designed and synthesized. All newly synthesized compounds were evaluated for their a-glucosidase inhibitory activity with resveratrol as positive control in vitro. Except for 3i and 3j, all of the compounds showed a potent inhibitory activity against a-glucosidase with IC50 values in the range of 3.12 ± 1.25 to 45.95 ± 1.26 μM and the purity of these compounds was greater than 95%. The IC50 values were
设计合成了一系列(Z)-3-(2-(1,3,4-thiadiazol-2-yl)hydrazono)-1-取代的二氢吲哚-2-酮衍生物( 3a-3m )。用白藜芦醇作为体外阳性对照评估所有新合成的化合物的α-葡萄糖苷酶抑制活性。除3i和3j外,所有化合物均显示出对α-葡萄糖苷酶的有效抑制活性,IC 50值在3.12±1.25至45.95±1.26 μM范围内,这些化合物的纯度大于95%。将 IC 50值与标准白藜芦醇 (IC 50 = 22.00 ± 1.15 μM) 进行比较,发现化合物3b、3d-3h被发现比白藜芦醇更活跃。具体来说,(Z)-3-(2-(1,3,4-thiadiazol-2-yl)hydrazono)-1-(4-chlorobenzyl)indolin-2-one ( 3d ) 表现出最有效的α-葡萄糖苷酶抑制作用活性,IC 50值为 3.12 ± 1.25 μM。动力学分析表明化合物(
