TCS 2510 (0.001~100 μM; GLUTag cells) stimulates glucagon like peptide 1 secretion. TCS2510 activates the Gas signaling pathway. TCS 2510 (10 μM; 2~24 h; GLUTag cells) increases the Gcg mRNA expression levels. TCS 2510 produces a concentration dependent increase in cAMP levels in GLUTag cells with EC50 of 20 nM and the maximal stimulation of 60 % over the basal cAMP levels. The decrease in cell impedance in GLUTag cells observed with TCS 2510 is concentration dependent with IC50 of 15 nM. TCS 2510 produces a concentration-dependent increase in glucagon like peptide 2 secretion in GLUTag cells.
