modifying the structure of tetracyclic quinobenzothiazinium derivatives has been developed, allowing introduction of various substituents at different positions of the benzene ring. The method consists of reacting appropriate aniline derivatives with 5,12-(dimethyl)thioquinantrenediinium bis-chloride. A series of new quinobenzothiazine derivatives was obtained with propyl, allyl, propargyl and benzyl substituents
开发了一种修饰四环苯并噻嗪衍生物结构的新方法,允许在苯环的不同位置引入各种取代基。该方法包括使合适的苯胺衍生物与 5,12-(二甲基)硫代喹蒽二铵双氯化物反应。得到了一系列在9、10和11位分别带有丙基、烯丙基、炔丙基和苄基取代基的新的喹啉基苯并噻嗪衍生物。通过1H和13C NMR(HSQC,HMBC)和X-射线分析分析获得的化合物的结构。所有化合物均针对参考菌株金黄色葡萄球菌 ATCC 29213 和粪肠球菌 ATCC 29212 以及耐甲氧西林金黄色葡萄球菌 (MRSA) 和耐万古霉素粪肠球菌 (VRE) 的多重耐药临床分离株的代表进行了测试。此外,所有化合物均在体外针对耻垢分枝杆菌 ATCC 700084 和海分枝杆菌 CAMP 5644 进行了评估。9-Benzyloxy-5-methyl-12H-quino [3,4-b][1,4]benzothiazinium chloride
