Analogues of 2-amino-N-(4-(4-(1, 2-benzisothiazol-3-yl)-1-piperazinyl)-butyl) benzamide hydrochloride (1192U90) were prepared and evaluated in receptor binding assays for the dopamine D2, serotonin 5-HT1a, and serotonin 5-HT2 receptors. Eight compounds have been synthesized in which the amide group of 1192U90 has been replaced with a variety of functional groups (ie ester, ketone, thioamide, butyramide, butyranilide, sulfonamide, ...
