SN-011_product_DataBase

Bioactivity

SN-011 is a potent and selective mouse and human STING inhibitor, with an IC50 of 76 nM for STING signaling. SN-011 competes with cyclic dinucleotide (CDN) for the binding pocket of the STING dimer, blocking CDN binding and STING activation. SN-011 can be used for the research of STING-driven autoimmune and inflammatory disease[1].

Target

IC50: 76 nM (STING signaling)

Invitro

SN-011 (1 μM; pretreated for 6 h) significantly suppresses the STING stimulator-induced expression of Ifnb, Cxcl10, and Il6 mRNA in mouse embryonic fibroblasts (MEFs)[1].SN-011 (0.001-10 μM; pretreated for 6 h) inhibits 2′3′-cGAMP-induced Ifnb expression in MEFs, mouse bone marrow-derived macrophages (BMDMs) and human foreskin fibroblasts (HFFs) with IC50s of 127.5, 107.1, and 502.8 nM, respectively[1].SN-011 (1 μM; pretreated for 3 h) inhibits 2′3′-cGAMP-induced STING oligomerization and phosphorylation in HFFs[1].SN-011 (1 μM) suppresses HSV-1 infection (4 h), HT-DNA (1 h), or 2′3′-cGAMP stimulation (30 min) induced STING ER-to-Golgi translocation[1].
