  Synthesis, anti-thymidine phosphorylase activity and molecular docking of 5-thioxo-[1,2,4]triazolo[1,5-a][1,3,5]triazin-7-ones

  摘要：

  In our lead finding program, a series of 5-thioxo-[1,2,4] triazolo[1,5-a][1,3,5]triazin-7-ones and their 5-thio- alkyl derivatives were designed and synthesized which contained different substituents at ortho-position of 2-phenyl ring attached to the fused ring structure. The preliminary pharmacological evaluation demonstrated that the synthesized compounds exhibited a varying degree of inhibitory activity towards thymidine phosphorylase (TP), comparable to reference compound, 7-Deazaxanthine (7-DX, 2) (IC50 value = 42.63 mu M). The study also inferred that the ortho-substituted group at the phenyl ring and 5-thio-alkyl moiety imparted steric hindrance effects in the binding site of the enzyme, leading to a reduced inhibitory response. In addition, compound 3a was identified as a mixed-type inhibitor of TP. Moreover, computational docking study was performed to illustrate the important structural information on the plausible ligand-enzyme binding interactions. (C) 2013 Elsevier Inc.

  demonstrated. The most practical and general method for the preparation of 5-aza-isoguanines involved a regioselective reaction of ethoxycarbonyl isothiocyanate with a 5-aminotriazole. The intramolecular ring closure of the resulted product followed by the S-methylation afforded 7-methylthio-2-phenyl-1,2,4-triazolo[1,5-a][1,3,5]triazin-5-one, which could be effectively aminated with various amines.

  嘌呤等排体在药物设计和开发中提供了极好的机会。使用天然嘌呤的等排体作为构建新治疗剂的支架已成为药物化学的有效策略。受到与异鸟嘌呤的相似性的启发，我们尝试开发一种实用的方法来制备 5-氮杂-异鸟嘌呤。探索了几种合成方法，以建立用于制备这些化合物的稳健通用方案。证明了 1,2,4-三唑并[1,5-a][1,3,5]三嗪（5-氮杂嘌呤）的 C-5 和 C-7 亲电中心对亲核试剂的反应性存在显着差异。制备 5-氮杂-异鸟嘌呤的最实用和通用的方法涉及乙氧羰基异硫氰酸酯与 5-氨基三唑的区域选择性反应。所得产物的分子内闭环，然后进行 S-甲基化，得到 7-甲硫基-2-苯基-1,2,4-三唑并[1,5-a][1,3,5]triazin-5-one，可与各种胺有效胺化。由此产生的 5-氮杂-异鸟嘌呤类似于一种已知的嘌呤核苷磷酸化酶抑制剂，对于作为潜在抗癌剂的进一步研究可能很有趣。

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 inhibitory activity comparable to positive control, 7-deazaxanthine

  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.
