roles in the treatment of leukemia, and studies confirmed that the synergetic inhibition against Btk and PI3Kδ could gain an optimal response. Herein, a series of novel benzofuro[3,2-b]pyridin-2(1H)-one derivatives were designed and synthesized as dual Btk/PI3Kδ kinases inhibitors for the treatment of leukemia. Studies indicated that most compounds could suppress the proliferation of multiple leukemia
Btk抑制剂和PI3Kδ抑制剂在白血病的治疗中起着至关重要的作用,研究证实,对Btk和PI3Kδ的协同抑制作用可获得最佳反应。在此,设计并合成了一系列新颖的苯并呋喃[3,2 - b ]吡啶-2-2 (1 H)-one衍生物作为双Btk /PI3Kδ激酶抑制剂,用于治疗白血病。研究表明,大多数化合物可以在体外以低微摩尔浓度抑制多种白血病或淋巴瘤细胞(Raji,HL60和K562细胞)的增殖。进一步的激酶分析确定了几种化合物可以同时抑制Btk激酶和PI3Kδ激酶。其中,化合物16b表现出最佳的抑制活性(Btk:IC 50 = 139 nM;PI3Kδ:IC 50 = 275 nM),与PI3Kβ/γ相比,对PI3Kδ表现出一定的选择性。最后,结合对接结果对目标化合物的比吸收率进行了初步讨论。简而言之,16b具有通过同时抑制Btk激酶和PI3Kδ激酶而进一步优化作为抗白血病药物的潜力。
