Discovery and Biosynthesis of Gladiolin: A Burkholderia gladioli Antibiotic with Promising Activity against Mycobacterium tuberculosis

Stewart Cole, Anthony Vocat, Ruben Hartkoorn

An antimicrobial activity screen of Burkholderia gladioli BCC0238, a clinical isolate from a cystic fibrosis patient, led to the discovery of gladiolin, a novel macrolide antibiotic with potent activity against Mycobacterium tuberculosis H37Rv. Gladiolin i ...

Dissymmetrical Double-Chain Elongation Approach to the Asymmetric Synthesis of Long-Chain Polypropionates

Claudia Jana Exner

Polyketides show interesting biological activities and therefore represent an important class of natural products. The necessity of their diastereo- and enantioselective synthesis led to the development of numerous methodologies. A brief overview of this t ...

Total Synthesis of Dolabriferol and Polypropionate Fragments Applying New Organic Chemistry of Sulfur Dioxide

Polypropionates are common products of metabolism in bacteria, insects, fungi and marine organisms. They constitute an important class of products with a wide range of interesting biological activities. Our group has shown previously that 1-alkoxy-3-acylox ...

Total asymmetric synthesis of glycomimetics and polypropionates of biological interest

Pierre Vogel

Using readily available chiral auxiliaries such as (+)- and (-)-camphanic acid, (R,R)- and (S,S)-tartaric acid derivatives (e.g. RADO(R)-COCl, SADO(R)-COCl) efficient diastereoselective syntheses of rare sugars and glycomimetics have been developed. They e ...

Spongistatins : biological activity and synthetic studies

Pierre Vogel, Sandrine Gerber

During the last two decades, marine organisms such as sponges, tunicates, softcoral and starfish proved to be productive sources of structurally complex metabolites presenting unprecedented architectures.[1] These marine natural products often display unex ...

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 ...
