Novel mannosyl derivatives of peptidoglycan monomer: Synthesis and biological evaluation of immunomodulatory properties
摘要:
The aim of this work was to prepare mannosyl derivatives of peptidoglycan monomer (PGM, beta-D-GlcNAc( 1 -> 4)-D-MurNAc-L-Ala-D-isoGln-mesoDAP(epsilon NH(2))-D-Ala-D-Ala) in order to study the effects of mannosylation on adjuvant (immunostimulating) activity. Novel Man-OCH(2)CH(CH(3))CO-PGM isomers were substrates for N-acetylmuramyl-L-alanine amidase, like the parent PGM molecule. Adjuvant activity of Man-OCH(2)CH(CH(3)) CO-PGM was tested in the mouse model using ovalbumin as an antigen. (C) 2009 Elsevier Ltd. All rights reserved.
