The role of monamine oxidase (MAO), type A and B, on the deamination of dopamine in the striatum, nucleus accumbens and frontal cortex of the rat was studied. Levels of dopamine, 3,4-dihydroxyphenylacetic acid (DOPAC) and homovanillic acid (HVA) tissue were quantified by means of high pressure liquid chromatography with electrochemical detection. Rats were given pargyline (75 mg/kg), selegyline (5 mg/kg) or clorgyline (2 mg/kg) by the intraperitoneal route, 60 min before sacrifice; in another set of experiments, clorgyline (2 mg/kg, i.p.) was given 15 or 30 min before sacrifice. Only clorgyline and pargyline were found to reduce significantly the formation of DOPAC and HVA in all the three areas of brain under study (83-97% reduction). The inhibition of deamination of dopamine by clorgyline and pargyline was accompanied by an increase in levels of dopamine in tissue. The increase of the levels of amine in tissue, as a result of inhibition of MAOA was more marked in the frontal cortex (52% increase) and the accumbens (39% increase), than in the striatum (25% increase). The results suggest that a substantial amount of DOPAC in brain derives from the deamination of dopamine by MAOA.
