Solid-phase peptide synthesis (SPPS) has emerged as a cornerstone methodology for the chemical construction of complex peptides, including the intricate lanthipeptide family. These naturally occurring peptides, characterized by their unique lanthionine and methyllanthionine bridges, possess a wide array of biological activities, making their synthesis crucial for research and therapeutic development. SPPS offers a robust and versatile approach to assemble the precise amino acid sequences and facilitate the characteristic cyclizations that define lanthipeptides.
Solid-phase peptide synthesis involves the stepwise addition of amino acids to a growing peptide chain anchored to an insoluble solid support, typically a resin. This method streamlines the synthesis process by allowing for easy removal of excess reagents and byproducts through simple filtration and washing steps after each coupling and deprotection cycle作者：S Mukherjee·2015·被引用次数：1—Solid phase peptide synthesis(SPPS) was used to generate the substrates to study ProcM, and is also a flexibile tool to access non-native .... For lanthipeptides, SPPS is particularly valuable as it enables the controlled introduction of modified amino acids and the strategic formation of the complex thioether cross-links that are essential for their structure and functionFacile Method for Determining Lanthipeptide Stereochemistry.
The synthesis often begins with the attachment of the C-terminal amino acid to the resin. Subsequent cycles involve the deprotection of the N-terminal amino group, followed by the coupling of the next protected amino acid.作者：SM Rowe·2021·被引用次数：38—(5) Lanthionine bridges inlanthipeptidesare typically synthesised using orthogonally protected bisamino acids duringsolid-phase peptide... This iterative process continues until the full linear peptide sequence is assembled. A key challenge in lanthipeptide synthesis is the formation of the lanthionine bridges.To date,solid-phase peptide synthesis(SPPS) is the major chemical strategy forpeptide synthesis(44,–46). It is a stepwise assembly of a peptide chain ... This typically requires the use of specially designed building blocks, such as orthogonally protected bisamino acids, which can undergo cyclization reactions after the linear peptide is synthesized. Strategies often involve late-stage intramolecular cyclization to form these characteristic cross-links, a process that SPPS facilitates by keeping the growing peptide chain tethered to the solid support作者：EL Ongey·2016·被引用次数：138—Industrialpeptideproduction is commonly based on three alternative technologies includingsolid-phase synthesis, liquid-phasesynthesis, and in vivo ....
Several factors are critical for the successful solid-phase peptide synthesis of lanthipeptides. The choice of resin, protecting groups, and coupling reagents must be carefully considered to ensure efficient coupling and to prevent undesirable side reactions. The formation of lanthionine bridges often relies on specific cyclization conditions that need to be compatible with the solid-phase support and other functional groups present in the peptide.
Furthermore, the precursor peptide of lanthipeptides often contains a leader peptide that must be removed during or after synthesis. SPPS can be adapted to incorporate steps for the efficient removal of these leader sequences, either on-resin or after cleavage from the solid support. Researchers often employ Fmoc (9-fluorenylmethyloxycarbonyl) chemistry for SPPS due to its mild deprotection conditions, which are generally well-suited for synthesizing sensitive peptides like lanthipeptides.
While solid-phase peptide synthesis offers precise control over the chemical structure, lanthipeptides are also naturally produced through complex biosynthetic pathways.Solid-Phase Peptide Synthesis Biosynthesis involves ribosomal synthesis of a precursor peptide, followed by extensive post-translational modifications, including dehydration of serine and threonine residues and subsequent cyclization to form lanthionine bridges.Synthesisof the lantibiotic lactocin S usingpeptidecyclizations onsolid phase. · Chemistry.
