  摘要：

  一系列N-烷基-3-(烷基氨基)吡嗪-2-羧酰胺及其N-烷基-3-氯吡嗪-2-羧酰胺前体被制备出来。所有化合物均通过分析方法进行表征，并测试了其抗菌和抗病毒活性。在针对结核分枝杆菌（Mycobacterium tuberculosis H37Rv）的抗分枝杆菌MIC值中，效果最好的化合物3-(己氨基)-、3-(庚氨基)-和3-(辛氨基)-N-甲基吡嗪-2-羧酰胺14-16的MIC值为25微克/毫升。这些化合物抑制了菠菜叶绿体中的光系统II光合作用电子传输（PET）。这种活性与化合物的亲脂性密切相关。为了有效抑制PET，N-烷基-3-(烷基氨基)吡嗪-2-羧酰胺分子中3-(烷基氨基)取代基中的较长烷基链比两条较短的烷基链更有利。

  摘要：

  制备了一系列取代的N-苄基-3-氯吡嗪-2-羧酰胺，它们是先前制备的5-氯和6-氯衍生物的位置异构体。在酰氯的氨解过程中，在某些情况下，用苄基氨基部分同时取代氯会产生N-苄基-3-（苄基氨基）吡嗪-2-羧酰胺作为副产物。尽管最初没有计划，但修改了反应条件以填充该双取代系列。测试了最终化合物对四种分枝杆菌菌株的抵抗力。N-（2-甲基苄基）-3-（（2-甲基苄基）氨基）吡嗪-2-羧酰胺（1a）和N-（3,4-二氯苄基）-3-（（3,4-二氯苄基）氨基）吡嗪-2-羧酰胺（9a）被证明对结核分枝杆菌H37Rv最有效，MIC = 12.5μg·mL-1。筛选化合物的抗菌活性。活性最高的化合物是抗金黄色葡萄球菌的3-氯-N-（2-氯苄基）吡嗪-2-羧酰胺（5），MIC = 7.81μM，表皮葡萄球菌，MIC = 15.62μM。评估了HepG2的最具活性的化合物的细胞毒性。但是，没有发现明显的毒性。化
