Exploration of the Two-Way Adjustment Mechanism of Rhei Radix et Rhizoma for Cardiovascular Diseases

Abstract

Aim and Objective: Myocardial infarction, cerebral infarction, and other diseases caused by vascular obstruction have always jeopardized human life and health. Several reports indicate that Rhei Radix et Rhizoma has a good clinical effect in the prevention and treatment of cardiovascular diseases. Owing to the complexity of herbal medicine, the pharmacodynamic mechanism of Rhei Radix et Rhizoma is still unclear. The objectives of this study were to explore the two-way adjustment mechanism of Rhei Radix et Rhizoma and provide a new solution for the prevention and treatment of cardiovascular disease. Materials and Methods: This study used data mining, reverse pharmacophore matching, network construction, GO and KEGG Analysis, and molecular docking to investigate the two-way adjustment mechanism of Rhei Radix et Rhizoma. The methods used were based on systems pharmacology and big data analysis technology. Results: The results suggest that Rhei Radix et Rhizoma uses a two-way adjustment of activating blood circulation, as well as blood coagulation in the prevention and treatment of cardiovascular diseases. The components involved in activating blood circulation are mainly anthraquinone components. The corresponding targets are NOS2, NOS3, CALM1, and the corresponding pathways are calcium signaling pathway, VEGF signaling pathway, platelet activation, and the PI3K-Akt signaling pathway. For blood coagulation, the components are mainly tannin components; the corresponding targets are F2, F10, ELANE, and the corresponding pathways are the neuroactive ligand-receptor interaction, complement and coagulation cascades. Conclusion: This study indicated that Rhei Radix et Rhizoma exerts the two-way adjustment of activating blood circulation and blood coagulation in the prevention and treatment of cardiovascular diseases. It can make up for the side effects of the existing blood circulation drugs for cardiovascular disease, only activating blood circulation, and the uncontrollable large-area bleeding due to the long-term use of the drugs. This study provides a material basis for the development of new blood-activating drugs based on natural medicine.
