Abstract

This letter describes the further chemical optimization of the picolinamide-derived family of mGlu4 PAMs wherein we identified a 3-amino substituent to the picolinamide warhead that engendered potency, CNS penetration and in vivo efficacy. From this optimization campaign, VU0477886 emerged as a potent (EC50=95nM, 89% Glu Max) mGlu4 PAM with an attractive DMPK profile (brain:plasma Kp=1.3), rat CLp=4.0mL/min/kg, t1/2=3.7h) and robust efficacy in our standard preclinical Parkinson's disease model, haloperidol-induced catalepsy (HIC).

摘要

这封信描述了吡啶甲酰胺衍生的mGlu4 正变构调节剂家族的进一步化学优化,其中我们在吡啶甲酰胺弹头中确定了一个3-氨基取代基,该取代基带来了效力、中枢神经系统渗透性和体内疗效。通过这次优化,VU0477886成为一种强效的(EC50=95nM,89%的谷氨酸最大反应)mGlu4 正变构调节剂,具有吸引人的药物代谢动力学特性(脑:血浆分配系数Kp=1.3),大鼠肝清除率CLp=4.0mL/分钟/千克,半衰期t1/2=3.7小时),并且在我们标准的临床前帕金森病模型——氟哌啶醇诱导的僵住症(HIC)中具有强大的疗效。
