Solid phase synthesis Solid phase peptide synthesis (SPPS) stands as a cornerstone technique in the creation of peptides, offering a robust and efficient alternative to traditional solution-phase methods. This method, pioneered by Robert Bruce Merrifield, who was awarded the Nobel Prize in Chemistry for his groundbreaking work, involves the step-wise construction of a polypeptide chain while it remains attached to an insoluble solid support, typically small, polymeric resin beads. The inherent advantages of SPPS, such as higher yields and simplified purification, have made it the method of choice for both academic research and large-scale production.The established method for the production of synthetic peptides is known assolid phase peptide synthesis(SPPS).

The fundamental principle of solid phase peptide synthesis lies in anchoring the first amino acid, specifically the C-terminal residue, to a solid phase material or resin.The Auer Lab - Solid Phase Peptide Synthesis (SPPS) This initial attachment is crucial, as the growing peptide chain will remain covalently bonded to this inert solid throughout the synthesis process. This contrasts sharply with solution phase peptide synthesis, which is often arduous and laborious, demanding lengthy coupling reaction times and requiring extensive purification steps like recrystallization or column chromatography after each amino acid addition作者：M Stawikowski·2002·被引用次数：327—Solid phase peptide synthesis is traditionally carried out in the C → N direction.

The SPPS Workflow: A Step-by-Step Assembly

The process of solid phase peptide synthesis is traditionally carried out in the C → N direction. This means that amino acids are added sequentially to the C-terminus of the growing peptide chain. The majority of peptides synthesized using this method are produced as C-terminal acids or amides.

The core steps involved in SPPS include:

1. Resin Attachment: The first amino acid, with its amino group protected, is covalently linked to the solid support resin. Common resins include polystyrene beads, often functionalized with reactive groups such as amine or hydroxyl groups. Solid phase peptide synthesis resin selection is critical for successful synthesis.作者：M Stawikowski·2002·被引用次数：327—Solid phase peptide synthesis is traditionally carried out in the C → N direction.

Coupling: The next amino acid, also with its amino group protected and its carboxyl group activated, is added to the reaction mixture. This activated amino acid then forms a peptide bond with the free amine on the growing peptide chain. Various activation strategies are employed, with the Fmoc/tBu strategy being a widely used and effective approach. This strategy involves activation of the carboxyl groups by aminium-derived reagentsIntroduction to Peptide Synthesis - PMC - NIH.
