Angiogenesis inhibition is a key step towards the designing of new chemotherapeutic agents. In a view to preparing new molecular entities for cancer treatment, eighteen 1,2,3-triazole-uracil ensembles 5a–r were designed and synthesized via the click reaction. The ligands were well characterized using 1H-, 13C-NMR, elemental analysis and ESI-mass spectrometry. The in silico binding propinquities of the ligands were studied sequentially in the active region of VEGFR-2 using the Molegro virtual docker. All the compounds produced remarkable interactions and potentially inhibitory ligands against VEGFR-2 were obtained with high negative binding energies. Drug-likeness was assessed from the ADME properties. Cytotoxicity of the test compounds was measured against HeLa and HUH-7 tumor cells and NIH/3T3 normal cells by MTT assay. Compound 5h showed higher growth inhibition activity than the positive control, 5-fluorouracil (5-FU), against both HeLa and HUH-7 cells with IC50 values of 4.5 and 7.7 μM respectively. Interestingly, the compounds 5a–r did not show any cytotoxicity towards the normal cell lines. The results advance the position of substituted triazoles in the area of drug design with no ambiguity.
抑制血管生成是设计新化疗药物的关键步骤。为了为癌症治疗准备新的分子实体,设计并合成了18个1,2,3-三唑-尿嘧啶合成物5a–r,通过点击反应合成。使用1H-、13C-NMR、元素分析和ESI-质谱对配体进行了良好的表征。通过Molegro虚拟分子对接研究了配体在VEGFR-2活性区域的分子亲和性。所有化合物都产生了显著的相互作用,得到了具有高负结合能量的潜在抑制配体对VEGFR-2的作用。从ADME性质评估了药物相似性。通过MTT实验测量了试验化合物对HeLa和HUH-7肿瘤细胞以及NIH/3T3正常细胞的细胞毒性。化合物5h对HeLa和HUH-7细胞的生长抑制活性高于阳性对照5-氟尿嘧啶(5-FU),IC50值分别为4.5和7.7μM。有趣的是,化合物5a–r对正常细胞系没有显示出任何细胞毒性。这些结果推动了替代三唑在药物设计领域的地位,没有任何模糊性。
