this active compound, a series of 2-substituted quinazolines was synthesized and evaluated in several antibacterial assays. One such compound (22) displayed improved broad-spectrum antibacterial activity against a variety of bacterial strains. This molecule also inhibited transcription/translation of bacterial RNA, suggesting a mechanism for its antibiotic effects. Structure-activity relationship studies
内部化合物库的高通量筛选导致发现了一种新型抗菌剂化合物1(MIC:针对化脓性链球菌的12-25 microM)。为了提高该活性化合物的活性,合成了一系列2-取代的喹唑啉并在几种抗菌试验中进行了评估。一种这样的化合物(22)显示出对多种细菌菌株的改善的广谱抗菌活性。该分子还抑制细菌RNA的转录/翻译,提示了其抗菌作用的机制。22种化合物的构效关系研究导致了另外24种化合物的合成。尽管发现这些分子中的一些在细菌生长测定中具有活性,但没有一个比22更有力。测试了化合物22治愈系统性K的能力。
