Methionine synthase (MetS) catalyses the transfer of a methyl group from the methyltetrahydrofolate (MTHF) to homocysteine to produce methionine and tetrahydrofolate. MetS is over-expressed in the cytosol of certain breast and prostate tumor cells. In this article, we designed, synthesized, and evaluated the biological activity of a series of substituted quinoxaline derivatives that mimic the MTHF
蛋氨酸合酶(MetS)催化甲基从四氢叶酸甲酯(MTHF)到高半胱氨酸的转移,从而产生蛋氨酸和四氢叶酸。MetS在某些乳腺癌和前列腺肿瘤细胞的细胞质中过度表达。在本文中,我们设计,合成和评估了一系列在结构中模拟MTHF的取代喹喔啉衍生物的生物活性。主要目的是开发可通过阻断MTHF结合来抑制酶反应的抑制剂。这些抑制剂以与MTHF在其结合结构域中相同的方式对接到MTHF结合结构域中。化合物4-(((6-硝基-喹喔啉-2-基)甲基氨基}甲基)苯甲酸显示出最低的结合自由能(-152.62 kJ / mol),并显示出最低的IC 50 分别针对两种类型的癌细胞系PC-3和MCF-7的45±9和53±9μM值。
