  Discovery of New Benzothiazole-Based Inhibitors of Breakpoint Cluster Region-Abelson Kinase Including the T315I Mutant

  摘要：

  The existence of drug resistance caused by mutations in the break-point cluster region-Abelson tyrosine kinase (Bcr-Abl) kinase domain remains a clinical challenge due to limited effective treatment options for chronic myeloid leukemia (CML). Herein we report a novel series of benzothiazole-based inhibitors that are effective against wild-type and T315I mutant Bcr-Abl kinases. The original hit compound, nocodazole, was extensively modified through a structure-based drug design strategy, especially by varying the groups at the C2 and C6 positions of the scaffold. In addition, the introduction of water-solubilizing groups at the terminal ethyl group resulted in enhanced physicochemical properties and potency in cellular inhibition. Several compounds inhibited the kinase activity of both wild-type Bcr-Abl and the T315I mutant with IC50 values in the picomolar range and exhibited good antiproliferative effects on Ba/F3 cell lines transformed with either wild-type or T315I mutant Bcr-Abl.

  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。
