Antiarrhythmic drug CAS 19774-82-4 Amiodarone hydrochloride

Amiodarone is an antiarrhythmic drug for inhibition of ATP-sensitive potassium channel with IC50 of 19.1 μM. IC50 Value: 1.5 uM ( inhibit TBARS, LOOH and FPL formation)[1]in vitro: It was found that 10 uM amiodarone induces accumulation of ethidium bromide (5 ug/ml) in Saccharomyces cerevisiae cells. At the same time, in yeast cells with inactivated MDR genes, accumulation of ethidium bromide was 6-fold higher even without amiodarone. Addition of non-lethal concentrations of amiodarone to MDR-deficient cells caused an increase of intracellular ethidium bromide to the level, which was even lower than the level in amiodarone-treated wild-type cells.
