CYP3A4 (TDI) by members of this structural class. A novel two-step protocol for the synthesis of benzylic sulfonamides was developed to access 11r and analogues. We provide a rationale for the observed selectivity based on X-ray crystallographic evidence and discuss selectivity trends with additional examples. Importantly, 11r provides full inhibition of tumor growth in a c-Met amplified (GTL-16) subcutaneous
该报告记录了优先结合活化激酶构象的蛋白激酶特异性抑制剂的第一个实例:5 H-苯并[4,5]环庚[1,2 - b ]吡啶-5-酮11r(MK-8033) ,这是一种正在研究中的c-Met / Ron双重抑制剂,可用于治疗癌症。11r的设计基于减少该结构类别成员对CYP3A4(TDI)的时间依赖性抑制的愿望。开发了一种新颖的两步合成苄基磺酰胺的方法,以访问11r和类似物。我们根据X射线晶体学证据为观察到的选择性提供了理论依据,并与其他实例讨论了选择性趋势。重要的是11r 在c-Met扩增(GTL-16)皮下肿瘤异种移植模型中提供了对肿瘤生长的完全抑制作用,并且由于对c-Met的一系列致癌性激活突变具有同等效力,因此与无活性形式的激酶抑制剂相比可能具有优势-Met抑制剂不与活性激酶构象优先结合。
