The chemical synthesis of peptides has revolutionized our ability to produce and study these fundamental biomolecules. Among the various techniques, Solid Phase Peptide Synthesis (SPPS) has emerged as a dominant and highly efficient method for the production of synthetic peptides2023年6月5日—Solid Phase Peptide Synthesis (SPPS) is a method used to create peptides by assembling amino acids in a stepwise fashion on a solid support, .... This approach, pioneered by R. Bruce Merrifield, involves the stepwise assembly of amino acids anchored to an insoluble polymeric resin. This solid support facilitates purification, as excess reagents and byproducts can be easily washed away.

For a complex molecule like Nisin, the synthesis on a solid support requires meticulous planning and execution(PDF) Peptides, solid-phase synthesis and characterization. The process typically begins with the selection of an appropriate solid support and the activation of the first amino acid, which is then coupled to the resin. Subsequent amino acids are added sequentially, each with protected functional groups, to ensure regioselective coupling. Common coupling reagents, crucial for forming the peptide bond, are employed to facilitate this process.

The inherent challenges in the total chemical synthesis of nisin arise from its intricate structure. The presence of modified amino acids, such as those involved in lanthionine ring formation, necessitates specialized synthetic strategies and reagents. Furthermore, the polycyclic nature of Nisin complicates the solid phase peptide synthesis, often requiring intricate cleavage and cyclization steps after the linear peptide is constructed on the resin作者：JC Slootweg·2013—Furthermore, through solution andsolid phase peptide synthesis, mimics ofnisinfragments were successfully prepared replacing the lanthionines .... Researchers have explored various modifications and analogues of Nisin, including replacements for specific amino acids, through SPPS to better understand its structure-activity relationships and to develop novel antimicrobial agents.

The exploration of Nisin synthesis extends beyond producing the native peptide. Semi-synthesis approaches have also been investigated, where parts of the molecule are synthesized chemically, and then combined with naturally derived fragments or modified through enzymatic processes. This can be achieved through solution-phase peptide synthesis or by cleaving the synthesized peptide from the resin and performing further modifications in solution. For instance, researchers have successfully prepared mimics of Nisin fragments by replacing the lanthionines.
