the compounds were screened for their α-amylase inhibitory and free radical scavenging activities by DPPH (1,1-diphenyl-2-picrylhydrazyl) and ABTS methods. Among the tested compounds, compound 8g emerged as a promising α-amylase inhibitor with IC50 = 0.76 ± 1.23 µM, and it was found to be more potent than the standard drug acarbose (IC50 = 0.86 ± 0.81 μM). Compounds 8b and 8g showed strong free radical
作为我们鉴定有效 α-淀粉酶抑制剂的一部分,在本研究中,通过 3-(芳基/苄氧基芳基)-吡唑-4-甲醛与氟化 2 的缩合制备了一系列新型氟化噻唑烷酮-吡唑杂化分子。 ,3-二取代噻唑烷-4-酮。新合成化合物的结构通过红外、1 H 核磁共振 (NMR)、13 C NMR 和液相色谱-质谱数据证实。通过 DPPH (1,1-diphenyl-2-picrylhydrazyl) 和 ABTS 方法筛选所有化合物的 α-淀粉酶抑制和自由基清除活性。在测试的化合物中,化合物8g成为一种有前途的 α-淀粉酶抑制剂,IC 50 = 0.76 ± 1.23 µM,并且被发现比标准药物阿卡波糖更有效(IC 50 = 0.86 ± 0.81 µM)。与标准丁基化羟基苯甲醚相比,化合物8b和8g显示出较强的自由基清除活性。化合物8g的动力学研究揭示了对 α-淀粉酶的可逆的、经典的竞争性抑制模式。对最有效的化合
