Phosphodiesterase inhibitors in airways disease
European Journal of Pharmacology, 2006Phosphodiesterases hydrolyse intracellular cyclic nucleotides, cyclic adenosine monophosphate (cAMP) and cyclic guanosine monophosphate (cGMP) into inactive 5' monophosphates, and exist as 11 families. They are found in a variety of inflammatory and structural cells.

Disaggregatory action of phosphodiesterase inhibitors
Pharmacological Research Communications, 1981Summary Papaverine and three hypotensive xanthines were shown to disaggregate platelet clumps in anaesthetized cats. The order of disaggregatory potency was: IMBX > papaverine > > aminophylline ≫ xantinol nicotinate. This effect was not associated with the release of prostacyclin. It is concluded that disaggregatory action of papaverine and xanthines

Phosphodiesterase Inhibitors and Cerebral Vasospasm
Archives of Neurology, 1975Experimental cerebral vasospasm was studied in cat and monkey models. In the cat, the basilar artery was exposed by a transclival approach and spasm induced by the application of blood to the vessel. In the monkey, spasm was produced by injecting blood into the subarachnoid space.

Inhibitors of phosphodiesterase as cancer therapeutics
European Journal of Medicinal Chemistry, 2018Phosphodiesterases (PDEs) are a class of enzymes that hydrolyze cyclic adenosine monophosphate (cAMP) and cyclic guanosine monophosphate (cGMP) which is involved in many physiological processes including visual transduction, cell proliferation and differentiation, cell-cycle regulation, gene expression, inflammation, apoptosis, and metabolic function ...

[Phosphodiesterase inhibitors].
Annales de cardiologie et d'angeiologie, 1991Phosphodiesterase III inhibitors constitute a new therapeutic group for congestive cardiac failure. They inhibit the degradation of cyclic adenosine monophosphate and increase the intracellular calcium. They have a double inotropic and vasodilator haemodynamics occurs without any increase in the myocardial effect.

The role of phosphodiesterase inhibitors in impotence
Expert Opinion on Investigational Drugs, 1997Penile erection is mediated by nitric oxide (NO) and its second messenger cyclic guanosine monophosphate (cGMP). The activity of cGMP is modulated by the enzyme phosphodiesterase (PDE). The most important physiological isoform of the enzyme in the penis is PDE5.

Targeting cancer with phosphodiesterase inhibitors
Expert Opinion on Investigational Drugs, 2009For many cancers, there has been a shift from management with traditional, nonspecific cytotoxic chemotherapies to treatment with molecule-specific targeted therapies that are used either alone or in combination with traditional chemotherapy and radiation therapy.

Phosphodiesterase Inhibitors in Raynaud's Phenomenon
Annals of Pharmacotherapy, 2006Objective: TO evaluate the efficacy of the phosphodiesterase type 5 (PDE5) inhibitors in the treatment of Raynaud's phenomenon. Data Sources: Searches of MEDLINE (1966–March 2006) and Web of Science (1980–March 2006) were conducted; search terms were sildenafil, tadalafil, vardenafil, phosphodiesterase, and Raynaud.

Phosphodiesterase Inhibitors (PDE Inhibitors) and Male Reproduction
2017The nonspecific PDE inhibitors, particularly the methylxanthines: caffeine, pentoxifylline (PTX), and theophylline, are known to stimulate sperm motility in vitro and have been used to treat sperm prior to insemination. The in vivo effects are less dramatic.
