STING Degrader-2
STING Degrader-2 is an orally active STING degrader that promotes proteasome-independent degradation of STING. STING Degrader-2 inhibits cGAMP-induced STING activation, suppresses STING oligomerization, and inhibits phosphorylation of STING and interferon regulatory factor 3 (IRF3). STING Degrader-2 reduces serum IFN-β and CXCL-10 levels in a cGAMP-induced autoimmune disease mouse model. STING Degrader-2 can be used for the research of autoimmune diseases.

Biological Activity
STING Degrader-2 (compound SI-43) (6 h) inhibits cGAMP-induced STING activation in THP1-Blue ISG cells with an IC50 of 0.11 μM[1].
STING Degrader-2 (1 μM; 22 h after 2 h inhibitor pretreatment) induces degradation of STINGM155 in THP1 (STINGM155) cells via a proteasome-independent, lysosome-dependent pathway[1].
STING Degrader-2 (0.05-2.5 μM; 6 h) significantly reduces IFN-β and CXCL-10 secretion in THP1 cells and bone marrow-derived macrophages[1].
STING Degrader-2 (0.1-1 μM; 6-9 h) inhibits cGAMP-induced
phosphorylation of IRF3 and STING, as well as STING dimerization and oligomerization in THP1-Blue ISG cells[1].
STING Degrader-2 (0.01-10 μM; 6-48 h) induces degradation of mutants STINGS154 and STINGM155, while sparing STINGR232 and mSTING in THP1 cells[1].
