Abstract

Although atypical antipsychotics provide significantly greater efficacy against negative symptoms and cognitive deficits of schizophrenia, improvements in negative symptoms and cognition remain modest. The third generation antipsychotics which combine D2 receptor blockade with 5-HT1A receptor activation appear to provide therapeutic benefits against a broader range of symptoms and are essentially free of EPS liability. In an ongoing effort, we have identified new dihydroquinoline, tetrahydroquinoline and methoxyquinoline derivatives of 1-aryl-4-(diarylmethylene)piperazines and 4-aryl-1-(diarylmethylene)piperidines, which are structural analogs of adoprazine (SLV313). The described compounds have been screened for binding affinities of D2 and 5-HT1A receptors. The structure-activity relationship studies indicated that cyclopentenylpyridine, fluorophenylpyridine and cyclopentenylbenzyl groups significantly contribute to the high-binding affinities of these compounds to D2 and 5-HT1A receptors.
