NLRP3 inflammasome plays critical roles in a variety of human diseases and represents a promising drug target. In this study, we established the in vivo functional activities of JC124, a previously identified NLRP3 inflammasome inhibitor from our group, in mouse models of Alzheimer’s disease and acute myocardial infarction. To understand the chemical space of this lead structure, a series of analogues
NLRP3炎性小体在多种人类疾病中起着至关重要的作用,并代表着有希望的药物靶标。在这项研究中,我们在阿尔茨海默氏病和急性心肌梗死的小鼠模型中建立了JC124的体内功能活性,JC124是我们小组中先前鉴定的NLRP3炎性体抑制剂。为了了解这种铅结构的化学空间,设计,合成了一系列类似物并对其进行了生物学表征。结果揭示了JC124的苯甲酰胺部分的两个取代基的关键作用。另一方面,对JC124的磺酰胺部分的修饰具有良好的耐受性。两种新的铅化合物14和17被鉴定具有改善的抑制效力(IC 50值分别为0.55±0.091和0.42±0.080μM)。进一步的表征证实了它们的选择性和体内靶标结合。总的来说,该结果强烈鼓励进一步开发基于该化学支架的更有效的类似物。
