WebPeptides are synthesized chemically either in solution or on a solid phase. The process involves directed and selective formation of an amide bond between an N-protected amino acid and an amino acid bearing a free amino group and protected carboxylic acid. In solid phase synthesis, the carboxyl protecting group is linked to a polymer support. WebApr 11, 2024 · In this study, we report an optimized Fmoc solid-phase synthesis of KIIIA using various strategies. Our results indicate that free random oxidation is the simplest method for peptides containing triple disulfide bonds, resulting in high yields and a simplified process.

The resultant acyloxazolidine is stable to base and is compatible with Fmoc protocols. For peptides containing a C-terminal aspartal, argininal, leucinal, phenylalaninal, or valinal residue, pre-loaded resins are available.
WebTemporary internal (structural) modifications of the peptide sequence have revolutionized the use of the Fmoc-based SPPS protocol on “difficult sequences.” Today several different backbone modifications exist mainly focused to prevent side-reaction such as diketopiperazine or aspartimide formation ( Paradis-Bas et al., 2016 ).
