Abstract
The synthesis of pyrrole analogues of the analgesic drug lefetamine is reported. These derivatives bear the 1-phenyl-2-(1H-pyrrol-1-yl)ethylamino moiety. Compounds were evaluated for analgesic activities in mice by the hot plate and Randall-Selitto tests. Antiinflammatory activity was tested by the carrageenan-induced rat paw edema method. General neuropsychopharmacological effects were also screened. The most interesting compound, N,N-dimethyl-1-phenyl-2-(1H-pyrrol-1-yl)ethylamine, showed an analgesic effect comparable to that of lefetamine, but devoid of the neurotoxicity of this drug.
