compounds were confirmed by elemental analyses, FT-IR, 1H-NMR and 13C-NMR. The antioxidant and antitumor properties of the synthesized compounds were also investigated. Three of the triazole derivatives with p-tolyl, benzyl and phenyl substituents (5c–e) displayed good antioxidant and antitumoractivity in comparison to the standards. Graphical Abstract

of serious human pathologies, such as diabetes and cancer. However, the limited availability of potent and selective inhibitors hinders the validation of this potential therapeutic target. To explore new chemotypes that target the active site of OGT, we performed virtual screening of a large library of commercially available compounds with drug-like properties. We purchased samples of the most promising
O -GlcNAcylation 是一种重要的翻译后修饰,由酶O -β- N安装-乙酰-d-氨基葡萄糖转移酶(OGT)。调节这种酶对于更好地了解其在严重的人类疾病(如糖尿病和癌症)发展中的作用非常有价值。然而,有效和选择性抑制剂的有限可用性阻碍了对这种潜在治疗靶点的验证。为了探索针对 OGT 活性位点的新化学型,我们对具有药物样特性的大型商用化合物库进行了虚拟筛选。我们购买了最有希望的虚拟命中的样本,并使用酶分析来识别真正的线索。通过生成一个小型衍生物库来探索最佳鉴定的 OGT 抑制剂的构效关系。我们的最佳作品展示了一种新型尿苷模拟支架,并用 IC 抑制了重组酶50值为 7 µM。当前的成功代表了设计和开发一组新的 OGT 抑制剂的绝佳起点,这可能证明对探索 OGT 的生物学有用。
