The Cyclic Depsipeptide Backbone of the Didemnins

Acta Crystallographica Section C Crystal Structure Communications, 1995
An X-ray crystal analysis of phi-lactone N-¿1-¿N-¿4-¿[3- hydroxy-5-methyl-1-oxo-4-(N-L-threonylamino)heptyl]- oxy¿-2,5-dimethyl-1,3-dioxohexyl¿-L-leucyl¿-L-prolyl¿- N,O-dimethyl-L-tyrosine hydrobromide hydrate (1a), C42H66N5O11+.Br-.H2O, was obtained in order to determine the backbone folding of the macrocycle and to compare the results obtained with ...

Biosynthesis of depsipeptide mycotoxins in Fusarium

European Journal of Plant Pathology, 2002
The cyclic hexadepsipeptide enniatin is known as a phytopathogenic compound from Fusaria causing necrosis and wilt. The molecule consists of three alternating residues each of a branched chain amino acid and D-hydroxyisovaleric acid (D-Hiv). Enniatins are synthesized by a 347kDa multienzyme (enniatin synthetase) via a thiol template mechanism.

The structure-antimicrobial relation of depsipeptides

Experientia, 1963
Die Beziehungen zwischen Struktur und antimikrobieller Aktivitat in der Reihe der Depsipeptide wurden untersucht. Cyclotetradepsipeptide sind praktisch inaktiv. Die grosste Aktivitat besitzen die Cyclohexadepsipeptide mit regularer Oxy- und Aminosaurensequenz.

Synthese geschützter Depsipeptide

Helvetica Chimica Acta, 1960
AbstractThe syntheses and properties of p‐nitrobenzyl diazoacetyl‐glycinate (VI), p‐nitrobenzyl p‐(p‐methoxyphenylazo)‐benzyloxycarbonyl‐glycyl‐glycollyl‐glycinate (II) and p‐nitrobenzyl p‐phenylazo‐benzyloxycarbonyl‐glycyl‐glycollyl‐glycinate are described. These compounds have been prepared as intermediates for the synthesis of other depsipeptides.

Xentrivalpeptides A–Q: Depsipeptide Diversification in Xenorhabdus

Journal of Natural Products, 2012
Seventeen depsipeptides, xentrivalpeptides A-Q (1-17), have been identified from an entomopathogenic Xenorhabdus sp. Whereas the structure of xentrivalpeptide A (1) was determined after its isolation by NMR spectroscopy and the advanced Marfey's method, the structures of all other derivatives were determined using a combination of stable isotope ...

Fungal cyclooligomer depsipeptides

Natural Product Reports, 2011
This review surveys the biological activities and the iterative and recursive biosynthetic mechanisms of fungal cyclooligomer depsipeptides, and their structural diversification by various combinatorial biosynthetic methods.
