bacterial fatty acid biosynthesis (FASII) pathway and are putative targets for antibacterial discovery. Several natural product KAS inhibitors have previously been reported, including thiolactomycin (TLM), which is produced by Nocardia spp. Here we describe the synthesis and characterization of optically pure 5R-thiolactomycin (TLM) analogues that show improved whole cell activity against bacterial strains
β-酮酰基-ACP合成酶(KAS)是参与II型细菌脂肪酸生物合成(FASII)途径的关键酶,并且是抗菌发现的假定靶标。先前已经报道了几种天然产物KAS抑制剂,包括由Nocardia spp生产的硫代乳霉素(TLM)。在这里,我们描述了光学纯的5 R-硫代催乳素(TLM)类似物的合成和表征,这些类似物显示出对细菌菌株包括耐甲氧西林金黄色葡萄球菌(MRSA)和优先病原体例如弗朗西斯菌tularensis和Burkholderia pseudomallei的完整细胞活性。此外,我们确定了具有MRSA和MRSA体内功效的TLM类似物肺炎克雷伯菌感染的动物模型。
