Discovery of 4-methyl-N-(4-((4-methylpiperazin- 1-yl)methyl)-3-(trifluoromethyl)phenyl)-3-((6-(pyridin-3-yl)-1H-pyrazolo[3,4-d]pyrimidin-4-yl)-oxy)benzamide as a potent inhibitor of RET and its gatekeeper mutant

transfection (RET) plays pivotal roles in several cancers, including thyroid carcinoma and non-small cell lung cancer (NSCLC). Currently, there are several FDA-approved RET inhibitors, but their indication is limited to thyroid cancer, and none can overcome their gatekeeper mutants (V804L and V804M). Here, we report the discovery of 9x representing a new chemotype of potent and selective RET inhibitors, using
转染过程中重排的受体酪氨酸激酶(RET)在几种癌症中起关键作用,包括甲状腺癌和非小细胞肺癌(NSCLC)。当前,有几种FDA批准的RET抑制剂,但它们的适应症仅限于甲状腺癌,没有一个能克服其Gatekeeper突变体(V804L和V804M)。在这里,我们报告使用II型激酶抑制剂的合理设计策略,发现了9x代表有效和选择性RET抑制剂的新化学型的发现。9x对NSCLC相关致癌融合KIF5B-RET和CCDC6-RET以及关守突变体转化的Ba / F3细胞均显示出优异的抗增殖活性,且GI 50最低9 nM,对野生型RET和RET突变蛋白具有显着的抑制活性,最佳IC 50为4 nM。更重要的是,9x还显示出对RET阳性NSCLC细胞LC-2 / ad的纳摩尔效价,但对一组RET阴性癌细胞(如A549,H3122,A375或亲代Ba / F3细胞)没有纳摩尔效价,表明其选择性'目标上的效果。在小鼠
