therapy of cancer with receptor tyrosine kinase (RTK) inhibitors, which are usually cytostatic, with conventional chemotherapeutic agents, which are usually cytotoxic, provide an improved treatment option. We have designed, synthesized, and evaluated a series of novel 2,4-diamino-5-substituted furo[2,3-d]pyrimidines with RTK and dihydrofolate reductase (DHFR) inhibitory activity in single molecules, as potential
最近的证据表明,将癌症与通常具有细胞生长抑制作用的受体酪氨酸激酶(RTK)抑制剂与通常具有细胞毒性的常规化学治疗剂联合治疗,可提供更好的治疗选择。我们已经设计,合成和评估了一系列新颖的2,4-二氨基-5-取代的呋喃并[2,3-d]嘧啶类化合物,它们在单个分子中具有RTK和二氢叶酸还原酶(DHFR)抑制活性,作为潜在的抑制细胞生长和细胞毒性的药物具有抗肿瘤活性。使用Wittig反应由2,4-二氨基-5-氯甲基呋喃并[2,3-d]嘧啶和芳基甲基酮合成这些化合物,得到C-8-C-9不饱和类似物,然后将其催化还原为相应的饱和化合物。评价了饱和和不饱和C-8-C-9桥接化合物作为血管内皮生长因子受体(VEGFR-2,Flk,KDR),表皮生长因子受体和血小板源性生长因子受体β(PDGFR-测试版)。在鸡胚绒膜尿囊膜(CAM)分析中,还评估了选定的类似物作为抗血管生成剂。还评估了这些化合物作为人(h)
