Structural models of the complexes/nbetween some of the most representative compounds of this series and the D2 and D3 receptors were/nobtained with the aim of rationalizing the observed experimental results. Moreover, selected compounds/nshowed moderate binding affinity on 5-HT2A which could contribute to reducing the occurrence of extrapyramidal/nside effects as potential antipsychotics.
