carbonic anhydrase II, α-glucosidase, and urease inhibitory potential. These new chemical scaffolds showed variable efficacies against the selected enzymes. The results indicated that compounds 5b (11.8 ± 1.33 µM), 10i (83.3 ± 1.13 µM), and 10f (88.2 ± 2.27 µM) are the most active scaffolds against carbonic anhydrase II, α-glucosidase, and urease, respectively. A structure–activity relationship revealed the
与酶活性过高相关的病理状况对健康仍然是一个巨大的挑战。小分子疗法构成了规避由酶过度活跃引起的医学疾病的手段之一。在这方面,我们合成了结构多样的氨基酸杂化席夫碱(5a - 5l和10a - 10k),并对它们的碳酸酐酶II,α-葡萄糖苷酶和脲酶抑制潜力进行了评估。这些新的化学支架对选定的酶显示出不同的功效。结果表明化合物5b(11.8±1.33 µM),10i(83.3±1.13 µM)和10f(88.2±2.27 µM)分别是最有效的抗碳酸酐酶II,α-葡萄糖苷酶和脲酶的支架。构效关系揭示了构成总体活动的最结构特征。分子对接表明,这些化合物通过氢键,π-π和π-阳离子相互作用与靶标的活性位点残基具有出色的结合相互作用。
