苄氧基苯基部分是单胺氧化酶B(MAO-B),沙芬酰胺和司加吉林的高效,选择性和可逆抑制剂的常见结构。我们合成了在末端芳基单元上包含卤素取代基的4-(苄氧基)苯基和联苯-4-基衍生物。另外,我们修饰了胺基和联芳基连接单元之间的碳连接基。在合成的化合物中,12c作为竞争性抑制剂表现出最有效和选择性的MAO-B抑制作用(hMAO-B IC 50:8.9 nM;选择性比MAO-A高10,000倍)。另外,12c与著名的MAO-B抑制剂(例如司来吉兰,沙芬酰胺和sembragiline)相比,具有更高的MAO-B抑制活性和选择性。在MPTP诱发的帕金森氏病(PD)小鼠模型中,12c可显着保护酪氨酸羟化酶(TH)免疫阳性DAergic神经元,并减轻与PD相关的行为缺陷。这项研究表明,作为MAO-B抑制剂的特征结构可能为PD治疗药物的开发提供很好的见识。
