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。

Bruton’styrosinekinase (Btk) is a nonreceptor cytoplasmic tyrosinekinase involved in B-cell and myeloid cell activation, downstream of B-cell and Fcγ receptors, respectively. Preclinical studies have indicated that inhibition of Btk activity might offer a potential therapy in autoimmune diseases such as rheumatoid arthritis and systemic lupus erythematosus. Here we disclose the discovery and preclinical
