摘要
以4-羟基香豆素为原料出发,合成得到3个系列共22个香豆素衍生物,其中8个衍生物未见文献报道,并采用小鼠巨噬细胞模型对其体外抗炎活性及作用机制进行初步研究。结果表明,大部分衍生物均可显著抑制促炎因子NO的生成,其中化合物2e、2f、2g、2h、2i、2j、4e和4f的抗炎活性优于阳性对照药物地塞米松。进一步实验发现,化合物2h和4f可显著抑制RAW264.7巨噬细胞内促炎因子IL-6、TNF-α和IL-1β的生成,可作为先导化合物进行深入研究。
In this work,starting from 4-hydroxycoumarin,three series of 22 coumarin derivatives,among which 8 have not been reported in the literature,were synthesized and their in vitro anti-inflammatory activities and mechanisms of action were preliminarily investigated using mouse macrophage model.The results showed that most of the derivatives could significantly inhibit the production of pro-inflammatory factor NO,with compounds 2e,2f,2g,2h,2i,2j,4e,and 4f showing better anti-inflammatory activity than the positive control drug dexamethasone.Further experiments showed that compounds 2h and 4f significantly inhibited the production of pro-inflammatory factors IL-6,TNF-α and IL-1β in RAW264.7 macrophages,and could,therefore,be used as lead compounds for further studies.
