increased the inhibition of α-glucosidase. Compounds 2a–e exhibited a slight antioxidant effect, and compounds 3a–e a moderate antifungal activity against C. albicans (IC50 70.5–83.1 µg/mL). Docking studies revealed that compounds 2 interact with the α-glucosidase residues of the binding pocket. Therefore, these chromone derivatives may be considered as potential α-glucosidase inhibitors, as well as antifungal
合成了一系列新颖的苯甲酰基烯胺酮1a–e和2a – e和3-烷基化的发色酮3a – e,并在体外作为α-葡萄糖苷酶抑制剂以及抗氧化剂和抗真菌剂进行了评估。对白色念珠菌菌株进行了抗真菌活性测试。化合物2a和2d – e表现出对α-葡萄糖苷酶的良好抑制作用(IC 50 分别为5.5、0.9和1.5 mM),其效果优于1a – e,3a – e和阿卡波糖(标准,IC 50 = 7.73±0.9 mM)。结构-活性关系表明,色酮环系统C-3位的苯基和烯胺酮部分的4-氯苯基(衍生物2)增加了对α-葡萄糖苷酶的抑制作用。化合物2a – e表现出轻微的抗氧化作用,化合物3a – e对白色念珠菌具有中等的抗真菌活性(IC 50 70.5–83.1 µg / mL)。对接研究表明,化合物2与结合袋的α-葡萄糖苷酶残基相互作用。因此,这些色酮衍生物可被视为潜在的α-葡萄糖苷酶抑制剂,以及针对某些细菌的抗真菌剂。酵母念珠菌菌株。
