Marine Depsipeptides as Promising Pharmacotherapeutic Agents

Current Protein & Peptide Science, 2016
Depsipeptides are a group of biologically active peptides that have at least one of the amide bonds replaced by an ester bond. These peptides sometimes present additional chemical modifications, including unusual amino acid residues in their structures.

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 ...

Zur Synthese cyclischer Depsipeptide

Chemische Berichte, 1966
AbstractSynthesen linearer Tetradepsipeptide mit D‐Valin und α‐D‐Hydroxy‐isovaleriansäure als Bausteinen (vom Typ 8 bzw. 11 bzw. 16) werden beschrieben. Die Cyclisierung gelingt nur durch Herstellung einer Amidbindung mittels der Säurechloridmethode, und sie ergibt unter Dimerisierung das Cyclooctadepsipeptid.

Die Chemie der Depsipeptide

Angewandte Chemie, 1960
AbstractGegenwärtig ist eine bedeutende Anzahl natürlicher Depsipeptide (Verbindungen, die aus ester‐ und amidartig miteinander verknüpften α‐Hydroxy‐ und α‐Aminosäuren bestehen) bekannt. Diejenigen Depsipeptide, deren Konstitution aufgeklärt werden konnte, haben eine cyclische Struktur.

The structure-antimicrobial relation for valinomycin depsipeptides

Experientia, 1965
Auf Grund eines grossen Vergleichsmaterials wurden die Strukturelemente, die fur die antimikrobielle Aktivitat der Cyclodepsipeptide notig sind, ermittelt. Insbesondere wurden Ringgrosse, Ersatz der Ester- oder N-Methylamid-Gruppe durch eine Amidgruppe, strukturelle und konfigurative Anderung der Aminosaure- und Hydroxysaurereste studiert.

Synthesis of ornithine-containing depsipeptides

Chemistry of Natural Compounds, 1972
The reaction of Nα-benzyloxycarbonyl-Nδ-formyl-L-ornithine with α-hydroxy esters has been studied and conditions have been found under which aminoacylation takes place in high yield.

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 ...
