Phosphodiesterase 3 enzyme inhibitor
WebPhosphodiesterase Inhibitors. Phosphodiesterase 3 inhibitors (PDE3-Is) increase cAMP level by inhibiting its breakdown within the cell. Thus their mechanisms of action and effects on cardiac function are similar to those of β 1 -AR agonists. PDE3-Is act, however, downstream from the β 1 -AR, and thus their actions are independent from β 1 ... WebPhosphodiesterases (PDEs) are a class of enzymes that degrade cAMP and cGMP inside cells. Based on the role of cAMP and cGMP in key cellular pathways as secondary messengers, these enzymes play important roles in cell signaling (Keravis and Lugnier 2012).This enzyme class is composed of 11 families (PDE1 to PDE11), and each family …
