BCR-ABL kinase inhibition is an effective strategy for the treatment of chronic myeloid leukemia (CML). Herein, we report compound 3a-P1, bearing a difluoro-indene scaffold, as a novel potent pan-inhibitor against BCR-ABL mutants, including the most refractory T315I mutant. As the privileged (S)-isomer compared to its (R)-isomer 3a-P2, 3a-P1 exhibited potent antiproliferative activities against K562 and
BCR-ABL 激酶抑制是治疗慢性粒细胞白血病 (CML) 的有效策略。在此,我们报告了带有二氟茚支架的化合物3a-P1,它是一种针对 BCR-ABL 突变体(包括最难治的 T315I 突变体)的新型强效泛抑制剂。由于特权 ( S )-异构体与其 ( R )-异构体3a-P2 相比,3a-P1对 K562 和 Ku812 CML 细胞以及 BCR-ABL 和 BCR-ABL T315I BaF3 细胞表现出有效的抗增殖活性,IC 50值为分别为 0.4、0.1、2.1 和 4.7 nM。3a-P1在一系列分析中显示出良好的安全性,包括单剂量毒性、hERG K +, 和遗传毒性。它还显示出良好的小鼠药代动力学特性,具有良好的口服生物利用度 (32%)、合理的半衰期 (4.61 h) 和高暴露 (1386 h·ng/mL)。重要的是,在携带 BCR-ABL T315I的 BaF3 小鼠异种移植模型中,3a-P1表现出比
