[Immunostimulating properties of synthetic derivatives of muramyl dipeptide and glucosaminyl muramyl dipeptide in vitro].
Production of tumor necrosis factor (TNF) and interleukin-1 (IL-1) by macrophages of the spleen and peritoneal exudate of mice as well as cytotoxic factors (CFs) by murine splenocytes after in vitro activation was estimated. All the derivatives of muramyldipeptide (MDP) and glucosaminylmuramyldipeptide (GMDP) were able to induce production of TNF and CFs. In the presence of lipopolysaccharide (LPS), the effect was always higher. The response of the spleen macrophages to the effect of the preparations was higher than that of the peritoneal ones and ++non-fractionated splenocytes. GMDP and GMDP4 especially in the presence of LPS had the highest effect on induction of IL-1 by the murine peritoneal macrophages. On the contrary, MDP induced higher IL-1 synthesis by the spleen macrophages. The most active substances with respect to production of TNF, CFs and IL-1, i.e. MDP3 and GMDP4, might be recommended for immunotherapy of syngeneic tumors in animals.
