Abstract: A series of psychotropic heterobicycloalkylpiperazine derivatives having the structure ##STR1## wherein V is a 3- or 4-membered unsaturated chain, containing all carbon atoms when 4-membered, or when a 3-membered chain, V contains an oxygen or sulfur atom as one of the members; R is H or C.sub.1-4 alkyl; W is CH, N, CH.sub.2, or a chemical bond; X is CH, N, SO.sub.2, or CO, with the proviso that both W and X cannot simultaneously be N; and Z is a heteroaromatic ring system. These compounds are useful antipsychotic and/or anxiolytic agents.

Abstract: Novel thieno[3,2-c]pyridine derivatives of Formula I, ##STR1## in which Z is glutarimide, are useful antipsychotic agents with reduced side-effect liability.

Abstract: A series of psychotropic acyclic amide derivatives having the structure ##STR1## wherein R is alkyl, alkenyl, cycloalkyl- and bicycloalkyl-methyl; and Z is a heterocyclic group comprised of pyrimidine, benzisothiazole, thienopyridine, and furopyridine. These compounds are useful antipsychotic and/or anxiolytic agents.

Abstract: Disubstituted N,N-piperazinyl derivatives are disclosed wherein one substituent is a substituted pyridin-2-yl ring and the second substituent is a butylene chain attached to cyclic imide heterocycles such as azaspiro[4.5]decanedione, dialkylglutarimide, thiazolidinedione, spirocyclopentylthiazolidinedione, or morpholine-2,6-dione. The compounds have psychotropic properties and 2-[4-[4-(2,4-dioxo-1-thia-3-azaspiro[4.5]nonane-3-yl)butyl]-1-piperazinyl] -pyridine-3-carboxaldehyde is a typical embodiment having selective antipsychotic activity.

Abstract: Disubstituted 1,4-piperazinyl derivatives are disclosed wherein one substituent is a bicyclic fused-ring furo-, pyrrolo-, cyclopentadieno-, or thieno-pyridine heterocyclic system and the second substituent is an alkylene chain attached to cyclic imide heterocycles, such as azaspiro[4.5]decanediones, dialkylglutarimides, thiazolidinediones, succinimides, and morpholine-2,6-diones; or a benzylic carbinol moiety. These compounds have potent antipsychotic and serotonin antagonist activities. 4-[4-[4-(4-Furo[3,2-c]pyridinyl)-1-piperazinyl]butyl]-3,5-morpholinedione is an example of a typical embodiment having selective antipsychotic activity.

Abstract: Disubstituted N,N'-piperazinyl derivatives are disclosed wherein one substituent is heteroaryl and the other is alkylene attached to the ring nitrogen of substituted 2,5-pyrrolidinedion-1-yl moieties. The substitution pattern of the pyrrolidinedione ring involves either geminal disubstitution, including spiro ring fusion, or 3,4-phenyl ring fusion to give phthalimide derivatives. Heteroaryl substitution on the other piperazine nitrogen comprises pyridine, pyrimidine, and benzisothiazole ring systems. Representative examples of these compounds demonstrate useful central nervous system effects.
