HMG–CoA reductase inhibition mediated hypocholesterolemic potential of myricetin and quercetin: in-silico and in-vivo studies

Abstract

The study was aimed to examine the HMG-CoA reductase (HMGCR) inhibition potential. The in-silico investigations followed the assessments of molecular docking, druggability and molecular dynamics. The molecular dynamics was performed at 100 ns by calculating interaction free energies, RSMD, RSMF, radius of gyration and SASA. Consequently, in-vivo examinations were performed by using a hypercholesterolemic rabbit animal model. The molecular docking showed significant interaction capabilities of myricetin as revealed by binding energy data up to −8.4 Kcal/mol. Accordingly, the data of molecular dynamics i.e. free energy, solvation free energy, radius of gyration, RSMD, RSMF and SASA were shown significant interaction capabilities of myricetin with HMGCR. Supportively, significant ameliorations were made in lipid profile, dyslipidemia indices and oxidative stress by the treatments of myricetin compared to quercetin and atorvastatin. Thus, it can be concluded that myricetin is a potent flavanol with significant potential for HMGCR inhibition and free radical scavenging capability.
