SMU-C409 is a TLR1/2 agonist with an EC50 of 65 nM in HEK-Blue hTLR2 Cells. SMU-C409 activates the TLR1/2–MyD88–NF-κB pathway, inducing TNF-α/IL-1β secretion and robust immune cell activation for antitumor immunomodulation. SMU-C409 shows low toxicity in virto. SMU-C409 can be used for cancer immunotherapy research.

Description

SMU-C409 is a TLR1/2 agonist with an EC50 of 65 nM in HEK-Blue hTLR2 Cells. SMU-C409 activates the TLR1/2–MyD88–NF-κB pathway, inducing TNF-α/IL-1β secretion and robust immune cell activation for antitumor immunomodulation. SMU-C409 shows low toxicity in virto. SMU-C409 can be used for cancer immunotherapy research[1].

In Vitro

SMU-C409 (0-100 nM) selectively activates the hTLR2 signaling pathway in HEK-Blue hTLR2 cells while showing negligible activity on other TLR subtypes (hTLR3/4/7/8)[1].
SMU-C409 (0-100 μM, 24 h) shows low toxicity in HEK-Blue hTLR2 cells, PBMC, B16−F10 cells and MCF-7 cells[1].
SMU-C409 (0-50 μM, 0-24 h) specifically targets and activates TLR2 in HEK-Blue hTLR2 and THP-1 cells[1].
SMU-C409 (0-100 μM, 0-700 min) binds hTLR2 protein with the Kd of 72.4 nM[1].
SMU-C409 (0-20 μM, 0-120 min) activates the TLR1/2 hetero dimer, triggering downstream signaling via MyD88 recruit ment, which promotes phosphorylation of MyD88-NF-κB pathway components and dissociation of inhibitory proteins in THP-1(Phorbol 12-myristate 13-acetate (HY-18739) PMA differentiated) cells[1].
SMU-C409 (0.01-10 μM, 24 h) plays a pivotal role in inflammatory signaling by stimulating downstream cytokine production through the NF-κB pathway and maintains conserved species specificity across different immune cell types and signaling axes in THP-1 cells (PMA-differentiated), PBMC cells, mouse peritoneal macrophages and mouse RAW264.7 cells[1].
SMU-C409 (0-10 μM, 48 h) exhibits a degree of immune activating activity in CD3 + cells, CD4 + cells, CD8 + cells, Monocytes, B cells and NK cells[1].
SMU-C409 (1-20 μM, 24 h) enhances immune cell mediated induction of SJSA-1 apoptosis, showing the potential for antitumor immune activity[1].
SMU-C409 (8 h) exhibits markedly improved plasma stability with degradation rate constant (k) of 0.0003 min -1 in rat plasma[1].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
