5Y2O) & α-amylase enzyme (PDB: 5E0F). The docking study results revealed that pyrazole-chalcone derivatives exhibited better binding interaction to α-amylase enzyme over the DPP-4 enzyme & PPARγ. Depending on in silico experiments the designed compounds were selectively prioritized for synthesis. The synthesized compounds were subjected to enzyme-based in vitro α-amylase, DPP-4 inhibitory, and antioxidant
设计、合成了一系列吡唑-查尔酮衍生物,并对其体外α-淀粉酶和DPP-4抑制活性进行了评估。如此制备的化合物的结构通过分析和光谱技术、1H-NMR、13C-NMR和质谱来确认。为了初步研究分子靶点并确认这些抗糖尿病化合物的实验活性测试,确定了分子对接研究,使用不同的靶受体,即 DPP-4 (PDB: 2OLE)、PPARγ (PDB: 5Y2O) & α -淀粉酶(PDB:5E0F)。对接研究结果表明,吡唑-查耳酮衍生物与α-淀粉酶的结合作用优于DPP-4酶和PPARγ。根据计算机实验,设计的化合物被选择性地优先用于合成。对合成的化合物进行基于酶的体外α-淀粉酶、DPP-4 抑制和抗氧化活性。HBD、HBA、PSA、cLogP、分子量、生物利用度和药物相似性等 ADMET 参数进一步证实了这些化合物是未来研究的潜在先导化合物。化合物4d和6a对α-淀粉酶和DPP-4酶的活性最高。
