cancers. The solvent front and xDFG mutations induced by larotrectinib and entrectinib result in acquired resistance in advanced-stage patients. In this study, we report a highly potent and selective type II TRK inhibitor, 40l, developed using a structure-based design strategy. Compound 40l significantly suppressed Km-12, Ba/F3-TRKAG595R, and Ba/F3-TRKAG667C cell proliferation. In biochemical and cellular
原肌球蛋白受体激酶 (TRK) 是治疗NTRK融合癌症的一个有前景的靶点。 larotrectinib 和 entrectinib诱导的溶剂前沿和 xDFG 突变导致晚期患者获得性耐药。在这项研究中,我们报告了一种高效、选择性的 II 型 TRK 抑制剂40l ,它是使用基于结构的设计策略开发的。化合物40l显着抑制Km-12、Ba/F3-TRKA G595R和Ba/F3-TRKA G667C细胞增殖。在生化和细胞测定中, 40l对 TRKA G667C显示出比阳性对照 Selitrectinib 更好的抑制活性。此外,它还以剂量依赖性方式诱导 Ba/F3-TRKA G595R和 Ba/F3-TRKA G667C细胞凋亡。此外, 40l对一组 41 种激酶表现出良好的选择性。体外试验表明40l具有出色的血浆稳定性和中等的肝微粒体稳定性。基于上述结果,化合物40l可以进一步优化以克服溶剂前沿和xDFG
