What is ZAPRINAST?
Description
The cyclic nucleotide second messenger guanosine 3’5’-
Chemical properties
Zaprinast is Yellow-Orange Crystalline Powder
The Uses of ZAPRINAST
Zaprinast is a selective inhibitor of cyclic-GMP phosphodiesterase (PDE V, calmodulin insensitive). Since cGMP mediates the vasorelaxant action of nitric oxide, as well as the natriuretic and diuretic effect of at rial natriuretic factor (ANF) through the activation of PKG (cGMP dependent protein kinase), such inhibitors may display vasodilating, relaxant, and diuretic effects. These compounds may prove useful in treating hypertension and congestive heart failure.
The Uses of ZAPRINAST
cGMP phosphodiesterase inhibitor
The Uses of ZAPRINAST
Zaprinast has been used to determine its inhibitory effect on the meiosis of oocytes by germinal vesicle breakdown (GVBD) assay and to test the inhibitory effect of it on the retinal cells by immunohistochemistry.
What are the applications of Application
Zaprinast (M&B 22948) is an inhibitor of cGMP-specific phosphodiesterase
Definition
ChEBI: 5-(2-propoxyphenyl)-2,3-dihydrotriazolo[4,5-d]pyrimidin-7-one is a member of triazolopyrimidines.
Biological Activity
Phosphodiesterase inhibitor, selective for PDE6, 5, 11 and 9 (IC 50 values are 0.15, 0.76, 12.0 and 29.0 μ M respectively).
Biochem/physiol Actions
Zaprinast insubstantially inhibits phosphodiesterase 10 and 11 (PDE10 and PDE11). It also exhibits vasodilating effects.
in vitro
zaprinast is a pde5 and pde6 inhibitor with inhibiting pde9 at moderately high concentrations (29 mm) [1]. indeed, it showed that inhibition of cgmp hydrolysis by infusion of zaprinast increases the effect of anp on natriuresis with no causing deleterious drops in blood pressure. because it was known that anp receptors is localized within the glomerulus and inner medullary collecting ducts, to determine the cellular localization of pde9 enzyme in kidney will be interesting. [2]. the enzyme displayed a high specificity for cgmp with binding sites for cgmp, and a sensitivity to zaprinast similar to smooth muscle pde5, resulting in both enzymes were named cgmp-pde. however, retinal cgmp-pde was first distinguished as photoreceptor cgmp-pde with being specifically distributed in the retina and having a higher vmax and km values than other cgmp-pdes and being modulated by g protein.
