Acetyldigitoxin

Acetyldigitoxin is cardiac glycoside and an inhibitor of the Na+/K+ ATPase with an IC50 value of 5 nM in isolated rat pinealocytes. This inhibition results in loss of the transmembrane Na+ gradient, which decreases activity of the Na+/Ca2+ exchanger, increasing intracellular calcium levels, inotropy, and cardiac force. Formulations containing acetyldigitoxin have been used for the treatment of heart failure and chronic atrial fibrillation.Formal Name: (3beta,5beta)-3-[(O-3-O-acetyl-2,6-dideoxy-beta-D-ribo-hexopyranosyl-(1->4)-O-2,6-dideoxy-beta-D-ribo-hexopyranosyl-(1->4)-2,6-dideoxy-beta-D-ribo-hexopyranosyl)oxy]-14-hydroxy-card-20(22)-enolide.
