campaign with more than 1600 compounds, which were applied against wild-type Her2 and its mutant variant Her2-A775_G776insYVMA. The resulting inhibitors were designed to covalently target a reactive cysteine in the binding site of Her2 and were further optimized by means of structure-based drug design utilizing a set of obtained complex crystal structures. In addition, the analysis of binding kinetics and
突变或扩增的Her2充当非小细胞肺癌的驱动因子,或介导抵抗小分子抑制剂对其家族成员表皮生长因子受体的抑制作用。迄今为止,缺乏可用于临床常规的靶向Her2的小分子抑制剂,因此,进行了新型抑制剂的开发。在这项研究中,完善的吡咯并嘧啶支架被结构化主题修饰,该结构主题来自对1600多种化合物的筛选活动,这些化合物被应用于野生型Her2及其突变体Her2-A775_G776insYVMA。设计所得的抑制剂以在Her2的结合位点共价靶向反应性半胱氨酸,并通过利用一组获得的复杂晶体结构的基于结构的药物设计进一步优化。
