  Synthesis and Biological Evaluation of New Mannose Derived Immunomodulating Adamantyltripeptides

  摘要：

  A novel class of mannosylated adamantyltripeptides, general formula of which is alpha-Man-OCH2CH(CH3)CO-AdGly-L-Ala-D-isoGln, were prepared, characterized, and their possible immunomodulatory properties investigated in some preliminary tests in vivo. All newly synthesized glycopeptides comprise in their structure the adamantylglycyl moiety linked to the dipeptide L-Ala-D-isoGln, as well as mannose. Adjuvant activity of mannosylated adamant-2-yl tripeptides was tested in the mouse model using ovalbumin as an antigen and in comparison to the peptidoglycan monomer (PGM, beta-D-GlcNAc-(1 -> 4)-D-MurNAc-L-Ala-D-isoGln-mesoDAP(epsilon NH2)-D-Ala-D-Ala).
