A functional high throughput screen and subsequent multidimensional, iterative parallel synthesis effort identified the first muscarinic acetylcholine receptor (mAChR) negative allosteric modulator (NAM) selective for the M5 subtype. ML375 is a highly selective M5 NAM with submicromolar potency (human M5 IC50 = 300 nM, rat M5 IC50 = 790 nM, M1-M4 IC50 > 30 μM), excellent multispecies PK, high CNS penetration, and enantiospecific inhibition.
一项功能性高通量筛选和随后的多维、迭代平行合成工作,鉴定出首个选择性作用于 M5 亚型的毒蕈碱型乙酰胆碱受体(mAChR)负变构调节剂(NAM)。ML375 是一种高度选择性的 M5 NAM,具有亚微摩尔效力(人 M5 IC50=300 nM,大鼠 M5 IC50=790 nM,M1-M4 IC50>30 μM),优秀的多物种 PK,高中枢神经系统穿透性,以及对映体特异性抑制。
