Parkinson’s disease (PD), there is still a vital need to develop novel selective monoamine oxidase B (MAO-B) inhibitors as promising therapeutically active candidates for PD patients. Herein, we report the design, synthesis, and full characterization of new twenty-six indole derivatives as potential human MAO-B (hMAO-B) selective inhibitors. Six compounds (2i, 3b–e, and 5) exhibited low micromolar to
由于尚未发现帕金森病 (PD) 的疾病改善疗法,因此仍然迫切需要开发新型选择性单胺氧化酶 B (MAO-B) 抑制剂作为 PD 患者的有希望的治疗活性候选物。在此,我们报告了作为潜在的人类 MAO-B ( h MAO-B) 选择性抑制剂的新 26 种吲哚衍生物的设计、合成和完整表征。六种化合物(2i、3b - e和5)对h MAO-B表现出低微摩尔至纳摩尔的抑制活性;与我们最近报道的基于N-取代吲哚的先导化合物VIII ( h MAO-B IC50 = 777 nM),化合物5 (3,4-二氯-N -(1 H-吲哚-5-基)苯甲酰胺)表现出 18 倍的效力增加 (IC 50 = 42 nM)。对h MAO- A 的选择性研究揭示了化合物5的出色选择性指数(SI > 2375),与雷沙吉兰(II,一种众所周知的 MAO-B 抑制剂,SI > 50)相比增加了 47 倍。化合物5对h MA
