STING-IN-19
STING-IN-19 is a STING inhibitor with a Kd value of 2.31 μM for human STING. STING-IN-19 inhibits the activation of TBK1 and IRF3 by binding to STING, thereby suppressing the activation of downstream signaling pathways. STING-IN-19 reduces the levels of key inflammatory cytokines IL-1β, IL-6 and TNF-α in colonic tissues and serum of mice with ulcerative colitis. STING-IN-19 can be used in studies related to ulcerative colitis.

STING-IN-19 (compound Z55) binds directly to recombinant human STING1 with high affinity, with a Kd value of 2.31 μM; it potently inhibits HT-DNA-induced STING pathway activation in IRF-Luc-THP-1 cells, with an IC50 of 0.40 μM; it exhibits moderate cytotoxicity against IRF-Luc-THP-1 cells, with a cell viability IC50 of 4.75 μM[1].
STING-IN-19 (10 μM; 18 h) directly binds to endogenous STING in RAW264.7 cells, increasing the thermal stability of this protein by 4.31 °C[1].
STING-IN-19 potently inhibits DMXAA-induced activation of the STING pathway in RAW264.7 murine macrophages, and exhibits no cytotoxicity at concentrations up to 3 μM[1].
