This study presents a comparative analysis of molecular docking data, focusing on the binding interactions of the natural compounds apigenin and luteolin with the proteins TP-53, pRb, and APOBEC, in comparison to conventional pharmacological ligands. Advanced bioinformatics techniques were employed to evaluate and contrast binding energies, showing that apigenin and luteolin demonstrate significantly higher affinities for TP-53, pRb, and APOBEC, with binding energies of -6.9 kcal/mol and -6.6 kcal/mol, respectively. These values suggest strong potential for therapeutic intervention against HPV-16. Conventional ligands, by comparison, exhibited lower affinities, with energies ranging from -4.5 to -5.5 kcal/mol. Additionally, protein-protein docking simulations were performed to assess the interaction between HPV-16 E6 oncoprotein and tumor suppressors TP-53 and pRb, which revealed high binding energies around -976.7 kcal/mol, indicative of their complex interaction. A conversion formula was applied to translate these protein-protein interaction energies to a comparable scale for non-protein interactions, further underscoring the superior binding potential of apigenin and luteolin. These findings highlight the therapeutic promise of these natural compounds in preventing HPV-16-induced oncogenesis, warranting further experimental validation for clinical applications.
本研究对分子对接数据进行了比较分析,重点关注天然化合物芹菜素和木犀草素与蛋白质TP-53、pRb和载脂蛋白B编辑酶催化多肽样蛋白(APOBEC)的结合相互作用,并与传统药理配体进行比较。采用先进的生物信息学技术来评估和对比结合能,结果表明芹菜素和木犀草素对TP-53、pRb和APOBEC表现出显著更高的亲和力,结合能分别为-6.9千卡/摩尔和-6.6千卡/摩尔。这些数值表明针对人乳头瘤病毒16型(HPV-16)进行治疗干预具有很大潜力。相比之下,传统配体的亲和力较低,能量范围在-4.5至-5.5千卡/摩尔之间。此外,还进行了蛋白质-蛋白质对接模拟,以评估HPV-16 E6癌蛋白与肿瘤抑制因子TP-53和pRb之间的相互作用,结果显示结合能在-976.7千卡/摩尔左右,表明它们之间存在复杂的相互作用。应用一个转换公式将这些蛋白质-蛋白质相互作用能转换为与非蛋白质相互作用可比的尺度,进一步突出了芹菜素和木犀草素的优越结合潜力。这些发现凸显了这些天然化合物在预防HPV-16诱导的肿瘤发生方面的治疗前景,值得进一步进行实验验证以用于临床应用。
