描述 Cyclic nucleotide phosphodiesterases (PDEs) from the human heart were separated into three isoforms, FI, FII and FIII. Milrinone has been proved to be a potent and selective inhibitor of human cardiac FIII PDE, a "low Km" enzyme for cyclic AMP (cAMP-PDE). The IC50 value for the inhibition of FIII PDE was 0.42 μM, while those of FI and FII PDEs, "high Km" enzymes, were 38 and 19 μM, respectively[3]. The concentration of milrinone that produced 50% relaxation of tracheal spirals constricted by carbachol was 3.6 × 10-5 M; The IC50 for milrinone for lung parenchymal strips contracted by histamine was 3.2 × 10-5 M; Milrinone relaxed pulmonary artery rings constricted by norepinephrine with an IC50 of 3.8 × 10-6 M[4]. Milrinone caused a concentration-dependent increase in the cAMP level in rabbit and human platelets with similar potency. Furthermore, milrinone inhibited human platelet aggregation with an IC50 of 2 μM. It was a very potent cardiotonic agent, which concentration-dependently increased left ventricular developed pressure (LVDP) and contractility as well as cAMP in rabbit coronary smooth muscle cells[5]. In rabbit heart, partial inhibition of PDE4 by milrinone contributed to greater increases in cardiomyocyte cAMP and calcium levels[6]. In mongrel dogs underwent pulmonary artery catheterization, Milrinone led to significant increases in right ventricular function as well as significant improvements in pulmonary vascular resistance, pulmonary blood flow, and left ventricular filling[7].
