Urotensin II (114-124), human, is an 11-amino acid residue peptide that exhibits strong vasoconstrictor activity and acts as an agonist for the orphan receptor GPR14.

Urotensin-II (UT) receptor pure antagonist (pEC50 = 7.24). Displays no agonist activity unlike other U-II/URP analogs. Inhibits the action of U-II in the rat aorta ring assay.

GSK706 is a novel effective agonist of the GPR119.

Firuglipel is an orally available and selective agonist of GPR119.

FFA2 allosteric agonist. Inhibits forskolin-induced cAMP increase and stimulates 35SGTPγS binding in biochemical assays (pEC50 values are 6.9 and 7.23, respectively). Binds at allosteric binding site. In functional assays, displays positive allosteric modulation of FFA-induced Gi signaling and negative allosteric modulation of FFA-induced Gq/G11 signaling. Inhibits lipolytic effect of isoproterenol (pEC50 = 5.03) and induces migration of human neutrophils in vitro.
