[Structure-functional study of glycosaminylmuramoyl peptides. The effect of chemical modification of N-acetylglucosaminyl-N-acetylmuramoyldipeptide on its immunomodulating properties in vivo and in vitro].
The structure-function relationships in a series of synthetic glucosaminylmuramyl peptides--glycopeptide adjuvants of the bacterial origin--have been investigated. Modification of the N-acetylglucosaminyl-(beta 1-4)-N-acetylmuramyl-L-alanyl-D-isoglutamine (GMDP) molecule affects its adjuvant and pyrogenic activity in vivo. GMDP is shown to readily stimulate the synthesis of the IgG2a and IgG3 of the immunoglobulin subclasses upon the secondary immune response to the protein antigen. The adjuvant effect correlates with the comitogenic test of the reaction of splenocytes blast-transformation in the presence of B-cell mitogen. No direct dependence has been revealed between the level of the glycopeptides adjuvant action and their effect on the IL-1 production by macrophages.
