摘要: Abstract Rats receiving approx. 2.5 mg kg of phenelzine-1-14C by the intraperitoneal route were placed in metabolism cages and their urine collected for 24 hr. Phenylacetic-1-14C acid was recovered as a major metabolite. Pretreatment animals with tranylcypromine (10 ) or pargyline (100 prior to injection radioactive phenelzine markedly reduced urinary excretion phenylacetic-1-14C other unidentified metabolites appeared increase. Inhibition monoamine oxidase (MAO) had no effect on an equimolar dose administered same route. Therefore, pretreatment rats appears have decreased bioconversion injected phenylacetic acid. These results provide further evidence that phenelzine, addition being irreversible inhibitor, is also substrate MAO intact animal.
