Cyclic GMP-AMP Synthase

cGAS

Cyclic GMP-AMP synthase (cGAS) is a cytosolic DNA sensor that activates a type-I interferon response. cGAS binds to microbial DNA as well as self DNA that invades the cytoplasm, and catalyzes cGAMP synthesis. cGAMP then functions as a second messenger that binds to and activates the endoplasmic reticulum protein STING to trigger type-I IFNs production. STING recruits TBK1, which phosphorylates transcription factors, such as IRF3/7, and other substrates, such as IKKα, cRel, and p62.

cGAS is a critical regulator of inflammatory and autophagy responses in Huntington disease (HD). cGAS can induce signaling that is known to promote the up-regulation of inflammatory genes and play a critical role in age-related macular degeneration and cellular senescence. cGAS also plays a major role in the regulation of autophagy; this indicates that there is a close molecular and signaling link between inflammatory response and autophagy.

  • HY-177338
    STING agonist-45
    STING agonist-45 is a selective STING agonist (EC50 = 0.28 μM). STING agonist-45 activates the innate immune response through the cGAS-STING pathway, upregulating key markers such as p-TBK1 and IRF3. STING agonist-45 exhibits robust STING activation in human peripheral blood mononuclear cells (PBMCs), inducing the production of type I interferons (such as IFN-β) and downstream cytokines (such as TNF-α and IL-6). STING agonist-45 enhances anti-tumor immunity, inhibits tumor growth, and increases CD8+ T cell infiltration in mouse models. STING agonist-45 is promising for the study of STING-related diseases.

    HA-1004 hydrochloride
    Inhibitor
    HA-1004 hydrochloride is a selective inhibitor of PKA, which can inhibit lipolysis and induce vascular relaxation. HA-1004 hydrochloride is also a dual inhibitor of cyclic GMP-dependent protein kinase and cyclic AMP-dependent protein (Cyclic GMP-AMP Synthase), and is involved in smooth muscle, second messenger, cyclic AMP and cyclic GMP regulation mechanisms. HA-1004 hydrochloride an antagonist for calcium, that can be used as a vasodilator to inhibit the contraction of rabbit aortic strips, or to antagonize ERK and tyrosine hydroxylase (TH) phosphorylation in morphine abstinence rat models.

    QKY-613
    Activator
    QKY-613 is a prodrug that enhances immune surveillance by targeting nucleic acid modification pathways. QKY-613 promotes the selective incorporation of 6mdA (N6-methyldeoxyadenosine) into viral DNA, enhancing the phase separation potential of DNA, thereby increasing the activation of cGAS and strengthening host immune surveillance. In virus-infected mouse models, QKY-613 significantly reduced mortality in aged mice. QKY-613 holds promise for research on nucleic acid modification-based immune surveillance mechanisms.

    Cladophorol A
    Inhibitor
    Cladophorol A is a cGAS inhibitor that binds to the conserved adenosine nucleobase binding site of cGAS, thereby blocking its activity. At non-cytotoxic concentrations, Cladophorol A effectively inhibits the overactivation of the cGAS-STING pathway with an IC50 of 370 nM. Cladophorol A holds potential for research on inflammatory diseases related to the overactivation of the cGAS-STING pathway.
