  摘要：

  合成了一系列新的2-甲氧基-2'-羟基苯甲腈衍生物及其硫代类似物，并通过红外，核磁共振和元素分析对其进行了表征。这些化合物进行了调查其体外抗分支杆菌活性针对结核分枝杆菌331 / 88，鸟分枝杆菌330 / 88，堪萨斯分枝杆菌235 / 80，临床分离堪萨斯分枝6509 / 96和充当能力体外异柠檬酸裂解酶抑制剂。最好的ICL抑制剂是硫代苯甲腈类的两种化合物（8f，8m），其显示出与标准化合物3-硝基丙酸相同的抑制潜能。另外，具有5-Cl和4'或5'Cl / Br取代的苯甲酰苯胺衍生物6h，6k和6l表现出最佳的抗分枝杆菌性能。对于所有测试的硫代苯甲腈衍生物，在NMR谱图中观察到两个构象异构体，这很可能是由于C–N键的旋转受阻所致。
