Lactate dehydrogenase A (LDH-A) is a potentially important metabolic target for the inhibition of the highly activated glycolysis pathway in cancer cells. In order to develop bifunctional compounds as inhibitor of LDH-A and anticancer agents, two pyrrol-2-yl methanone (or ethanone) derivatives (PM1 and PM2) were synthesized and evaluated as inhibitors of LDH-A based on the enzyme assay and cell assay
乳酸脱氢酶A(LDH-A)是抑制癌细胞中高度活化的糖酵解途径的潜在重要代谢靶标。为了开发作为LDH-A抑制剂和抗癌剂的双功能化合物,合成了两种吡咯-2-基甲酮(或乙酮)衍生物(PM1和PM2),并根据酶法和细胞进行了评估,作为LDH-A的抑制剂。通过光谱分析进行分析。荧光和CD光谱结果表明,LDH-A的二级结构的变化和化合物与LDH-A的亲和力相互作用均对LDH-A的活性有很大影响。特别是低浓度的化合物(1μμ-25μμ)可以改变癌细胞中丙酮酸的水平。而且,体外测定结果表明,吡咯-2-基乙酮衍生物可以抑制癌细胞的增殖。因此,吡咯-2-基乙酮衍生物(PM2)既可以作为LDH-A抑制剂,也可以作为抗癌剂。
