Abstract

The structure-activity relationships (SAR) of various known hallucinogenic and nonhallucinogenic indolealkylamine and phenethylamine derivatives were compared on two different behaviors: mouse locomotor activity and acquisition of one-way avoidance behavior in the rat. Certain parallels were observed between the two classes of compounds. α-Methyl substituted derivatives of the indoles and phenethylamines increased dramatically psychomotor stimulant effects. Acquisition of one-way avoidance behavior was reduced by the more potent hallucinogens and psychomotor stimulants of both classes. Pargyline pretreatment enhanced the psychomotor stimulant effects of all of the compounds tested except 5-hydroxy-tryptamine (5-HT), d-amphetamine, mescaline and lysergic acid diethylamide (LSD-25).
