Protein kinase A is responsible for activation of lipase, which induces lipolysis as well as other physiological pathways. [ 6 ] [ 4 ] Whether phosphorylation pathways, which regulate activity of PDE3A or PDE3B, could serve as potential drug targets rather than the catalytic domain of the PDE3 enzyme itself is unclear and beyond the scope of ...
Milrinone, sold under the brand name Primacor, is a pulmonary vasodilator [2] used in patients who have heart failure. It is a phosphodiesterase 3 inhibitor that works to increase the heart's contractility and decrease pulmonary vascular resistance.
Amrinone, milrinone and enoximone are used clinically for short-term treatment of cardiac failure in the presence of cardiogenic shock. [1]PDE3 inhibitors are indicated as inotropics for the therapy of acute heart failure if catecholamines are ineffective. [2]
Cardiac glycosides like digoxin, primarily inhibit the sodium-potassium pump (Na+/K+ ATPase), an important protein located on the surface of cardiomyocytes (cardiac muscle cells). [ 1 ] [ 2 ] Using ATP (the cell’s energy currency), this protein facilitates the transport of extracellular potassium ions (K+) into the cell while exporting sodium ...
Vasodilation plays a major role in immune system function. Wider blood vessels allow more blood containing immune cells and proteins to reach the infection site. Vasodilation occurs as part of the process of inflammation, which is caused by several factors including presence of a pathogen, injury to tissues or blood vessels, and immune ...
At the top level are all alpha proteins (domains consisting of alpha helices), all beta proteins (domains consisting of beta sheets), and mixed alpha helix/beta sheet proteins. While most proteins adopt a single stable fold, a few proteins can rapidly interconvert between one or more folds. These are referred to as metamorphic proteins. [5]

Amrinone decreases the pulmonary capillary wedge pressure while increasing cardiac output, as it functions as an arterial vasodilator and increases venous capacitance while decreasing venous return. [5] There is a net decrease in myocardial wall tension, and O 2 consumption when using amrinone.
