We report the chemical synthesis of a series of disaccharides of arabinofuranose with a glycosidic sulfur linker as mimics of the acceptor for arabinofuranosyltransferases with and without using any activator to avoid any complex reactions. These analogs were tested for in vitro activityagainstMTB strain H37Ra and 3 MAC clinical isolates. MICs were determined using a colorimetric microdilution broth
我们报告了一系列带有糖苷硫接头的阿拉伯呋喃糖二糖的化学合成,作为阿拉伯呋喃基转移酶受体的模拟物,使用或不使用任何激活剂以避免任何复杂反应。测试了这些类似物对 MTB 菌株 H37Ra 和 3 个 MAC 临床分离株的体外活性。MIC 使用比色微量稀释肉汤测定来确定。杀菌活性是用 7 天的杀菌曲线研究的。在 Mono Mac 6 (MM6) 人单核细胞系中测定了针对 MTB H37Ra 的细胞内活性。
