these observations , coupled with the findings that bay k 8644 is a potent , competitive inhibitor of [ 3h ] nitrendipine binding to the dihydropyridine binding site in mouse brain ( ki = 7.0 x 10 ( -9 ) m ) , suggests that bay k 8644 may produce its behavioral actions via an interaction with the dhp binding site , which has been linked to the control of calcium flux across membranes in peripheral tissues .
