The advantage of SPPS lies in its ability to simplify purification by allowing excess reagents and byproducts to be washed away after each coupling step, making it more efficient than traditional solution-phase methods which are often arduous and laborious, requiring extensive purification like recrystallization or column chromatography. For lanthipeptides, SPPS provides a flexible platform for building the peptide backbone and introducing the necessary modified amino acids or precursors for the formation of lanthionine bridges.an analogue of rings D and E of the lantibiotic nisin. - Abstract

Strategies for Lanthipeptide Synthesis

The total synthesis of lanthipeptides presents significant challenges due to the unique post-translational modifications requiredCell-free biosynthesis and engineering of ribosomally .... One common approach involves the synthesis of precursor peptides containing cysteine residues, which are then cyclized to form the characteristic lanthionine bridges. Strategies often employ orthogonally protected amino acids, particularly bisamino acids, during the solid-phase synthesis to facilitate the formation of these bridges. Some methods focus on desulfurization approaches to generate lanthionine structures, while others involve the synthesis of sulfamidate-containing peptides followed by late-stage intramolecular cyclization. The ability to perform solid-phase synthesis of overlapping lanthionine bridges has also been a key development in the field, enabling the construction of complex lantibiotic structures.
