disrupting protein-protein interactions. Small organic molecules that target these less conserved regions might serve as tools for chemical biology research and to probe alternative strategies in targeting protein kinases in disease settings. Here, we present the structure-based design and synthesis of a focused library of 2-arylquinazoline derivatives to target the lipophilic C-terminal binding pocket
在蛋白激酶研究中,识别和解决除高度保守的ATP口袋以外的小分子结合位点引起了人们的极大兴趣,因为这一研究领域使我们对激酶功能的理解超出了催化磷酸转移的范围。此类替代结合位点可能涉及通过细微的构象变化来改变激活状态,控制细胞酶的定位或介导和破坏蛋白质-蛋白质相互作用。靶向这些保守程度较低的区域的有机小分子可作为化学生物学研究的工具,并探索针对疾病环境中蛋白激酶的替代策略。在这里,我们介绍了基于结构的设计和合成的2-芳基喹唑啉衍生物的聚焦库,以靶向p38中的亲脂性C末端结合口袋α MAPK,为获得清晰的生物功能尚未被识别。与p38的配体的相互作用α MAPK通过SPR测定分析,并用蛋白质X射线晶体学验证。
