[Enzymatic N-acetylation of tryptamine by brain homogenates of Locusta migratoria before and after intoxication by chlordimeform or lindane (author's transl)].

Brain homogenates of Locusta migratoria are found to possess enzyme capable of catalyzing the N-acetylation of tryptamine. A main product of the enzymatic reaction is isolated and identified as N-acetyltryptamine by chromatography analyse. Both insecticides, chlordimeform and lindane, inhibit enzyme activity. A direct correlation between the degree of intoxication and acetylation of tryptamine is described.
