Abstract

Curcumin is an inhibitor of p300 histone acetyltransferase activity, which is associated with the deterioration of heart failure. We reported that native curcumin, at a dosage of 50 mg/kg, prevented deterioration of the systolic function in rat models of heart failure. To achieve more efficient oral pharmacological therapy against heart failure by curcumin, we have developed a novel drug delivery system (DDS) which markedly increases plasma curcumin levels. At the dosage of 0.5 mg/kg, DDS curcumin but not native curcumin restored left ventricular fractional shortening in post-myocardial infarction rats. Thus, our DDS strategy will be applicable to the clinical setting in humans.
