Succinimide Derivatives. II. Synthesis and Antipsychotic Activity of N-(4-(4-(1,2-Benzisothiazol-3-yl)-1-piperazinyl)butyl)-1,2-cis-cyclohexanedicarboximide (SM-9018) and Related Compounds.
Cyclicimides bearing omega-(4-benzisothiazol-3-yl-1-piperazinyl)alkyl moieties were synthesized and tested for antipsychotic activity. The in vitro binding affinities of these compounds were examined for dopamine 2 (D2) and serotonin 2 (5-HT2) receptor sites. Structure-activity relationships within these series are discussed. One of these compounds, N-[4-[4-(1,2-benzisothiazol-3-yl)-1-piperazinyl]butyl]-1
