胸苷磷酸化酶(TP)是一种促进肿瘤生长和转移的酶,因此是有吸引力的可药物治疗靶标。使用已报道的TP抑制剂7-脱氮黄嘌呤(7DX)作为先导化合物;进行这项研究是为了评估吡唑并[1,5- a ] [1,3,5]三嗪-2,4-二酮和吡唑并[1,5- a ] [1,3,5]三嗪-2- thioxo-4-ones将表现出TP抑制活性。吡唑并[1,5- a ] [1,3,5]三嗪核是通过将1,3,5-三嗪环环化到吡唑支架上的反应构建的。在合成和测试的52种化合物中,发现1,3-二氢-吡唑并[1,5- a ] [1,3,5] triazin-2-thioxo-4-ones对TP表现出不同程度的抑制活性。 。最好的化合物17p带有对位取代的五氟硫基的,其IC 50值为0.04μM, 在相同的生物测定条件下,其效价是7DX(IC 50 = 32μM)的800倍左右。研究结果表明,在吡唑并[1,5- a ] [1

5-triazin-2,4-dione and their fused analogues was designed, synthesized and their in vitro thymidine phosphorylase inhibitory potential was evaluated. The monocyclic analogues were found to be inactive. Among the different fused derivatives synthesized, compounds having keto group (C=O) at C7/C4 and thioketo group (C=S) at C5/C2 position showed TP inhibitoryactivity comparable to positive control, 7-deazaxanthine
