than their decylated analogs. Thioglycosides were more efficient than glycosides and sulfones. The activity of the 6-O-ether derivatives was higher than that of their ester counterparts. Seven derivatives with dodecyl chain linked (thio)glycosidically or etherically at C-6 showed high efficacy against both P. larvae strains (MICs ranged from 12.5 μM to 50 μM). Their efficacies were similar or much higher
类芽孢杆菌幼虫是美洲臭虫 (AFB) 的病原体,AFB 是影响蜜蜂幼虫和蛹发育的最严重的细菌性疾病。在这项研究中,评估了从具有 C10 或 C12 烷基链的 d-甘露糖、d-葡萄糖和 d-半乳糖衍生的 24 种(硫代)糖苷、糖基砜、6-O-酯和醚的文库的抗菌功效针对两种 P. 幼虫菌株。以最小抑制浓度 (MIC) 确定的受试化合物的功效差异很大。通常,发现十二烷基衍生物比它们的癸基化类似物更有效。硫苷比苷和砜更有效。6-O-醚衍生物的活性高于它们的酯对应物。在 C-6 处具有十二烷基链(硫代)糖苷或醚连接的七种衍生物显示出对两种 P. 幼虫菌株的高效(MIC 范围从 12.5 μM 到 50 μM)。它们的功效与已知对 P. larvae-lauric acid、monolaurin 和蜜蜂幼虫食物成分、10-hydroxy-2-decenoic acid 和 sebacic acid(MIC
