Identification of Cyclic Depsipeptides and Their Dedicated Synthetase from Hapsidospora irregularis
Seven cyclic depsipeptides were isolated from Hapsidospora irregularis and structurally characterized as the calcium channel blocker leualacin and six new analogues based on the NMR and HRESIMS data. These new compounds were named leualacins B–G.

Structure of New Cyclic Depsipeptides, Bu-2841-08 and -10
The structures of new antibiotics, Bu-2841-08 and -10, have been determined. They are cyclic depsipeptides and the sequence of amino acid residues was established by mass spectral analysis of the hydrolyzed linear peptide and NMR spectral analysis of the parent cyclic peptides.

Synthesis of conformationally restricted cyclic hexadepsipeptides via direct amide cyclization
Ring closure by direct amide cyclization was used in the synthesis of 19-membered cyclic depsipeptides 27 (Schemes1 and 3). The linear hexapeptide precursors 4, containing the beta-hydroxy acid 3-hydroxy-2-phenylpropanoic acid (Tro), and five alpha-amino

Adsorption of cyclic depsipeptide mycotoxins to glass
During analytical processes, adsorption of peptides, which is believed to mostly be due to non-covalent interactions and depending upon the experimental conditions, cannot only lead to significant loss of the analyte, but also to increased analytical variability. This undesirable aspect, however, has been given scant attention [1-2].
