It also inhibits PDE III and PDE IV while significantly activating Epac, demonstrating diverse pharmacological activities [1] [2].

Msh (5-10), cyclic, as a synthetic peptide, can conjugate with fatty acids for enhanced potency.

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-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.

Cyclic di-IMP (sodium salt) (c-di-IMP) is a synthetic second messenger structurally related to the bacterial second messengers cyclic di-GMP and cyclic di-AMP . C-di-IMP has adjuvant properties when co-administered with antigens in vitro and by mucosal routes in vivo. C-di-IMP enriches the population of MHC class I and II, CD80, CD86, CD40, and CD54 positive dendritic cells derived from murine bone marrow. It also stimulates macrophages at 500 ng/ml. Mice immunized with β-galactosidase (β-gal) plus c-di-IMP through the intranasal route show a humoral immune response, evidenced by an increase in IgG titers up to 2-fold compared to mice immunized with β-gal alone. Mice immunized with β-gal plus c-di-IMP also exhibit a Th1/Th2 response, indicating that the adjuvant activity of c-di-IMP leads to a cellular immune response as well.

Cyclic di-UMP is a pyrimidine-containing cyclic dinucleotide (CDN).1It is produced by bacterial cGAS/DncV-like nucleotidyltransferases (CD-NTases), such as LpCdnE02 fromL. pneumophila, and binds to cGAS, in the apo or dsDNA-bound forms, with reduced affinity compared to 2'3'-cGAMP or 3'3'-cGAMP .1,2Cyclic di-UMP is intended for use as a negative control for cyclic di-GMP signaling. 1.Whiteley, A.T., Eaglesham, J.B., de Oliveira Mann, C.C., et al.Bacterial cGAS-like enzymes synthesize diverse nucleotide signalsNature564(7747)194-199(2019) 2.Hall, J., Ralph, E.C., Shanker, S., et al.The catalytic mechanism of cyclic GMP-AMP synthase (cGAS) and implications for innate immunity and inhibitionProtein Sci.26(12)2367-2380(2017)

Cyclic ADP-ribose (cADP-ribose) is an endogenous metabolite of NAD+ that mobilizes the release of stored Ca2+ in the endoplasmic reticulum via ryanodine receptors in various cell types.[1],[2],[3],[4],[5] This second messenger is generated via the cADP-ribose synthases CD38 and CD157.[6],[5],[7] cADP-Ribose may also trigger the cell surface Ca2+ influx channel TRPM2 in a temperature-dependent manner.[8] In vitro, cADP-ribose modulates Ca2+ signaling in rat and mouse cardiomyocytes treated with isoproterenol , and treatment with this metabolite at 100 μM under heat stress conditions induces the release of oxytocin from the mouse hypothalamus.[9],[4]

Cyclic ADP-ribose ammonium (cADPR ammonium) is a potent calcium mobilization second messenger synthesized from NAD+ by ADP-ribosyl cyclase.

Cyclic ADP-ribose (cADP-ribose) is a calcium mobilizing nucleotide that is biosynthesized from NAD+ by cADP-ribose synthases, including CD38. cADP-Ribose appears to activate calcium channels in intracellular membranes, which in turn activate ryanodine receptors. 8-bromo-cADP-Ribose is a stable, cell-permeable analog that blocks calcium release evoked by cADP-ribose in sea urchin egg homogenates with an IC50 value of 1.7 μM. It is commonly used to investigate intracellular signaling through cADP-ribose in isolated cells and tissues.
