the experimental system utilized in investigating the correlation between the chemical structures of muramyl peptides and their protective activities in the sepsis type of systemic infections caused by escherichia coli was applied in evaluating the enhancement of resistance to infection induced by 32 synthetic glycopeptide analogs , including 6-o-acyl derivatives and 1-alpha-o-benzyl derivatives of muramyl dipeptide ( n-acetyl muramyl-l-alanyl-d-isoglutamine ) .
