  摘要：

  基于与参考化合物的结构相似性，设计，合成了一系列1,3,5-triazin-2,4-dione及其融合类似物，并对其体外胸苷磷酸化酶抑制潜力进行了评估。发现单环类似物是无活性的。在合成的不同稠合衍生物中，在C7 / C4处具有酮基（C = O）和在C5 / C2位置具有硫酮基（C = S）的化合物显示出与阳性对照7-脱氮黄嘌呤（7-DX）相当的TP抑制活性。（IC 50值= 42.63μM）。进行了目标化合物与胸苷磷酸化酶的分子对接，以说明关于合理的配体-酶结合相互作用的重要结构信息。

  Thirty-three 1,2,4-triazolo[1,5-a][1,3,5]triazin-5,7-dione and its 5-thioxo analogues were designed and synthesized which contained different substituents at meta- and/or para-positions of 2-phenyl or 2-benzyl ring attached to the fused ring structure. The preliminary pharmacological evaluation demonstrated that the 5-thioxo analogues of 1,2,4-triazolo[1,5-a][1,3,5]triazine exhibited a varying degree of inhibitory activity towards thymidine phosphorylase, comparable or better than reference compound, 7-Deazaxanthine (7-DX, 2) (IC50 value = 42.63 mu M). Moreover, compounds 5q and 6i displayed a mixed-type of inhibitory mechanism in the presence of variable concentrations of thymidine (dThd). In addition, selected compounds were found to have a noticeable inhibitory effect on the expression of angiogenesis markers, including VEGF and MMP-9 in MDA-MB-231 breast cancer cells.

  In our lead finding program, a series of 1,2,4‐triazolo[1,5‐a][1,3,5]triazine derivatives were synthesized, and their in vitro thymidine phosphorylase inhibitory potential was explored. Among the different derivatives, compounds having keto group (C = O) at C7 and thioketo group (C = S) at C5 positions showed varying degrees of TP inhibitory activity comparable with positive control, 7‐deazaxanthine (7‐DX, 2) (IC50 value = 42.63 μm). Enzyme inhibition kinetics study suggested that compound IVn behaved as a mixed‐type inhibitor of the enzyme with respect to thymidine (dThd) as a variable substrate. Compound IVn was also found to inhibit PMA‐induced MMP‐9 expression in MDA‐MB‐231 cells at sublethal concentrations. Computational docking study was performed to illustrate the enzyme inhibition kinetics and to explore the ligand–enzyme interactions.
