A study detailing the synthesis of a glycotripeptide and a glycosomatostatin, both containing the 3-O-(2-acetamido-2-deoxy-D-glucopyranosyl)-L-serine residue. The research was conducted by a team from the Salk Institute for Biological Studies and the University of California, San Diego. The process involved solid-phase synthesis to create the sequences Gly-[P-D-GlcpNAc-(1→3)-Ser]-Ala-OH and /I-D-GlcpNAc-(1→3)-Ser-13-somatostatin. The synthesized glycopeptides were found to be homogeneous upon examination through thin-layer chromatography (t.l.c.) and liquid chromatography (l.c.), and they exhibited the correct amino acid composition and 2-amino-2-deoxy-D-glucose content. The structure of one of the glycopeptides was confirmed by mass spectrometry and nuclear magnetic resonance (n.m.r.) spectroscopy. The study was supported by grants from the National Institute of Arthritis, Metabolism, and Digestive Diseases, the National Heart Institute, and the William Randolph Hearst Foundation, among others.
