c-di-AMP diammonium  (Synonyms: Cyclic diadenylate diammonium; Cyclic-di-AMP diammonium)

c-di-AMP diammonium 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. c-di-AMP diammonium is also a bacterial second messenger, which regulates cell growth, survival, and virulence, primarily within Gram-positive bacteria, and also regulates host immune response. c-di-AMP diammonium acts as a potent mucosal adjuvant stimulating both humoral and cellular responses^[1][2][3][4].

STING^[3]

c-di-AMP diammonium signaling is a central factor in many Gram-positive bacteria regulating cell wall synthesis, potassium ion channels, DNA repair, and biofilm formation. c-di-AMP is also essential for cell growth, survival, and virulence of several well-known human pathogenic bacteria including S. aureus, L. monocytogenes, S. pyogenes, and Mycobacterium spp^[1].
c-di-AMP diammonium combines with model antigens, such as OVA or β-Gal, acts as a potent mucosal adjuvant stimulating both humoral and cellular responses^[4].
