Milrinone (C007B-230389)

InformationMilrinone (Win 47203) is aphosphodiesterase 3 (PDE3)inhibitor, used to increase the heart's contractility.In vitroMilrinone causes a concentration-dependent increase in the cAMP level in rabbit and human platelets with similar potency. Milrinone inhibits human platelet aggregation with a median inhibitory concentration (IC50) of 2 mM.Milrinone concentration-dependently increases left ventricular developed pressure (LVDP) and contractility. Milrinone concentration-dependently increases cAMP in rabbit coronary smooth muscle cells. Milrinone increases intracellular cyclic adenosine monophosphate by inhibiting Type III phosphodiesterase. Milrinone is a potent (IC50 = 0.16-0.90 mM) and selective (100 times peak III relative to peak I) peak III inhibitor. Milrinone significant increases in cAMP content accompany significant vasorelaxation.In vivoMilrinone inhibits PDE4 in addition to PDE3 activity in the rabbit heart.Milrinone (>10 microM) causes greater elevations in intracellular cAMP and calcium than cilostazol. Milrinone causes similar increases in heart rate, cardiac output, and left ventricular +dP/dt and decreases in end-diastolic pressure and systemic vascular resistance in anaesthetized dogs. Milrinone leads to significant increases in right ventricular function as well as significant improvements in pulmonary vascular resistance, pulmonary blood flow, and left ventricular filling in mongrel dogs underwent pulmonary artery catheterization.Cell Datacell lines：Human gastric cancer cell lines MKN-28Concentrations：Incubation Time：Powder Purity:≥99%.
