was the most effective in inhibiting MAO-B, followed by compound BB2 (IC50 = 0.093 μM). The lead molecules showed good activity than the reference MAO-B inhibitors (Lazabemide IC50 = 0.11 μM and Pargyline Pargyline IC50 = 0.14). The high selectivity index (SI) values for MAO-B were observed in compounds BB2 and BB4 (430.108 and 645.161, respectively). Kinetics and reversibility experiments revealed that
合成了八种苄氧基衍生的卤代查耳酮衍生物 ( BB1-BB8 ),并测试了它们抑制单胺氧化酶 (MAO) 的能力。所有化合物对 MAO-A 的抑制效率均低于 MAO-B。此外,大多数化合物在 1 μM 时表现出显着的 MAO-B 抑制活性,残留活性低于 50%。化合物BB4抑制MAO-B的IC 50值为0.062 μM ,其次是化合物BB2 (IC 50 = 0.093 μM)。先导分子比参考 MAO-B 抑制剂(Lazabemide IC 50 = 0.11 μM 和 Pargyline Pargyline IC 50)表现出良好的活性 = 0.14)。在化合物BB2和BB4中观察到 MAO-B 的高选择性指数 (SI) 值(分别为 430.108 和 645.161)。动力学和可逆性实验表明,BB2和BB4是可逆竞争性 MAO-B 抑制剂,K i值分别为 0.030 ± 0.014 和
