Solid-Phase Synthesis of Head to Side-Chain Tyr-Cyclodepsipeptides Through a Cyclative Cleavage From Fmoc-MeDbz/MeNbz-resins

open access: yesFrontiers in Chemistry, 2020
Cyclic depsipeptides constitute a fascinating class of natural products. Most of them are characterized by an ester formed between the β-hydroxy function of Ser/Thr -and related amino acids- and the carboxylic group of the C-terminal amino acid.

Synthesis of cyclic depsipeptides under direct amide cyclization conditions [PDF]

open access: yes, 2005
This work describes the use of the "direct amide cyclization" (DAC) of dipeptides which contain β-, γ-, or δ-hydroxy acids, obtained by the reaction of the corresponding hydroxy acids with 3-amino-2H-azirines, the so-called "azirine/oxazolone" method ...

mMass as a software tool for the annotation of cyclic peptide tandem mass spectra. [PDF]

open access: yesPLoS ONE, 2012
Natural or synthetic cyclic peptides often possess pronounced bioactivity. Their mass spectrometric characterization is difficult due to the predominant occurrence of non-proteinogenic monomers and the complex fragmentation patterns observed. Even though
