inflammasome activation plays a critical role in inflammation and its related disorders. Herein we report a hit-to-lead effort resulting in the discovery of a novel and potent class of NLRP3 inflammasome inhibitors. Among these, the most potent lead 40 exhibited improved inhibitory potency and almost no toxicity. Further mechanistic study indicated that compound 40 inhibited the NLRP3 inflammasome activation
NLRP3 炎症小体激活在炎症及其相关疾病中起着关键作用。在此,我们报告了一项领先的努力,导致发现了一类新型有效的 NLRP3 炎症小体抑制剂。其中,最有效的铅40表现出提高的抑制效力并且几乎没有毒性。进一步的机理研究表明,化合物40通过抑制 ROS 的产生来抑制 NLRP3 炎症小体的激活。更重要的是,用40治疗对 LPS 诱导的败血症和 DSS 诱导的结肠炎显示出显着的治疗效果。这项研究鼓励进一步开发基于这种化学支架的更有效的抑制剂,并提供一种化学工具来识别其细胞结合靶点。
