CSF114(Glc) is the first synthetic Multiple Sclerosis Antigenic Probe able to identify autoantibodies in a statistically significant number of Multiple Sclerosis patients. The P-turn conformation of this glucopeptide is fundamental for a correct presentation of the epitope Asn(Glc). To verify the influence of sugar mimics in antibody recognition in Multiple Sclerosis, we synthesized Fmoc-protected Asn derivatives containing alkaloid-type sugar mimics. The corresponding glycomimetics-containing peptide derivatives of the CSF114-type sequence were tested in competitive and solid-phase non-competitive ELISA on Multiple Sclerosis patients' sera.
