Agents used for the treatment or prevention of cardiac arrhythmias. They may affect the polarization-repolarization phase of the action potential, its excitability or refractoriness, or impulse conduction or membrane responsiveness within cardiac fibers. Anti-arrhythmia agents are often classed into four main groups according to their mechanism of action: sodium channel blockade, beta-adrenergic blockade, repolarization prolongation, or calcium channel blockade.
Agents that have a strengthening effect on the heart or that can increase cardiac output. They may be CARDIAC GLYCOSIDES; SYMPATHOMIMETICS; or other drugs. They are used after MYOCARDIAL INFARCT; CARDIAC SURGICAL PROCEDURES; in SHOCK; or in congestive heart failure (HEART FAILURE).
Compounds or agents that combine with an enzyme in such a manner as to prevent the normal substrate-enzyme combination and the catalytic reaction.

説明Digitoxin is the most powerful and reliable of the glucosides which have been extracted from digitalis leave. It is a cardiac glycoside (CG). It is a cardiotonic drug, which exhibits cardiac and anti-cancer properties. Digitoxin inhibits nuclear factor kappa B (NF-κB) signaling. It is used to treat congestive heart failure and cardiac arrhythmia. Digitoxin prevents microtubule formation.
使用Digitoxin has been used as a labeled drugs for binding sites on human serum albumin (HSA). It has also been used to test its anti-transmissible gastroenteritis virus (TGEV) activity.
一般的な説明Odorless white or pale buff microcrystalline powder. Used as a cardiotonic drug.

純化方法Digitoxin crystallises from MeOH, aqueous EtOH with 0.5 to 1 H2O and from H2O as the dihydrate. It also crystallises from CHCl3/Et2O as anhydrous crystals. The hydrate dehydrates at 120o/vacuum. Its solubility is 2.5% in CHCl3, 1.7% in EtOH, 0.25% in EtOAc, and 0.001% in H2O; and has E1cm 202.5 at 219-220nm (50% EtOH). [Stoll et al.
