A dose-ranging study of the inhaled dual phosphodiesterase 3 and 4 inhibitor ensifentrine in COPD [PDF]
Background Many patients with chronic obstructive pulmonary disease (COPD) still experience daily symptoms, exacerbations, and accelerated lung function decline, even when receiving maximal combined treatment with inhaled long-acting bronchodilators and ...

Diastereomeric Specificity of 2',3'-Cyclic Nucleotide 3-Phosphodiesterase [PDF]
The diastereomers of adenosine and uridine 2',3'-cyclic phosphorothioates were tested as substrates for 2',3'-cyclic nucleotide 3'-phosphodiesterase from bovine brain. The enzyme cleaves the Sp (or exo) diastereomers efficiently, whereas the Rp (or endo) diastereomers are resistant to hydrolysis, even after long incubation.

3′:5′‐Cyclic Nucleotide Phosphodiesterases in Rat Tissues [PDF]
The rates of enzymatic hydrolysis of cyclic AMP, cyclic GMP, cyclic IMP, cyclic UMP, cyclic CMP and cyclic dTMP (all 3′:5′‐phosphates) have been assayed in several rat tissues. Subcellular distribution studies indicated that, in all tissues except brain and heart, most of the enzymatic activity is confined to the soluble cell fraction.The purine cyclic

PDE Inhibitors and Autophagy Regulators Modulate CRE-Dependent Luciferase Activity in Neuronal Cells from the Mouse Suprachiasmatic Nucleus [PDF]
Background: Signaling pathways like those depending on cAMP/PKA, calcium/calmodulin/CaMK, MEK-1/MAPK or PI3K/Akt have been described to modulate suprachiasmatic nucleus (SCN) neuronal signaling via influencing transcription factors like CREB.

Identification of a Glycerophosphocholine Phosphodiesterase, GDE5, in chicken [PDF]
Glycerophosphodiester phosphodiesterase (GDPD/GDE) catalyzes the hydrolysis of glycerophosphodiesters to glycerol 3-phosphate and alcohol. It was discovered that the glycerophosphodiesterase family plays a role in lipid metabolism and signal pathway in ...

Introduction: Rewarming from accidental hypothermia is often complicated by hypothermia-induced cardiovascular dysfunction, which could lead to shock. Current guidelines do not recommend any pharmacological treatment at core temperatures below 30°C, due ...

Cyclic Nucleotide Phosphodiesterase 3 Signaling Complexes [PDF]
The superfamily of cyclic nucleotide phosphodiesterases is comprised of 11 gene families. By hydrolyzing cAMP and cGMP, PDEs are major determinants in the regulation of intracellular concentrations of cyclic nucleotides and cyclic nucleotide-dependent signaling pathways. Two PDE3 subfamilies, PDE3A and PDE3B, have been described.

Phosphodiesterase 3 inhibition and cough in elderly asthmatics [PDF]
AbstractAimsCough is a common symptom of bronchial asthma, a chronic inflammatory airway disease. Recently, the therapeutic effects of selective phosphodiesterase (PDE) inhibitors have been focused on bronchial asthma. This study was designed to investigate the clinical effect of PDE 3 inhibition on cough reflex sensitivity in elderly patients with ...

Bacterial cyclic AMP-phosphodiesterase activity coordinates biofilm formation. [PDF]
Biofilm-related infections are a major contributor to human disease, and the capacity for surface attachment and biofilm formation are key attributes for the pathogenesis of microbes. Serratia marcescens type I fimbriae-dependent biofilms are coordinated
