Understanding Solid-Phase Peptide Synthesis (SPPS)

Solid-phase peptide synthesis, often abbreviated as SPPS, is a cornerstone methodology for creating peptides. The fundamental principle involves attaching the C-terminal amino acid of the desired peptide to an insoluble solid support, typically a resin. Subsequent amino acids are then added sequentially in a step-wise fashion, building the peptide chain from the C-terminus to the N-terminus. Each addition cycle involves deprotection of the terminal amino group, coupling of the next protected amino acid, and washing to remove excess reagents.Duramycin (Moli1901) | Antimicrobial Peptide This process allows for the purification of the growing peptide chain simply by washing the resin, significantly simplifying the overall synthesis process compared to traditional liquid-phase methods. Fmoc (9-fluorenylmethyloxycarbonyl) chemistry is a widely adopted strategy within SPPS due to its mild deprotection conditions, which are compatible with a wide range of amino acid side-chain protecting groups.Solid phase peptide synthesis methods and associated ...
