Efficient methodology for the cyclization of linear peptide libraries via intramolecular S-alkylation using Multipin solid phase peptide synthesis.
Methodology is described here for the efficient parallel synthesis and cyclization of linear peptide libraries using intramolecular S-alkylation chemistry in combination with Multipin solid phase peptide synthesis (Multipin SPPS). The effective use of this methodology was demonstrated with the synthesis of a 72-member combinatorial library of cyclic thioether peptide derivatives of the conserved four-residue structural motif DD/EXK found in the active sites of the five crystallographically defined orthodox type II restriction endonucleases, EcoRV, EcoRI, PvuII, BamHI and BglI.
