series of acetophenone derivatives have been designed, synthesized and evaluated for human monoamine oxidase A and B inhibitory activity in vitro. Most of the tested compounds acted preferentially on MAO-B with IC50 values in the nanomolar range and weak or no inhibition of MAO-A. In particular, compounds 1j (IC50 = 12.9 nM) and 2e (IC50 = 11.7 nM) were the most potent MAO-B inhibitors being 2.76- and 2
已经设计,合成和评估了两个系列的苯乙酮衍生物在体外对人单胺氧化酶A和B的抑制活性。大多数测试的化合物优先以30纳摩尔范围的IC 50值对MAO-B起作用,对MAO-A的抑制作用弱或无抑制作用。特别是化合物1j(IC 50 = 12.9 nM)和2e(IC 50= 11.7 nM)是最有效的MAO-B抑制剂,其活性比司来吉兰高2.76倍和2.99倍。此外,MAO-B抑制的结构-活性关系表明,苯乙酮部分C3和C4处的取代基,特别是被卤素取代的苄氧基取代,对MAO-B抑制更有利。已经进行了分子对接和动力学研究以解释MAO-B与苯乙酮衍生物的结合模式。此外,代表性化合物1j和2e在SH-SY5Y细胞中显示出低神经毒性。可以得出结论,苯乙酮衍生物可用于开发有望用于治疗神经退行性疾病的先导化合物。
