To obtain α-glucosidase inhibitors with high activity, 19 NB-DNJDs (N-benzyl-deoxynojirimycin derivatives) were designed and synthesized. The results indicated that the 19 NB-DNJDs displayed different inhibitory activities towards α-glucosidase in vitro. Compound 18a (1-(4-hydroxy-3-methoxybenzyl)-2-(hydroxymethyl) piperidine-3,4,5-triol) showed the highest activity, with an IC50 value of 0.207 ± 0
为了获得高活性的α-葡萄糖苷酶抑制剂,设计并合成了19种NB-DNJD(N-苄基-脱氧野尻霉素衍生物)。结果表明,19种NB-DNJDs在体外对α-葡萄糖苷酶表现出不同的抑制活性。化合物 18a(1-(4-羟基-3-甲氧基苄基)-2-(羟甲基)哌啶-3,4,5-三醇)表现出最高的活性,IC50 值为 0.207 ± 0.11 mM,其次是 18b(1 -(3-溴-4-羟基-5-甲氧基苄基)-2-(羟甲基)哌啶-3,4,5-三醇,IC50:0.276 ± 0.13 mM)。18a 和 18b 的 IC50 值均显着低于阿卡波糖 (IC50: 0.353 ± 0.09 mM)。根据构效分析,苯环上的苄基和溴基团的取代降低了抑制活性,而甲氧基和羟基的取代增加了活性,尤其是羟基取代。分子对接结果表明,化合物18a与α-葡萄糖苷酶活性位点的氨基酸形成了三个氢键。此外,还模拟了化合物 18a 的苯环和
