imidazopyridine based oxadiazole derivatives (5a-l) were designed and synthesized. Their structures were confirmed by spectral data and then subjected to in vitro assessment including α-glucosidase, α-amylase inhibitory, and 2- diphenyl-1-picrylhydrazyl (DDPH) and 2,2′-azinobis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) radical scavenging activities. The inhibitory activity results revealed that all the
设计并合成了一系列新型咪唑并吡啶基恶二唑衍生物( 5a-l )。它们的结构通过光谱数据得到确认,然后进行体外评估,包括α-葡萄糖苷酶、α-淀粉酶抑制、2-二苯基-1-三硝基苯肼(DDPH)和2,2'-偶氮双(3-乙基苯并噻唑啉-6-磺酸)(ABTS)自由基清除活性。抑制活性结果表明,与标准阿卡波糖的IC 50 值相比,所有合成的类似物均表现出显着的α-葡萄糖苷酶和α-淀粉酶抑制作用,IC 50 值分别为0.90 ± 0.10至18.10 ± 0.20 μM(对于α-葡萄糖苷酶)和1.10 ± 0.10至19.70 ± 0.20 μM(对于α-淀粉酶) 11.50 ± 0.30μM(α-葡萄糖苷酶)和 12.20 ± 0.30 μM(对于 α-淀粉酶)。合成的类似物还表现出显着的 DPPH 和 ABTS 自由基清除活性,IC 50值范围为 1.05 ± 0.05 至 4.56 ± 3.12 μM
