Z-REX uncovers a bifurcation in function of Keap1 paralogs

Yimon Aye, Xuyu Liu, Jesse Poganik, Yi Zhao, Alexandra Krina Van Hall-Beauvais, Kuan-Ting Huang

Studying electrophile signaling is marred by difficulties in parsing changes in pathway flux attributable to on-target, vis-& agrave;-vis off-target, modifications. By combining bolus dosing, knockdown, and Z- REX & mdash;a tool investigating on- target/on ...

Synthesis, characterization and cytotoxicity of arene-ruthenium(II) complexes with acylpyrazolones functionalized with aromatic groups in the acyl moiety

Paul Joseph Dyson, Rosario Scopelliti, Tina Riedel

A series of neutral ruthenium(II)-arene complexes, [(arene) Ru(Q(R))Cl] (arene = p-cymene or hexamethylbenzene), containing 4-acyl-5-pyrazolonate (Q(R)) ligands with aromatic substituents in the acyl moiety (a phenyl in Q(Ph) and a 1-naphthyl in Q(naph)) a ...

Analysis and Removal of Product Gas Contaminants Present in Gasification Processes

Sven Philip Edinger

Energy demand and economic development are intrinsically linked. Earlier economic development came at the price of serious environmental pollution, posing a risk to life on earth. Thus, a transition from fossil to renewable energy is needed. Among the rene ...

Organocatalytic Enantioselective Vinylogous Pinacol Rearrangement Enabled by Chiral Ion Pairing

Qian Wang, Jieping Zhu, Hua Wu

An enantioselective pinacol rearrangement of functionalized (E)-2-butene-1,4-diols was developed. In the presence of a catalytic amount of a chiral BINOL-derived N-triflyl phosphoramide, these 1,4-diols rearranged to b,g-unsaturated ketones in excellent yi ...

On-line liquid quench sampling and UV–Vis spectroscopy for tar measurements in wood gasification process gases

Christian Ludwig, Rudolf Paul Wilhelm Jozef Struis

In biomass gasification processes, the formation and handling of tars are of major concern. Robust and versatile analytical tools are needed to on-line monitor tar compound concentrations in process gases from lab- to industrial scale. This study addresses ...

The Impact of Toluene on the Performance of Anode-Supported Ni-YSZ SOFC Operated on Hydrogen and Biosyngas

Jan Van Herle, Christian Ludwig, Stefan Diethelm, Hossein Madi

This paper presents an experimental study of the impact of toluene on the performance of anode-supported (AS) Ni/YSZ SOFC operating at ∼800 °C, 0.25 A/cm2 fed with H2 and biosyngas. Toluene was added to the fuel stream and its concentration increased from ...

An Efficient One-Step Synthesis of Piperidin-2-yl and Pyrrolidin-2-yl Flavonoid Alkaloids through Phenolic Mannich Reactions

Qian Wang

An efficient one-step synthesis of piperidin-2-yl and pyrrolidin-2-yl flavonoid alkaloids was achieved in good to excellent yields by a highly regioselective phenolic Mannich reaction of chrysin with cyclic imines or iminium salts. Performing the reaction ...

Metalation of 2-Heterosubstituted Naphthalenes at the 1- or 3-Position: Factors That May Determine the Regiochemistry

Upon metalation and subsequent electrophilic trapping, 2-fluoronaphthalene inevitably gives rise to regioisomeric mixtures in varying proportions, whereas 2-(trifluoromethyl) naphthalene undergoes deprotonation either at the 1- or the 3-position, depending ...

Quantification of biodegradation for o-xylene and naphthalene using first order decay models, Michaelis-Menten kinetics and stable carbon isotopes

At a former wood preservation plant severely contaminated with coal tar oil, in situ bulk attenuation and biodegradation rate constants for several monoaromatic (BTEX) and polyaromatic hydrocarbons (PAH) were determined using (1) classical first order deca ...

Comparison of naphthalene bioavailability determined by whole-cell biosensing and availability determined by extraction with Tenax

Jan Roelof van der Meer, Stefanie Kohlmeier, Robin Tecon

A rapid biological method for the determination of the bioavailability of naphthalene was developed and its value as an alternative to extraction-based chemical approaches demonstrated. Genetically engineered whole-cell biosensors are used to determine bio ...
