Diprovocim is a potent TLR1/TLR2 agonist. Diprovocim elicits full agonist activity in human THP-1 cells (EC 50 =110 pM). Diprovocim stimulates the release of TNF-α from mouse macrophages (EC 50 =1.3 nM). Diprovocim activates downstream MAPK and NF-κB signaling pathway. Diprovocim displays strong adjuvant activity in mice, particularly abetting cellular immune responses.

体外研究(In Vitro)
Diprovocim (在 THP-1 细胞中为 5 nM, 在小鼠腹膜巨噬细胞中为 500 nM; 15-120 分钟) 诱导 IKKα、IKKβ、p38、JNK 和 ERK 的磷酸化,以及 IκBα 的降解。 Diprovocim (0.01-10000 nM; 4 小时) 诱导 THP-1 细胞 (EC50=110 pM)、人外周血单核细胞 (PBMC) (EC50=875 pM) 和小鼠腹腔巨噬细胞 (EC50=1.3 nM) 和骨髓来源的树突状细胞 (BMDC) (EC50=6.7 nM) 产生剂量依赖性 TNF。 除 TNF 外,Diprovocim 还诱导小鼠 BMDC 产生 IL-6。 has not independently confirmed the accuracy of these methods.
