Solid phase peptide synthesisMerrifield Solid phase peptide synthesis (SPPS) stands as a cornerstone in the production of peptides, organic molecules composed of amino acids linked by peptide bonds. Since its pioneering development by Robert Bruce Merrifield, this technique has revolutionized the field, offering a more efficient and manageable alternative to traditional solution phase peptide synthesis. Unlike its predecessor, which is typically arduous and laborious, SPPS involves synthesizing the growing peptide chain while it remains attached to an insoluble solid support, most commonly small, polymeric resin beads functionalized with reactive groups like amine or hydroxyl groups作者：MJ O'Donnell·1996·被引用次数：166—Solid-phase peptide synthesis (SPPS) has evolved into a powerful synthetic method since it was first reported in 1963.1,2It is considered the method of .... This strategic tethering simplifies purification and facilitates automation, making it a preferred method for both research and industrial applications.What is solid phase peptide synthesis?

The fundamental principle of solid phase synthesis involves the step-wise construction of a polypeptide chain. The process begins by attaching the C-terminal amino acid, which is first protected with a temporary group, to the solid phase material or resinUltra-Efficient Solid Phase Peptide Synthesis (UE-SPPS). Subsequently, amino acids are added sequentially, one by one, to the growing chain. Each addition involves several key steps: deprotection of the N-terminus of the immobilized amino acid, activation of the carboxyl group of the next incoming amino acid, and finally, the coupling of this activated amino acid to the deprotected N-terminus.Solid Phase Peptide Synthesis (SPPS) explained - Bachem After each coupling step, excess reagents and by-products are washed away, leaving the growing peptide chain firmly anchored to the resin.作者：F Guzmán·2023·被引用次数：36—Solid-Phase Peptide Synthesis (SPPS) is a mature technique widely used in research and in production.

Two primary methodologies dominate solid phase peptide synthesis: Fmoc (9-fluorenylmethyloxycarbonyl) and Boc (tert-butyloxycarbonyl) chemistry. The Fmoc Solid Phase Peptide Synthesis (Fmoc-SPPS) method is widely adopted due to its mild deprotection conditions.Solid phase peptide synthesis | PPT In Fmoc-SPPS, the Fmoc group, a base-labile protecting group, is removed using a weak base, typically piperidine, allowing for the coupling of the next amino acid without damaging the growing peptide chain or the resinsolid phase peptide synthesis. This strategy is often combined with solid phase FMOC or BOC chemistry methodologies, utilizing acid-labile side-chain protecting groups. Alternatively, the Boc strategy employs an acid-labile Boc group for temporary N-terminal protection and stronger acids for its removal.Overview of Solid Phase Peptide Synthesis (SPPS) The choice between Fmoc and Boc largely depends on the specific peptide sequence and the desired overall strategy.
