CU-T12-9性质、用途与生产工艺

生物活性 CU-T12-9 是一种特异性 TLR1/2 激动剂，EC50 为 52.9 nM。CU-T12-9 既激活先天免疫系统，又激活适应性免疫系统。CU-T12-9 选择性激活 TLR1/2 异二聚体而对 TLR2/6 没有作用。CU-T12-9 通过促进 TLR1 和 TLR2 二聚而激活 NF-κB 信号，致使下游 TNF-α，IL-10，和 iNOS 增加，从而提高身体的免疫反应。

体外研究

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.
