v/v)) at room temperature. The newly synthesized target molecules were characterized and confirmed through various spectral analyses such as 1H NMR, 13C NMR and HR-MS. All the target products were evaluated for their antioxidant scavenging ability through DPPH, NO, and ABTS radical methods. The molecule 7j exhibited promising antioxidant activity against DPPH scavenging with an IC50 value of 8.161 µM
Click 化学的发展导致了当代 1,2,3-三唑-噻吩并[2,3- d ]-嘧啶衍生物库的扩展,这些衍生物是通过涉及炔丙基化噻吩的 Cu 催化的 1,3-偶极环加成反应合成的[2,3- d ]-嘧啶和各种芳香族叠氮化物在室温下等比例的溶剂体系(二氯甲烷和水(1:1 v/v))。新合成的目标分子通过各种光谱分析如1 H NMR、13C NMR和HR-MS。通过DPPH、NO和ABTS自由基方法评估了所有目标产物的抗氧化清除能力。与标准药物抗坏血酸 (IC 50 = 3.073 µM)相比,分子 7j 表现出有希望的抗 DPPH 清除抗氧化活性,IC 50值为 8.161 µM 。使用构效关系 (SAR) 分析探索芳环上取代的基团的性质和位置。
