Abstract
Cyclodepsipeptides (CDPs) represent a huge family of chemically and structurally diverse molecules with a wide ability for molecular interactions. CDPs are cyclic peptide-related natural products made up of both proteinogenic and nonproteinogenic amino acids linked by amide and ester bonds. The combined use of different analytical methods is required to accurately determine their integral structures including stereochemistry, thus allowing deeper insights into their often-intriguing bioactivities and their possible usefulness. Our goal is to present the various methods developed to accurately characterize CDPs. Presently, Marfey's method and NMR (nuclear magnetic resonance) are still considered the best for characterizing CDP configuration. Nevertheless, electrospray-high resolution tandem mass spectrometry (ESI-HRMS/MS) is of great value for efficiently resolving CDP's composition and sequences. For instance, recent data shows that the fragmentation of cationized CDPs (e.g., [M + Li]+ and [M + Na]+) leads to selective cleavage of ester bonds and specific cationized product ions (b series) useful to get unprecedented sequence information. Thus, after a brief presentation of their structure, biological functions, and biosynthesis, we also provide a historic overview of these various analytical approaches as well as their advantages and limitations with a special emphasis on the emergence of methods based on HRMS/MS through recent fundamental works and applications.

Isolation, mass spectrometric characterization, and protein phosphatase inhibition properties of cyclic peptide analogues of gramicidin-S from Bacillus brevis (Nagano strain).

Abstract
Six substitutional variants of gramicidin-S, present in a commercial extract of Bacillus brevis, have been characterized using a combination of liquid chromatographic/mass spectrometric analysis of the crude extract, plus accurate mass measurements, tandem mass spectrometric investigations, and amino acid analyses, of isolated high-performance liquid chromatographic fractions. Two of these variants were shown previously (Nozaki and Muramatsu, J. Antibiotics 37, 689 (1984)) to involve replacement of one or both Val residues in gramicidin-S by aminobutyric acid, and these findings are confirmed here. One of the four unknown variants corresponds to substitution of one Val residue by Leu, while the other three all involve substitution of one of the Orn residues in gramicidin-S by Lys, or by citrulline (gamma-carbamoyl ornithine), or by gamma-formyl ornithine. The biological activities of the purified fractions were assessed with respect to their in vitro inhibition of protein phosphatases PP1 and PP2A. For both protein phosphatases inhibition levels fell in the micromolar range, about four orders of magnitude higher than IC50 values for other small cyclic peptides such as microcystins and nodularins.
