Acid-base-induced fac → mer isomerization of luminescent iridium(iii) complexes

Kay Severin, Farzaneh Fadaei Tirani, Albert Ruggi, Anastasia Gitlina, Carolina Luciana Plaice

Luminescent Ir(C^N)3 complexes (C^N = cyclometalated arylpyridine ligand) exist in the form of two stable isomers with distinct photophysical and electrochemical properties: fac and mer. Herein, we show that fac-Ir(C^N)3 complexes can be converted into the ...

Oxygen evolution reaction catalyzed by first-row transition metal oxides: stability and mechanism

Aliki Moysiadou

Water splitting offers the opportunity for storing solar energy and, thus, producing carbon-neutral and renewable solar fuels. The process, known as artificial photosynthesis, is limited by the electrocatalytic conversion of water into molecular oxygen. El ...

Control Theory Concepts for Modeling Uncertainty in Enzyme Kinetics of Biochemical Networks

Vassily Hatzimanikatis, Ljubisa Miskovic, Georgios Savoglidis, Milenko Tokic

Analysis of the dynamic and steady-state properties of biochemical networks hinges on information about the parameters of enzyme kinetics. The lack of experimental data characterizing enzyme activities and kinetics along with the associated uncertainties i ...

Particle-Based Simulation Reveals Macromolecular Crowding Effects on the Michaelis-Menten Mechanism

Vassily Hatzimanikatis, Daniel Robert Weilandt

Many computational models for analyzing and predicting cell physiology rely on in vitro data collected in dilute and controlled buffer solutions. However, this can mislead models because up to 40% of the intracellular volume-depending on the organism, the ...

Identification of the enzymes that determine the robustness of lipid profiles in yeast

Vassily Hatzimanikatis, Howard Riezman, Georgios Savoglidis, Sofia Tsouka

Lipids play a very important role in cell structure and function, as well as in the physiopathology of many diseases. Maintenance of the lipid profiles should be tightly regulated as it is very important for preserving membrane permeability, cell integrity ...

Carbon supported gold and silver: Application in the gas phase hydrogenation of m-dinitrobenzene

Lioubov Kiwi, Fernando Cardenas Lizana

We have studied the gas phase continuous hydrogenation of m-dinitrobenzene (m-DNB) over acid treated activated carbon (AC) supported Au and Ag prepared by deposition-precipitation. Temperature programmed reduction of a 1%wt. metal loading generated a broad ...

Proteome-Wide Profiling of Targets of Cysteine reactive Small Molecules by Using Ethynyl Benziodoxolone Reagents

Jérôme Waser, Chao Wang, Reto Frei, Durga Prasada Rao Hari

In this study, we present a highly efficient method for proteomic profiling of cysteine residues in complex proteomes and in living cells. Our method is based on alkynylation of cysteines in complex proteomes using a clickable alkynyl benziodoxolone bearin ...

Observation of Oscillatory Surface Reactions of Riboflavin, Trolox, and Singlet Oxygen Using Single Carbon Nanotube Fluorescence Spectroscopy

Ardemis Anoush Boghossian

Single-mol. fluorescent microscopy allows semiconducting single-walled carbon nanotubes (SWCNTs) to detect the adsorption and desorption of single adsorbate mols. as a stochastic modulation of emission intensity. In this study, we identify and assign the s ...

Catalytic Formal Homo-Nazarov Reaction and Other Cyclizations of Cyclopropanes

Filippo De Simone

The increasing progress in medicinal chemistry and chemical biology requires more versatile synthetic strategies for the generation of libraries of active compounds and theirs analogues. A wide range of biologically active natural and synthetic compounds c ...

Chiral Phosphoric Acid-Catalyzed Enantioselective Three-Component Povarov Reaction Using Enecarbamates as Dienophiles: Highly Diastereo- and Enantioselective Synthesis of Substituted 4-Aminotetrahydroquinolines

Jieping Zhu

A chiral phosphoric acid (5)-catalyzed three-component Povarov reaction of aldehydes 2, anilines 3, and enecarbamates 4 afforded cis-4-amino-2-aryl(alkyl)-1,2,3,4-tetrahydroquinolines 1 in high yields with excellent diastereoselectivities (>95%) and almost ...
