Aberrant activation of NLRP3 inflammasome is present in a subset of acute and chronic inflammatory diseases. The NLRP3 inflammasome has been recognized as an attractive therapeutic target for developing novel and specific anti-inflammatory inhibitors. Cellular structure-activity relationship-guided optimization resulted in the identification of 4-oxo-2-thioxo-thiazolidinone derivative 9 as a selective and direct small-molecule inhibitor of NLRP3 with IC of 2.4 μM, possessing favorable ex vivo and in vivo pharmacokinetic properties. Compound 9 may represent a lead for the development of anti-inflammatory therapeutics for treating NLRP3-driven diseases.
NLRP3 炎性小体的异常激活存在于一部分急性和慢性炎症性疾病中。NLRP3 炎性小体已被认为是开发新型、特异抗炎抑制剂的一个有吸引力的治疗靶点。基于细胞结构-活性关系的优化，鉴定出 4-氧代-2-硫代-噻唑烷酮衍生物 9 是 NLRP3 的选择性和直接小分子抑制剂，IC 为 2.4μM，具有良好的体外和体内药代动力学特性。化合物 9 可能代表了一种用于治疗 NLRP3 驱动疾病的抗炎治疗药物的先导化合物。
