Vadimezan (DMXAA) is a vascular disrupting agent, a murine STING agonist, and an inducer of cytokines such as type I IFN. Vadimezan has antitumor activity and induces a rapid cessation of blood flow in tumors without affecting blood flow in normal tissues.

MSA-2 is an orally available non-nucleotide STING agonist. The non-covalent dimer of MSA-2 binds to STING with nanomolar affinity. It shows anti-tumor activity in syngeneic mouse tumor models, synergizes with anti-PD-1, stimulates tumor secretion of interferon-β, induces tumor regression, and has long-lasting anti-tumor immunity.

Cridanimod (10-carboxymethyl-9-acridanone, CMA) is a potent STING agonist that directly binds to STING and triggers a strong antiviral response through the TBK1/IRF3 route.

Dazostinag disodium (TAK-676) is a synthetic novel interferon gene (STING) agonist that triggers STING signaling pathway activation and type I interferon activation. Dazostinag disodium (TAK-676) is also a highly effective immune system modulator with complete resolution and lasting memory of T cell immunity and the ability to promote lasting interferon-dependent anti-tumor immune responses.

SN-008 is a less active analog SN-011 which is a STING antagonist. SN-008 can be used as a negative control.

diABZI STING agonist-1 (trihydrochloride) is a stimulator of interferon genes (STING) receptor agonist.

C-178 is a covalent inhibitor of STING, binds to Cys91 on STING to block its palmitoylation and prevents recruitment and phosphorylation of TBK1 in HEK293T cells.

STING activator Compound 53 based on an oxindole core structure demonstrated robust on-target functional activation of STING (human EC50 185 nM) in immortalised and primary cells and a cytokine induction fingerprint consistent with STING activation.
