现在人们普遍认为,受体可以在没有刺激配体的情况下调节细胞信号通路,而逆激动剂可以降低这种与配体无关或“构成”受体的活性。5-羟色胺5-HT2A和5-HT2C受体在体外和体内均表现出组成受体活性。每一种都被确定为治疗精神分裂症的靶点。此外,大多数(如果不是全部的话)非典型抗精神病药物在5-HT2A和5-HT2C受体上都具有逆激动剂特性。本文描述了我们目前对非典型抗精神病药物在体外和体内对5-HT2A/2C受体亚型的拮抗作用的了解。利用抗精神病药物的逆激动剂特性可能为药物开发提供新的途径。
It is now well accepted that receptors can regulate cellular signaling pathways in the absence of a stimulating ligand, and inverse agonists can reduce this ligand-independent or “constitutive” receptor activity. Both the serotonin 5-HT2A and 5-HT2C receptors have demonstrated constitutive receptor activity in vitro and in vivo. Each has been identified as a target for the treatment of schizophrenia. Further, most, if not all, atypical antipsychotic drugs have inverse agonist properties at both 5-HT2A and 5-HT2C receptors. This paper describes our current knowledge of inverse agonism of atypical antipsychotics at 5-HT2A/2C receptor subtypes in vitro and in vivo. Exploiting inverse agonist properties of antipsychotic drugs may provide new avenues for drug development.
