Lanthipeptides are a unique class of post-translationally modified peptides characterized by the presence of lanthionine (Lan) and methyllanthionine (MeLan) residues. These thioether-bridged macrocycles are fascinating from a structural perspective. They contain lanthionine (Lan) and methyllanthionine (MeLan) residues, which pose unique challenges during chemical assembly. Whether one is working on total synthesis of several lanthipeptides or specific analogues, the structural integrity of these bridges is paramount.

It is widely recognized in the scientific community that Fmoc SPPS is the method of choice for peptide synthesis. This preference stems from the mild deprotection conditions and the availability of high-quality building blocks. When discussing lanthipeptide Fmoc-SPPS total synthesis, we are essentially looking at a refined workflow that balances efficiency with the delicacy of the thioether linkages.
In my experience with solid-phase peptide synthesis, the choice of resin and the precision of the SPPS procedure are critical.

While synthetic oligonucleotides often show lower mass intensity, the Fmoc Solid-Phase Peptide Synthesis total synthesis of peptides via SPPS remains a robust, albeit resource-intensive, approach.
Key Considerations for Modern Synthesis
For those looking to replicate or innovate within this space, consider these essential factors:
* Methodology: The integration of Fmoc chemistry allows for the orthogonal protection of residues, which is crucial when dealing with sensitive lanthionine bridges.
* Sustainability: Current trends focus on reducing solvent waste during solid-phase peptide synthesis, making the process more environmentally conscious.
* Complexity: Whether you are working with a full-length sequence or a shorter peptide fragment, the synthesis must account for the specific macrocyclization strategy employed.
