novel, potent, and selective reversible ERK1/2 inhibitors from a low-molecular-weight, modestly active, and highly promiscuous chemical start point, compound 4. To guide and inform the evolution of this series, inhibitor binding mode information from X-ray crystal structures was critical in the rapid exploration of this template to compound 35, which was active when tested in in vivo antitumor efficacy
有许多针对RAS / RAF / MEK / ERK信号通路的小分子抑制剂已被批准或正在针对多种疾病适应症进行肿瘤学临床开发。目前,对ERK1 / 2的抑制具有重要意义,因为在临床前模型中已显示出对BRAF和MEK抑制剂具有耐药性的细胞系可保持对ERK1 / 2抑制的敏感性。本文报道了我们最近的工作,从低分子量,中等活性和高度混杂的化学起点化合物4中鉴定出新颖,有效和选择性可逆的ERK1 / 2抑制剂。为了指导和告知该系列的进展,X射线晶体结构的抑制剂结合模式信息对于快速探索该模板以形成化合物至关重要。35,当在体内抗肿瘤功效实验中测试时是有活性的。
