The synthesis of a series of alkyl (having from C6 to C20 aglycones), cyclohexyl, and cyclohexylalkyl alpha-d-mannopyranosides, 6-deoxygenated analogs, thioglycosides, and sulfones derived thereof, is reported. Here, under the in vitro assay conditions used, none of the 15 tested compounds acted as an inhibitor of the mannose transfer catalyzed by the enzymes present in mycobacterial membrane and cell
据报道,合成了一系列烷基(具有从C 6至C 20的糖苷配基),环己基和环己基烷基α-d-甘露吡喃糖苷,6-脱氧类似物,硫代糖苷及其衍生的砜。在此,在所用的体外测定条件下,15种被测化合物均未充当分枝杆菌膜和细胞壁组分中存在的酶催化的甘露糖转移的抑制剂。在分枝杆菌甘露糖基转移酶反应中,包含较短的脂族,最多8个碳原子长的线性或环状糖苷的甘露吡喃糖苷用作受体底物。与砜相反,该硫糖苷表现出相似的行为,而后者基本上未被分枝杆菌酶所识别。6-脱氧糖苷未被酶处理,
