Free fatty acid receptor (FFAR) ligands act on G protein-coupled receptors (GPCRs) that sense fatty acids. FFAR1 and FFAR4, also called G protein-coupled receptors 40 and 120 (GPR40, GPR120), respond to medium- and long-chain fatty acids. FFAR2 and FFAR3 are GPCRs that instead bind short-chain fatty acids produced by gut bacteria. In 2003 GPR40 was shown to mediate fatty acid-stimulated insulin secretion from pancreatic beta cells. Two years later, GPR120 was linked to fatty acid-induced secretion of glucagon-like peptide 1 (GLP-1) in the gut. Fasiglifam, TUG-770 and LY2922470 are FFAR1 agonists, and GW-1100 is an FFAR1 antagonist. TUG-891 is an FFAR4 agonist, whereas GW9508 acts on both FFAR1 and FFAR4.
AP5 exhibits potent and selective agonism for the GPR40 receptor with positive allosteric modulation of endogenous ligands (AgoPAM). AP5 demonstrates a rat hIP1 EC50 of 0.49±0.28 nM against the GPR40 receptor.

3-Chloropropane-1,2-diol dipalmitate acts as a ligand for free fatty acid receptors, influencing various biological signaling pathways. This compound is primarily composed of diesters, making it relevant in studies focused on lipid metabolism and receptor activation. Research applications include investigations into metabolic disorders and the modulation of inflammatory responses through fatty acid signaling.
