Description

Biochem/physiol Actions

C-178 is a potent and selective inhibitor against murine, but not human, stimulator of interferon genes (STING) via covalent modifiation of mSTING Cys91. C-178 inhibits mSTING-mediated IFNβ reporter activity (IC50 <500 nM) without affecting RIG-I, and blocks (0.5 μM) downstream TBK1 phosphorylation induction by STING agonist CMA (1.4 h) in mSTING-expressing HEK293T cells.

Potent and selective, Cys91-targeting covalent inhibitor against murine, but not human, STING.
