Optimization of the pharmacokinetic (PK) properties of a series of activators of adenosine monophosphate-activated protein kinase (AMPK) is described. Derivatives of the previously described 5-aryl-indole-3-carboxylic acid clinical candidate (1) were examined with the goal of reducing glucuronidation rate and minimizing renal excretion. Compounds 10 (PF-06679142) and 14 (PF-06685249) exhibited robust
描述了一系列单磷酸腺苷活化蛋白激酶(AMPK)激活剂的药代动力学(PK)特性的优化。为了降低葡萄糖醛酸化率并最小化肾脏排泄,对先前描述的5-芳基-吲哚-3-羧酸临床候选药物(1)的衍生物进行了检查。化合物10(PF-06679142)和14(PF-06685249)在大鼠肾脏中显示出AMPK的强活化,以及在临床前物种中具有所需的口服吸收,低血浆清除率和可忽略的肾脏清除率。鉴定了大鼠体内肾清除率与人和大鼠肾有机阴离子转运蛋白(人OAT /大鼠燕麦)的体外摄取的相关性。极性功能基团的变化对于减轻由Oat3转运蛋白介导的活动性肾脏清除至关重要。将6-氯吲哚核心修饰为4,6-二氟吲哚或将5-苯基取代基修饰为取代的5-(3-吡啶基)基团可改善代谢稳定性,同时最大程度降低OAT3主动转运的可能性。
