lipophilic adamantane on N- or C-terminus through a glycolyl or hydroxyisobutyryl linker. Adjuvant activities of synthesized compounds were investigated in the mouse model using ovalbumin as an antigen. Their activities were compared to the previously described mannosylated adamantane-containing desmuramyl peptide and peptidoglycan monomer. Tested compounds exhibited adjuvant activity and the strongest enhancement
村酰二肽是具有佐剂性质的肽聚糖的最小结构。更换N-乙酰基村m基部分和亲脂性的增加是制备具有改善的药理学性质的mu基二肽类似物的重要方法。存在于免疫感受态细胞上的甘露糖受体是模式识别受体,通过甘露糖配体的结合,它们会影响免疫系统。在这里,我们介绍了新型甘露糖基去村酰胺肽衍生物的设计,合成和生物学评估。甘露糖通过乙醇酰基或羟基异丁酰基接头与在N-或C-末端上含有亲脂性金刚烷的二肽偶联。使用卵清蛋白作为抗原,在小鼠模型中研究了合成化合物的佐剂活性。将它们的活性与先前描述的含甘露糖基的金刚烷的去马甲酰肽和肽聚糖单体进行比较。21(Man-OCH 2 - ᴅ-(1-Ad)Gly-ʟ-Ala-ᴅ-isoGln)。
