STING-IN-2
Based on 12 publication(s) in Google Scholar
STING-IN-2 (C-170) is a potent and covalent STING inhibitor. STING-IN-2 efficiently inhibits both mouse STING (mmSTING) and human STING (hsSTING). STING-IN-2 can be used for autoinflammatory disease research.

Biological Activity
THP-1 cells are pretreated with STING-IN-2 (C-170; 0.5 μM) and stimulated with cGAMP. STING-IN-2 (C-170) treatment decreases the IFNB1 and TNF mRNA levels, and also reduces the p-TBK1 levels[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
