Indoline and piperazine containing derivatives as a novel class of mixed D(2)/D(4) receptor antagonists. Part 2: asymmetric synthesis and biological evaluation.
A series of chiral benzylpiperazinyl-1-(2,3-dihydro-indol-1-yl)ethanone derivatives were prepared and examined for their affinity at dopamine D(2) and D(4) receptors. Three compounds having D(2)/D(4) affinity ratios approximating that found for the atypical neuroleptic clozapine were further evaluated in behavioral tests of antipsychotic efficacy and motor side effects.
