UM-232
UM-232 is a highly selective covalent STING antagonist with an EC50 of 6.20 μM in STING R232-expressing THP-1 cells. UM-232 covalently targets C292 and C309 cysteines of STING, blocks STING oligomerization and inhibits downstream TBK1/IRF3 activation and proinflammatory cytokine transcription. UM-232 has low off-target reactivity and good hepatic stability, serving as a chemical probe for STING-driven autoimmune and inflammatory diseases including Aicardi-Goutières syndrome (AGS), Systemic Lupus Erythematosus (SLE) and Amyotrophic Lateral Sclerosis (ALS).

UM-232 covalently engages C292 and C309 residues of STING in HEK293T cells[1].
UM-232 (2.5-5 μM; 1 h) inhibits diABZI (diABZI STING agonist-1) (HY-112921A)-triggered transcription of Ifnb, Il6, and Cxcl10 in a dose-dependent manner in BMDMs[1].
UM-232 (5 μM; 1 h) inhibits STING activation and downstream signaling in vitro in BMDMs[1].
UM-232 (5 μM; 15 min) possesses favorable metabolic stability in human liver microsomes and superior stability relative to control compound in mouse liver microsomes[1].
