various biological activities of fisetin, we reported the design and synthesis of a series of fisetin derivatives which were also evaluated for their anti-inflammatory activities in J774A.1 macrophages. Most of the obtain derivatives could effectively inhibit the release of IL-6 and TNF-α in vitro experiments without cytotoxicity. The most promising compound 5b exhibited significant in vivo anti-inflammatory
急性肺损伤 (ALI) 是一种由炎症引起的常见且危及生命的疾病。然而,对于 ALI,有效的药物治疗很少见。天然产物被认为是药物发现的重要来源,这表明在天然产物中寻找新的抗炎药物是一种可行的方法。受非瑟酮各种生物活性的启发,我们报道了一系列非瑟酮衍生物的设计和合成,这些衍生物还评估了它们在 J774A.1 巨噬细胞中的抗炎活性。所得衍生物大部分在体外实验中均能有效抑制IL-6和TNF-α的释放,且无细胞毒性。最有希望的化合物5b在体内表现出显着LPS 诱导的小鼠 ALI 模型中的抗炎活性。总的来说,这项研究可以为治疗 ALI 提供新的候选者。
