Specific crosslinking of cell adhesive molecules by heterobifunctional glycopeptide synthesised on the basis of chemoenzymatic strategy
Abstract
Heterobifunctional glycopeptide 1 composed of Neu5Acα-(2→3)Galβ(1→4)[Fucα(1→3)]GlcNAc (sialyl Lewisx) and Lys-Gly-Arg-Gly-Asp-Ser (KGRGDS) having specific activity to bind concurrently with two different types of cell adhesive molecules such as selectins and integrins was synthesised on the basis of a combined chemical and enzymatic strategy.
