ADU-S100 (MIW815) is a synthetic cyclic dinucleotide (CDN) agonist (activator) of Stimulator of Interferon Genes (STING), a receptor crucial to activate the innate (endogenous) immune system.
ADU-S100 ammonium salt (ML RR-S2 CDA ammonium salt; MIW815 ammonium salt), an activator of stimulator of interferon genes (STING), leads to potent and systemic tumor regression and immunity.
c-di-AMP (Cyclic diadenylate) is a STING agonist, which binds to the transmembrane protein STING thereby activating the TBK3-IRF3 signaling pathway, subsequently triggering the production of type I IFN and TNF.
