  • Patent number: 6770638
    Abstract: Pharmaceutical composite compositions comprising tetrahydroindolones linked to arylpiperazines and derivatives thereof are disclosed. Specifically, composite compositions useful in treating anti-psychotic disorders are disclosed. The composite compositions disclosed herein can effectively ameliorate symptoms and treat psychotic disorders without causing a decrease in cognitive function. Generally, the composite compounds consist of two moieties, moiety A and B in which a tetrahydroindolone comprises a moiety A linked through a linker L to a moiety B, where B is an arylpiperazinyl moiety. The composite compound provides anti-psychotic actively by interaction with GABA, seratoninne and dopamine receptors. The composite molecules with the combined activities will provide treat psychiatric and neurological diseases without cognitive impairment.

  • Patent number: 5399565
    Abstract: Novel substituted pyrazolidinones have been found to exhibit significant binding to cholecystokinin (CCK) receptors and gastrin receptors in the brain and/or peripheral sites such as the pancreas, stomach, and ileum. The pyrazolidinones are CCK and gastrin receptor antagonists and find therapeutic application in the treatment of gastrointestinal disorders, central nervous system disorders and for appetite regulation in warm-blood vertebrates.
