方法A
4-(4′-碘苯氧基)苯胺的制备
将浓盐酸(6.04ml,68.4毫摩尔)的乙醇(25ml)/水(25ml)溶液,在50分钟内滴加到机械搅拌并回流的4-(4′-碘苯氧基)硝基苯(23.34g,68.4毫摩尔)和铁屑(11.46g,205毫摩尔,3.0当量)的乙醇(150ml)/水(150ml)的悬浮液中。1小时后使混合物冷却至室温并蒸发至体积为约200ml。用10%氢氧化钠水溶液将混合物碱化至pH约11,然后加入水(200ml)和乙酸乙酯(250ml)。水溶液部分进一步用乙酸乙酯(2×50ml)萃取,合并的有机相用水(2×125ml)、盐水(50ml)洗涤,干燥(MgSO),过滤并蒸发,得到20.25g棕色半固体。闪式柱色谱(0-10%EtOAc/CH  Cl为洗脱液)纯化,得到13.40g(62.9%)产物,为浅棕色晶体。
实施例7:N-[[2-(4′-氯苯氧基)苯基]吡啶-5-基]-2-氰基-3-环丙基-3-羟基-丙-2-烯酰胺。
用实施例1所述的相同条件并对步骤C和D作实施例6所述的修改,由2-氯-5-硝基吡啶和4-氯苯酚制备N-[[2-(4′-氯苯氧基)苯基]吡啶-5-基]-2-氰基-3-环丙基-3-羟基-丙-2-烯酰胺。

生物化学试验方法
试验1
角叉菜胶大鼠爪水肿(PO-R)
给几组大鼠(n=6-12,雄性CFHB,体重范围160-180mg)以50mg/kg的剂量口服试验化合物或对照载体,1小时后,在大鼠右后爪垫注射溶于0.2ml盐水中的1mg角叉菜胶。给对侧爪注射对照盐水。3小时后评定爪水肿反应。
试验2
迟发型超敏反应小鼠爪水肿(DTH-M)
给几组小鼠(n=8-10,雄性CD-1,体重范围25-30g)皮下注射0.2ml盐水/弗氏完全佐剂(FCA)乳液中的1mg甲基化牛血清清蛋白(MBSA),使小鼠致敏。给阴性对照组注射盐水/FCA乳液。在致敏后第七天,用0.05ml盐水中的0.1mg  MBSA注射小鼠右后爪垫,24小时后评定DTH爪水肿反应。给对侧爪注射对照盐水。在第四、六天,各口服一次试验化合物或对照载体,第七天给药两次,即在注射MBSA  1小时前和6小时后给药。
试验3
迟发型超敏反应大鼠爪水肿(DTH-R)
给几组大鼠(n=8-12,雄性CFHB,体重范围160-180mg)皮下尾底注射0.1ml  FCA,使其致敏。给阴性对照组注射弗氏不完全佐剂。在致敏后第七天,用0.2ml盐水中的0.4mg结核分支杆菌浸出物抗原注射大鼠右后爪垫,24小时后评定DTH爪水肿反应。给对侧爪注射对照盐水。
在第四、五、六天每天口服试验化合物一次,第七天口服两次,即注射抗原1小时前和6小时后各口服一次。
将这些试验结果列于下表。所给出的口服剂量以mg/kg为单位。
