lidin-4-one analogs, designed as hybrids of CY09 and JC121, were investigated as inhibitors of NLRP3 inflammasome activation. Among them, compounds 34 and 36 were identified as promising NLRP3 inhibitors by measuring the amount of active caspase-1 p20 and IL-1β produced by NLRP3 inflammasome activation. Further studies indicated that both compounds inhibited NLRP3 inflammasome assembly by reducing
一系列N-苄基 5-(4-sulfamoylbenzylidene-2-thioxothiazolidin-4-one 类似物,设计为 CY09 和 JC121 的杂合体,被研究作为 NLRP3 炎性体激活的抑制剂。其中,化合物34和36被确定为有前景的化合物NLRP3 抑制剂通过测量由 NLRP3 炎性体激活产生的活性 caspase-1 p20 和 IL-1β 的量。进一步的研究表明,这两种化合物通过减少 NLRP3 和 ASC 寡聚体斑点的形成来抑制 NLRP3 炎性体组装,并选择性地仅抑制 NLRP3 炎性体活化和不是其他炎症小体,例如 NLRC4 和 AIM2。
