Phloridzin's Diabetic Wound Healing Potential through DPP-4 Enzyme Inhibition: A Review Article.

Abstract

Diabetic wound healing is a dynamic medical process that takes place in an environment within the body that is complex and contains elevated sugar levels, oxygen deprivation, and cellular oxidative stress. Phloridzin (Phlorizin) is one of the most well-known polyphenols found in apples because of its anti-inflammatory, antioxidant, antibacterial, antidiabetic, and antiseptic properties; it can also play a significant part in the healing of diabetic wounds. The study aimed to investigate the role of phloridzin as an efficient DPP-4 inhibitor with additional therapeutic effects in diabetic wound healing, as Dipeptidyl Peptidase-4 (DPP-4) expression increases in response to increases in glucose, Reactive Oxygen Species (ROS), and inflammation. Phloridzin inhibiting DPP-4 preserves Stromal cell-derived Factor-1α (SDF-1α), Insulin-like Growth Factor (IGF), and Glucagon-like Peptide-1 (GLP-1), which are possible DPP-4 substrates involved in wound healing. The accessible material from systemic searches in PubMed, Scopus, and published articles was reviewed with no period of limitation. The in silico study showed strong binding of phloridzin with DPP-4 protein (2P8S); also, in vitro DPP-4 inhibition assay has shown better inhibition by phloridzin. This study offers new research directions for examining phloridzin's capacity to withstand oxidative stress, as well as for redefining its tactical function as a powerful DPP-4 inhibitor to regulate the process involved in the healing of diabetic wounds.
