  • Title: Synthesis and evaluation of a series of piperidine-2,6-dione-piperazine (piperidine) derivatives as multireceptor atypical antipsychotics.
    Author: Chen Y, Xu X, Liu X, Liu BF, Zhang G.
    Journal: Arch Pharm (Weinheim); 2012 Nov; 345(11):859-69. PubMed ID: 22886598.
    Abstract:
    In this paper, we report the discovery and the synthesis of novel, potential antipsychotic piperidine-2,6-dione derivatives combining potent dopamine D(2) , D(3) and serotonin 5-HT(1A) , 5-HT(2A) , 5-HT(2C) receptor properties. We describe the structure-activity relationships that led us to the promising derivative: 1-(4-(4-(6-fluorobenzo[d]isoxazol-3-yl)piperidin-1-yl)butyl)-4-(4-chlorophenyl)-piperidine-2,6-dione 5. The unique pharmacological features of compound 5 are a high affinity for dopamine D(2) , D(3) and serotonin 5-HT(1A) , 5-HT(2A) , 5-HT(2C) receptors, together with a low affinity for the H(1) receptor (to reduce the risk of obesity under chronic treatment). In a behavioral model predictive of positive symptoms, compound 5 inhibited apomorphine-induced climbing behavior and MK-801-induced hyperactivity with no extrapyramidal symptoms liability in mice. In particular, compound 5 was more potent than clozapine.
