STING agonist-30 is a potent activator of STING-dependent immune responses, demonstrating broad-spectrum antiviral effects against viruses such as HSV (Herpes Simplex Virus), rotavirus, and SARS-CoV-2 (Severe Acute Respiratory Syndrome Coronavirus 2).

ADU-S100 (MIW815) is a synthetic cyclic dinucleotide agonist of STING, elicits potent and durable anti-tumor immunity when administered IT in pre-clinical syngeneic tumor models.

MSA-2, a potent and orally available non-nucleotide STING agonist, has EC50s of 8.3 and 24 μM for human STING isoforms WT and HAQ, respectively. MSA-2 shows antitumor activity and stimulates interferon-β secretion in tumors, induces tumor regression with durable antitumor immunity, and synergizes with anti-PD-1 in syngeneic mouse tumor models.
