The Principles of Solid-Phase Peptide Synthesis

Solid-phase peptide synthesis, pioneered by R作者:I Coin·2007·被引用次数:885—This protocol forsolid-phase peptide synthesis(SPPS) is based on the widely used Fmoc/tBu strategy, activation of the carboxyl.. Bruce Merrifield, revolutionized the way peptides are made.作者:M Stawikowski·2002·被引用次数:328—This unit provides an overview of the field of syntheticpeptidesand proteins. It discusses selecting thesolidsupport and common coupling reagents. The fundamental principle involves anchoring the first amino acid to an insoluble polymer resin. Subsequent amino acids are then sequentially added and coupled to the growing peptide chain, which remains covalently attached to the solid support throughout the process. This attachment to a solid phase simplifies the purification steps, as excess reagents and byproducts can be easily washed away after each coupling reaction.

The process typically involves several key steps for each amino acid addition:

* Deprotection: The N-terminal protecting group of the last added amino acid is removed to expose a reactive amino group.

* Activation and Coupling: The next amino acid, with its C-terminus activated, is coupled to the deprotected amino group of the growing peptide chain.

* Washing: The resin is washed extensively to remove unreacted reagents and byproductsSolid phase protein chemical synthesis.

This cycle is repeated until the desired peptide sequence is assembledA Practical Guide to Solid Phase Peptide Synthesis (SPPS). Finally, the completed peptide is cleaved from the resin, and any side-chain protecting groups are removed.We present a process forsolid phase peptide synthesis(SPPS) that completely eliminates all solvent intensive washing steps during each amino acid addition ...

Advantages and Variations of SPPS

The primary advantage of SPPS lies in its efficiency and relative simplicity compared to traditional solution-phase synthesis. The ability to wash away excess reagents and byproducts without complex purification steps significantly speeds up the synthesis process and increases the overall yield of the target peptide. Furthermore, SPPS is amenable to automation, allowing for high-throughput synthesis of multiple peptides simultaneouslySynthesis Notes.

Several variations and refinements of the original SPPS method have been developed to enhance efficiency and address specific challenges:

* Fmoc/tBu Strategy: This widely used strategy employs the base-labile fluorenylmethyloxycarbonyl (Fmoc) group for N-terminal protection and acid-labile tert-butyl (tBu) based groups for side-chain protection. It is favored for its compatibility with mild cleavage conditions and its suitability for synthesizing sensitive peptides.

* Boc/Bzl Strategy: An older but still relevant strategy utilizes the acid-labile tert-butyloxycarbonyl (Boc) group for N-terminal protection and benzyl (Bzl) based groups for side-chain protectionLanthipeptides: chemical synthesis versus in vivo biosynthesis .... This method typically requires strong acidic conditions for cleavage.

* Microwave-Assisted SPPS: Incorporating microwave irradiation can significantly reduce reaction times for coupling and deprotection steps, leading to faster and more efficient peptide synthesis.Insolid-phase peptide synthesis(SPPS), the growing peptide chain is anchored at its C-terminus to an insoluble polymer.

* Continuous Flow SPPS: Advancements in technology have led to the development of continuous flow systems that offer improved control over reaction parameters, enhanced scalability, and potentially reduced solvent consumption. Some innovative approaches aim to completely eliminate washing steps, further streamlining the process.
