inhibit human thymidylate synthase (hTS) for cytotoxic effects in single agents. The synthesis of these compounds involved the nucleophilic displacement of the common intermediate 5-chloro-9H-pyrimido[4,5-b]indole-2,4-diamine with appropriate benzenethiols. The inhibitory potency of both these single agents against VEGFR-2, PDGFR-β, and hTS is better than or close to standards. In a COLO-205 xenograft
抗血管生成剂 (AA) 与细胞毒剂的组合在癌症治疗中显示出巨大的前景,目前正在进行多项此类临床试验。我们设计、合成并评估了两种化合物,它们分别抑制血管内皮生长因子受体 2 (VEGFR-2) 和血小板衍生生长因子受体 β (PDGFR-β) 以产生抗血管生成作用,并且还抑制人胸苷酸合酶 (hTS ) 用于单一药物的细胞毒性作用。这些化合物的合成涉及常见中间体 5-chloro-9 H - pyrimido[4,5- b]indole-2,4-diamine 与适当的苯硫醇。这两种单一药物对 VEGFR-2、PDGFR-β 和 hTS 的抑制效力优于或接近标准。在 COLO-205 异种移植小鼠模型中,与标准药物以及对照和因此在体内证明了有效的肿瘤生长抑制、转移抑制和抗血管生成作用。这些化合物在单一药剂中提供联合化疗的潜力。
