Biological Activity

[Description]:

Piprofurol is a calcium channel inhibitor. Piprofurol inhibites in a concentration-dependent manner the calcium-induced contractions in isolated potassium depolarized preparations of rat aorta and relaxes the K+-induced contraction of the dog coronary artery and the rabbit basilar artery. Piprofurol exerts a negative inotropic effect on guinea-pig papillary muscle, with the EC50 of 5 μM[1].
