Effects of DN-9693, a selective inhibitor of cyclic AMP phosphodiesterase, in isolated and perfused canine large coronary arteries.

چکیده
In isolated canine epicardial coronary arteries perfused with Krebs-Henseleit solution at 37 degrees C, DN-9693, a newly synthesized selective cyclic AMP phosphodiesterase inhibitor, induced vasodilation in a dose-related manner. The threshold dose for inducing vasodilation to DN-9693 was very small, but the maximum vasodilation was not great. The order of potency for ED20 (20% dilatation) was DN-9693 greater than IBMX greater than aminophylline, but that for ED70 was IBMX greater than aminophylline greater than DN-9693, suggesting that these three PDE inhibitors have different properties.

Alterations in EDHF-type relaxation and phosphodiesterase activity in mesenteric arteries from diabetic rats.
In isolated superior mesenteric artery rings from age-matched control rats and streptozotocin (STZ)-induced diabetic rats, we investigated the role of cAMP in endothelium-derived hyperpolarizing factor (EDHF)-type relaxation. The ACh-induced EDHF-type relaxation was significantly weaker in STZ-induced diabetic rats than in control rats, and in both groups of rats it was attenuated by 18alpha-gl...
متن کاملRegional differences of responses to adrenoceptor agonists in isolated and perfused canine coronary arteries.
Regional differences of the responses to adrenoceptor agonists were investigated in isolated canine coronary arteries by use of a cannula inserting method. Acetylcholine induced a dose-dependent vasodilation. Norepinephrine and epinephrine produced a vasoconstriction followed by a strong vasodilation in large coronary arteries and only a weak vasodilation in small coronary arteries. Phenylephri...

BACKGROUND AND PURPOSE NG-substituted analogues of L-arginine are potent and selective inhibitors of nitric oxide synthase(s). The present study was designed to determine the effects of these analogues on the vascular smooth muscle of isolated canine basilar arteries. METHODS Basilar artery rings without endothelium were suspended for isometric tension recording in Krebs-Ringer bicarbonate so...
متن کاملDissociations between changes in myocardial cyclic adenosine monophosphate and contractility.
The relationship between changes in the myocardial concentration of adenosine 3':5'-cyclic monophosphate (cyclic AMP) and cardiac contractility was studied in guinea pig and rat myocardium. When isolated perfused guinea pig heart were perfused with 10-5-M papaverine, a potent inhibitor of cyclic AMP phosphodiesterase activity, myocardial cyclic AMP concentration increased significantly from 1.7...

Background: Phosphodiesterase 3A (PDE3A) and phosphodiesterase 3B (PDE3B) play a critical role in the regulation of intracellular level of adenosine 3´,5´-cyclic monophosphate (cyclic AMP, cAMP) and guanosine 3´,5´-cyclic monophosphate (cyclic GMP, cGMP). Subsequently PDE3 inhibitors have shown to relax vascular and inhibit platelet aggregation in cardiovascular disease. Objectives: In th...
