中文摘要:
      以4-氨基-3-碘苯甲酸甲酯为原料,经过一系列反应得到苯甲酸衍生物类流感病毒神经氨酸酶抑制剂I-IV,并经化合物II衍生得到化合物V-VII,结构经1HNMR,13CNMR,MS确证;用化学荧光法测定抑制率,测试选用流感病毒菌株H3N2(California/04),H1N1(California/99)和B(Shanghai/02),结果显示:在I-IV中,苯环C3位置侧链越大,化合物的活性越低;V-VII中,在苯环侧链α位的碳上引入羟基后比在β位碳上单羟基的化合物活性增强,这表明α位的碳上电子环境的变化对活性有较大影响;在苯环侧链α位的碳上含有单羟基的化合物VII具有对A型流感病毒最强的活性。
英文摘要:
      A kind of kind of benzoic acid derivatives influenza neuraminidase inhibitors I to IV were prepared from the starting materials of 4-amino-3-iodine benzoic acid through a series of reactions , the compounds V - VII derivatived from compound II , and the structures were characterized by 1H NMR,13C NMR and MS.Inhibition rate determined by chemical fluorescence, and the activity test was performed by the influenza virus strains H3N2 (California / 04), H1N1 (California / 99) and B (Shanghai / 02), the results showed: Among the compounds I - IV, the greater side chain at C3 position,the lower activity of compounds; Among the compounds V - VII, introduction of hydroxyl on the α carbon in the side chains of benzene ring, the inhibitory activity stronger than single hydroxyl on β carbon, which suggested that the change of electronic environment on the α carbon had a greater influence on activity; Compound VIIcontaining single hydroxyl at α carbon in side chains of benzene ring possessed the strongest activity of type A influenza virus.
