Gene Information

human ... PDE3A(5139) , PDE3B(5140)

Application

Trequinsin has been used as a PDE3 inhibitor in rat juxtaglomerular cells. This study reported that trequinsin can enhance cellular cAMP content, forskolin-induced cAMP synthesis, and renin release in cells.

Biochem/physiol Actions

Trequinsin is a strong antihypertensive agent that has a hemodynamic profile similar to that of arteriolar dilators. Trequinsin can block platelet aggregation and also inhibit tissue factor expression in human endothelial cells,.
Phosphodiesterase III inhibitor.
