Advancements in Solid-Phase Lantibiotic Synthesis

Solid-phase peptide synthesis (SPPS) has become a cornerstone for producing lantibiotics and their derivatives. This method involves anchoring the growing peptide chain to an insoluble solid support, allowing for efficient washing and purification after each coupling step.Synthesis of Lanthionine-Containing Peptides on Solid Phase ... This is particularly advantageous for assembling the modified amino acids and forming the characteristic thioether bridges found in lantibiotics. Researchers have successfully employed SPPS to synthesize well-known lantibiotics like nisin and lacticin 481, as well as numerous analogues designed to investigate structure-activity relationships or enhance biological properties.

One of the key challenges in lantibiotic synthesis is the incorporation of non-proteinogenic amino acids, such as dehydroalanine (Dha) and lanthionine作者：K Manzor·2017·被引用次数：9—...lantibioticnisin, containing replacements for the Dha at position 5, have been successfully prepared bysolid-phase peptide synthesis.

Solid-phase strategies have been developed to accommodate these building blocks, often utilizing orthogonally protected residues that can be selectively deprotected and coupledSynthesis of the Lantibiotic Lactocin S Using Peptide .... For instance, the synthesis of N-ring analogues of nisin has involved incorporating replacements for the Dha residue using SPPS. Similarly, the synthesis of lactocin S, an antimicrobial peptide produced by *Lactobacillus sakei*, has been achieved through solid-phase peptide cyclizations, demonstrating the method's efficacy for complex lantibiotic structures.

Applications and Future Directions

The ability to synthesize lantibiotics and their analogues via solid-phase methods opens up avenues for exploring their therapeutic potential, particularly in combating antibiotic-resistant bacteria. By creating libraries of lantibiotic variants, researchers can identify compounds with improved potency, broader spectrum activity, or reduced toxicity.
