Silica-Assisted Solid-Phase Peptide Synthesis (SiPPS)
Plain-language summary
Paraphrased from the published abstract below — not a verdict on whether anything works.
This study (not involving a biological species) developed a non-swelling silica-based resin method for peptide synthesis, termed silica-assisted solid-phase peptide synthesis (SiPPS), using a strategy similar to standard solid-phase peptide synthesis (SPPS). A 2-h coupling time appeared to favor coupling compared with a 1-h standard coupling, and the non-swelling resin allowed a 50% reduction in solvent consumption. The approach was demonstrated for synthesis of H-YSSFL-NH2, linear oxytocin, angiotensin II, and afamelanotide using a silica-based Fmoc-Rink amide SiliaBond support, with the resulting peptides reported to have more than acceptable purity, though with some loss in overall yield.
Abstract
Non-swelling silica-based resin was used for peptide synthesis. The strategy used is similar to that of solid-phase peptide synthesis (SPPS), referred to as silica-assisted solid-phase peptide synthesis (SiPPS). A 2-h coupling seemed to favor the coupling compared to that of 1-h standard coupling. The use of this non-swelling resin allows a 50% reduction in the consumption of solvents. The strategy was well demonstrated for the synthesis of H-YSSFL-NH2, linear oxytocin, angiotensin II, and afamelanotide using a silica-based support (Fmoc-Rink amide SiliaBond manufactured from SiliCycle Inc.). The peptides were found to have more than acceptable purity, although there was a loss in overall yields.
