Application

Zardaverine has been used as a phosphodiesterase inhibitor:
  • to study its effects on human colonic epithelial cells
  • to study its effects on junctional proteins in Sertoli cells
  • to study its effects on phosphodiesterase 3 A (PDE3A) expression in various tumor cells

Biochem/physiol Actions

Zardaverine is a derivative of pyridazinone. It shows anti-tumor and anti-proliferative activity in varied cell lines. Zardaverine possesses broncho-dilatory activity and exhibits therapeutic effects against asthma.
Selective inhibitor of phosphodiesterase III/IV (PDE3/4).

The cyclic AMP phosphodiesterase (PDE) III/IV inhibitor, zardaverine, and the PDE IV-selective inhibitor, rolipram, both caused concentration-dependent inhibition of opsonized zymosan-stimulated superoxide anion generation by purified human peripheral blood eosinophils with approximate IC50 values of 30 and 40 microM, respectively.

The effects of the nonselective phosphodiesterase (PDE)-inhibitor 3-isobutyl-1-methylxanthine (IBMX) and the selective PDE inhibitors SKF 94120 (type III), rolipram (type IV), zardaverine (type III/IV), and zaprinast (type V) on inherent tone in human airways were investigated. Substantial relaxation was achieved

Inhalation of aerosolized prostaglandin I(2) (PGI(2)) causes selective pulmonary vasodilation, but the effect rapidly levels off after termination of nebulization. In experimental pulmonary hypertension in intact rabbits, provoked by continuous infusion of the stable thromboxane mimetic U46619, the impact of

1. The spasmolytic and anti-spasmogenic activity of beta-adrenoceptor agonists on airways smooth muscle is thought to involve activation of the cyclic AMP/cyclic AMP-dependent protein kinase (PKA) cascade. Here we have tested the hypothesis that PKA mediates the anti-spasmogenic activity of
