Abstract
A series of 5-p-substituted phenyl-pyrrole-3-carboxamide derivatives was designed as hybrid analogs of the dopamine D2-like 5-phenyl-pyrrole and heterocyclic carboxamide antipsychotics. The title compounds were synthesized and evaluated for dopamine D2-like receptor by means of [3H]YM-09151-2 receptor binding assay. The compound bearing a 1-ethyl-2-methyl-pyrrolidine moiety as the basic part of 5-phenyl-pyrrole-3-carboxamide derivative 1a together with its 2-chloro analog 1f were found to possess affinity in the low micromolar range. Substituted phenyl-pyrrolecarboxamides containing groups such as F, Cl, NO2, CH3, at the 4-position of the phenyl ring, gave ligands with lower D2-like affinity.
