A series of 13 phenyl substituted thiosemicarbazones (SB1–SB13) were synthesized and evaluated for their inhibitory potential towards human recombinant monoamine oxidase A and B (MAO-A and MAO-B, respectively) and acetylcholinesterase. The solid state structure of SB4 was ascertained by the single X-ray diffraction technique. Compounds SB5 and SB11 were potent for MAO-A (IC50 1.82 ± 0.14) and MAO-B
合成了一系列 13 种苯基取代的氨基硫脲 ( SB1-SB13 ),并评估了它们对人重组单胺氧化酶 A 和 B(分别为 MAO-A 和 MAO-B)和乙酰胆碱酯酶的抑制潜力。SB4的固态结构通过单X射线衍射技术确定。化合物SB5和SB11分别对 MAO-A (IC 50 1.82 ± 0.14) 和 MAO-B (IC 50 0.27 ± 0.015 μM) 有效。此外,SB11显示出对 MAO-B 的高选择性指数 (SI > 37.0)。氟取向的影响表明SB11 ( m-fluorine ) 对 MAO-B 的抑制活性是SB12 ( o -fluorine) 的28.2 倍。此外,SB5和SB11分别对 MAO-A 和 MAO-B 的抑制作用在可逆性实验中恢复到接近参考水平。SB5和SB11均表现出竞争性抑制模式,K i值分别为 0.97 ± 0.042 和 0.12 ± 0.006 μM。这些结果表明SB5和SB11分别是
