Synthesis of Cyclic Peptides Containing a Thioester Handle for Native Chemical Ligation

Thioacids – synthons for amide bond formation and ligation reactions: assembly of peptides and peptidomimetics

The synthesis of α-amino thioacids and peptide thioacids and their applications in chemoselective amide bond formation, ligation of peptides/proteins/glycopeptides and synthesis of peptidomimetics are reviewed.

1,2,4-Triazole-aided native chemical ligation between peptide-N-acyl-N′-methyl-benzimidazolinone and cysteinyl peptide

Novel thiol-additive-free NCL using easy-to-prepare peptide-MeNbz and 1,2,4-triazole can be readily combined with one-pot desulfurization and Cys-modification.

Applications of Chemical Ligation in Peptide Synthesis via Acyl Transfer

The utility of native chemical ligation (NCL) in the solution or solid phase synthesis of peptides, cyclic peptides, glycopeptides, and neoglycoconjugates is reviewed. In addition, the mechanistic details of inter- or intra-molecular NCLs are discussed from experimental and computational points of view.

Examination of mercaptobenzyl sulfonates as catalysts for native chemical ligation: application to the assembly of a glycosylated Glucagon-Like Peptide 1 (GLP-1) analogue

3/4-Mercaptobenzyl sulfonates were investigated as aryl thiol catalysts for native chemical ligation (NCL).

Scaffolded multiple cyclic peptide libraries for protein mimics by native chemical ligation

The accessibility to collections, libraries and arrays of cyclic peptides is increasingly important since cyclic peptides may provide better mimics of the loop-like structures ubiquitously present in and – especially – on the surface of proteins.
