C-176 strongly reduces STING-mediated, but not RIG-I- or TBK1-mediated, IFNβ reporter activity. Pretreatment with C-176 markedly reduce the CMA-mediated induction of serum levels of type I IFNs and IL-6[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
C-176 results in a significant reduction in serum levels of type I IFNs and in a strong suppression of inflammatory parameters in the heart, with no evident signs of overt toxicity Trex1 / mice[1].
C-176 demonstrates marked amelioration of various signs of systemic inflammation in Trex1 / mice[1].

The BMDMs from the young and aged mice are pretreated with C-176 (20 µM) or STING siRNA followed by stimulation with mtDNA (100 ng/ml). The C-176 treatment effectively inhibits STING activation in both young and aged BMDMs post-mtDNA stimulation, as shown by the decreased protein levels of P-STING and P-TBK1.

The BMDMs from the young and aged mice are pretreated with C-176 (20 µM) or STING siRNA followed by stimulation with mtDNA (100 ng/ml). STING inhibition by C-176 blocks the over-activation of NLRP3 signaling in the BMDMs from the young and aged mice post-mtDNA stimulation, as shown by decreased levels of NLRP3 and Cleaved caspase-1 expression.
