Abstract

Erectile dysfunction in men may result as a side effect of the use of serotonin reuptake inhibitors such as paroxetine. Enzymes like phosphodiesterase 5 (PDE-5) and arginase are promising therapeutic targets for managing erectile dysfunction while creatinine kinase-myocardial band (CK-MB) serves as a marker for coronary artery disease. To manage these conditions, it is necessary to seek options in medicinal herbs. Rauwolfia vomitoria (RV) is a plant that has been used as an aphrodisiac but the inhibitory mechanism against these enzymes remain unclear. The study used in-vivo enzymatic biomarkers and molecular docking approach to better understand their inhibitory mechanism. Forty-eight adult male Wistar rats were divided into six groups of eight rats: naive control, paroxetine (PXT, 10 mg/kg), PXT+sildenafil citrate (4 mg/kg), PXT + RVE (12.5, 25 and 50 mg/kg). Exposure to PXT lasted for twenty-one days, and treatment with sildenafil citrate and RVE took place for the next seven days. On day twenty-nine, the rats were sacrificed under anaesthesia and various biochemical assays (PDE-5, Arginase, nitric oxide (NO) were carried out on penile tissue homogenate while CK-MB, lipid profile and testosterone were assayed in the serum of rats. This study also employed gas chromatography -flame ionization detection (GC-FID) to identify the phytoconstituents in RV. From our findings, PXT significantly increased PDE-5, Arginase activities with a concomitant decrease in NO concentration. Rauwolfia vomitoria extract (RVE) decreased the activities of the penile PDE 5 and arginase activities, and increased NO concentrations in dose-dependent ways (12.5, 25, and 50 mg/kg body weight). RVE showed an increase in testosterone and a decrease in CK-MB activities. Moreover, the result of lipid profile revealed the significant reversal of the changes caused by PXT administration, indicating the potential of the extract in ameliorating paroxetine-induced dyslipidemia. All of the phytochemicals found by GC-FID docked against PDE-5 had the lowest binding energies ( - 9.4 to -7.0 kcal/mol) when likened to that of sildenafil citrate ( - 7.4 kcal/mol). The phytochemicals were also docked against arginase which released the lowest binding energy between -10.5 and -9.0 kcal/mol when compared with sildenafil citrate ( - 9.4 kcal/mol). This study is relevant in the design of new treatment option for ED and coronary artery disease.

期刊介绍: Cell Biochemistry and Biophysics (CBB) aims to publish papers on the nature of the biochemical and biophysical mechanisms underlying the structure, control and function of cellular systems The reports should be within the framework of modern biochemistry and chemistry, biophysics and cell physiology, physics and engineering, molecular and structural biology. The relationship between molecular structure and function under investigation is emphasized. Examples of subject areas that CBB publishes are: · biochemical and biophysical aspects of cell structure and function; · interactions of cells and their molecular/macromolecular constituents; · innovative developments in genetic and biomolecular engineering; · computer-based analysis of tissues, cells, cell networks, organelles, and molecular/macromolecular assemblies; · photometric, spectroscopic, microscopic, mechanical, and electrical methodologies/techniques in analytical cytology, cytometry and innovative instrument design For articles that focus on computational aspects, authors should be clear about which docking and molecular dynamics algorithms or software packages are being used as well as details on the system parameterization, simulations conditions etc. In addition, docking calculations (virtual screening, QSAR, etc.) should be validated either by experimental studies or one or more reliable theoretical cross-validation methods.
