A series of 2,4-diamino pyrimidine (DAPY) derivatives were designed, synthesized, and evaluated as inhibitors of focal adhesion kinase (FAK) with antitumor and anti-angiogenesis activities. Most compounds effectively suppressed the enzymatic activities of FAK, and the IC50s of 11b and 12f were 2.75 and 1.87 nM, respectively. 11b and 12f exhibited strong antiproliferative effects against seven human
一系列 2,4-二氨基嘧啶 (DAPY) 衍生物被设计、合成并评估为具有抗肿瘤和抗血管生成活性的粘着斑激酶 (FAK) 抑制剂。大多数化合物可有效抑制 FAK 的酶活性,11b和12f的 IC 50 s分别为 2.75 和 1.87 nM。11b和12f对七种人类癌细胞表现出强烈的抗增殖作用,对两种过表达 FAK 的胰腺癌细胞(PANC-1 和 BxPC-3)的IC 50值分别为 0.98 μM、0.55 μM 和 0.11 μM、0.15 μM。此外,11b和12f以剂量依赖性方式明显抑制PANC-1细胞的集落形成、迁移和侵袭。同时,根据流式细胞术检测,这两种化合物均能诱导PANC-1细胞凋亡并在G2/M期阻滞细胞周期。蛋白质印迹显示11b和12f有效抑制FAK/PI3K/Akt信号通路并显着降低细胞周期蛋白D1和Bcl-2的表达。此外,化合物11b和12f有效抑制HUVECs的抗增殖并
