Nitric Oxide Decreases the Expression and Activity of the Ubiquitin-Conjugating Enzyme UbcH10
Nick D. Tsihlis, PhD, Chris S. Oustwani, BA, Ashley K. Vavra, MD, Qun Jiang, MD and Melina R. Kibbe, MD

Nitric oxide (NO) has been shown to limit the formation of neointimal hyperplasia in animal models of arterial injury. Ubiquitination proceeds via formation of thioester bonds and NO can act to disrupt those bonds. We report that NO decreases the activity and expression of UbcH10 in vitro, and decreases the expression of UbcH10 following arterial injury in vivo. Therefore, UbcH10 may be a promising therapeutic target for inhibiting neointimal hyperplasia.

SuperNatural: A Database of Available Natural Compounds
Melanie Füllbeck, Mathias Dunkel and Robert Preissner

The majority of marketed drugs are natural compounds or derivatives thereof. The compounds availability is often unclear. Therefore we have compiled a database of ~50,000 natural compounds. Starting point for in silico screenings are about 2,500 well-known, classified natural compounds or imported molecules. Possible medical applications can be detected and about three million conformers computed to account for the flexibility during usage of the 3D-superposition algorithm.

Enzyme kinetic measurements performed on BMG LABTECH´s FLUOstar OPTIMA

BMG LABTECH has developed a new evaluation software feature able to calculate the Km value as well as the maximal velocity (Vmax) from an enzymatic kinetic measurement. Enzymes differ in their affinity to specific substrates and this affinity is represented by the Michaelis-Menten constant Km. The new software feature for enzyme kinetic offers fast and easy calculation of Km and Vmax. Available plots are the common Michaelis-Menten, Lineweaver-Burk, Eadie-Hofstee, Scatchard and Hanes kinetic f

Automated Microreactor Optimisation of the Swern-Moffatt Oxidation at Elevated Temperatures
Pieter J. Nieuwland, Kaspar Koch, Noud van Harskamp, Ron Wehrens, Jan C.M. van Hest and Floris P.J.T. Rutjes

Optimisation of the selective Swern-Moffatt oxidation of benzyl alcohol to benzaldehyde by varying five experimental parameters in an automated microreactor setup.

Organic azide synthesis in microreactors: from optimization to lab scale production
Pieter J. Nieuwland, Bo Hanssen, Kaspar Koch, Paul Janssen, Marielle M.E. Delville, Anton Lunshof and Floris P.J.T. Rutjes

The formation of benzyl azide by diazotransfer to benzyl amine was screened and subsequently scaled up using continuous flow chemistry.

Five noncovalent peptidic ligands show different affinity rankings in solution and gas phase
Andrey Dyachenko , Michael Goldflam , Marta Vilaseca , Ernest Giralt

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.

Synthesis and trafficking of the tonoplast potassium channel AtTPK1
Marie Maitrejean (1,2), Michael Wudick (2), Camilla Voelker (2), Katrin Czempinski (2), Emanuela Pedrazzini (1), Alesandro Vitale (1)

Sorting signals of tonoplast proteins and the pathway they follow through the endomembrane system are still poorly characterized. Using Brefeldin A (an inhibitor of the Golgi-mediated traffic) we showed that a Golgi-dependent pathway for tonoplast delivery may exist. Then we generated various chimeric TPK1-TPK4 fusions, exchanging various domains. We observed that the cytosolic, C-terminal domain of TPK1 is sufficient to re-direct the plasma membrane TPK4 to the tonoplast.

Anti-inflammatory activity of Dalbergia sissoo Roxb. heart-wood
Ohm Devani, S. K. Lahiri, D. D. Santani, M. B. Shah

The heart-wood of Dalbergia sissoo Roxb. is reported to be used in traditional medicinal practices, of which anti-inflammatory is one. The present work evaluates the effect of the heart-wood extract on the carrageenan induced rat paw edema. The drug was found to be active at lowest of 3 doses tried. the drug can be said to posses anti-inflamatory activity but needs further evaluation of discover the pathway of the same.
