CU-T12-9 是一种有效的 TLR1/2 激动剂（HEK-Blue hTLR2 SEAP 测定中 EC50 为 52.9 nM）。它通过激活 NFkB 通路、上调促炎细胞因子以及增强 TLR1 和 TLR2 二聚化发挥作用。CU-T12-9 可激活先天性和适应性免疫系统。

CU-T12-9 is a potent TLR1/2 agonist(EC50 of 52.9 nM in HEK-Blue hTLR2 SEAP assay).?It acts by activating the NFkB pathway, upregulating proinflammatory cytokines, and enhancing TLR1 and TLR2 dimerization.CU-T12-9 activates both the innate and the adaptive immune systems. CU-T12-9 selectively activates the TLR1/2 heterodimer, not TLR2/6. CU-T12-9 signals through NF-κB and invokes an elevation of the downstream effectors TNF-α, IL-10, and iNOS.CU-T12-9 directly targets TLR1/2 to initiate downstream signaling.?CU-T12-9 specifically induces TLR1/2 activation, which can be blocked by either the anti-hTLR1 or the anti-hTLR2 antibody, but not the anti-hTLR6 antibody.?By binding to both TLR1 and TLR2, CU-T12-9 facilitates the TLR1/2 heterodimeric complex formation, which in turn activates the downstream signaling.?Fluorescence anisotropy assays revealed competitive binding to the TLR1/2 complex between CU-T12-9 and Pam3CSK4 with a half-maximal inhibitory concentration (IC50) of 54.4 nM.?CU-T12-9 signals through nuclear factor κB (NF-κB) and invokes an elevation of the downstream effectors tumor necrosis factor-α (TNF-α), interleukin-10 (IL-10), and inducible nitric oxide synthase (iNOS).?

CU-T12-9 directly targets TLR1/2 to initiate downstream signaling. By binding to both TLR1 and TLR2, CU-T12-9 facilitates the TLR1/2 heterodimeric complex formation, which in turn activates the downstream signaling. CU-T12-9 activates the TLR1/2 pathway by inducing NF-κB activation to trigger downstream signaling, such as secreted embryonic alkaline phosphatase (SEAP), NO, and TNF-α.CU-T12-9 (0.39-100 μM; 24 hours) does not produce toxicity up to 100 μM in HEK-Blue hTLR2 and Raw 264.7 cells. CU-T12-9 up-regulates the mRNA levels of TLR1, TLR2, TNF, IL-10, and iNOS. CU-T12-9 (0.1-10 μM) activates TLR1 mRNA and iNOS mRNA after Raw 264.7 cells are treated for 24 hours. CU-T12-9 (0.1-10 μM) activates TLR2 and IL-10 mRNA after Raw 264.7 cells are treated for 2 hours. CU-T12-9 (0.1-10 μM) activates TNF mRNA after Raw 264.7 cells are treated for 8 hours.Cell Cytotoxicity Assay Cell Line:HEK-Blue hTLR2 and Raw 264.7 macrophage cells Concentration:0.39, 0.78, 1.56, 3.125, 6.25, 12.5, 25, 50, and 100 μM Incubation Time:24 hours Result:No toxicity was seen up to 100 μM.RT-PCR Cell Line:Raw 264.7 cells Concentration:0.1, 1, 10 μM Incubation Time:24 hours for TLR1 and iNOS mRNA assay2 hours for TLR2 and IL-10 mRNA assay8 hours for TNF mRNA assay Result:Triggered TLR1 mRNA and iNOS mRNA at 24 hours dose-dependently.
