receptor‐2 (VEGFR‐2) is an important factor in angiogenesis. In this work, a novel series of thiazolo[5,4‐d]pyrimidine derivatives inhibiting angiogenesis were rationally designed and synthesized. Their inhibitory activities against human umbilical vein endothelial cells (HUVEC) were investigated in vitro. 1‐(4‐Fluorophenyl)‐3‐4‐[(5‐methyl‐2‐phenyl[1,3]thiazolo[5,4‐d]pyrimidin‐7‐yl)amino]phenyl}urea (19b)
血管生成对肿瘤生长至关重要,抑制血管生成已被视为癌症治疗的一种有前途的方法。血管内皮生长因子受体-2 (VEGFR-2) 是血管生成的重要因素。在这项工作中,合理设计和合成了一系列抑制血管生成的新型噻唑并[5,4-d]嘧啶衍生物。在体外研究了它们对人脐静脉内皮细胞 (HUVEC) 的抑制活性。1-(4-氟苯基)-3-4-[(5-甲基-2-苯基[1,3]噻唑并[5,4-d]嘧啶-7-基)氨基]苯基}脲(19b)和1-(3-氟苯基)-3-4-[(5-methyl-2-phenyl[1,3]thiazolo[5,4-d]pyrimidin-7-yl)amino]phenyl}urea (19g)对 HUVEC 增殖最有效的抑制作用(IC50 分别为 12.8 和 5.3 μm)。化合物19g可抑制人脐静脉内皮细胞的迁移。这些结果支持进一步研究这些化合物作为有效的抗癌剂。
