The influence of psychotropic drugs on aldole, mitochondrial malic dehydrogenase and Mg++na+K+ adenosine triphosphatase.

1. The experiment investigated the effects of psychotropic drugs on enzymes in vitro.2. Chlorpromazine inhibits mitochondrial malate dehydrogenase in concentrations of 1.4x10(-4)M and above. No effect was observed below this concentration.3. A sharp inflection in the [unk]/drug plot was also seen with chlorpromazine (1.4 x 10(-4)M), trifluoperazine (1 x 10(-5)M), prochlorperazine (1 x 10(-4)M), and amylobarbitone (8 x 10(-3)M) acting on rat brain (Na(+)-K(+)-) Mg(++)-ATPase and with chlorpromazine (10(-4)M) and imipramine (3 x 10(-4)M) acting on aldolase.
