CAS:Controlled ProductDideiodo amiodarone is a noncompetitive inhibitor of the enzyme, which is expressed in the human heart. It has been shown to interact with the benzofuran derivatives that are responsible for the antiarrhythmic effects of amiodarone. The inhibitory potency of dideiodo amiodarone is dose-dependent and constant. This drug has shown no competitive inhibition against any other analogs, such as quinidine or digitoxin. Dideiodo amiodarone inhibits the enzyme by binding to an allosteric site on the enzyme molecule. This site does not bind any other analogs, such as quinidine or digitoxin, and therefore it does not compete for this site.Formula:C25H31NO3Purity:Min. 95%Color and Shape:Clear LiquidMolecular weight:393.52 g/molEtonogestrel Impurity 10
