potential option for the development of novel therapies. In this study, we designed and synthesized a total of fifty-eight novel amide/sulfonamide derivatives based on our previously reported anti-inflammatory compounds. The anti-inflammatory activities of these compounds were evaluated upon LPS-stimulated J774A.1 cells. Compounds 11a, 11b, 11c, and 11d potently reduced the release of IL-6 and TNF-α, and
炎症的不平衡调节与多种疾病有关,使得抗炎成为开发新疗法的潜在选择。在这项研究中,我们根据之前报道的抗炎化合物设计并合成了总共 58 种新型酰胺/磺酰胺衍生物。在 LPS 刺激的 J774A.1 细胞上评估了这些化合物的抗炎活性。化合物11a、11b、11c和11d有效减少J774A.1细胞中IL-6和TNF-α的释放,并降低细胞因子的mRNA水平。最活跃的化合物11d,对于IL-6抑制的IC 50值为0.61 μM,对于TNF-α抑制的IC 50 值为4.34 μM,恢复了IκB α并抑制磷酸化p65转位到细胞核中。体内评估表明,11d改善了 LPS 诱导的 ALI,并减轻了 DSS 诱导的小鼠溃疡性结肠炎。总之,这些结果表明化合物11d可以成为开发抗 ALI 和溃疡性结肠炎抗炎药物的新先导结构。
