cyclic amp

Cyclic AMP (cAMP) (Adenosine 3',5'-cyclophosphate) combined with vitamin C treatment of children with viral myocarditis has exact curative effect, and it can improve cardiac function of patients and improve immune function.

Cyclic AMP-13C5 is the deuterium-labeled form of Cyclic AMP.

Cyclic di-AMP (c-di-AMP) is a second messenger produced by bacteria but not by mammals. Generated by a family of diadenylate cyclases, c-di-AMP can impact bacterial cell growth, cell wall homeostasis, pathogenicity, and other cellular functions. Bacteria-derived cyclic dinucleotides, including c-di-AMP, trigger the expression of interferon genes in mammalian cells.

Rp-8-CPT-cAMP is a structural combination of the lipophilic and non-hydrolyzable cAMP analogs, 8-CPT-cyclic AMP and Rp-cyclic AMPS .[1] It functions as a site-selective inhibitor of protein kinase A (PKA) type I and II, with preference towards site A of type I and site B of type II.2 By occupying cAMP binding sites at the regulatory subunit of PKA, Rp-8-CPT-cAMP prevents the kinase holoenzyme from dissociative activation.[2],[3]

Cyclic tri-AMP is a key element of the cyclic oligonucleotide-based anti-phage signaling system (CBASS), functioning as a second messenger in the immune defense against viral infections. It activates DNA endonuclease NucC through binding, leading to cell death and demonstrating antiviral properties.

Sp-cAMPS sodium salt is an analog of cAMP that serves as a potent activator of cAMP-dependent PKA I and PKA II, and as a competitive phosphodiesterase (PDE3A) inhibitor with a Ki of 47.6 μM. It also binds the PDE10 GAF domain with an EC50 of 40 μM [1] [2] [3].

8-CPT-Cyclic AMP sodium is an activator of cAMP-dependent PKA and cAMP receptor activator, and also an inhibitor of cAMP-specific phosphodiesterase (PDE VA) (IC50 = 0.9 μM). The IC50 values for PDE III and PDE IV are 24 and 25 μM, respectively.

Rp-8-bromo-Cyclic AMPS (Rp-8-bromo-cAMPS) is a cell-permeable cAMP analog that combines an exocyclic sulfur substitution in the equatorial position of the cyclophosphate ring with a bromine substitution in the adenine base of cAMP. It acts as an antagonist of cAMP-dependent protein kinases (PKAs) and is resistant to hydrolysis by cyclic nucleotide phosphodiesterases. Rp-8-bromo-cAMPS more effectively antagonizes cAMP-dependent activation of purified PKA type I from rabbit muscle than PKA type II from bovine heart.

8-Bromo-cAMP is a cell-permeable cAMP analogue and activator of CAMP-dependent protein kinase A that induces cell death and reduces proliferation.

8-PIP-cAMP is a selective activator of cAMP-dependent protein kinase, primarily utilized in cancer research.

cAMP sodium(Cyclic adenosine monophosphate sodium) is a derivative of adenosine triphosphate (ATP) and a cellular second messenger. It transmits signals within cells that are carried by primary messengers (such as adrenaline) unable to enter the cell, performing crucial regulatory functions.

2',3'-cGAMP sodium (2'-3'-cyclic GMP-AMP sodium) is a second messenger in cellular innate immunity, catalyzed by cGAMP synthase (cGAS) under DNA binding conditions. It binds to STING to form a dimer, inducing the production and expression of interferon-β and other cytokines.

Theophylline (1,3-Dimethylxanthine) is a methyl xanthine derivative from tea with diuretic, smooth muscle relaxant, bronchial dilation, cardiac, and central nervous system stimulant activities. It inhibits the 3', 5'-cyclic nucleotide phosphodiesterase that degrades cyclic AMP, thus potentiating the actions of agents that act through adenylyl cyclases and cyclic AMP.

HNMPA is a membrane impermeable inhibitor of insulin receptor tyrosine kinase. HNMPA inhibits tyrosine and serine autophosphorylation by the human insulin receptor. HNMPA exhibits no effect on cyclic AMP-dependent protein kinase or protein kinase C activities.

KL8604166 (UCB-11056) is a potential puzzle compound.UCB-11056 amplifies the formation of inducible cyclic AMP in rat brain tissue.

Ibudilast (MN-166)(KC-404;AV-411;MN-166) is a relatively nonselective phosphodiesterase inhibitor. It is approved for use as an anti-inflammatory in Japan.

Malantide acetate is a dodecapeptide phosphorylated by cyclic AMP-dependent protein kinase (PKA), and increases PKA activity.Malantide is a synthetic peptide that is phosphorylated by PKA and is used to measure PKA activity in vitro.

2',3'-cGAMP is an endogenous cyclic dinucleotide (CDN) produced by cGAS (cGAMP synthase) in response to double-stranded DNA in the cytoplasm. It acts as a STING activator and ligand, inducing interferons (IFNs) via the TBK1/IRF3 pathway and pro-inflammatory factors via the NF-κB pathway.

c-di-AMP (Cyclic diadenylate) is a STING agonist that binds to the transmembrane protein STING, thereby activating the TBK3-IRF3 signaling pathway.

G150 inhibited interferon expression triggered by DSDNA with IC50 of 10.2 nM.G150 is an effective and highly selective inhibitor of human cyclic GMP-AMP synthase (H-CGAS).

IRAK4-IN-4 (compound 15) inhibits cyclic GMP-AMP synthase (cGAS) with an IC50 of 2.1 nM.IRAK4-IN-4 is an interleukin-1 receptor–associated kinase 4 (IRAK4) inhibitor, has an IC50 of 2.8 nM.

PF-06928215 is an inhibitor of cGAS (cyclic GMP-AMP Synthase) (IC50 of 4.9 μΜ).

Win-62005 is an inhibitor of cyclic AMP phosphodiesterase III (PDE III)(Kis: 25 and 26 nM for rat heart and canine aorta).

cGAMP is an endogenous second messenger in metazoans and triggers interferon production in response to cytosolic DNA. It also is a STING ligand.
