Bruce Merrifield in the 1960s, a feat for which he was awarded the Nobel Prize in Chemistry, SPPS has evolved into a mature and widely adopted method for both research and industrial production. This article delves into the intricacies of solid-phase peptide synthesis, exploring its fundamental principles, advantages, and the essential components that contribute to its success.

At its core, Solid Phase Peptide Synthesis (SPPS) is a method used to create peptides by assembling amino acids in a stepwise fashion on a solid support, typically a resinSolid-phase Peptide Synthesis (SPPS) in Research & .... This ingenious approach allows for the efficient synthesis of peptide chains, which are organic molecules consisting of between 2 and 50 amino acids linked by peptide (amide) bonds作者：KE Ruhl·2024·被引用次数：19—We describe a continuous-flow (CF) SPPS workflow tooptimize and deliver multigram quantities of peptide fragments, which are easily transformed to macrocyclic .... Unlike traditional solution-phase synthesis, which can be arduous and laborious, requiring extensive purification steps like recrystallization or column chromatography after each coupling, SPPS simplifies the process significantly.

The general process of synthesizing peptides on a resin begins with the attachment of the first amino acid, known as the C-terminal residue, to an insoluble polymeric solid support. This solid support material acts as an anchor, allowing the growing peptide chain to be held throughout the synthesis. Subsequently, amino acids are added sequentially, one by one, to the N-terminus of the growing chain. Each addition involves a coupling reaction, where the activated carboxyl group of the incoming amino acid reacts with the free amine group of the immobilized peptide作者：I Coin·2007·被引用次数：881—This protocol forsolid-phase peptide synthesis (SPPS) is based on the widely used Fmoc/tBu strategy, activation of the carboxyl groups by aminium-derived .... Before the next amino acid can be added, the temporary protecting group on the amine of the last added amino acid must be removed. This deprotection step is crucial for exposing the amine group for the next coupling reaction.

One of the most widely used strategies in solid-phase peptide synthesis is the Fmoc/tBu strategy.Overview of Solid Phase Peptide Synthesis (SPPS) In this approach, the alpha-amino group of each incoming amino acid is protected by a Fmoc (9-fluorenylmethyloxycarbonyl) group, which is labile to a mild base like piperidine. The side chains of the amino acids are typically protected by acid-labile groups, such as tert-butyl (tBu) derivatives作者：I Coin·2007·被引用次数：881—This protocol forsolid-phase peptide synthesis (SPPS) is based on the widely used Fmoc/tBu strategy, activation of the carboxyl groups by aminium-derived .... This orthogonality ensures that the Fmoc group can be selectively removed without affecting the side-chain protecting groups or the linkage to the resin.作者：KE Ruhl·2024·被引用次数：19—We describe a continuous-flow (CF) SPPS workflow tooptimize and deliver multigram quantities of peptide fragments, which are easily transformed to macrocyclic ... Following the completion of the peptide chain assembly, a strong acid, such as trifluoroacetic acid (TFA), is used to cleave the peptide from the resin and simultaneously remove all side-chain protecting groupsSolid Phase Peptide Synthesis (SPPS) was introduced in the 1960s by Robert Bruce Merrifield1, to whom was later awarded to Nobel Prize in Chemistry for ....

The advantages of solid-phase peptide synthesis over its liquid-phase counterpart are numerous. The solid support facilitates the removal of excess reagents and byproducts through simple washing steps, eliminating the need for intermediate purification. This significantly speeds up the synthesis and allows for a higher overall yield.作者：M Stawikowski·2002·被引用次数：327—... solid-phase techniques.

Furthermore, the ability to automate the process has led to the development of Automated solid-phase peptide synthesis (SPPS), which offers a suitable technology to produce chemically engineered peptides efficiently and reproducibly. This automation streamlines the successive addition of protected amino acid derivatives, leading to greater consistency and reduced manual laborPeptides, solid-phase synthesis and characterization.

While traditional SPPS involves resin washing steps after each coupling and deprotection, advanced methodologies have emerged to further enhance efficiencyGuide to Solid Phase Peptide Synthesis - AAPPTEC. Ultra-Efficient Solid Phase Peptide Synthesis (UE-SPPS), for instance, is a revolutionary approach that completely eliminates these washing steps, further optimizing the peptide production workflow. Continuous-flow SPPS is another innovative development, enabling the optimization and delivery of multigram quantities of peptide fragments, which can then be easily transformed into more complex structures like macrocyclic peptides.
