A series of dihydroflavonol derivatives (4a–4l) were synthesized from chalcones via classical Algar–Flynn–Oyamada (AFO) reaction and characterized on the basis of spectroscopic analyses. All synthesized compounds were evaluated for their inhibitory activity against the pro-inflammatory-inducible TNF-alpha, IL-1beta, and IL-6 in lipopolysaccharide (LPS)-stimulated RAW 264.7 cell lines and showed various
通过经典的阿尔加-弗林-奥马达(AFO)反应从查耳酮合成了一系列二氢黄酮醇衍生物(4a - 4l),并在光谱分析的基础上进行了表征。评估了所有合成的化合物对脂多糖(LPS)刺激的RAW 264.7细胞系中促炎性诱导的TNF-α,IL-1beta和IL-6的抑制活性,并显示了多种功效。此外,通过使用两个经典模型选择化合物4d和4k来检查其体内抗炎活性。此处化合物4k与阿司匹林和美洛昔康这两个参考文献相比,在小鼠耳部肿胀模型中显示出最大的抗炎活性,抑制率为32.98%,在大鼠爪水肿模型中,间隔2小时的抑制作用为40.06%。在较低剂量下观察到类似的效果。此外,将化合物4k与环氧合酶-2对接以验证获得的药理数据,并为观察到的抗炎活性提供可理解的证据。
