  Potent BRAF kinase inhibitors based on 2,4,5-trisubstituted imidazole with naphthyl and benzothiophene 4-substituents

  摘要：

  The RAS-RAF-MEK-ERK pathway is hyperactivated in 30% of human cancers. BRAF is a serine-threonine kinase, belonging to this pathway that is mutated with high frequency in human melanoma and other cancers thus BRAF is an important therapeutic target in melanoma. We have designed inhibitors of BRAF based on 2,4,5-trisubstituted imidazoles with naphthyl and benzothiophene-4-substituents. Two compounds were discovered to be potent BRAF inhibitors: 1-(6-{2-[4-(2-dimethylamino-ethoxy) phenyl]-5-(pyridin-4-yl)-1H-imidazol-4-yl} benzo[b]thiophen-3-yl)-2,2,2-trifluoroethanol (1i) with BRAF IC50 = 190 nM and with cellular GI(50) = 2100 nM, and 6-{2-[4-(2-dimethylamino-ethoxy)-phenyl]-5-pyridin-4-yl-3H-imidazol-4-yl}-naphthalen-1-ol (1q) with IC50 = 9 nM and GI(50) = 220 nM.

  (Me2N-TP), that allows us to convert an ortho C-H bond to a C-CH3 bond in aromatics and heteroaromatics bearing simple carbonyl groups under mild oxidative conditions. The reaction is powerful enough to methylate all four ortho C-H bonds in benzophenone. The reaction tolerates a variety of functional groups, such as boronic ester, halide, sulfide, heterocycles, and enolizable ketones.

  近年来，芳烃的铁催化 CH 官能化引起了化学家的广泛关注，但由于需要在底物上精心设计导向基团，迄今为止阻碍了苯甲酸和酮等简单芳香羰基化合物的使用，大大减少了其合成公用事业。我们在这里描述了温和反应性甲基铝试剂和用于金属催化的新三齿膦配体 4-(双(2-(二苯基膦基)苯基)膦基)-N,N-二甲基苯胺 (Me2N-TP) 的组合，这使我们能够在温和的氧化条件下将带有简单羰基的芳烃和杂芳烃中的邻位 CH 键转化为 C-CH3 键。该反应足够强大，可以甲基化二苯甲酮中的所有四个邻位 CH 键。该反应耐受多种官能团，如硼酸酯、
