoquine Sulphate in Rat, Dog and Man

Abstract

1. The metabolism of debrisoquine sulphate in the dog has been studied and is similar to that in rat and man. 2. Two acidic urinary metabolites, shown to be present in rat, dog and man, have been isolated from rat urine. After derivatization they were characterized by n.m.r. and mass spectroscopy as methyl 2-[2-(4,6-dimethylpyrimidylamino)-methyl]-phenylacetate and 2-[2-(4,6-dimethylpyrimidylamino)-ethyl]benzoate.
