Metabolism of DL-[14C]prenylamine in man. 1977

G Remberg, and M Eichelbaum, and G Spiteller, and H J Dengler

Following oral administration of DL-[14C]prenylamine, about 40% of the dose administered was excreted in urine within 10 days. Less than 0.1% of the dose was excreted as unchanged prenylamine. The drug was extensively metabolized to at least 20 to 25 metabolites. The structure of 12 metabolites could be elucidated by means of g.c.m.s. Ring hydroxylation and further methylation of the phenolic metabolites are the main metabolic pathways involved. A substantial part of the drug and/or its metabolites is metabolized via cleavage of the C--N--C bond, giving rise to amphetamine and diphenylpropylamine which are further metabolized by aromatic and sidechain hydroxylation.
