Studies have shown that the abnormal activation of the NLRP3 inflammasome is involved in a variety of inflammatory-based diseases. In this study, a high content screening model targeting the activation of inflammasome was first established and pterostilbene was discovered as the active scaffold. Based on this finding, total of 50 pterostilbene derivatives were then designed and synthesized. Among them
研究表明NLRP3炎症小体的异常激活与多种炎症性疾病有关。本研究首次建立了针对炎症小体激活的高内涵筛选模型,并发现紫檀芪作为活性支架。基于这一发现,设计并合成了总共50种紫檀芪衍生物。其中,化合物47被发现是抑制细胞焦亡最好的一种[抑制率(IR) = 73.09% at 10 μM],表现出低毒高效[针对白细胞介素-1β(IL-1β):半最大抑制浓度(IC 50 ) = 0.56 μM]。进一步的研究表明,化合物47通过靶向NLRP3影响NLRP3炎症小体的组装。体内生物活性表明,该化合物可显着减轻右旋糖酐硫酸钠(DSS)诱导的小鼠结肠炎。总的来说,我们的研究提供了一种直接靶向NLRP3蛋白的新型先导化合物,值得进一步研究和结构优化。
