Conformational studies of destruxins, insecticidal cyclodepsipeptides. [PDF]

Agricultural and Biological Chemistry, 1976
The solution conformations of protodestruxin, desmethyldestruxtn B and destruxin B, insecticidal cyclodepsipeptides, in DMSO-d6 have been studied through the use of 100–MHz proton NMR spectroscopy. Proton-deuteron exchange and temperature dependence of the peptide proton chemical shift were used to delineate peptide protons in terms of exposure to ...

Origin and characterization of cyclodepsipeptides: Comprehensive structural approaches with focus on mass spectrometry analysis of alkali-cationized molecular species. [PDF]

Mass Spectrom Rev
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.

Insecticidal cyclodepsipeptides from Metarhizium anisopliae

Journal of the Chemical Society, Perkin Transactions 1, 1989
Bioassay-guided fractionation of the culture broth of Metarhizium anisopliae resulted in the isolation of 10 insecticidal cyclodepsipeptides–the destruxins, including two new compounds, destruxin E2 and chlorohydrin. Complete 1H and 13C n.m.r. assignments for the major destruxins, A and B, by various 1 D and 2D n.m.r.
