2-Furoyl-LIGRLO-amide is a potent and selective proteinase-activated receptor 2 (PAR2) agonist with a pD2 value of 7.0[2]..IC50 & Target: Proteinase-activated receptor 2 (PAR2)In Vitro: 2-Furoyl-LIGRLO-amide (2-Furoyl-LIGRLO-NH2) is equally effective to and 10 to 25 times more potent than SLIGRLNH2 for increasing intracellular calcium in cultured human and rat PAR2-expressing cells, respectively.
In bioassays of tissue PAR2 activity, measured as arterial vasodilation and hyperpolarization, 2-Furoyl-LIGRLO-amide (2-Furoyl-LIGRLO-NH2) is 10 to 300 times more potent than SLIGRL-NH2. Unlike trans-cinnamoyl-LIGRLO-NH2, 2-Furoyl-LIGRLO-amide do not cause a prominent non-PAR2-mediated contraction of murine femoral arteries.In Vivo: Furoyl-LIGRLO-amide (injected intradermally at the nape of the neck; 10 μg; pre-injected) exhibits fewer scratches in response to 2-Furoyl-LIGRLO-amide but not to histamine in Trpv3-/- mice. But it decreases significantly the number of scratches in WT mice.
