title: [Synthesis and protective activity of beta-glycosides of N-acetylmuramyl-L-alanyl-D-isoglutamine with alkylalicyclic and arylaliphatic aglycons].
abstract: The following glycosides of N-acetylmuramyl-L-alanyl-D-isoglutamine (MDP) were synthesized: beta-4-tert-butylcyclohexyl MDP, beta-2-(adamant-1-yl)ethyl MDP, beta-2,2-diphenylethyl MDP, and 3-2-(p-biphenyl)ethyl MDP. The starting peracetylated beta-N-acetylglucosaminides were prepared by the oxazoline method. They were converted into 4,6-O-isopropylidene-N-acetyl-D-muramic acids, which were coupled with L-Ala-D-Glu(NH2)OBn. The target glycopeptides were obtained after their deprotection. The stimulation of the antiinfection resistance of mice against Staphylococcus aureus by the MDP glycosides was studied.
