we designed and synthesized 50 N-benzylideneaniline compounds with the help of CADD. And subsequent in vitro studies leading to the optimized compound SMU-A0B13 with most potent inhibitory activity to TLR2 (IC50=18.21 ± 0.87 μM). Preliminary mechanism studies indicated that this TLR2 inhibitor can work through the NF-κB signaling pathway with high specificity and low toxicity, and can also efficiently
Toll样受体2(TLR2)可以识别病原体相关的分子模式以防御入侵的生物,并且已成为有吸引力的治疗靶标。直到今天,还没有在临床试验中开发出TLR2小分子拮抗剂。本文中,我们借助CADD设计并合成了50种 N-苄叉基苯胺化合物。随后进行的体外研究产生了对TLR2具有最强抑制活性的优化化合物SMU-A0B13(IC 50= 18.21±0.87μM)。初步的机制研究表明,该TLR2抑制剂可通过NF-κB信号通路发挥高特异性和低毒性的作用,并且还可以有效下调HEK-blue hTLR2,人PBMC和SHE中的炎性细胞因子,例如SEAP,TNF-α和NO。原始的264.7细胞系。此外,对接情况还表明SMU-A0B13可以很好地与TLR2-TIR(PDB:1FYW)活性域结合,这可能解释了其生物活性。
