摘　　要：目的设计合成(E)-3-苯基丙烯酸衍生物,寻找具有较强抗炎活性的化合物。方法对先导化合物(E)-3-[3-甲氧基-4-(3-苯基)丙烯酰氧基]苯基丙烯酸(1)进行结构修饰,将其分别与脂肪(环)醇、芳香醇、芳杂环醇成酯,与脂肪(环)胺、芳香胺、芳杂环胺成酰胺;以二甲苯致小鼠耳肿胀模型考察不同类型的酯和酰胺的抗炎活性。结果合成了8个未见文献报道的(E)-3-苯基丙烯酸衍生物,经红外光谱和核磁共振氢谱确证其结构;目标化合物3a、3b、3c具有一定的抗炎活性,抑制率分别为31.3%、40.3%、31.7%。结论所设计的合成方法可应用于较大分子酯类和酰胺类的合成;在本实验条件下,(E)-3-苯基丙烯酰胺类目标化合物3a、3b、3c具有抗炎作用,高于先导化合物1,(E)-3-苯基丙烯酸酯类目标化合物几乎无抗炎活性。Objective To design and synthesize（E）-3-phenylpropenoic acid derivatives and study their antiinflammatory activities. Methods The target compounds were synthesized from （E）-3-[ 3-methoxy-4-（3- phenyl） acryloxy] phenylpropenoic acid via dehydration and their biological activities were evaluated with the model of xylene-induced ear edema in mice. Results Eight novel compounds were obtained and their structures were characterized by ^1H-NMR and IR spectra. Pharmacological tests showed the target compound 3a,3b, 3c exhibited certain anti-inflammatory activities, the inhibitory rate were 31.3 %, 40.3%, 31.7% respectively. Conclusions The synthetic method can be applied to the synthesis of esters and amides ; the anti-inflammation activities of target compounds 3a, 3b, 3c are higher than that of compound 1.
