| Invitro | BETP is a GLP-1 receptor agonist, with EC50s of 0.66 and 0.755 μM for human and rat GLP-1 receptor, respectively. BETP (Compound B) is inactive in cells expressing the GLP-2, GIP, PTH, or glucagon receptors. BETP (1-10 μM) enhances insulin secretion in normal and diabetic human islets. In addition, BETP in combination with GLP-1 shows additive effects on increasing GLP-1 receptor signaling[1]. BETP increases the potency of oxyntomodulin by 10-fold (EC50 of 80 pM). GLP-1 does not change the potencies and efficacies of both oxyntomodulin and glucagon at the glucagon receptor. BETP (0-30 μM) increases the binding affinity of oxyntomodulin for the GLP-1 receptor[2]. | ||||||||||||
| In Vivo | BETP has insulinotropic effect in SD rats. BETP (10 mg/kg, jugular vein cannula) exhibits insulin secretagogue activity in the intravenous glucose tolerance test (IVGTT) model. BETP (10 mg/kg, i.v.)-treated rats need 20% higher glucose infusion rates and demonstrates higher plasma insulin levels in SD rat hyperglycemic clamp model[1]. BETP (5 mg/kg) enhances oxyntomodulin-stimulated insulin secretion[2]. | ||||||||||||
