  Synthesis and Structure−Activity Relationships of Pyrazine-Pyridine Biheteroaryls as Novel, Potent, and Selective Vascular Endothelial Growth Factor Receptor-2 Inhibitors

  摘要：

  There is much evidence that direct inhibition of the kinase activity of vascular endothelial growth factor receptor-2 (VEGFR-2) will result in the reduction of angiogenesis and the suppression of tumor growth. Palladium-catalyzed C-C bond, C-N bond formation reactions were used to assemble various pyrazine-pyridine biheteroaryls as potent VEGFR-2 inhibitors. Among them, 4-{5-[6-(3-chloro-phenylamino)-pyrazin-2-yl]-pyridin-3-ylamino}-butan-1-ol (39) and N-{5-[6-(3-chloro-phenylamino)-pyrazin-2-yl]-pyridin-3-yl}-N ',N '-dimethyl-ethane-1,2-diamine (41) exhibited the highest kinase selectivity against fibroblast growth factor receptor kinase, platelet-derived growth factor receptor kinase, and glycogen synthase kinase-3. All of these compounds showed good cellular potency to inhibit VEGF-stimulated proliferation of human umbilical vein endothelial cells (HUVEC) but with modest effects on the unstimulated growth of HUVEC. The low inhibition of these compounds to the growth of tumor cell lines, such as HeLa, HCT-116, and A375 further confirms that these VEGFR-2 inhibitors are not cytotoxic agents. The in vivo antitumor activity of 39 and 41 were demonstrated in the A375 human melanoma xenograft nude mice model. Molecular modeling (QSAR analysis) was conducted in an attempt to rationalize the observed structure-activity relationship.

  摘要：

  病理性血管生成与疾病状态相关，例如癌症，糖尿病性视网膜病，类风湿性关节炎，子宫内膜异位和牛皮癣。有许多证据表明，直接抑制血管内皮生长因子受体2（VEGFR-2）的激酶活性将导致血管生成的减少和肿瘤生长的抑制。尝试通过使用钯催化的CC键来优化细胞周期蛋白依赖性激酶1（CDK1）抑制剂，CN键形成反应组装不同的双杂芳基分子，从而意外地发现了吡嗪-吡啶双杂芳基作为一种新型的有效VEGFR- 2种抑制剂。化合物15在VEGFR-2处的IC（50）= 0.084 microM，对成纤维细胞生长因子受体2的选择性非常适中（IC（50）= 0.21 microM），血小板衍生的生长因子受体（IC（50）= 0.36 microM）和糖原合酶激酶3（IC（50）= 0.478 microM），而对表皮生长因子受体（IC（50 ）= 1.36 microM）和胰岛素R激酶（IC（50）= 1.69 micr

  series of potent VEGFR-2 inhibitors. Compound 15, which had IC(50) = 0.084 microM at VEGFR-2, showed very modest selectivity against fibroblast growth factor receptor-2 (IC(50) = 0.21 microM), platelet-derived growth factor receptor (IC(50) = 0.36 microM), and glycogen synthase kinase-3 (IC(50) = 0.478 microM), while it exhibited more than 10-fold selectivity against epidermal growth factor receptor
