Derivatives of 11-(1-piperazinyl)-5H-pyrrolo[2,1-c][1,4]benzodiazepine as central nervous system agents.

Four 11-(1-piperazinyl)-5H-pyrrolo[2,1-c][1,4]benzodiazepines were prepared and evaluated as central nervous system agents. All were active psychotropic agents as determined by animal screening tests. The most interesting compound, 11-(1-piperazinyl)-5H-pyrrolo[2,1-c][1,4]benzodiazepine, showed dual activity as an antidepressant against tetrabenazine depression and as a neuroleptic as measured by protection vs. amphetamine lethality in grouped mice.
