Mice were injected with single doses of MPTP (15 mg/kg, s.c.) containing one u̧Ci of [3H]methyl-MPTP. Approximately 42% of the total injected [3H] was detected in the urine within 3 hours after drug administration. The early urine samples were analyzed using high pressure liquid chromatography. MPTP N-oxide was identified as a major metabolite, with trace amounts of MPP+and MPTP also detected. The urinary volume and excretion of MPTP metabolites were inhibited by pretreating the animals with probenecid (250 mg/kg, i.p.). These results indicate that large amounts of injected MPTP are rapidly metabolized in the periphery by liver enzymes to form MPTP N-oxide.
