Charcot-Marie-Tooth disease type 2A (CMT2A), for which there is currently no treatment. Small-molecule activators of MFN1 and MFN2 enhance mitochondrial fusion and offer promise as therapy for this condition, but prototype compounds have poor pharmacokinetic properties. Herein, we describe a rational design of a series of 6-phenylhexanamide derivatives whose pharmacokinetic optimization yielded a 4-hydroxycyclohexyl
线粒体融合蛋白线粒体融合素(MFN)2的突变会导致慢性神经退行性疾病2型Charcot-Marie-Tooth病(CMT2A),目前尚无治疗方法。MFN1和MFN2的小分子激活剂可增强线粒体融合,并有望作为治疗该病的方法,但原型化合物的药代动力学性能较差。在这里,我们描述了一系列6-苯基己酰胺衍生物的合理设计,其药代动力学优化产生了4-羟基环己基类似物13,具有临床前候选药物的效力,选择性和口服生物利用度。研究13顺式-和反式-4-羟基环己基异立体异构体意外地揭示了反式13B的功能和蛋白质结合。临床上对13B的吸收,分布,代谢和排泄(ADME)和体内靶标参与研究支持进一步开发6-苯基己酰胺衍生物作为人类CMT2A的治疗剂。
