摘要

采用微波四组份反应，以lawson、氟化芳醛、4,4,4-三氟乙酸乙酯和乙酸铵为原料，合成了新的氟化二氢吡萘醌类化合物。通过光谱方法对产物进行了全面表征，并对脂多糖刺激的RAW264.7巨噬细胞进行了抗炎活性评估。所有化合物均具有显著的抑制NO生成作用，IC50值在1.67 ± 0.02 ~ 28.81 ± 2.44 μM之间，无明显毒性。有趣的是，化合物8n对脂多糖（LPS）刺激的RAW264.7巨噬细胞的NO抑制活性最强，IC50值为1.67 ± 0.02 μM。此外，化合物8c、h、i、l显著降低lps刺激RAW264.7巨噬细胞中促炎因子IL-1β和IL-6的水平。这些结果表明这些化合物具有开发新型抗炎药的潜力。

Improved synthesis and anti-inflammatory activity of new fluorinated dihydropyranonaphthoquinone compounds

This study presents the synthesis of new fluorinated dihydropyranonapthoquinone compounds by means of microwave-prompted four-component reactions using lawson, fluorinated aromatic aldehydes, ethyl 4,4,4-trifluoroacetoacetate and ammonium acetate. The products were thoroughly characterized by spectroscopic methods and assessed for their anti-inflammatory activity in lipopolysaccharide-stimulated RAW264.7 macrophage cells. All synthesized compounds demonstrated notable inhibitory effects on NO production with IC₅₀ ranging from 1.67 ± 0.02 to 28.81 ± 2.44 μM without causing significant toxicity. Interestingly, compound 8n showed the most potent NO inhibitory activity in lipopolysaccharide (LPS)-stimulated RAW264.7 macrophage cells with IC₅₀ value of 1.67 ± 0.02 μM. Moreover, compounds 8c,h,i,l significantly decreased the levels of pro-inflammatory cytokines IL-1β and IL-6 in LPS-stimulated RAW264.7 macrophages. These results indicate the potential of these compounds as promising candidates for the development of new anti-inflammatory agents.
