Biological activity
Description
Target:
In Vivo
STING agonist-3 (Compound 3) (subcutaneous injection; 2.5mg/kg) activates secretion of IFN-β, IL-6, TNF-α, and KC/GROα (CXCL1) in wild-type but not Sting−/− mice, induces STING-dependent activation of type-I interferon and pro-inflammatory cytokines in vivo[1]. STING agonist-3 (Compound 3) (subcutaneous injection; 3 mg/kg) exhibits systemic exposure with a half-life of 1.4 h and achieves systemic concentrations with EC50=200 ng /ml for mouse STING[1]. STING agonist-3 (Compound 3) (injection intravenously; 1.5 mg/kg) results in significant tumor growth inhibition, and improves survival with 8 out of 10 mice remaining tumors free at day 43[1]. Animal Model: Mice with approximately 100 mm3 subcutaneous CT-26 tumors[1] Dosage: 1.5 mg/kg Administration: Injection intravenously; 1.5 mg/kg; 1 day, 4 days, 8 days Result: Resulted in significant tumor growth inhibition.
In Vitro
STING agonist-3 (Compound 3) induces dose-dependent activation of STING and secretion of IFN-β with ECapp50s of 130 nM,186 nM in human PBMCs and Mouse PBMCs[1].
