摘要
精神分裂症是一种使人衰弱的精神障碍,患病率相对较高(约1%),在此期间会出现积极的表现(例如精神病状态)和消极的症状(例如退出社交生活)。此外,一些研究人员认为认知障碍是精神分裂症症状的一个独特领域。多巴胺活性的不平衡,即纹状体中这种神经递质的过度释放和额叶前额皮质中的量不足,被认为是造成这些组表现的部分原因。第二代抗精神病药目前是精神分裂症的标准治疗方法。然而,现有的治疗有时是无效的,并且具有严重的副作用,例如锥体外系症状。因此,迫切需要寻找该疾病的替代治疗选择。这篇综述总结了最近在磷酸二酯酶10A(PDE10A)的临床前和临床研究的结果,磷酸二酯酶10A在哺乳动物纹状体中高度表达,作为治疗精神分裂症的潜在药物靶标。根据文献数据,不仅选择性的PDE10A抑制剂而且双重的PDE2A / 10A和PDE4B / 10A抑制剂以及具有PDE10A抑制能力的多功能配体都是可以结合抗精神病药,预知性药物和抗抑郁药功能的化合物。因此,设计此类化合物可能构成精神分裂症潜在药物的新研究方向。尽管先前的选择性PDE10A抑制剂治疗精神分裂症的临床试验失败,但目前正在临床上研究具有这种作用机制的新化合物,因此,仍需要寻找选择性和多靶点PDE10A的新抑制剂。
