Abstract:
A quantitative structure-activity relationship (QSAR) study has been made on a new series of digitalis-like Na+,K+-ATPase inhibitors in which the guanylhydrazone group has been replaced by an aminoalkyloxime group. The correlations obtained have shown that the oxime moiety, primary amine group, overall size, and polarizability of the new type of substituents are higly beneficial to the Na+,K+-ATPase inhibition potency of the compounds and that their effect can be quantitatively assessed. The study also showed that the inotropic activity of the compounds is very well correlated with their Na+,K+-ATPase inhibition potency.
