C-178 targets the poorly characterized N-terminal portion of mmSTING that includes the transmembrane domains. Moreover, C-178 interferes with this process by inhibiting the palmitoylation of STING. C-178 does not appreciably affect STING responses in human cells.
C-178 (0-1 μM; 1 hour) alone does not appreciably affect the gene expression profile of BMDMs. In addition, it inhibits the CMA-induced phosphorylation of TBK1.
C-178 (1 μM; 1 hour) decreases cdG, dsDNA, CMA and LPS-induced Ifnb1 expression in mouse bone marrow-derived macrophages.
C-178 (1 μM; 0.5-4 hours) inhibits the CMA-induced p-TBK1 and sting protein expression as a time-dependent manner in mouse embryonic fibroblasts.
