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.

We tested the hypothesis that cGMP stimulates renin release through inhibition of the cAMP-specific phosphodiesterase 3 (PDE3) in isolated rat juxtaglomerular (JG) cells. In addition, we assessed the involvement of PDE4 in JG-cell function. JG cells expressed PDE3A and PDE3B

Series of 3-substituted-9,10-dimethoxy-3,4,6,7-tetrahydro-2H-pyrimido [6,1-a]isoquinoline-2,4-diones and 2-substituted-9,10-dimethoxy-6,7-dihydro-4H-pyrimido [6,1-a]isoquinolin-4-ones were synthesized and tested for blood pressure lowering properties in anesthetized normotensive cats and conscious spontaneously hypertensive rats. Several compounds in the 2-(arylamino)-9,10-dimethoxy-6,7-dihydro-4H-pyrimido [6,1-a]isoquinolin-4-one series display a high order of activity. The most

The effect of nitric oxide (NO) on the release of bombesin-like immunoreactivity (BLI) was examined in synaptosomes of rat small intestine. The NO donor S-nitroso-N-acetylpenicillamine (SNAP; 10(-7) to 10(-4) M) significantly stimulated BLI release. In the presence of the NO

The discovery and structure-activity of a new class of renal artery phosphodiesterase inhibitors is reported, some of which are highly selective for the guanosine cyclic 3',5'-monophosphate phosphodiesterase. One of these compounds, 5,6-dihydro-8,9,11,12-tetramethoxy-1,3-dioxo-1H-benz[f]- isoquino [8,1,2- hij]quinazoline-2(3H)-carboxylic acid, ethyl ester (9), is
