process for identifying degrader hits based on the serine/threonine kinase TANK-binding kinase 1 (TBK1) and have generalized the key structural elements associated with degradation activities. Compound 3i is a potent hit (TBK1 DC50 = 12 nM, Dmax = 96%) with excellent selectivity against a related kinase IKKε, which was further used as a chemical tool to assess TBK1 as a target in mutant K-Ras cancer
靶向嵌合体的蛋白水解(PROTAC)是双功能分子,可将E3连接酶募集至目标蛋白质,以促进该蛋白质的泛素化和随后的降解。虽然靶向降解剂的领域还比较年轻,但这种方法成为分化和治疗现实的潜力很强,因此学术机构和制药机构现在都在进入这一有趣的研究领域。在本文中,我们描述了一种基于丝氨酸/苏氨酸激酶TANK结合激酶1(TBK1)识别降解子命中点的广泛适用的过程,并概括了与降解活动相关的关键结构要素。化合物3i命中率很高(TBK1 DC 50 = 12 nM,D max (= 96%)对相关激酶IKKε具有优异的选择性,该激酶还被用作化学工具,以评估TBK1作为突变K-Ras癌细胞中的靶标。
