Phthalide is a promising chemical scaffold and has been proved to show potent anti-inflammatory efficacy. In this study, three series, total of 31 novel phthalide derivatives were designed and synthesized, their anti-inflammatory activities were screened in vitro and in vivo. The anti-inflammatory activity of all the compounds were screened on LPS induced NO production to evaluating their inhibitory
邻苯二甲酰胺是一种有前途的化学支架,并已被证明具有有效的抗炎功效。在这项研究中,设计并合成了三个系列的31种新型邻苯二甲酸酯衍生物,并在体内和体外筛选了它们的抗炎活性。筛选了所有化合物对LPS诱导的NO产生的抗炎活性,以评估其抑制作用。结构-活性关系已经结束,最后3 - ((4 - ((4-氟苄基)氧基)苯基)(羟基)甲基)-5,7-二dimethoxyisobenzofuran -1(3H) -酮(化合物90) ,发现成为一种低毒的活性化合物,在使用IC 50的情况下在10μM时显示出95.23%的抑制率LPS诱导的一氧化氮过表达值为0.76μM。初步的机理研究表明,化合物9o通过积累ROS激活了Nrf2 / HO-1信号通路,并阻断了NF-κB/ MAPK信号通路。体内抗炎活性表明,化合物9o对佐剂诱导的大鼠关节炎模型具有明显的治疗作用。
