The influence of prenylamine on the electrical and mechanical activity of frog atrial muscle fibers has been studied under voltage clamp conditions. At a concentration of 10-4 M, prenylamine blocks the action potential without much affecting the resting potential. The drug depresses the peak transient sodium conductance with a dissociation constant of 1.7 times 10-5 M and on a one-to-one stoichiometric basis. The curve relating peak sodium conductance to membrane potential is slightly shifted… Expand
