PG - 191-9 AB - The in vivo and in vitro effects of various monoamine oxidase inhibitors (MAOI) on the borohydride stabilizable finding of serotonin (5-HT) or tryptamine in brain was investigated. A significant correlation between the extent of Mao inhibition and the amount of stabilized binding of the indolealkylamines was demonstrated. All hydrazine-type MAOI and harmine, a reversible nonhydrazine-type MAOI, employed in vitro, were shown to decrease the binding. beta-Phenylisopropylhydrazine apparently blocks the receptor carbonyl groups in the brain in vitro as well as in vivo.
