Furthermore, side reactions are a significant concern during the synthesis process. The complex microenvironment on the surface of the solid support can inadvertently trigger unwanted chemical transformations.作者：C Petrou·2018·被引用次数：62—This chapter provides an overview ofpeptide synthesisgiving emphasis onsolid-phase peptide synthesis(SPPS). These can include racemization, where the stereochemical integrity of amino acids is compromised, and incomplete coupling reactions leading to deletion sequences. Incomplete coupling reactions and racemisation are particularly problematic as they directly impact the purity and biological activity of the final peptide product. The reliance on specific coupling reagents designed to facilitate amide bond formation can sometimes lead to these undesirable outcomes, especially with sterically hindered amino acids or those with complex side chains作者：C Petrou·2018·被引用次数：62—This chapter provides an overview ofpeptide synthesisgiving emphasis onsolid-phase peptide synthesis(SPPS)..

The time-consuming purification steps are another notable drawback of SPPS.Automated solid-phase peptide synthesis to obtain ... While the solid-phase approach simplifies the removal of excess reagents and by-products after each coupling and deprotection step, the final cleavage of the peptide from the resin and subsequent purification can still be labor-intensive2025年1月7日—While SPPS is highly effective, challenges remain, includingincomplete coupling reactions and racemisation. Advances in coupling reagents, .... This is particularly true when dealing with peptides that have undergone numerous cycles of synthesis. The efficiencies of solid-phase synthesis are lost in the solution phase steps once the peptide is cleaved from the resin, necessitating traditional purification techniques like chromatography.Common Side Reactions in Fmoc Solid-Phase Peptide ...

A significant limitation of SPPS is its challenges with longer peptides.作者：M NUÑO·2020—Two of the major challenges on solid-phase peptide synthesis are thedifficulties in monitoring reactions in real timeand the need to accommodate volume ... As the peptide chain grows, the cumulative effect of incomplete reactions can lead to a significant proportion of truncated or deletion sequences.Resins for Solid Phase Peptide Synthesis The ease of assembly of a given peptide sequence is hard to predict, making it difficult to anticipate which sequences might prove more challenging to synthesize efficientlyResins for Solid Phase Peptide Synthesis. Consequently, SPPS is limited by yields, and typically peptides and proteins in the range of 70 amino acids are pushing the limits of synthetic accessibility.Solid vs Liquid Phase Peptide Synthesis This means that for very long peptides, alternative or hybrid synthesis strategies might be more effectiveSolid Phase Peptide Synthesis Process and Applications ....

The environmental impact and cost associated with SPPS are also considerable disadvantages. The method often requires large volumes of organic solvents for coupling, deprotection, and washing steps.
