Lovastatin and Resveratrol Synergistically Improve Wound Healing and Inhibit Bacterial Growth

Wound healing is a complex physiological process, with scarring and infection caused by Staphylococcus aureus and Pseudomonas aeruginosa being the most common complications. The reutilization of known medications has received increased attention for their role in cell function as small molecules. Examples of these include lovastatin, a cholesterol-lowering agent, and resveratrol, which have multiple biological properties. Both molecules have been reported to improve wound healing and possess antibacterial properties, with conflicting results. The wound-healing capabilities of human mesenchymal stem cells were evaluated after exposure to lovastatin, resveratrol, and their combination through scratch test, migrations assay, and qPCR. Protein docking was performed to assess the lovastatin/resveratrol combination as potential wound-healing targets. AlamarBlue assay was used to determine cell viability. Additionally, the impact of lovastatin and resveratrol combination to inhibit the growth of S. aureus and P. aeruginosa was tested using broth microdilution test and checkerboard assay to determine synergism. The combination of lovastatin 0.1 μM and resveratrol 0.1 μM synergistically improved wound healing and demonstrated an additive effect against S. aureus and P. aeruginosa, presenting potential antibacterial applications.
