When conducting these protocols, I often emphasize:
* Coupling Efficiency: Ensuring high-yield couplings is vital for long sequences.
* Cyclization: The formation of the lanthionine ring—a hallmark of lanthipeptide chemistry—requires careful control of intramolecular cyclization conditions.
* Cleavage and Purification: The entire SPPS sequence, from the first amino acid attachment to final purification, can often be optimized to fit within a 10–12 day window, depending on the complexity of the target.
Current Trends and Methodological Shifts
It is worth noting that SPPS has become the method of choice for the preparation of peptides on both the milligram and multi-kilogram scale. However, we are also seeing a convergence between synthetic chemistry and biocatalysis. The recent emergence of cell-free biosynthesis and engineering of ribosomally synthesized lanthipeptides offers a complementary approach to traditional chemical methods. By utilizing cell-free gene expression, researchers are now able to rapidly engineer variants that would be prohibitively expensive to produce via purely synthetic routes.
From my perspective, the most exciting developments involve hybrid a by A Jalan · 2025 · Cited by 5 — This method enables the chemoselective coupling of two unprotected peptide fragments in aqueous media without epimerization, offering a powerful pproaches.
