Evidence against mediation of adenosine-3',5'-cyclic monophosphate in the bud-inducing effect of cytokinins in moss protonemata

Acta Societatis Botanicorum Poloniae, 2015
Effects Oif adenosdne-3',5'-cyclic monophosphate (cAMP), N6,O2-dibuityryl adenosine-3',5'-cyclic monophosphate (DBcAMP), caffeine and theophylline on the bud-inducing activity of cytokinin in the protonema of two moss species, Ceratodon purpureus and ...

Effects of PDE4 inhibitors on lipopolysaccharide-induced priming of superoxide anion production from human mononuclear cells

Mediators of Inflammation, 2001
Aims: Phosphodiesterase 4 (PDE4) inhibitors have been described as potent anti-inflammatory compounds, involving an increase in intracellular levels of cyclic 3',5'-adenosine monophosphate (AMP).

A short review on structure and role of cyclic-3',5'-adenosine monophosphate-specific phosphodiesterase 4 as a treatment tool

Journal of Research in Pharmacy Practice, 2015
Cyclic nucleotide phosphodiesterases (PDEs) are known as a super-family of enzymes which catalyze the metabolism of the intracellular cyclic nucleotides, cyclic-3',5'-adenosine monophosphate (cAMP), and cyclic-3',5'-guanosine monophosphate that are ...

Adenosine A2A-Receptor Stimulation Inhibits Lipopolysaccharide-Induced Interleukin-18 Production in Monocytes

Journal of Pharmacological Sciences, 2007
Adenosine inhibited interleukin (IL)-18 production in lipopolysaccharide (LPS)-stimulated monocytes. The action of adenosine was antagonized by an adenosine A2A-receptor (A2AR) antagonist and was mimicked by an A2AR agonist, suggesting that the ...

Polyamines and cellular adenosine 3′ :5′-cyclic monophosphate [PDF]

Biochemical Journal, 1979
The effect of polyamines on the cellular concentrations of cyclic AMP was studied. It was shown that 1 microM-spermine caused a decrease in cyclic AMP in chick-embryo heart cells, chick-embryo fibroblasts, neuroblastoma, glioma and neuroblastoma-glioma hybrid cells, grown in culture.

The Construction and Application of a New Screening Method for Phosphodiesterase Inhibitors

Biosensors
Phosphodiesterases (PDEs), a superfamily of enzymes that hydrolyze cyclic adenosine monophosphate (cAMP) and cyclic guanosine monophosphate (cGMP), are recognized as a therapeutic target for various diseases.

Study of Cyclic Adenosine Monophosphate Microdomains in Cells

, 2005
Cyclic adenosine monophosphate (cAMP) controls the physiological response to many diverse extracellular stimuli. To maintain signal specificity, cAMP-mediated signaling is finely tuned by means of a complex array of proteins that control the spatial and temporal dynamics of the second messenger within the cell.

“Cyclic nucleotides in plants: from obscure messengers to central regulators“

Frontiers in Plant Science
This review examines the historical trajectory of cyclic nucleotides (cNMPs) research in plants, a field that has encountered prolonged challenges and skepticism, contrasting sharply with its rapid validation in animal systems.
