TUG-499 is a selective free fatty acid receptor 1 (FFAR1 or GPR40) (Free Fatty Acid Receptor) agonist with a pEC50 of 7.39. TUG-499 exhibits >100-fold selectivity over the related receptors FFA2, FFA3, and the nuclear receptor PPARγ and other diverse receptors, ion channels, and transporters. TUG-499 can be used for the research of type 2 diabetes. TUG-499 is a click chemistry reagent, it contains an Alkyne group and can undergo copper-catalyzed azide-alkyne cycloaddition (CuAAc) with molecules containing Azide groups.
TUG-499 (compound 7) demonstrates high chemical stability, no inhibition of selected CYP enzymes or P-glycoprotein, and excellent Caco-2 permeability. TUG-499 has potent activity on recombinant human FFA1 receptors and on the rat insulinoma cell line INS-1E[1].
