  target CRAF have been challenging due to the complex nature of RAF signaling, downstream of activated RAS, and the poor overall kinase selectivity of putative RAF inhibitors. Herein, we describe 15 (LXH254, Aversa, R.; et al. Int. Patent WO2014151616A1, 2014), a selective B/C RAF inhibitor, which was developed by focusing on drug-like properties and selectivity. Our previous tool compound, 3 (RAF709; Nishiguchi

  RAS的直接药理抑制作用仍然难以捉摸，由于RAF信号的复杂性质，活化RAS的下游以及假定的RAF抑制剂的总体激酶选择性较差，因此针对CRAF的努力一直具有挑战性。在本文中，我们描述了15（LXH254，Aversa，R .；等人，国际专利WO2014151616A1，2014），一种选择性的B / C RAF抑制剂，其通过关注药物样性质和选择性而开发。我们以前的工具化合物，3（RAF709;西口，GA;等人，J.医学化学式。2017年，60（4969），在临床前模型中是有效的，选择性的，有效的和良好的耐受性，但是人类固有的高清除率阻止了进一步的发展，并促使人们进一步研究紧密的类似物。基于结构的方法产生了带有醇侧链的吡啶系列，该侧链可以与DFG环相互作用并显着提高了细胞效能。进一步缓解人类固有的清除和时间依赖性抑制导致15的发现。由于其优异的性能，它已经通过毒理学研究进展，并正在1期临床试验中进行测试。
