When referring to the total synthesis of peptides, especially those with significant therapeutic or biological relevance, SPPS is often the method of choice for constructing the primary amino acid backbonesolid phase peptide. However, complex peptides may feature non-proteinogenic amino acids, post-translational modifications, or unique structural elements that require specialized synthetic approaches. For instance, the synthesis of lanthionine peptides or antimicrobial peptides might involve incorporating modified amino acids or cyclization steps. The ability to perform SPPS on a larger scale also allows for the production of peptides in quantities sufficient for detailed biochemical and pharmacological studies. Researchers often leverage SPPS for the total synthesis of antibiotic peptides, leveraging its efficiency for creating diverse peptide sequences.
Despite its power, SPPS is not without its challenges. Incomplete coupling or deprotection reactions can lead to deletion sequences, where an amino acid is missingRecent Progress in Solid‐Phase Total Synthesis of Naturally .... Side reactions, such as racemization or epimerization, can occur during the coupling step, potentially altering the chirality of amino acids and thus the biological activity of the final peptide. The development of highly efficient coupling reagents and optimized protocols has been crucial in minimizing these issues. Furthermore, the cleavage of the peptide from the resin and the removal of side-chain protecting groups require careful selection of reagents to avoid peptide degradation. Monitoring the progress of the synthesis, for example, through spectrophotometric detection of residual piperidine in Fmoc-SPPS, is vital for ensuring reaction completion and optimizing protocols.作者：S Chattopadhyay·2022·被引用次数：16—Accordingly, we synthesized the 33-mer peptide Tβrl–CMP and its Tβrl and CMP components bysolid-phase peptide synthesis(SPPS).

The efficiency of SPPS can also be impacted by the length and sequence of the peptide. Longer peptides are more prone to aggregation on the resin, which can hinder reagent access and reduce coupling efficiency.Biosynthesis of the Antimicrobial Peptide Epilancin 15X ... Strategies such as using modified resins, optimizing solvent systems, or employing convergent synthesis approaches (assembling smaller peptide fragments before final ligation) are employed to overcome these limitations.Synthesis Notes Innovations like "total wash elimination" in SPPS aim to reduce solvent usage and streamline the process, making it more environmentally friendly and cost-effective.
