STING agonists and inhibitors act on an adaptor protein of the cytosolic DNA sensing pathway. Stimulator of interferon genes (STING) was described in 2008 as an endoplasmic reticulum adaptor needed for innate immune signaling and type I interferon induction. STING binds cyclic dinucleotides directly, both bacterial molecules such as cyclic di-GMP and the mammalian second messenger made by cyclic GMP-AMP synthase (cGAS) once it detects cytosolic DNA. Agonists listed here include 2',3'-cGAMP, Cyclic-di-GMP, ADU-S100 disodium salt (MIW815 disodium salt) and numbered compounds such as STING agonist-1. Inhibitors include H-151 and the mouse-directed C-176 and C-178, which belong to a class of covalent compounds that modify a cysteine of the transmembrane region.

STING antagonist-1 is a selective antagonist of the Stimulator of Interferon Genes (STING) pathway, exhibiting an IC50 of 3.8 nM. This compound is valuable for research applications related to autoimmune and inflammatory diseases, allowing for the investigation of STING-mediated cellular responses and therapeutic interventions.
SB24011 is a selective STING modulator that inhibits the TRIM29-STING protein-protein interaction. By binding to STING, it effectively prevents TRIM29-induced K48-linked ubiquitination, leading to an increase in intracellular STING protein levels. This compound promotes the expression of inflammatory cytokines and enhances STING-mediated immune responses, demonstrating abscopal antitumor activity that stimulates tumor regression and T cell infiltration. SB24011 is particularly relevant for research on colon cancer and melanoma, showing potential synergy when used in conjunction with STING agonists or anti-PD1 antibodies.
STING modulator-4 (compound AIH05) is a competitive modulator of the Stimulator of Interferon Genes (STING), exhibiting a Ki of 0.0933 μM for the R232H variant of STING. This compound demonstrates biological activity with an EC50 value exceeding 10 μM for phosphorylated IRF3 in THP-1 cells. STING modulator-4 is significant for research in immunology and enhances understanding of STING-mediated signaling pathways.
STING antagonist-3 is a highly effective antagonist of the stimulator of interferon genes (STING) with an IC50 of 2.3 nM against human wild-type STING, as well as against the gain-of-function mutants N154S and V155M. This compound has been shown to inhibit the production of IFN-α2a in stimulated human whole blood and to reduce IP-10 levels in activated human dermal microvascular endothelial cells (HMVEC-d). STING antagonist-3 is valuable for research in autoimmune diseases, autoinflammatory diseases, interferonopathies, and fibrotic disorders.

Clonixeril (NSC 335504) is a non-nucleotide modulator of human STING (hSTING), exhibiting a unique dual mechanism of action. It acts as a weak agonist at micromolar concentrations while demonstrating antagonistic properties of the hSTINGWT pathway at low femtomolar and attomolar levels. Clonixeril effectively reduces hSTING oligomerization, proving useful in elucidating the complexities of STING signaling and its role in immune responses. This compound serves as a valuable tool for research in immunology and drug discovery targeting STING-related pathways.
