A Mutual Prodrug Ester of GABA and Perphenazine Exhibits Antischizophrenic Efficacy with Diminished Extrapyramidal Effects
摘要:
The perphenazine and fluphenazine GABA esters 3 and 4 evaluated in rat models for antipsychotic activity displayed a significant decrease of catalepsy associated with increased prolactin blood levels. Efficacy was evaluated in the D-amphetamine-induced hyperactivity model, where perphenazine abolished hyperactivity and induced sedation and catalepsy, whereas 3 reduced hyperactivity without sedation or catalepsy. Thus, 3 (BL-1020) constitutes a prototype of novel antipsychotics possessing GABAergic activity. A phase II study is in progress.

Novel chemical conjugates of psychotropic drugs and organic acids, uses thereof in the treatment of psychotic and/or proliferative disorders and diseases and as chemosensitizing agents, and their syntheses are disclosed. The organic acids are selected to reduce side effects induced by the psychotropic drugs and/or to exert an anti-proliferative activity.

A chemical conjugate comprises a first chemical moiety covalently linked to a second chemical moiety, wherein said first chemical moiety is a residue of an anti-psychotic drug residue and further wherein said second chemical moiety is a residue of an organic acid residue having 3-5 carbon atoms, said organic acid residue is selected so as to reduce side effects induced by said anti-psychotic drug when said anti-psychotic drug is administered per se and/or to exert antiproliferative activity.
