Photochemical reactions of biomass derived platform chemicals.

Platform chemicals obtained from biomass will play an important role in chemical industry. Already existing compounds or not yet established chemicals are produced from this renewable feedstock. Using photochemical reactions as sustainable method for the conversion of matter furthermore permits to develop processes that are interesting from the ecological and economical point of view.

Fluorescent probe for the detection of acetylcholinesterase inhibitors using high performance thin layer chromatography effect-directed assay in complex matrices.

In recent years Bioautography has become an efficient bioassay for finding active compounds in complex matrices including extracts of; bacteria, plants or fungi. High Performance Thin Layer Chromatography (HPTLC) is a technique which allows effect-directive analysis (EDA) through the separation and identification of biologically active substances on a Thin Layer Chromatography (TLC) plate and can be run as a high throughput screening assay for enzymes. This paper presents a new bioautography method using a novel fluorescent probe derived from coumarin and its validation with Acetylcholinesterase (AChE) inhibition.

Design, synthesis and biological evaluation of conformationnally-restricted analogues of E7010 as inhibitors of tubulin assembly (ITA) and vascular disrupting agents (VDA).

Vascular-disrupting agents (VDA) specifically target established neovasculature which results in vascular shutdown. This therapeutic strategy could improve the outcome of pathologies involving aberrant angiogenesis. Although several classes of VDA exist, inhibitors of tubulin assembly (ITA) represent the main category.
