Hepatocellular carcinoma (HCC) is the fifth leading cause of cancer related deaths globally. Despite advancements in treatment, drug resistance and adverse side effects have spurred the search for novel therapeutic strategies. This study aimed to investigate how the can inhibit key targets involved in HCC progression. Screening of the reported compounds based on ADMET profile and identification of protein targets was done using the literature survey. Protein targets were divided into four major categories including inflammatory, angiogenic, anti-apoptotic as well as proliferative targets. Gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analyses were performed to reveal the functional roles of genes. The STRING database was used to analyze the protein-protein interactions (PPI) of target genes. Docking was employed to predict the binding affinity of compounds with target proteins. Subsequently, MD simulation was conducted to assess the stability and dynamics of protein-ligand complexes. A total of 22 active compounds with 25 protein targets have been identified. These targets have a major role in controlling biological processes such as apoptosis, signaling and cellular interactions. KEGG pathway analysis showed that cancer, atherosclerosis, PI3K-Akt, EGFR tyrosine kinase inhibitor resistance and MAPK signaling pathways are mainly involved. Molecular docking by Mcule platform demonstrated that emblicanin A, punigluconin, penta-o-galloylglucose and quercetin showed higher binding energy affinities with BCL2, BCL2L1, c-Met, HSP70, EGFR, FGFR1, PTGS2 and TNFα. MD simulation revealed conformational changes, flexibility, interactions and compactness of protein-ligand complex. The stable protein binding interactions suggest the potential of compounds to inhibit the functions of target proteins. These results suggest that compounds derived from may have the therapeutic potential for treating HCC. See also the graphical abstract(Fig. 1).
肝细胞癌(HCC)是全球癌症相关死亡的第五大主要原因。尽管治疗取得了进展,但耐药性和不良副作用促使人们寻找新的治疗策略。本研究旨在探讨[具体内容缺失]如何抑制参与HCC进展的关键靶点。基于ADMET谱对报道的化合物进行筛选,并通过文献调研确定蛋白质靶点。蛋白质靶点分为四大类,包括炎症、血管生成、抗凋亡以及增殖靶点。进行基因本体论(GO)和京都基因与基因组百科全书(KEGG)分析以揭示基因的功能作用。利用STRING数据库分析靶基因的蛋白质-蛋白质相互作用(PPI)。采用对接技术预测化合物与靶蛋白的结合亲和力。随后,进行分子动力学(MD)模拟以评估蛋白质-配体复合物的稳定性和动力学。共鉴定出22种具有25个蛋白质靶点的活性化合物。这些靶点在控制诸如凋亡、信号传导和细胞相互作用等生物学过程中起主要作用。KEGG通路分析表明,癌症、动脉粥样硬化、PI3K-Akt、EGFR酪氨酸激酶抑制剂耐药和MAPK信号通路主要涉及其中。通过Mcule平台进行的分子对接表明,余甘子素A、punigluconin、五-O-没食子酰葡萄糖和槲皮素与BCL2、BCL2L1、c-Met、HSP70、EGFR、FGFR1、PTGS2和TNFα显示出更高的结合能亲和力。MD模拟揭示了蛋白质-配体复合物的构象变化、灵活性、相互作用和紧密性。稳定的蛋白质结合相互作用表明化合物具有抑制靶蛋白功能的潜力。这些结果表明,源自[具体内容缺失]的化合物可能具有治疗HCC的潜力。另见图1(图形摘要)。
