Synthesis of ethoxy-linked pseudo-disaccharides incorporating a crown ether macrocycle and lectin recognition
摘要:
Six ethoxy-linked pseudo-disaccharides incorporating a non-reducing D-galactopyranosyl residue and a glucose bearing an 18-crown-6-ether were synthesized by the trichloracetimidate method. Deprotection left four novel structures from which two were tested against the galactose-specific lectin Kluyveromyces bulgaricus. Their minimum inhibitory concentration (MIC) was in the same order of magnitude as compared to previously prepared oligosaccharides without spacer. (C) 1999 Elsevier Science Ltd. All rights reserved.
