Stability of noncovalent complexes of VEGF protein with 5 peptidic ligands is studied. Experiments were conducted in solution (NMR CSP, ITC) and in gas phase (CID TOF MS). Each ligand differs from others in chirality of one amino acid. It was shown, that trend of stability of the studied noncovalent complexes is reversed in the gas phase relatively to the solution. An explanation of this behavior is presented.

The combination of flow chemistry and microwave heating offers a unique opportunity to scale out heterogeneous microwave-assisted organic reactions. The feasibility of this setup is depending on the presence of a microwave effect, safety issues and energy efficiency.

Metal-organic frameworks (MOFs) are an emerging class of new nano-porous materials of considerable academic and industrial interest due to their potential applications in gas storagechiral separations and catalysis. MOFs are prepared from the self-assembly of metal ions (nodes) and organic ligands (spacers), where the structural topology of the resulting crystalline frameworks is driven by the co-ordination preferences of these nodes and spacers. MOFs offer opportunities not available to more cl

A new exposure system for the in vitro detection of GHz field effects on neuronal networks
Philipp J. Koester, Jan Sakowski, Werner Baumann, Hans-Walter Glocka, Jan Gimsa. University of Rostock

Different ideas exist about possible targets for biological effects of electromagnetic fields (EMF). One of the favourite systems are the membranes of nerve cells, e.g. in the central nervous system. Our aim is to clarify whether EMF exposure may induce athermal effects. In the experiments, direct electrophysiological in vitro measurements are conducted on neuronal networks exposed to EMF, i.e. possible changes in the action potential patterns produced by the networks are detected. The technique

Microwave-Assisted Rapid Access to Bio-active Heterocycles
Vivek Polshettiwar and Rajender S. Varma. US EPA

Environmentally benign protocols have been developed for the synthesis of various pharmaceutically active heterocycles namely 1,3,4-oxadiazoles, 1,3,4-thiadiazoles, 1,3-dioxanes, pyrazoles, hydrazones and 3,4-dihydropyrimidin-2(1H)-ones, which proceed under the influence of microwave irradiation and using eco-friendly conditions. These greener protocols were catalyzed efficiently by solid supported Nafion®NR50, phosphorus pentasulfide on alumina under solvent-free conditions.

New Accessories for High Throughput and Combinatorial Approach in a Microwave Batch Reactor
Alexander Stadler, Thomas Karner, Matthias Treu. Anton Paar, Boehringer Ingelheim

A unique sealable well-plate system is introduced allowing screening reactions in a 8x6 well format with operation limits of 200°C and 20 bar and a reaction volume of 0.3 mL per well. An appropriate turntable enables to proceed up to 4 of these SiC well plates in one run resulting in 192 parallel reactions at a time. Reaction control is achieved by sensing the IR temperature of the plate surface.
