Nouvelles approches synthétiques de prodrogues de cyclosporine A et d'analogues antiviraux

Jérémy Bérard

The cyclosporins comprise a family of cyclic 11-peptides containing seven N-methylated, hydrophobic amino acids. Cyclosporine A (CsA) representing the major member of this family is widely used as immunosuppressive agent in organ transplantations. The biol ...

Micropositioning and microscopic observation of individual picoliter-sized containers within SU-8 microchannels

Jürgen Brugger, Horst Arthur Vogel, Christoph Schreiter

We describe the fabrication and application of a bioanalytical chip, made of SU-8 photoresist, comprising integrated, high aspect-ratio microfluidic channels, suitable to manipulate and investigate vesicles, cell fragments and biological cells. A central m ...

Optimized methods for the enzymatic ligation of oligoribonucleotides and analogues

Frédéric David Meylan

The preparation of oligoribonucleotides is of great interest for structural and functional investigations in biomolecular chemistry and biology. Relevant RNAs are relatively long and contain often modifications. Two methods for their preparation are curren ...

"Switch peptides" : conception et synthèse d'inhibiteurs ou destructeurs potentiels de fibrilles amyloïdes

Lydiane Jeanine Saucède

Despite of considerable progress in the research at the interface of Chemistry, Biology and Medicine, neurodegenerative diseases affect more and more seriously our ageing population and remain a real therapeutic challenge for researcher. Nevertheless, adva ...

New synthetic route toward polyketide-like macrolides

Sandrine Gerber, Gérald Coste

New pathways toward the synthesis of polyketide-like macrolides have been developed through the functionalization of long chain polyolic fragments readily obtained from 3,3'-methylenebis{[6-(benzyloxy)methoxy]cyclohept-3-en-1-ol} derivatives 6. This synthe ...

Water-soluble prodrugs of cyclosporine A with tailored conversion rates

Arnaud Hamel

A novel type of water-soluble prodrugs of cyclosporine A (CsA) is described, featuring a modular system of an enzyme-cleavable group, a solubilizing moiety and a chemodegradable spacer attached to the hydroxyl function of (4R)-4-[(E)-2-butenyl]-4-,N-dimeth ...
