Warburg hypothesized that the energy consumption of cancer cells is different than the normal cells. When compared to normal conditions, cancer cells do not undergo tricarboxylic acid (TCA) cycle therefore resulting in more lactate in the cells. Glycolysis pathway is a way of cancer cells to provide energy. The first step in glycolysis is the phosphorylation of glucose to glucose-6-phosphate. This reaction is catalyzed by the hexokinase-II enzyme (HK-II) which is known to be overexpressed in tumor cells. The feeding of cancer cells can be prevented by inhibiting the hexokinase-II enzyme in the first step of aerobic glycolysis. In literature, Methyl Jasmonate (MJ) is known as a Hexokinase-II inhibitor since it disposes VDAC and HK-II interaction on mitochondrial membrane. In our study, we aimed to increase the activity by synthesizing the novel MJ analogues with appropriate modifications. Here we report Hexokinase-2 enzyme and cell viability study results in different cancer cells. Based on the three different cancer cell lines we investigated, our novel MJ analogues proved to be more potent than the original molecule. Thus this research may provide more efficacious/novel HK-II inhibitors and may shed light to develop new anti-cancer agents.
瓦伯格假设癌细胞的能量消耗与正常细胞不同。与正常情况相比,癌细胞不会经历三羧酸(TCA)循环,因此细胞内会产生更多的乳酸。糖酵解途径是癌细胞提供能量的一种方式。糖酵解的第一步是将葡萄糖磷酸化为葡萄糖-6-磷酸。这个反应由己糖激酶-II 酶(HK-II)催化,该酶在肿瘤细胞中已知过度表达。通过抑制有氧糖酵解第一步中的己糖激酶-II 酶,可以阻止癌细胞的摄取。在文献中,茉莉酸甲酯(MJ)被称为己糖激酶-II 抑制剂,因为它可以在线粒体膜上处置 VDAC 和 HK-II 的相互作用。在我们的研究中,我们旨在通过合成具有适当修饰的新型 MJ 类似物来提高其活性。在这里,我们报告了己糖激酶-2 酶和不同癌细胞的细胞活力研究结果。基于我们研究的三种不同的癌细胞系,我们的新型 MJ 类似物被证明比原始分子更有效。因此,这项研究可能为 HK-II 抑制剂提供更有效的/新型抑制剂,并为开发新的抗癌药物提供启示。
