Chemistry - A European Journal, 2000
The convergent synthesis of a new class of chiral dendrimers is described. Owing to their structural resemblance to depsipeptides they are called depsipeptide dendrimers. The ex-chiral pool synthesis starts from (R,R)-, (S,S)-, and meso-tartaric acid as branching units and dipeptides or tripeptides consisting of glycine, (L)-alanine, and (L)-leucine as

Antimitotic Peptides and Depsipeptides
Current Medicinal Chemistry-Anti-Cancer Agents, 2012Tubulin is the target for an ever increasing number of unusual peptides and depsipeptides that were originally isolated from a wide variety of organisms. Since tubulin is the major component of cellular microtubules, which maintain cell shape in interphase and form the mitotic spindle, most of these compounds are highly toxic to mammalian cells.

Recent Developments in Depsipeptide Research
Current Medicinal Chemistry, 2002This review focuses on the major developments in depsipeptide research since 1995. Depsipeptides are bio-oligomers composed of hydroxy and amino acids linked by amide and ester bonds. Many depsipeptides show very promising biological activities, including anticancer, antibacterial, antiviral, antifungal, anti-inflammatory, and anti-clotting or anti ...

Small depsipeptides as solvent gelators
Journal of the Chemical Society, Chemical Communications, 1993The formation of very thermostable gels with several solvents is reported for two cyclic depsipeptides of comparatively low molecular mass.

Progress in Depsipeptide‐Based Biomaterials
Macromolecular Bioscience, 2010AbstractPolydepsipeptides – alternating copolymers of an α‐amino acid and an α‐hydroxy acid – are a group of biodegradable polymers. Versatile polydepsipeptides with or without pendant functional groups, as well as various polymer architectures, for example, providing alternative, random, diblock, triblock, multiblock or graft sequence structures, can ...

The Cyclic Depsipeptide Backbone of the Didemnins
Acta Crystallographica Section C Crystal Structure Communications, 1995An 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 ...

The cyclization of peptides and depsipeptides
Journal of Peptide Science, 2003AbstractConstricting the peptide backbone into a more defined conformational form through cyclization is an activity evolved in nature and in synthetic work, the latter straddling only the most recent decades. The resulting conformational constraints increase the probability of an optimum response with bio‐receptors.

The structure-antimicrobial relation of depsipeptides
Experientia, 1963Die 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.
