In an effort to identify novel anti-inflammatory compounds, a series of flavone derivatives were synthesized and biologically evaluated for their inhibitory effects on the production of nitric oxide (NO) and prostaglandin E2 (PGE2), representative pro-inflammatory mediators, in LPS-induced RAW 264.7 cells. Their structure-activity relationship was also investigated. In particular, we found that compound
为了鉴定新型抗炎化合物,合成了一系列黄酮衍生物,并对其在LPS-中对代表性的促炎性介质一氧化氮(NO)和前列腺素E2(PGE2)产生的抑制作用进行了生物学评估。诱导的RAW 264.7细胞。还研究了它们的构效关系。尤其是,我们发现与木犀草素(一种被称为强效抗炎剂的天然黄酮)相比,化合物3g对PGE2的产生显示出更强的抑制活性,对NO生成具有类似的抑制活性,并且细胞毒性也较弱。
