L-168049 is a potent, selective, orally active and non-competitive glucagon receptor antagonist with IC50s of 3.7 nM, 63 nM, and 60 nM for human, murine, and canine glucagon receptors, respectively[1][2].
L-168049 (compound 49) inhibits glucagon (100 pM) stimulated cAMP synthesis in CHO cells expressing the human glucagon receptor (hGIAR) (IC50 of 41 nM). L-168049 blocks cAMP formation stimulated by glucagon in murine liver membranes[1].
L-168049 increases the apparent EC50 for glucagon stimulation of adenylyl cyclase in Chinese hamster ovary cells expressing the human glucagon receptor and decreases the maximal glucagon stimulation observed, with a Kb of 25 nM[2].
In the liver of L-G6pc−/- mice, Pck1 mRNA expression is decreased by half 6 h after the administration of L-168049 (50 mg/kg body; p.o.), demonstrating the efficiency of the suppression of glucagon signaling. In agreement with the role of glucagon in the induction of extrahepatic gluconeogenesis, the administration of the L-168049 prevents the increase of the G6pc expression in both the kidneys and intestine of 6 h-fasted L-G6pc−/- mice[3].
