Lanthipeptides are, by definition, ribosomally synthesized and post-translationally modified peptides (RiPPs). Their structural hallmark—the thioether crosslink—makes Ring-opening reactions for the solid-phase synthesis of them incredibly stable and biologically fascinating. In my experience, understanding how these molecules are constructed is vital. Historically, lanthipeptides are synthesized from a genetically encoded precursor peptide, LanA, which includes a leader sequence that guides t by AH Garcia · 2023 · Cited by 15 — Here, we reconstitute the biosynthetic pathway for a class III lanthipeptide from Bacillus thuringiensis NRRL B-23139, including characterization of a two- he modification process. However, when we move toward synthetic analogues, we shift our reliance toward chemical methods to achieve similar structural complexity.
The Power of SPPS Technology
For many of us in the lab, SPPS technology efficiently synthesizes peptides by utilizing a stepwise assembly on a solid support. When we specifically synthesize lanthipeptide analogues using SPPS, we gain the ability to introduce non-natural amino acids or modify the peptide backbone in ways that nature cannot.
One of the most effective strategies I have observed involves the use of orthogonally protected bisamino acids. By performing solid-phase peptide synthesis (SPPS), we can manage the complex ring-closing reactions required to mimic natural lanthionine bridges. The literature from 2022 and beyond has highlighted that Class I lanthipeptides are synthesized by two different enzymes, LanB and LanC, but in a synthetic setting, we replicate this through careful choice of protecting groups and cyclization conditions on-resin.
Navigating the Synthesis of Analogues
When embarking on the synthesis of these complex molecules, the primary challenge is maintaining the integrity of the macrocyclic structure. In my own practical work, I have found that:

Why This Matters
The move toward lanthipeptides as a subject of study is driven by their inherent modularity. Whether you are investigating the stereochemistry of methyllanthionine or attempting to engineer novel precursors, the integration of SPPS allows for rapid iteration. By adopting these methods, we can generate a wide array of lanthipeptides—from simple model systems to complex, multi-ring architectures—that would be otherwise inaccessible through traditional fermentation or biosynthesis alone.
In summary, the pursuit of 2022 lanthipeptide analogue synthesis spps methodologies has democratized access to these unique structures. By leveraging the precision of solid-phase techniques, we are effectively expanding the library of available peptide tools, moving beyond what is naturally occurring to what is synthetically possible. For those of us involved in the hands-on creation of these molecules, the synthesis remains a testament to the power of modern chemical engineering.
