In this study, a series of novel Isoquinolinone derivatives were synthesized as potential multi-target antipsychotics. Among these, compound 13 showed high affinity for dopamine D2 and serotonin 5-HT1A, 5-HT2A, 5-HT6, and 5-HT7 receptors, showed low affinity for off-target receptors (5-HT2C, H1, and α1), and negligible effects on ether-a-gogo-related gene (hERG; i.e., reduced QT interval prolongation)
在这项研究中,合成了一系列新型异喹啉酮衍生物作为潜在的多目标抗精神病药。其中,化合物13对多巴胺D 2和5-羟色胺5-HT 1A,5-HT 2A,5-HT 6和5-HT 7受体显示出高亲和力,对脱靶受体(5-HT 2C, ħ 1,α 1),并在醚-A-GOGO相关基因(可忽略影响的hERG;即,减少QT间期延长)。动物行为研究表明,化合物13逆转了APO引起的运动过度,MK-801引起的运动过度和DOI引起的头皮抽搐。而且,与利培酮相比,化合物13表现出高的急性毒性阈值,没有引起僵直的倾向,并且不引起催乳激素分泌或体重增加。此外,在强迫游泳测试,尾巴悬吊测试和新型物体识别测试中,用化合物13进行治疗可改善抑郁症和认知障碍。另外,化合物13在大鼠中具有良好的药代动力学特征。因此,化合物13的抗精神病药样作用表明它可能对开发用于治疗精神分裂症的新型药物有用。
