Quercetin-3-Oleate Contributes to Skin Wound Healing Targeting FFA1/GPR40

摘要

The hybrid molecule Quercetin-3-oleate (AV2), accommodates within the binding pocket for allosteric full GPR40 agonists. AV2 endorses skin wound healing acting as a promoter of keratinocytes proliferation and overcomes immunosuppressive conditions in vitro. AV2 stimulated HaCaT wound healing by 51% compared to the untreated control, at the concentration of 1 μM with slight TGF-β production and MMP-9 release. Pretreatment with the known GPR40 antagonist DC260126 abolished its wound healing power. Docking simulations suggested that both molecules share the same binding site.
