Monoamine oxidases (EC 1.4.3.4; MAOs), a family of FAD-containing enzymes, is an important target for antidepressant drugs. In this paper, a series of 2-phenoxyacetamide analogues were synthesized, and their inhibitory potency towards monoamine oxidases A (MAO-A) and B (MAO-B) were evaluated using enzyme and cancer cell lysate. 2-(4-Methoxyphenoxy)acetamide (compound 12) (SI = 245) and (2-(4-((prop-2-ynylimino)methyl)phenoxy)acetamide (compound 21) (IC50MAO-A = 0.018 μM, IC50MAO-B = 0.07 μM) were successfully identified as the most specific MAO-A inhibitor, and the most potent MAO-A/-B inhibitor, respectively. The inhibitory activities of these two compounds in living cells were also further evaluated utilizing HepG2 and SHSY-5Y cell lysates.
单胺氧化酶(EC 1.4.3.4;MAOs)是一类含有FAD的酶,是抗抑郁药物的重要靶点。本文中,合成了一系列2-苯氧乙酰胺类似物,并使用酶和癌细胞裂解液评估了它们对单胺氧化酶A(MAO-A)和B(MAO-B)的抑制活性。成功鉴定出2-(4-甲氧基苯氧基)乙酰胺(化合物12)(SI = 245)和2-(4-((丙-2-炔基亚氨基)甲基)苯氧基)乙酰胺(化合物21)(IC50MAO-A = 0.018 μM,IC50MAO-B = 0.07 μM)分别作为最特异的MAO-A抑制剂和最强的MAO-A/-B抑制剂。还利用HepG2和SHSY-5Y细胞裂解液进一步评估了这两种化合物在活细胞中的抑制活性。
