Optimization of butanediol dimethacrylate crosslinked polystyrene: A novel polymeric support for solid phase peptide synthesis

Studies leading to optimization of butanediol dimethacrylate-crosslinked polystyrene supports (BDDMA-PS) for solid phase peptide synthesis are delineated. BDDMA-PS copolymers with different crosslink densities were prepared and functionalised with chloromethyl groups. The reactivity of the Lys(2-Cl−Z)−OH residue bound to these polymers through a benzyl ester linkage was investigated by following the kinetics of acylation by the HOBt active ester of Boc-Alanine. From the results it was observed that the rate of peptide bond formation was maximum for a 2% BDDMA crosslinked resin. This resin was compared with a 2% DVB-crosslinked polystyrene resin (DVB-PS). Synthesis of an extremely insoluble, hydrophobic, antiparallel β-sheeted difficult sequence peptide LMVGGVVIA (β 34–42), C-terminal fragment of β-amyloid protein, β (1–42), was carried out on both 2% DVB-PS and 2% BDDMA-crosslinked polystyrene supports. The synthesis of the peptide was carried out using Boc amino acid strategy. Greater extent of swelling of the resino peptide, increased coupling efficiency during the assembly of amino acids and relatively high purity of synthesised peptide were observed in the case of 2% BDDMA-PS polymer.
