24 derivatives (5a–x) derived from natural pyranochalcones (I and II) were designed and evaluated for their inhibitory potency on the production of nitric oxide (NO) in LPS-stimulated RAW264.7 cells. Among them, four compounds (5b, 5d, 5f, and 5h) exhibited more potent inhibitory effects on iNOS activity and iNOS-mediated NO production than a positive control indomethacin. Furthermore, 5b could significantly
设计并评估了24种衍生自天然吡喃并二氢呋喃酮(I和II)的衍生物(5a – x)对LPS刺激的RAW264.7细胞中一氧化氮(NO)产生的抑制作用。其中,与阳性对照消炎痛相比,四种化合物(5b,5d,5f和5h)对iNOS活性和iNOS介导的NO产生更有效的抑制作用。而且5b与吲哚美辛相比,剂量为10 mg / kg / day的大鼠可显着抑制角叉菜胶诱发的后足水肿的进展,并通过关节炎评分和关节H&E染色验证了剂量依赖性地改善了佐剂诱发的关节炎(AIA)的发展。此外,对接研究证实5b是与鼠iNOS活性位点结合的iNOS抑制剂。
