His development of solid-phase peptide synthesis (SPPS), often referred to as the Merrifield method, marked a significant breakthrough, enabling the chemical synthesis of peptides and even subsequent synthesis of peptides of up to 50 amino acids. This innovative approach, which earned Merrifield the Nobel Prize in Chemistry in 1984, fundamentally altered how scientists could create and study these crucial biological molecules.

At its core, Merrifield peptide synthesis is characterized by the peptide being 'immobilised' onto the solid-phase. This means that the growing amino acid chain is covalently bonded to small beads of a polymeric resin, most famously Merrifield's peptide resin. This solid support serves as an anchor, allowing for efficient purification by simply filtering away excess reagents and by-products after each reaction step.2024年9月30日—In theMerrifieldsolid-phase method,peptide synthesisis carried out with the growing amino acid chain covalently bonded to small beads of a polymer resin. This contrasts with traditional liquid-phase synthesis, where isolating and purifying intermediates can be a labor-intensive and often inefficient process. The Merrifield resin typically utilizes a chloromethylated polystyrene backbone, with the first amino acid's C-terminus attached to the resin via an SN2 reaction, initiating the chain elongation.

The Merrifield Synthesis mechanism involves a cyclical process of deprotection and coupling. After the initial attachment of the C-terminal amino acid, its $\alpha$-amino group is deprotected.作者：NE Robinson·2008·被引用次数：29—Merrifield solid phase peptide synthesishas been the principle research procedure used in the study of the chemistry and biological use of deamidation. A new, protected amino acid is then activated and coupled to the free amino group of the growing peptide chain. This cycle is repeated for each subsequent amino acid, building the peptide chain step-by-step. The amino acid protection is crucial; side chains of amino acids are protected with specific chemical groups to prevent unwanted reactions during the synthesis. Common protection strategies include Boc (tert-butyloxycarbonyl) and Fmoc (fluorenylmethyloxycarbonyl) chemistries, depending on the specific protocol and desired outcome. For instance, Boc solid-phase peptide synthesis was an early and widely adopted approach.

One of the most significant advantages of solid-phase peptide synthesis is its amenability to automation.作者：RB Merrifield·1965·被引用次数：856—Automated Synthesis of Peptides:Solid-phase peptide synthesis, a simple and rapid synthetic method, has now been automated.
