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

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. [ABSTRACT FROM AUTHOR]
