Understanding the Foundation: Lanthipeptides and SPPS
Lanthipeptides are a unique class of ribosomally synthesized and post-translationally modified peptides (RiPPs) known for their distinctive thioether bridges. Historically, Lanthipeptides are synthesized from a genetically encoded precursor peptide, LanA, which requires complex enzymatic processing. However, the chemical synthesis of these molecules offers a pathway to create novel analogues that may A Novel Hybrid SPPS/LPPS Strategy for the Synthesis of not be accessible through biological systems alone.
Solid-phase peptide synthesis (SPPS) has become the method of choice for the preparation of these complex structures. SPPS technology efficiently synthesizes peptides by the stepwise assembly of amino acids on a solid support.

The Shift Toward Green Chemistry
A major theme in 2024 is the transition toward sustainable manufacturing. Traditional SPPS relies heavily on solvents like dimethylformamide (DMF), which poses environmental challenges. Recent studies have introduced aqueous-based methods and nanoassembly-enabled techniques to perform solid-phase peptide synthesis (SPPS) in a more eco-friendly manner. These protocols ensure that the synthesis of lanthipeptides remains scalable without compromising the structural integrity of the final product.
Engineering and Design Considerations
When designing a lanthipeptide analog, the chemist must carefully consider the placement of the thioether bridges. The use of orthogonally protected bisamino acids during solid-phase peptide synthesis (SPPS) allows for the selective formation of these bridges.
* Hybrid Approaches: Some of the most successful projects this year have employed a hybrid strategy, combining SPPS with solution-phase methods. This allows for the coupling of large, unprotected peptide fragments in aqueous media.
* Chemoselectivity: Modern synthesis protocols now emphasize chemoselective reactions, ensuring that the analogue retains its intended configuration throughout the assembly process.
