this rotamer orientation. In vitro calciumchannelantagonist and agonist activities were determined using guinea pig ileum longitudinal smooth muscle (GPILSM) and guinea pig left atrium (GPLA) assays, respectively. Compounds having an i-Pr ester substituent acted as dual cardioselective calciumchannel agonists (GPLA)/smooth muscle-selective calciumchannelantagonists (GPILSM), except for the C-4 3-nitro-2-pyridyl
