In a continuing program to discover antipsychotic agents with a reduced propensity toward extrapyramidal side-effects, a series of N-alkoxyimides and -amides was prepared. Evaluation of these compounds in vitro revealed affinities for D2, 5HT2 and 5HT1A receptors. Several members of the series displayed a profile indicative of potential antipsychotic activity in preclinical assays. The most potent compound in these assays, 7, also displayed possible effectiveness for the negative symptoms of schizophrenia. The synthesis of these compounds and details of their structure-activity relationships are described.
