GLP-1R Agonist DMB (100 nM, 1000 nM) can activate GLP-1 receptor-mediated cAMP production, with an EC50 of 101 nM, but exhibits a self limiting effect at high concentrations .
GLP-1R Agonist DMB (100 nM) enhances the binding of GLP-1 to GLP-1 receptors and reduces the Kd value of GLP-1 (from 0.51 nM to 0.19 nM).
GLP-1R Agonist DMB (100 nM, 1000 nM) promotes glucose dependent insulin secretion in CD1 mouse islets, and this effect depends on the GLP-1 receptor. At concentrations of 100 nM and 1000 nM, GLP-1R Agonist DMB significantly enhances 10 mM glucose induced insulin secretion, similar to GLP-1, and this effect disappears in the islets of GLP-1 receptor knockout mice.
