Tiger17, a cyclic peptide derivative of tigerinin-RC1 and tigerinin-RC2—antimicrobial peptides from the crab-eating frog (F. cancrivora) skin secretions—enhances HaCaT keratinocytes and human skin fibroblasts proliferation at 5 to 20 µg/ml concentrations, and promotes HaCaT cell migration at 20 µg/ml. Additionally, Tiger17 augments RAW 264.7 macrophages' recruitment and secretion of TGF-β1 and IL-6. When topically applied at 20 µg/ml, it accelerates wound closure and re-epithelialization in a mouse model of full-thickness dermal wounds.
