The serotonin (5-HT) receptor affinities and behavioral (discriminative stimulus) properties of a series of 4-substituted derivatives of 1-(2,5-dimethoxyphenyl)-2-aminopropane (2,5-DMA) were investigated. The substituents at the 4-position included H, OMe, OEt, Me, Et, F, Br, I and NO2. Substituent lipophilicities (.pi. values) of these functionalities had a minimal effect on either 5-HT receptor affinity or behavioral activity. Those derivatives previously found to be most potent in human studies possessed significant affinity for 5-HT receptors. When rats trained to discriminate (.+-.)-1-(2,5-dimethoxy-4-methylphenyl)-2-aminopropane (DOM) from saline were used, generalization was found to occur upon administration of the 4-substituted 2,5-DMA derivatives. Because a direct relationship exists between the ED50 values obtained from these discrimination studies and human hallucinogenic potencies, the discriminative stimulus paradigm with DOM as a training drug may be a useful tool for comparing the quantitative and qualitative (DOM-like) effects produced by certain hallucinogenic agents.
