In this study, a series of 3-benzyloxyflavone derivatives (1-10) was designed and, for the first time, evaluated for both and inhibitory activity against the β-glucosidase enzyme. The enzyme inhibitory potential of these derivatives was further assessed in an antihyperglycemic context using mechanism-based assays on -nitrophenyl-β-d-glucopyranoside (PGLT) induced diabetic models. Additionally, structure-activity relationship (SAR) was employed to identify structural features crucial for activity. Molecular docking analyses revealed that both the potent compounds and co-crystallized ligands shared similar binding orientations within the active sites of β-glucosidase (PDB IDs: 3AJ7; 66K1). Molecular dynamics (MD) simulations validated the stability of the inhibitor-enzyme complexes under physiological conditions, while density functional theory (DFT) calculations helped elucidate electronic properties critical for activity. Drug-likeness analysis was also conducted to assess the pharmacokinetic potential of the derivatives. The results highlighted several derivatives with significant inhibitory activity, desirable pharmacokinetic profiles, and promising drug-like properties, making them potential candidates for therapeutic development. The target derivatives (1-10) demonstrated strong potential as lead compounds for developing new anti-diabetic agents with effective anti-hyperglycemic properties.
在本研究中,设计了一系列3-苄氧基黄酮衍生物(1-10),并首次对其针对β-葡萄糖苷酶的抑制活性进行了评估。使用基于机制的分析方法,在对硝基苯基-β-D-吡喃葡萄糖苷(PGLT)诱导的糖尿病模型中,进一步评估了这些衍生物在抗高血糖方面的酶抑制潜力。此外,利用构效关系(SAR)来确定对活性至关重要的结构特征。分子对接分析表明,强效化合物和共结晶配体在β-葡萄糖苷酶的活性位点(PDB ID:3AJ7;66K1)内具有相似的结合取向。分子动力学(MD)模拟验证了抑制剂-酶复合物在生理条件下的稳定性,而密度泛函理论(DFT)计算有助于阐明对活性至关重要的电子性质。还进行了类药性分析,以评估衍生物的药代动力学潜力。结果突出了几种具有显著抑制活性、理想药代动力学特征和有前景的类药性质的衍生物,使其成为治疗开发的潜在候选物。目标衍生物(1-10)作为开发具有有效抗高血糖特性的新型抗糖尿病药物的先导化合物显示出强大的潜力。
