合成了一系列2-(1,3-二氧代异吲哚啉-2-基)-N-苯乙酰胺和2-(3,4-二氢异喹啉-1-基)异吲哚-1,3-二酮衍生物, 并评价了它们抑制单胺氧化酶(MAO)和胆碱酯酶(ChE)生物活性. 实验结果显示, 所有的化合物对单胺氧化酶具有一定的抑制活性. 再分别进行单胺氧化酶A (MAO-A)和单胺氧化酶B (MAO-B)抑制活性研究, 发现所有化合物对MAO-B显示比较好的抑制活性, 对MAO-A显示弱的抑制活性. 其中, 2-(1,3-二氧代异吲哚-2-基)-N-(4-氟苯基乙基)乙酰胺(2h)和2-((7-甲氧基-3,4-二氢异喹啉-1-基)甲基)异吲哚-1,3-二酮(3d)显示最好的抑制MAO-A和MAO-B作用, 对MAO的IC50值分别为(3.87±0.59)和(3.35±0.53) μmol/L. 细胞毒性实验结果显示, 抑制活性比较好的化合物对L929细胞没有细胞毒性. 化合物2h3d分子对接的结果表明, 化合物2h3d与MAO-A和MAO-B之间存在明显的相互作用. 另外, 所有的化合物对乙酰胆碱酯酶(AChE)和丁酰胆碱酯酶(BuChE)显示比较弱的抑制活性.

A series of 2-(1,3-dioxoisoindolin-2-yl)-N-phenethylacetamide and 2-(3,4-dihydroisoquinolin-1-yl)isoindole- 1,3-dione derivatives were synthesized and their biological activities of monoamine oxidase (MAO) and cholinesterase (ChE) inhibition were evaluated. The experimental results showed that all compounds exhibited certain inhibitory activity against MAOs. Upon separate monoamine oxidase A (MAO-A) and monoamine oxidase A (MAO-B) activity were studied, the compounds displayed better inhibition activity against MAO-B and weaker inhibition activity against MAO-A. Among these, 2-(1,3-dioxoisoindolin-2-yl)-N-(4-fluorophenethyl)acetamide (2h) and 2-((7-methoxy-3,4-dihydroisoquinolin-1-yl)methyl)iso- indoline-1,3-dione (3d) exhibited the most significant inhibition of MAO-A and MAO-B, with IC50 values of (3.87±0.59) and (3.35±0.53) μmol/L towards MAO, respectively. Results from cytotoxicity assays indicated that compounds with good inhi-bitory activity showed no cytotoxicity against L929 cells. Molecular docking of compounds 2h and 3d revealed significant interactions between the active analogs and amino acid residues of the protein receptors. Additionally, all compounds exhibited relatively weak inhibition activity against acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE).
