selective small-molecule inhibitors of ABL kinase by selectively targeting the conserved catalytic lysine in the enzyme. We showed the resulting compounds were cell-active, capable of covalently engaging endogenous ABL kinase in K562 cells with long-residence time and few off-targets. We further validated the generality of this strategy by developing EBA-based irreversible inhibitors against EGFR (a kinase)
近年来,以赖氨酸为靶点的不可逆共价抑制剂引起了越来越多的兴趣,特别是在激酶研究领域。尽管取得了令人鼓舞的进展,但很少有化学方法可用于开发专门针对赖氨酸的、选择性的和细胞活性的抑制剂。我们在此报告了一种基于 2-乙炔基苯甲醛 (EBA) 的赖氨酸靶向策略,通过选择性靶向酶中保守的催化赖氨酸来生成 ABL 激酶的有效且选择性的小分子抑制剂。我们证明所得化合物具有细胞活性,能够与 K562 细胞中的内源 ABL 激酶共价结合,且停留时间长且脱靶很少。我们通过开发基于 EBA 的针对 EGFR(一种激酶)和 Mcl-1(一种非激酶)的不可逆抑制剂,进一步验证了该策略的普遍性,这些抑制剂与每个靶点内的催化和非催化赖氨酸发生共价反应。
