designed, synthesized and characterized by 1H NMR, 13C NMR and HRMS. These novel synthetic compounds were evaluated for inhibitory activity against yeast α-glucosidase enzyme. The results of biological test have shown that all tested compounds exhibited excellent to potent inhibitory activity in the range of IC50 = 3.18 ± 0.12–16.59 ± 0.17 μM as compared to the standard drug acarbose (IC50 = 817.38 ± 6.27 μM)
通过1 H NMR,13 C NMR和HRMS设计,合成和表征了一系列色酮-靛红衍生物6a - 6p。评价了这些新颖的合成化合物对酵母α-葡萄糖苷酶的抑制活性。生物学测试结果表明, 与标准药物阿卡波糖(IC 50 = 817.38±6.27μM)相比,所有测试化合物在IC 50 = 3.18±0.12–16.59±0.17μM范围内均表现出优异至有效的抑制活性。化合物6j(IC 50 (= 3.18±0.12μM),在色酮的7位具有羟基,在isatin的N1位具有4-溴苄基,是该系列中活性最高的化合物。此外,进行了分子对接研究以帮助理解最活跃的类似物与α-葡萄糖苷酶的结合相互作用。这些结果表明这类化合物具有开发抗糖尿病药的潜力。
