Synthesis of new N-substituted benzodiazepine derivatives with potential anxiolytic activity

Abstract

In continuation of the development of antipsychotic and anxiolytic agents with a reduced propensity toward extrapyramidal side-effects, a series of N-aminoalkyl derivatives of (s)-(+)-2,3-dihydro-1H-pyrrolo[2,1-c][1,4]benzodiazepine-5,11-(10H, 11aH)-dione was prepared. Evaluation of these compounds in revealed a very low affinity for 5-HT1A receptor.
