Mycobacterium tuberculosis, Mycobacterium kansasii and two types of Mycobacterium avium. The series comprised of N-substituted 3-aminopyrazine-2,5-dicarbonitriles derived from 3-chloropyrazine-2,5-dicarbonitrile by nucleophilic substitution of chlorine by various non-aromatic amines (alkylamines, cycloalkylamines and heterocyclic amines). Noteworthy antimycobacterial activity against M. tuberculosis was found
合成了一系列与吡嗪酰胺有关的14种新化合物,并通过分析数据进行了表征,并筛选了针对结核分枝杆菌,堪萨斯分枝杆菌和两种鸟分枝杆菌的体外抗分枝杆菌活性。该系列由通过各种非芳族胺(烷基胺,环烷基胺和杂环胺)对氯的亲核取代而衍生自3-氯吡嗪-2,5-二腈的N-取代的3-氨基吡嗪-2,5-二腈。在烷基氨基衍生物中发现了值得注意的针对结核分枝杆菌的抗分枝杆菌活性,例如3-(庚基氨基)吡嗪-2,5-二甲腈抑制的结核分枝杆菌。在MIC = 51μmol/ L时。3-(己基氨基)吡嗪-2,5-二碳腈在MIC = 218μmol / L时抑制堪萨斯分枝杆菌。讨论了基本的结构-活动关系。包括该系列中计算出的和实验确定的亲脂性参数之间的比较。
