Various structural analogs of N-acetylmuramyl-l-alanyl-d-isoglutamine, which had been shown to be the minimum structure required for the immunoadjuvant activity of bacterial cell walls, were synthesized in order to investigate in more detail the relationship between the activity and chemical structures. Particularly, the compounds of the structures corresponding to the cell walls of special bacteria without immunoadjuvant activity were prepared in this study. Several novel procedures including the preparation of a branched glutamyl peptide were newly exploited to accomplish the syntheses of muramyl peptides with complicated structures. As a result of this synthetic study, new informations were obtained on the structural requirement for the immunoadjucant activity.
N-acetylmuramyl-l-alanyl-d-isoglutamine 是细菌细胞壁具有免疫佐剂活性所需的最小结构,为了更详细地研究这种活性与化学结构之间的关系,我们合成了 N-acetylmuramyl-l-alanyl-d-isoglutamine 的各种结构类似物。本研究特别制备了与无免疫佐剂活性的特殊细菌细胞壁结构相对应的化合物。本研究还采用了包括制备支链谷氨酰肽在内的几种新方法,合成了结构复杂的氨甲酰肽。通过这项合成研究,我们获得了有关免疫佐剂活性结构要求的新信息。
