Monoamine oxidase B (MAO-B) is a flavin adenine dinucleotide (FAD)-containing enzyme that plays a major role in the oxidative deamination of biogenic amines and neurotransmitters. Inhibiting MAO-B activity is a promising approach in the treatment of neurological disorders. Here, we report a series of 2-aryl-1,3,4-oxadiazin-5(6H)-one derivatives as highly selective and potent MAO-B inhibitors. Analysis
单胺氧化酶B(MAO-B)是一种含有黄素腺嘌呤二核苷酸(FAD)的酶,在生物胺和神经递质的氧化脱氨中起主要作用。抑制MAO-B活性是治疗神经系统疾病的一种有前途的方法。在这里,我们报告一系列的2-芳基-1,3,4-恶二嗪-5(6H)-一衍生物作为高选择性和有效的MAO-B抑制剂。对hMAO-A和hMAO-B结合位点的分析导致设计带有额外苯环的2-芳基-1,3,4-恶二嗪-5(6H)-one的线性类似物。通过对26种新衍生物的生物学评估,鉴定出了具有最佳理化特性的强效和选择性抑制剂,这些抑制剂有可能跨越血脑屏障(BBB)。化合物18a,18b,18e和25b有效抑制MAO-B,IC50值为4-25 nM,优于MAO-A的SI(18a> 25000、18b> 8333和18e> 4000和25b> 4545)。对接结果表明,在2-芳基-1,3,4-恶二嗪-5(6H)-一个支架上的两个芳香环之间
