A strategy to replace the ethylamine side chain of 2,5-dimethoxy-4-iodoamphetamine (DOI, 1a), and 2,5-dimethoxy-4-bromoamphetamine (DOB, 1b) with a cyclopropylamine moiety was successful in leading to compounds with high affinity at the 5-HT2 family of receptors; and the more potent stereoisomer of the cyclopropane analogues had the expected (−)-(1R,2S)-configuration. Screening for affinity at...

Lysergic acid amides were prepared from (R,R)-(-)-, (S,S)-(+)-, and cis-2,4-dimethyl azetidine. The dimethylazetidine moiety is considered here to be a rigid analogue of diethylamine, and thus, the target compounds are all conformationally constrained analogues of the potent hallucinogenic agent, N,N-diethyllysergamide, LSD-25. Pharmacological evaluation showed that...

The racemate and the enantiomers of 1-(3-methoxy-4-methyphenyl)-2- aminopropane (6) and racemic 5-methoxy-6-methyl-2-aminoindan (11) were tested for stimulus generalization in the two-lever drug-discrimination paradigm. Both 6 and 11 were found to substitute with high potency in 3,4-(methylenedioxy)methamphetamine (1) and (S)-1-(1,3-benzodioxol-5-yl)-2-(methylamino)butane (2) trained rats. In...
