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 ...

Synthese geschützter Depsipeptide
Helvetica Chimica Acta, 1960AbstractThe 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.

Siamese Depsipeptides: Constrained Bicyclic Architectures
Angewandte Chemie, 2009has been designed. Cyclic depsipeptide dimers connected by a CC bond were constructed. Two kind of possible connections can be envisaged, those that share a side chain bond or those that share a backbone bond. Owing to the resulting proximity of both structurally identical cycles, they can be called Siamese depsipeptides. For Siamese depsipeptides, the

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 ...
