Notes: Gitoxin is a cardiac glycoside originally found in Digitalis that has cardiotonic and antiarrhythmic activities.{67682,67683,67684} It inhibits Na+/K+-ATPase in an isoform-specific biphasic manner with IC50 values of 0.298 and 410 µM for the high- and low affinity human erythrocyte isoenzymes, respectively, and 1.18 and 28.5 µM for the high- and low affinity porcine cerebral cortex isoenzymes, respectively.{67683} Gitoxin increases contractility and rhythmicity in isolated guinea pig heart in a concentration-dependent manner.{67684} It is also a degradation product of the cardiac glycoside digoxin (Item No. 22266).{67685}
