Synthesis of Natural and Unnatural Cyclooligomeric Depsipeptides Enabled by Flow Chemistry [PDF]

open access: yesChemistry - A European Journal, 2016
Flow chemistry has been successfully integrated into the synthesis of a series of cyclooligomeric depsipeptides of three different ring sizes including the natural products beauvericin (1 a), bassianolide (2 b) and enniatin C (1 b).

Depsipeptide Dendrimers

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, 2012
Tubulin 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, 2002
This 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, 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.

Progress in Depsipeptide‐Based Biomaterials

Macromolecular Bioscience, 2010
AbstractPolydepsipeptides – 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 ...
