Recently, our group report a novel approach to a totally synthetic vaccine which consists of FMDV (Foot and Mouth Disease Virus) VP1 peptides, prepared by covalent conjugation of peptide biomolecules with membrane active carbochain polyelectrolytes In the present study, peptide epitops of VP1 protein both 135-161(P1) amino acid residues (Ser-Lys-Tyr-Ser-Thr-Thr-Gly-Glu-Arg-Thr-Arg-Thr-Arg-Gly-Asp-Leu-Gly-Ala-Leu-Ala-Ala-Arg-Val-Ala-Thr-Gln-Leu-Pro-Ala) and triptophan (Trp) containing on the N terminus 135-161 amino acid residues (Trp-135-161) (P2) were synthesized by using the microwave assisted solid-phase methods. Using as a template a peptide, already identifi ed, with agonist activity against PTPRJ(H-[Cys-His-His-Asn-Leu-Thr-His-Ala-Cys]-OH), here we report a structure-activity study carried out through endocyclic modifi cations (Ala-scan, D-substitutions, single residue deletions, substitutions of the disulfi de bridge) and the preliminary biological results of this set of compounds.	./cache/cord-023209-un2ysc2v.txt	./txt/cord-023209-un2ysc2v.txt
