IBC 293 is a cell permeable Niacin triazolo derivative that is a selective agonist towards the human orphan G-protein-coupled receptor GPR109b/HM74. In addition, IBC 293 inhibits forskolin (sc-3562) and isoproterenol (sc-202188) in GPR109b-expressing CHO cells and human adipocytes. The inhibition of forskolin and isoproterenol also causes a reduction in cAMP levels in both cell lines. It has been reported that GPR 109b occurs as homodimers and heterodimers in which the extent of homo-dimerization and hetero-dimerization does not depend on ligand binding.
