Globally, cancer is the second leading cause of mortality and morbidity. The growth and development of cancer are extremely complex. It is caused by a variety of pathways and involves various types of enzymes. Pyruvate kinase M2 (PKM2) is an isoform of pyruvate kinase, that catalyses the last steps of glycolysis to produce energy. PKM2 is relatively more expressed in tumour cells where it tends to exist in a dimer form. Various medicinal plants are available that contain a variety of micronutrients to combat against different cancers. The phytocompounds of the olive tree ( leaves play an important role in inhibiting the proliferation of several cancers. In this study, the phytocompounds of olive leaf extract (OLE) were studied using various in silico tools, such as pkCSM software to predict ADMET properties and PASS Online software to predict anticancer activity. However, the molecular docking study provided the binding energies and inhibition constant and confirmed the interaction between PKM2 and the ligands. The dynamic behaviour, conformational changes, and stability between PKM2 and the top three hit compounds (Verbascoside (Ver), Rutin (Rut), and Luteolin_7__glucoside (Lut)) are studied by MD simulations.
在全球范围内,癌症是第二大致死和致残原因。癌症的生长和发展极其复杂。它是由多种途径引起的,涉及各种类型的酶。丙酮酸激酶 M2 (PKM2) 是丙酮酸激酶的同工酶,它催化糖酵解的最后几步以产生能量。PKM2 在肿瘤细胞中表达相对较高,在那里它倾向于以二聚体形式存在。有许多药用植物含有多种微量营养素,可用于对抗各种癌症。橄榄树的植物化合物(叶子)在抑制多种癌症的增殖方面发挥着重要作用。在这项研究中,使用各种计算工具,如 pkCSM 软件来预测 ADMET 特性和 PASS Online 软件来预测抗癌活性,研究了橄榄油提取物(OLE)的植物化合物。然而,分子对接研究提供了结合能和抑制常数,并证实了 PKM2 与配体之间的相互作用。通过 MD 模拟研究了 PKM2 与前三种命中化合物(毛蕊花糖苷(Ver)、芦丁(Rut)和木犀草素_7__葡萄糖苷(Lut))之间的动态行为、构象变化和稳定性。
