Effects of muramyl dipeptide glycosides on lymphocyte proliferation and production of interleukin-2

We studied the effect of new muramyl dipeptide glycosides with different structure of aglycon and configuration glycoside bond on spontaneous and mitogen-induced proliferation of mouse splenocytes and production of interleukin-2 by these cells. Biological activity of muramyl dipeptide beta-glycosides with aliphatic, carbocyclic, adamantile, and phenol aglycons is higher than that of the original compound, while alpha-glycosylation decreases the immunostimulating effect of this glycopeptide.
