SNX281
Based on 1 Customer Validation
SNX281 is a selective STING agonist, with IC50 values of 4.1, 4.5, 10.7, and 3.7 μM against human, mouse, rat, and monkey STING, respectively. SNX281 undergoes homodimerization at the STING binding site, triggering a conformational shift of STING from an inactive open state to an active closed state, thereby driving downstream STING-dependent signaling pathways. SNX281 induces type I interferons, IFN-β, TNF-α, IL-6, cytokine release, T cell responses, and long-lasting immune memory. SNX281 exhibits anti-tumor activity and is applicable to research related to colorectal cancer, melanoma, advanced solid tumors, lymphoma, and ovarian cancer.

Activité biologique
SNX281 (25 µM; 1 h) induces STING translocation, TBK1 phosphorylation, and IRF3 nuclear translocation in HEK293T cells stably expressing human HAQ-mutant STING[1].
SNX281 (10 µM; 0-2 h) rapidly induces the phosphorylation of STING, TBK1 and IRF3 in THP-1 cells[1].
SNX281 (6 h) induces dose-dependent secretion of IFN-β, TNF-α and IL-6 in THP-1 cells[1].
SNX281 induces IRF3 and NF-κB reporter gene activity in a STING-dependent manner in THP1-Dual cells, with an EC50 value of 1.1 µM for human wild-type STING and 1.7 µM for human HAQ mutant STING[1].
SNX281 (6 h) induces dose-dependent IFN-β secretion in J774A.1 mouse macrophage-like cells, with an EC50 of 5.4 µM[1].
SNX281 (6 h) induces dose-dependent IFN-β secretion in peripheral blood mononuclear cells of cynomolgus monkeys, with an EC50 of 2.4 µM[1].
SNX281 induces STING-dependent pathway activation in THP-1 cells and human peripheral blood mononuclear cells (PBMCs), and promotes the production of IFN-β, TNF-α and IL-6[2].
