The aim of current study was to investigate the inhibitory activities of resveratrol and taxifolin against α-amylase, α-glucosidase, and DPP-IV enzymes analysis which was further validated by studies. The analysis of molecular docking was also done to determine the binding capabilities of resveratrol and taxifolin with α-amylase, α-glucosidase, and DPP-IV enzymes. Resveratrol and taxifolin having IC values, 47.93 ± 5.21 and 45.86 ± 3.78 , respectively, showed weaker effect than acarbose (4.6 ± 1.26 ) on α-amylase but showed significant effect to inhibit α-glucosidase (32.23 ± .556 and 31.26 ± .556 , respectively). IC value of resveratrol and taxifolin (5.638 ± .0016 and 6.691 ± .004 ) in comparison to diprotin A (IC: 7.21 ± .021 ) showed that they have significant inhibitory effect on DPP-IV enzyme. Our results illustrated that resveratrol and taxifolin have potential to prevent the metabolism of carbohydrates inhibition of α-amylase and α-glucosidase, and prolongs metabolic function of incretin by inhibiting the enzymatic activity of DPP-IV. The results of molecular docking have also revealed that resveratrol and taxifolin have significant affinity to bind with α-amylase, α-glucosidase, and DPP-IV in comparison with standard drugs such as acarbose, miglitol, and diprotin.
本研究的目的是研究白藜芦醇和紫杉叶素对α-淀粉酶、α-葡萄糖苷酶和二肽基肽酶-IV(DPP-IV)的抑制活性,并通过进一步的研究进行验证。还进行了分子对接分析,以确定白藜芦醇和紫杉叶素与α-淀粉酶、α-葡萄糖苷酶和DPP-IV的结合能力。白藜芦醇和紫杉叶素的IC值分别为47.93±5.21和45.86±3.78,对α-淀粉酶的作用比阿卡波糖(4.6±1.26)弱,但对α-葡萄糖苷酶有显著抑制作用(分别为32.23±0.556和31.26±0.556)。与双丙嗪A(IC:7.21±0.021)相比,白藜芦醇和紫杉叶素的IC值(5.638±0.0016和6.691±0.004)表明它们对DPP-IV酶有显著抑制作用。我们的结果表明,白藜芦醇和紫杉叶素具有通过抑制α-淀粉酶和α-葡萄糖苷酶来预防碳水化合物代谢以及通过抑制DPP-IV的酶活性来延长肠促胰岛素代谢功能的潜力。分子对接结果还显示,与阿卡波糖、米格列醇和双丙嗪等标准药物相比,白藜芦醇和紫杉叶素与α-淀粉酶、α-葡萄糖苷酶和DPP-IV具有显著的结合亲和力。
