4-position of the right phenyl and 2-fluorobenzyl substituent at the N1-positions of the 5-methylisatin displayed the highest inhibitory activity with an IC50 value of 5.36 ± 0.13 μm. Molecular docking studies revealed the existence of hydrophobic interaction, CH-π interaction, arene-anion interaction, arene-cation interaction, and hydrogen bond between these compounds and α-glucosidase enzyme.
合成了一系列新的靛红-噻唑衍生物并筛选了它们的体外 α-葡萄糖苷酶抑制活性。与标准药物阿卡波糖 (IC50 = 817.38 ± 6.27 μm) 相比,这些化合物显示出不同程度的 α-葡萄糖苷酶抑制活性,IC50 范围为 5.36 ± 0.13 至 35.76 ± 0.31 μm。在该系列中,化合物6p在右苯基的4-位带有羟基,在5-甲基靛红的N1-位带有2-氟苄基取代基,显示出最高的抑制活性,IC50值为5.36±0.13 μm。分子对接研究揭示了这些化合物与α-葡萄糖苷酶之间存在疏水相互作用、CH-π相互作用、芳烃-阴离子相互作用、芳烃-阳离子相互作用以及氢键。
