A novel series of 1-(aryl aldehyd oxime) uracil derivatives were synthesized, characterized and evaluated for its inhibitory activity against thymidine phosphorylase. Among them, the compound 8d, 8e, 8f, 8g and 8l displayed potent thymidine phosphorylase inhibitory activities with the IC50 values ranging between 0.12 ± 0.05 and 7.2 ± 1.4 μM. And the compounds 8a, 8h, 8i, 8j, 8m, 8n, 8o, 8q, 8s, 8t
合成了一系列新型的1-(芳基醛肟)尿嘧啶衍生物,表征并评价了其对胸苷磷酸化酶的抑制活性。其中,化合物8d,8e,8f,8g和8l表现出有效的胸苷磷酸化酶抑制活性,IC 50值在0.12±0.05和7.2±1.4μM之间。以及化合物8a,8h,8i,8j,8m,8n,8o,8q,8s,8t和8u与标准7DX和TPI相比,IC 50(IC 50为10.7至39.9μM)表现出良好的胸苷磷酸化酶抑制作用。最具生物活性的化合物8l被证明是酶抑制的竞争模式。分子对接分析表明,基于实验结果,这些新合成的化合物在胸苷磷酸化酶的活性结合位点具有相互作用。总的来说,这些结果表明这些化合物是有望用于抗血管生成治疗的胸苷磷酸化酶抑制剂。
