The lipophilic tail was then. Nisin, a well-known bacteriocin belonging to the lantibiotic class, has garnered significant attention due to its potent antimicrobial activity. To explore its structure-activity relationships and develop novel therapeutic agents, researchers have increasingly turned to solid-phase peptide synthesis (SPPS)作者：K Manzor·2017·被引用次数：8—A number of A-ring analogues of the lantibioticnisin, containing replacements for the Dha at position 5, have been successfully prepared bysolid-phase.... This article delves into the intricacies of nisin chemical synthesis utilizing solid phase peptide synthesis methodologies, highlighting its importance in creating functional peptides and analogues.

Solid-phase peptide synthesis (SPPS) has revolutionized peptide chemistry by enabling the stepwise assembly of amino acids on an insoluble polymer support, commonly referred to as a resin. This approach offers significant advantages over traditional solution-phase methods, including simplified purification, automation capabilities, and the ability to synthesize longer and more complex peptides(PDF) Synthesis of the Lantibiotic Lactocin S Using Peptide .... The solid phase nature of the synthesis allows for efficient washing steps to remove excess reagents and byproducts, ensuring a high purity of the final product. Various resins, such as Wang resin or Rink amide resin, are employed depending on the desired C-terminus of the peptide.

The chemical synthesis of nisin and its analogues presents unique challenges due to the presence of modified amino acids, including thioether linkages and dehydroamino acids like dehydroalanine (Dha). Researchers have successfully adapted SPPS techniques to incorporate these modifications.Synthesis and Conformational Studies of the Lipid II- ... For instance, the synthesis of nisin A-ring analogues has involved replacing the Dha at position 5, demonstrating the flexibility of solid phase peptide synthesis in generating structural variations. Furthermore, the creation of lipidated variants of the antimicrobial peptide nisin often requires specific chemical synthesis strategies to attach lipid moieties to the peptide backbone, typically at the C-terminus.

The development of nisin analogues through solid-phase peptide synthesis is not merely an academic exercise; it holds immense potential for drug discovery and development. By systematically altering the amino acid sequence or incorporating non-natural modifications, researchers can fine-tune the antimicrobial spectrum, enhance stability, or improve pharmacokinetic properties. This exploration of peptide chemistry is vital for designing next-generation antimicrobials to combat the growing threat of antibiotic resistance.

Beyond nisin, the solid phase peptide synthesis methodology is broadly applicable to the chemical synthesis of other lantibiotics and ribosomally synthesized and post-translationally modified peptides (RiPPs). The successful construction of peptides like lactocin S and lacticin 3147 using SPPS underscores its power in accessing these complex natural products. The ability to perform chemical synthesis on a solid phase allows for the creation of specific ring structures, such as A and B rings of nisin, enabling detailed studies of their molecular recognition properties, particularly their interaction with Lipid II, a key component of bacterial cell membranes.

In conclusion, the chemical synthesis of nisin and its analogues via solid-phase peptide synthesis is a cornerstone of modern antimicrobial research.
