Synthesis and structure of a bis-glycosylated hexa-β-peptide
摘要:
The bis-glycosylated hexapeptide beta-Ala-beta-Ala-(beta-D-Glc)-L-Asp-beta-Ala-beta-Ala-(beta-D-Gal)-L-Asp (14) is prepared by fragment condensation of Fmoc-beta-Ala-beta-Ala-(beta-D-GlcAc(4))-L-Asp-OH (11) and H2N-beta-Ala-beta-Ala-(beta-D-GalAc(4))-L-Asp-(OBu)-Bu-t (12) under optimized conditions with the HBTU/HOBt reagent followed by deprotection of the intermediate fully protected hexapeptide. Hexapeptide 14 is shown to adopt a random coil structure in solution.
