This review delves into the fundamental principles, advancements, and practical considerations of solid-phase peptide synthesis, offering a detailed overview for researchers and practitioners. The development of SPPS, pioneered by R.Liquid Phase vs. Solid Phase Peptide Synthesis: Pros and ConsB. Merrifield in the 1960s, revolutionized peptide synthesis, earning him the Nobel Prize in Chemistry in 1984.作者：L Raibaut·2015·被引用次数：77—This review details pioneering studies and the most recent publications related to thesolid phase chemical synthesis of large peptides and proteins. This method offers a distinct advantage over traditional solution-phase peptide synthesis due to its efficiency and ease of automation.

The core principle of solid-phase synthesis involves anchoring the first amino acid to an insoluble polymer support, known as a resin. Subsequent amino acids are then sequentially added and coupled to the growing peptide chain, which remains attached to the solid support throughout the entire synthesis process.Introduction to Peptide Synthesis This approach allows for the removal of excess reagents and byproducts through simple filtration and washing steps, significantly simplifying purification compared to liquid phase peptide synthesis. The ease of assembly of a given peptide sequence can be challenging to predict, which makes peptide synthesis a complex endeavor, but SPPS has significantly streamlined the processSolid phase peptide synthesis review.

Key Methodologies and Advancements in SPPS

Two primary methodologies dominate Fmoc solid-phase peptide synthesis: the Fmoc/tBu strategy and the Boc/Bzl strategy作者：JM Collins·2023·被引用次数：52—We present a process forsolid phase peptide synthesis(SPPS) that completely eliminates all solvent intensive washing steps during each .... The Fmoc SPPS approach, which utilizes the base-labile 9-fluorenylmethyloxycarbonyl (Fmoc) group for $\alpha$-amino protection and acid-labile tert-butyl (tBu) based side-chain protecting groups, has become the method of choice for many applications. As highlighted in numerous reviews, Fmoc SPPS was easy to automate due to the avoidance of corrosive reagents like trifluoroacetic acid (TFA) during the synthetic cycles, with deprotection releasing a fluorene byproduct.

* Cleavage and Deprotection: Once the full peptide sequence is assembled, the peptide is cleaved from the resin, and all side-chain protecting groups are removed simultaneously, typically using a strong acid cocktail.

Recent innovations aim to improve the sustainability of SPPS. For instance, research into total wash elimination for solid phase peptide synthesis seeks to reduce solvent consumption, a significant environmental concern in large-scale synthesis. Furthermore, the development of handles for solid-phase peptide synthesis that are highly acid labile, often based on benzylic C-N bond cleavage, offers more precise control over the cleavage process.
