In plants, 3′,5′-cyclic adenosine monophosphate (cAMP) is an important second messenger with varied functions; however, only a few adenylyl cyclases (ACs) that synthesize cAMP have been identified. Moreover, the biol. roles of ACs/cAMP in response to stress remain largely unclear. In this study, we used quant. proteomics techniques to identify a maize heat-induced putative disease-resistance RPP13-like protein 3 (ZmRPP13-LK3), which has three conserved catalytic AC centers. The AC activity of ZmRPP13-LK3 was confirmed by in vitro enzyme activity anal., in vivo RNAi experiments, and functional complementation in the E. coli cyaA mutant. ZmRPP13-LK3 is located in the mitochondria. The results of in vitro and in vivo experiments indicated that ZmRPP13-LK3 interacts with ZmABC2, a possible cAMP exporter. Under heat stress, the concentrations of ZmRPP13-LK3 and cAMP in the ABA-deficient mutant vp5 were significantly less than those in the wild-type, and treatment with ABA and an ABA inhibitor affected ZmRPP13-LK3 expression in the wild-type. Application of 8-Br-cAMP, a cAMP analog, increased heat-induced expression of heat-shock proteins in wild-type plants and alleviated heat-activated oxidative stress. Taken together, our results indicate that ZmRPP13-LK3, a new AC, can catalyze ATP for the production of cAMP and may be involved in ABA-regulated heat resistance.

Ammonium ions enhance proteolytic activation of adenylate cyclase and decrease its sensitivity to inhibition by “P”-site agonists was written by Yeung, Siu Mei Helena;Shoshani, Ilana;Stuebner, Dorothee;Johnson, Roger A.. And the article was included in Archives of Biochemistry and Biophysics in 1989.COA of Formula: C10H13N5O2 This article mentions the following:

A detergent-dispersed adenylate cyclase from rat brain was used to study the effects of ammonium salts and polyamines on the proteolytic activation of the enzyme by a sperm protease and on the sensitivity of adenylate cyclase to inhibition via its P-site. A purified preparation of a trypsinlike serine protease from bovine sperm was used to activate solubilized adenylate cyclase in the presence of guanosine 5′-O-(3-thiotriphosphate (GTPγS). The proteolytically activated form of adenylate cyclase was particularly sensitive to further activation by NH₄HCO₃. The activation by NH₄HCO₃ was due to the NH₄⁺ cation and was characterized by an increased V_max and by a decreased sensitivity of adenylate cyclase to inactivation by elevated concentrations of the sperm protease or by trypsin. NH₄Cl and (NH₄)₂SO₄ also caused biphasic effects on adenylate cyclase, that mimicked but were less effective than those caused by NH₄HCO₃. Consistent with observations of others, adenylate cyclase activity was enhanced by NH⁺ whether in the presence of reversible (Mn²⁺) or irreversible (GTPγS) activators. Mn²⁺– and GTPγS-stimulated activities were similarly optimally enhanced by 30 mM (NH₄)₂SO₄ and by 30-150 mM NH₄Cl or NH₄HCO₃. NH₄⁺ did not increase the activity of the purified catalytic unit. Moreover, the effect of NH₄⁺ was not accompanied by an increased rate of activation by GTPγS, suggesting that the activation of G_s (guanine nucleotide-dependent stimulatory component) may not be the primary cause of stimulation by ammonium salts. Several polyamines at millimolar concentrations blocked the stimulatory effect of NH₄⁺. This was observed when adenylate cyclase was activated by Mn²⁺, but not when it was activated by GTPγS or by the sperm protease plus GTPγS. The inhibitory effect of polyamines was not due to the formation of a complex with ATP. Both the increase in V_max of the Mn²⁺-stimulated enzyme by NH₄⁺ and the decrease in V_max caused by spermine were accompanied by an increase in the apparent K_m for MnATP. Spermine increased the IC₅₀ for inhibition of Mn²⁺-activated adenylate cyclase by 2′,5′-dideoxyadenosine (2′,5′-ddAdo) from 0.75 to 4.6 μM, consistent with the idea that increased sensitivity of P-site-mediated inhibition is associated with increased enzyme activity. In contrast, activation of Mn²⁺-stimulated adenylate cyclase by 30 mM (NH₄)₂SO₄ also reduced sensitivity to inhibition by 2′,5′-ddAdo (IC₅₀ 1.1 μM). This decreased sensitivity to inhibition by 2′,5′-ddAdo induced by NH₄⁺ was also observed on GTPS-activated or proteolytically activated adenylate cyclase. Thus, activation of adenylate cyclase by ammonium salts may be due to an effect on the conformation and(or) stability of the active form of the enzyme, leading to increased enzyme activity as well as to decreased proteolytic inactivation. In the experiment, the researchers used many compounds, for example, (2R,3S,5R)-5-(6-Amino-9H-purin-9-yl)-2-methyltetrahydrofuran-3-ol (cas: 6698-26-6COA of Formula: C10H13N5O2).

Role of regulator of G-protein signaling 2 (RGS2) in periodontal ligament cells under mechanical stress was written by Santos de Araujo, Rui M.;Oba, Yasuo;Moriyama, Keiji. And the article was included in Cell Biochemistry and Function in 2007.Related Products of 6698-26-6 This article mentions the following:

Mech. stress is thought to regulate the expression of genes in the periodontal ligament (PDL) cells. Using a microarray approach, we recently identified a regulator of G-protein signaling 2 (RGS2) as an up-regulated gene in the PDL cells under compressive force. The RGS protein family is known to turn off G-protein signaling. G-protein signaling involves the production of cAMP, which is thought to be one of the biol. mediators in response to mech. stress. Here, we investigated the role of RGS2 in the PDL cells under mech. stress. PDL cells derived from the ligament tissues of human premolar teeth were cultured in collagen gels and subjected to static compressive force. Compressive force application time-dependently enhanced RGS2 expression and intracellular cAMP levels. To examine the interrelationship between RGS2 and cAMP, the PDL cells were treated with 2′,5′-dideoxyadenosine (DDA), an inhibitor of adenyl cyclase, or antisense S-oligonucleotide (S-ODN) to RGS2 under compressive force. DDA dose-dependently inhibited RGS2 stimulated by compressive force. Blockage of RGS2 by antisense S-ODN elevated the cAMP levels compared with controls. These results indicate that cAMP stimulates RGS2 expression, which in turn leads to a decrease in the cAMP production by inactivating the G-protein signaling in the mech. stressed PDL cells. In the experiment, the researchers used many compounds, for example, (2R,3S,5R)-5-(6-Amino-9H-purin-9-yl)-2-methyltetrahydrofuran-3-ol (cas: 6698-26-6Related Products of 6698-26-6).

Antibodies raised against the adenosine receptor agonist, 5′-N-ethylcarboxamidoadenosine (NECA) was written by Nakata, Hiroyasu. And the article was included in Journal of Biochemistry in 1993.Formula: C10H13N5O2 This article mentions the following:

Antisera against the nonselective adenosine receptor agonist 5′-N-ethylcarboxamidoadenosine (NECA) were raised by immunizing rabbits with NECA-coupled bovine serum albumin. The antisera which bind [³H]NECA with high affinity were purified by affinity chromatog. using NECA-coupled Sepharose as the affinity gel without significant changes in [³H]NECA-binding properties. The order of the affinity for various adenosine receptor ligands of the purified or unpurified antisera was 5′-N-cyclopropylcarboxamidoadenosine ≥ NECA>2′,5′-dideoxyadenosine>2-chloroadenosine > theophylline > IBMX > (R)-N⁶-phenylisopropyladenosine = N⁶-cyclohexyladenosine. The specificity was similar to that of the nonreceptor NECA-binding sites, which had been found in various tissues such as human placetas and mouse P815 mastocytoma cells, rather than to that of adenosine receptors. In the experiment, the researchers used many compounds, for example, (2R,3S,5R)-5-(6-Amino-9H-purin-9-yl)-2-methyltetrahydrofuran-3-ol (cas: 6698-26-6Formula: C10H13N5O2).

Primary cilia elongation in response to interleukin-1 mediates the inflammatory response was written by Wann, A. K. T.;Knight, M. M.. And the article was included in Cellular and Molecular Life Sciences in 2012.Formula: C10H13N5O2 This article mentions the following:

Primary cilia are singular, cytoskeletal organelles present in the majority of mammalian cell types where they function as coordinating centers for mechanotransduction, Wnt and hedgehog signalling. The length of the primary cilium is proposed to modulate cilia function, governed in part by the activity of intraflagellar transport (IFT). In articular cartilage, primary cilia length is increased and hedgehog signaling activated in osteoarthritis (OA). Here, we examine primary cilia length with exposure to the quintessential inflammatory cytokine interleukin-1 (IL-1), which is up-regulated in OA. We then test the hypothesis that the cilium is involved in mediating the downstream inflammatory response. Primary chondrocytes treated with IL-1 exhibited a 50 % increase in cilia length after 3 h exposure. IL-1-induced cilia elongation was also observed in human fibroblasts. In chondrocytes, this elongation occurred via a protein kinase A (PKA)-dependent mechanism. G-protein coupled adenylate cyclase also regulated the length of chondrocyte primary cilia but not downstream of IL-1. Chondrocytes treated with IL-1 exhibit a characteristic increase in the release of the inflammatory chemokines, nitric oxide and prostaglandin E2. However, in cells with a mutation in IFT88 whereby the cilia structure is lost, this response to IL-1 was significantly attenuated and, in the case of nitric oxide, completely abolished. Inhibition of IL-1-induced cilia elongation by PKA inhibition also attenuated the chemokine response. These results suggest that cilia assembly regulates the response to inflammatory cytokines. Therefore, the cilia proteome may provide a novel therapeutic target for the treatment of inflammatory pathologies, including OA. In the experiment, the researchers used many compounds, for example, (2R,3S,5R)-5-(6-Amino-9H-purin-9-yl)-2-methyltetrahydrofuran-3-ol (cas: 6698-26-6Formula: C10H13N5O2).

Crosslinking HLA-DR mols. by monoclonal antibodies (moAbs) induces protein tyrosine phosphorylation and results in a secondary elevation of free cytoplasmic calcium concentrations in activated human T cells. Binding of bacterial superantigens or moAbs to DR mols. on activated T cells was recently reported to induce homotypic aggregation through activation of protein kinase C (PKC) and mediated by CD11a/CD54 (LFA-1/CAM-1) adhesion mols. Here, the authors report that moAbs directed against framework DR, but neither DR1, 2- and DRw52- nor DQ- and DP-specific moABs induced homotypic aggregation of antigen- and alloantigen-activated T cells, antigen-specific CD4⁺ T-cell lines, a CD8⁺ T-cytotoxic cell line, and T-leukemia cells (HUT78). Protein tyrosine kinase (PTK) inhibitor herbimycin A partly blocked class-II-induced aggregation responses. In contrast, phorbol ester (PMA)-induced aggregation was essentially unaffected. A potent inhibitor of PKC, staurosporine, inhibited both moAb- and PMA-induced aggregation responses. The aggregation responses were completely inhibited by low temperatures, cytochalasins B and E, and partly inhibited by EDTA and CD18 moAbs, but unaffected by aphidicolin, mitomycin C, an adenylate cyclase inhibitor (2’5′-dideoxyadenosine), and moAbs against other adhesion mols. (CD2/CD58, CD28/B7, CD4, and CD44). In conclusion, HLA class-II-induced aggregation responses in activated T cells appear to involve PTK and PKC activation and to be mediated through CD11a-dependent and independent adhesion pathways.

One-pot synthesis of deoxyadenosine 3′-thiophosphates was written by Szczepanik, Maciej B.;Desaubry, Laurent;Johnson, Roger A.. And the article was included in Tetrahedron Letters in 1998.Electric Literature of C10H13N5O2 This article mentions the following:

A mild and efficient one-step method of thiophosphorylation was devised for acid-sensitive nucleosides. The procedure is based on thiophosphorylation of nucleoside magnesium alkoxide by 2-chloro-2-thio-1,3,2-dioxaphospholane. The utility and efficiency of this method combined with deprotection of the resulting cyclic triester was demonstrated by its application to the synthesis of both adenosine 3′- and 5′-thiophosphates. The procedure does not require protection of the exocyclic amino group and can be successfully used for the thiophosphorylation of nucleosides that are unusually sensitive to depurination.

Evidence for a long-term influence on morphine tolerance after previous morphine exposure: role of neuronal glucocorticoid receptors was written by Lim, Grewo;Wang, Shuxing;Zeng, Qing;Sung, Backil;Mao, Jianren. And the article was included in Pain in 2005.Application of 6698-26-6 This article mentions the following:

Opioid analgesic tolerance is a pharmacol. phenomenon that overtime diminishes the opioid analgesic effect. However, it remains unknown as to whether a previous opioid exposure would have a long-term influence on opioid tolerance upon subsequent opioid administration. Here, we show that the onset and degree of antinociceptive tolerance to a subsequent cycle of morphine exposure were substantially exacerbated in rats made tolerant to and then recovered from previous morphine administration, indicating a long-term influence from a previous morphine exposure on the development of morphine tolerance. Mechanistically, morphine exposure induced a cAMP and protein kinase A-dependent upregulation of neuronal glucocorticoid receptors (GR) within the spinal cord dorsal horn, which was maintained after discontinuation of morphine administration and significantly enhanced upon a second cycle of morphine exposure. Prevention of the GR upregulation with GR antisense oligonucleotides as well as inhibition of GR activation with the GR antagonist RU38486 effectively prevented the exacerbated morphine tolerance after subsequent cycles of morphine exposure. The results indicate that a previous morphine exposure could induce lasting cellular changes mediated through neuronal GR and influence morphine analgesia upon a subsequent exposure. These findings may have significant implications in clin. opioid therapy and substance abuse. In the experiment, the researchers used many compounds, for example, (2R,3S,5R)-5-(6-Amino-9H-purin-9-yl)-2-methyltetrahydrofuran-3-ol (cas: 6698-26-6Application of 6698-26-6).

Insulin sensitizes beta-agonist and forskolin-stimulated lipolysis to inhibition by 2′,5′-dideoxyadenosine. was written by Gokmen-Polar, Y;Coronel, E C;Bahouth, S W;Fain, J N. And the article was included in The American journal of physiology in 1996.Electric Literature of C10H13N5O2 This article mentions the following:

In isolated rat adipocytes incubated in the absence of insulin, 2′,5′-dideoxyadenosine blocked the increase in total adenosine 3′,5′-cyclic monophosphate (cAMP) accumulation due to beta 1- or beta 3-catecholamine agonists and forskolin without affecting their stimulation of lipolysis. The inhibition of cAMP accumulation by 2′,5′-dideoxyadenosine was not reflected in the total cytosolic cAMP-dependent protein kinase A activity, suggesting that the inhibition of cAMP occurred in cellular compartments distinct from those involved in the regulation of bulk protein kinase A activity. However, there was a good correlation between effects of lipolytic agents on cytosolic protein kinase A activity in fat cell extracts and lipolysis. Furthermore, it was possible to see an inhibition of the increase due to beta-agonists in cAMP accumulation, protein kinase A activity, and lipolysis by 2′,5′-dideoxyadenosine in the presence of insulin. These data suggest that the readily measurable accumulation of cAMP seen with catecholamines in the absence of insulin is in a compartment separate from that involved in protein kinase A activation. In the experiment, the researchers used many compounds, for example, (2R,3S,5R)-5-(6-Amino-9H-purin-9-yl)-2-methyltetrahydrofuran-3-ol (cas: 6698-26-6Electric Literature of C10H13N5O2).

Soluble adenylyl cyclase is an acid-base sensor in epithelial base-secreting cells. was written by Roa, Jinae N;Tresguerres, Martin. And the article was included in American journal of physiology. Cell physiology in 2016.COA of Formula: C10H13N5O2 This article mentions the following:

Blood acid-base regulation by specialized epithelia, such as gills and kidney, requires the ability to sense blood acid-base status. Here, we developed primary cultures of ray (Urolophus halleri) gill cells to study mechanisms for acid-base sensing without the interference of whole animal hormonal regulation. Ray gills have abundant base-secreting cells, identified by their noticeable expression of vacuolar-type H(+)-ATPase (VHA), and also express the evolutionarily conserved acid-base sensor soluble adenylyl cyclase (sAC). Exposure of cultured cells to extracellular alkalosis (pH 8.0, 40 mM HCO3 (-)) triggered VHA translocation to the cell membrane, similar to previous reports in live animals experiencing blood alkalosis. VHA translocation was dependent on sAC, as it was blocked by the sAC-specific inhibitor KH7. Ray gill base-secreting cells also express transmembrane adenylyl cyclases (tmACs); however, tmAC inhibition by 2′,5′-dideoxyadenosine did not prevent alkalosis-dependent VHA translocation, and tmAC activation by forskolin reduced the abundance of VHA at the cell membrane. This study demonstrates that sAC is a necessary and sufficient sensor of extracellular alkalosis in ray gill base-secreting cells. In addition, this study indicates that different sources of cAMP differentially modulate cell biology.
