To investigate the mechanism of professor Fu Deyu’s core prescription, Danyu Hemai Granules (DYHMG), in treating hypertension using network pharmacology, and to conduct preliminary validation through molecular docking technology.
Active components and targets of Danyu Hemai Granules were screened with traditional Chinese medicine systems pharmacology database and analysis platform (TCMSP), traditional Chinese medicine integrated database (TCMID), and HERB database. Hypertension-related targets were retrieved from GeneCards and OMIM. Intersection targets were identified, and protein-protein interaction (PPI) networks were constructed via STRING. The "Herb-Active Component-Target-Disease" network was visualized using Cytoscape to identify core targets. GO and KEGG pathway enrichment analyses were performed with Metascape. Finally, molecular docking validation was performed between key active components and core targets.
A total of 127 active ingredients and 312 targets of DYHMG, and 5 251 hypertension-related targets were identified, resulting in 229 common targets. Analysis suggested DYHMG exerts its antihypertensive effects primarily through active ingredients such as quercetin, kaempferol, luteolin, beta-sitosterol, stigmasterol, and wogonin. These ingredients acted on core targets including signal transducer and activator of transcription 3 (STAT3), RAC-alpha serine/threonine-protein kinase (AKT1), and estrogen receptor alpha (ESR1). Key pathways involved were lipid and atherosclerosis, the HIF-1 signaling pathway, insulin resistance, calcium signaling pathway, cAMP signaling pathway, MAPK signaling pathway, necroptosis, the renin-angiotensin system (RAS), and efferocytosis pathways.
Danyu Hemai Granules exhibits the characteristics of multi-component, multi-target, and multi-pathway in the treatment of hypertension. This study can provide ideas for the in-depth research on Danyu Hemai Granules in the treatment of hypertension and offer a scientific basis for its rational clinical application.
