Network Pharmacology Analysis of Captopril for HypertensionIntroductionHypertension, or high blood pressure, is a common chronic disease that affects a significant portion of the global population. It is a major risk factor for cardiovascular disease, stroke, and kidney failure. Captopril is a widely prescribed medication for the treatment of hypertension. However, its underlying molecular mechanisms and potential interactions with other proteins are not fully understood. Network pharmacology analysis is a computational approach that can provide insights into the complex interactions between drugs and their targets, and aid in drug discovery and development. In this study, we aim to perform a network pharmacology analysis of Captopril to gain a better understanding of its mechanisms of action and potential protein targets.MethodsData CollectionTo perform the network pharmacology analysis, comprehensive and reliable data on drug-target interactions and disease-related proteins were collected from various databases, including DrugBank, PubChem, and STRING. The data included information on protein names, protein functions, biological pathways, and protein-protein interactions.Network ConstructionThe collected data were then used to construct a drug-target network and a protein-protein interaction network. The drug-target network represents the interactions between Captopril and its potential target proteins. The protein-protein interaction network represents the interactions between the potential target proteins themselves. Both networks were visualized using Cytoscape software.Network AnalysisSeveral network analysis tools and algorithms were applied to the constructed networks to identify key proteins and pathways involved in the pharmacological effects of Captopril. Degree centrality, betweenness centrality, and closeness centrality were calculated to assess the importance of the nodes in the networks. Gene Ontology enrichment analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis were conducted to elucidate the biological functions and pathways associated with the identified proteins.ResultsThe network analysis revealed several key proteins and pathways associated with Captopril's pharmacological effects for hypertension. Among the identified proteins, angiotensin-converting enzyme (ACE) and endothelial nitric oxide synthase (eNOS) were found to be highly connected and central nodes in the drug-target network. These proteins are known to play critical roles in the regulation of blood pressure. Additionally, proteins involved in the renin-angiotensin-aldosterone system (RAAS) pathway and the nitric oxide signaling pathway were found to be enriched, suggesting their important contributions to Captopril's effects.DiscussionThe network pharmacology analysis provided insights into the molecular mechanisms and potential protein targets of Captopril for hypertension. ACE and eNOS were identified as key proteins, indicating their potential as therapeutic targets for the treatment of hypertension. The enrichment of proteins involved in the RAAS pathway and the nitric oxide signaling pathway further supports the established roles of these pathways in blood pressure regulation. The findings of this analysis can guide future experimental studies and facilitate the development of novel therapeutic strategies for hypertension treatment.ConclusionIn this study, we employed network pharmacology analysis to investigate the mechanisms of action of Captopril for hypertension. The analysis revealed key proteins and pathways associated with Captopril's pharmacological effects and provided valuable insights into its potential protein targets. Further experimental studies are warranted to validate these findings and explore the therapeutic implications for hypertension treatment. Network pharmacology analysis holds great promise as a powerful tool in drug discovery and development, aiding in the understanding of complex drug-target interactions.
