caspase-1 may provide a potential therapeutic strategy for the treatment of chronic inflammatory diseases. Here we have reported structure-based design, synthesis and biological evaluation of 2,4-diaminopyrimidine derivatives (6a-6w) as potential caspase-1 inhibitors. Six compounds 6m, 6n, 6o, 6p, 6q and 6r showed significant enzymatic inhibition with IC50 ranging from 0.022 to 0.078 µM. These compounds
白介素-1β转化酶通过使促炎性细胞因子IL-1β,IL-18和IL-33成熟,从而导致多种炎症和自身免疫性疾病。因此,抑制caspase-1可能为慢性炎性疾病的治疗提供潜在的治疗策略。在这里,我们已经报告了作为潜在caspase-1抑制剂的2,4-二氨基嘧啶衍生物(6a-6w)的基于结构的设计,合成和生物学评估。六种化合物6m,6n,6o,6p,6q和6r对IC 5 0表现出明显的酶抑制作用范围为0.022至0.078 µM。这些化合物在亚微摩尔浓度下也显示出优异的细胞效价。此外,分子对接研究提供了对caspase-1抑制特异的有用的结合见解。所有这些结果表明,化合物6m,6n和6o可能是开发新型caspase-1抑制剂作为抗炎药的潜在原因。
