Solid phasepeptide synthesisprotocol The field of biochemistry and organic chemistry was profoundly transformed in the late 1950s and early 1960s by the pioneering work of R. Bruce Merrifield. 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作者：NE Robinson·2008·被引用次数：29—Merrifield peptide synthesishas been used to synthesize the ∼1000 peptides for experiments to determine the primary sequence dependence of .... 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作者：C Birr·被引用次数：3—Already in the incipience period ofMerrifield'smethod it was demonstrated that the new idea included the possibility for automatization of most of the ....

At its core, Merrifield peptide synthesis is characterized by the peptide being 'immobilised' onto the solid-phase.作者：AR Mitchell·2008·被引用次数：98—Bruce Merrifield, trained as a biochemist, had to address three major challenges related to the development and acceptance ofsolid-phase peptide synthesis( ... 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. This contrasts with traditional liquid-phase synthesis, where isolating and purifying intermediates can be a labor-intensive and often inefficient processBruce Merrifield and solid-phase peptide synthesis. 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. A new, protected amino acid is then activated and coupled to the free amino group of the growing peptide chainBruce Merrifield and solid‐phase peptide synthesis: A .... This cycle is repeated for each subsequent amino acid, building the peptide chain step-by-step作者：NE Robinson·2008·被引用次数：29—Merrifield peptide synthesishas been used to synthesize the ∼1000 peptides for experiments to determine the primary sequence dependence of .... 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.2014年2月2日—Solid phase peptide synthesis (SPPS), developed by RB Merrifield, was a major breakthrough allowing for the chemical synthesis of peptides and small proteins. The repetitive nature of the deprotection and coupling steps, coupled with the ease of washing the resin-bound peptide, makes it an ideal candidate for automated synthesizers (solid-phase peptide synthesis equipment).Use of Merrifield solid phase peptide synthesis in ... This automation, explored as early as the incipient period of Merrifield's method by researchers like C. Birr, significantly increased the speed and efficiency of peptide synthesis. This has led to advancements such as Merrifield Synthesis 2.Merrifield Solid-Phase Peptide Synthesis0, which aims for even greater efficiency in both time and product purity, often eliminating the need for certain challenging manual steps and resulting in more sustainable synthesis.
