imidin-5-amine 8. The compounds were evaluated for their inhibitory in vitro enzymatic potential against α-amylase, α-glucosidase, acetylcholinesterase & proteinase. Also, the in vitro antioxidant evaluation and cytotoxicity assays were performed for all the final compounds. Interestingly, compound 8 possessed moderate activity against α-amylase (25.38 %) and α-glucosidase (29.37 %) compared to acarbose
开发针对双重/多种蛋白质的单一化合物是避免联合给药的有效方法。在此,基于先前报道的先导化合物A的修饰,我们合成了一系列新的二氢吡喃并吡唑酮7a-g和二氢吡唑并吡喃嘧啶-5-胺8。评估了这些化合物对α-淀粉酶的体外酶活性。 α-葡萄糖苷酶、乙酰胆碱酯酶和蛋白酶。此外,还对所有最终化合物进行了体外抗氧化剂评估和细胞毒性测定。有趣的是,与阿卡波糖(分别为 75.43 % 和 52.79 %)相比,化合物 8 对 α-淀粉酶(25.38 %)和 α-葡萄糖苷酶(29.37 %)具有中等活性。另一方面,与用作参考标准药物的多奈哌齐(67.28±0.61%)相比,化合物7f显示出中等的抗胆碱酯酶活性(46±0.03%抑制)。与用作参考的双氯芬酸钠(分别为47.93±0.01、44.96±0.02)相比,化合物7d表现出中等的抗关节炎活性(蛋白酶变性(42.21±0.04%)、蛋白酶抑制(38.09±0
