TNNI3K inhibitors directed design efforts that produced a novel series of 4,6-diaminopyrimidine inhibitors, an emerging kinase binding motif. Herein, we report a detailed understanding of the intrinsic conformational preferences of the scaffold, which impart high specificity for TNNI3K. Further manipulation of the template based on the conformational analysis and additional structure–activity relationship
嘌呤衍生的一系列TNNI3K抑制剂的结构指导进展指导了设计工作,产生了一系列新颖的4,6-二氨基嘧啶抑制剂,这是一种新兴的激酶结合基序。在本文中,我们报告了对支架的内在构象偏好的详细了解,该偏好赋予TNNI3K高特异性。根据构象分析和进一步的结构-活性关系研究对模板进行进一步操作,可增强激酶的选择性和药代动力学,从而提供了一系列先进的有效抑制剂。优化的化合物(例如GSK854)是鉴定新的心脏药物的合适先导,并且已被用作体内研究工具,旨在确定TNNI3K在心力衰竭中的作用。
