  摘要：

  Hexyl, octyl, and cyclohexyl beta-glycosides and heptyl and cyclohexyl alpha-glycosides of muramyl dipeptide (MDP) were synthesized. Tests in vitro and in vivo revealed lower immunostimulating activities of MDP alpha-glycosides in comparison with the corresponding beta-glycosides and MDP itself. In the case of alkyl beta-glycosides, differences in hydrocarbon chain lengths (C-4-C-8) and in aglycone (aliphatic chain and aliphatic or aromatic ring) exerted no substantial effect on the immunostimulating activity.
