intervention. To deliver the safety profile required for chronic, nonlife threatening pain indications, highly kinase-selective Trk inhibitors with minimal brain availability are sought. Herein we describe how the use of SBDD, 2D QSAR models, and matched molecular pair data in compound design enabled the delivery of the highly potent, kinase-selective, and peripherally restricted clinical candidate PF-06273340
由神经生长因子(NGF),脑源性神经营养因子(BDNF),神经营养蛋白3(NT3)和神经营养蛋白4(NT4)组成的神经营养蛋白生长因子家族与慢性疼痛的生理学有关。鉴于抗NGF单克隆抗体(mAb)疗法的临床疗效,人们对开发神经营养蛋白活性的小分子调节剂非常感兴趣。神经营养蛋白通过酪氨酸激酶受体的原肌球蛋白相关激酶(Trk)家族发出信号,因此Trk激酶抑制作用代表了潜在的“药物滥用”干预点。为了提供对慢性,无生命威胁的疼痛适应症所需的安全性,寻求具有最小脑可利用性的高激酶选择性Trk抑制剂。在此,我们描述如何使用SBDD,2D QSAR模型,
