inhibition of the TrkA kinase pathway in pain has been clinically validated by the NGF antibody tanezumab, leading to significant interest in the development of small molecule inhibitors of TrkA. Furthermore, Trk inhibitors having an acceptable safety profile will require minimal brain availability. Herein, we discuss the discovery of two potent, selective, peripherally restricted, efficacious, and
已知神经营养因子家族,神经生长因子(NGF),脑源性神经营养因子(BDNF),神经营养因子3(NT3)和神经营养因子4(NT4)的激素可激活Tropomyosin受体激酶家族(TrkA,TrkB和TrkC)。此外,NGF抗体tanezumab已在临床上验证了疼痛中TrkA激酶途径的抑制作用,从而引起了对TrkA小分子抑制剂开发的极大兴趣。此外,具有可接受的安全性的Trk抑制剂将需要最小的脑可利用性。本文中,我们讨论了发现两个有效的,选择性的,周边限制性的,有效的和耐受性良好的系列pan-Trk抑制剂的发现,该系列成功递送了三种候选质量的化合物10b,13b和19。预测这三种化合物在人体内的代谢清除率较低,不会通过醛氧化酶催化的反应进行,从而解决了与我们目前的泛-Trk开发候选药物PF-06273340相关的潜在清除率预测责任。
