Insulin secretion stimulated by both 200 mu M tolbutamide and 20 mu M gliclazide , concentrations that had equivalent effects on membrane potential , was inhibited by thapsigargin ( 1 mu M ) or the L - type Ca ( 2 + ) channel blocker nicardipine ( 2 mu M ) and was potentiated by 8 - pCPT - 2 ' - O - Me - cAMP - AM at concentrations >= 2 mu M in INS - 1 cells .
 tolbutamide, gliclazide, thapsigargin, Ca ( 2 + ), nicardipine, 8 - pCPT - 2 ' - O - Me - cAMP - AM
