a benzyloxy substituent have been designed, synthesized and evaluated for hMAO inhibitory activity in vitro. Most of the compounds were potent and selective MAO-B inhibitors, and were weak inhibitors of MAO-A. In particular, compounds 9e (IC50 = 0.35 μM) and 10e (IC50 = 0.19 μM) were the most potent MAO-B inhibitors, and exhibited the highest selectivity for MAO-B (9e, SI > 285.7-fold and 10e, SI =
已经设计,合成并评估了一系列带有苄氧基取代基的新小分子,并对其体外hMAO抑制活性进行了评估。大多数化合物是有效的和选择性的MAO-B抑制剂,并且是MAO-A的弱抑制剂。特别是化合物9e(IC 50 = 0.35μM)和10e(IC 50 = 0.19μM)是最有效的MAO-B抑制剂,对MAO-B的选择性最高(9e,SI> 285.7倍和10e,SI = 146.8倍)。此外,MAO-B抑制的结构-活性关系表明,开放小分子中的吸电子基团更适合MAO-B抑制,并且在开放小分子的苄氧基上具有取代基,尤其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研究来解释对开放小分子的有效MAO-B抑制作用。此外,代表性化合物9e和10e在体外对SH-SY5Y细胞显示低的神经毒性。因此,带有苄氧基取代基的小分子可用于开发有望用于治疗神经退行性疾病的药物。
