A series of novel, multisubstrate, bicyclic pyrimidine nucleoside inhibitors of human thymidine phosphorylase (TP) is described. Thymidine phosphorylase has been implicated in angiogenesis and plays a significant role in tumor progression and metastasis. The presence and orientation of the phosphonate moiety (acting as a phosphate mimic) in these derivatives were critical for inhibitory activity. The
描述了一系列新型的人胸苷磷酸化酶(TP)的多底物双环嘧啶核苷抑制剂。胸苷磷酸化酶与血管生成有关,在肿瘤的进展和转移中起着重要的作用。这些衍生物中膦酸酯部分的存在和取向(充当磷酸盐模拟物)对于抑制活性至关重要。最具活性的化合物在内部取向上具有膦酸酯基团。这与分子建模结果一致,该分子建模结果显示内异构体蛋白-配体复合物的能量低于外泌体复合物。
