Electrocatalytic C–H Activation

open access: yesACS Catalysis, 2018
C–H activation has emerged as a transformative tool in molecular synthesis, but until recently oxidative C–H activations have largely involved the use of stoichiometric amounts of expensive and toxic metal oxidants, compromising the overall sustainable nature of C–H activation chemistry.

Strain Release in CH Bond Activation? [PDF]

open access: yesAngewandte Chemie, 2009
What a relief! In 1955 the principle of strain release was put forward to explain the differing reactivity of axial and equitorial alcohols during oxidation. Our findings suggest that this same rationale may account for the differing rates of activation between axial and equitorial C–H bonds in C–H activation processes.

C−H Bond Activation by Iridium(III) and Iridium(IV) Oxo Complexes [PDF]

open access: yes, 2023
Oxidation of an iridium(III) oxo precursor enabled the structural, spectroscopic, and quantum-chemical characterization of the first well-defined iridium(IV) oxo complex.

Effect of DFPP on Ferroptosis in Peripheral Blood CD14+ Monocytes of Hyperlipidemic Patients Involving the ACSL4/LPCAT3/ALOX5 Pathway

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Hyperlipidemia is a major risk factor for atherosclerotic cardiovascular disease (ASCVD). Although statins are the cornerstone of lipid‐lowering therapy, their use may be limited in some patients by adverse effects. This study evaluated the possible impact of non‐drug treatment using double‐filtration plasmapheresis (DFPP) on CD14+

The human gut microbiome across the life course

open access: yesFEBS Letters, EarlyView.
Despite significant individual variation and continuous change throughout life, the human gut microbiome follows some life stage‐specific trends. This article provides a brief overview of how gut microbiome composition shifts across different phases of life. Created in BioRender. Özkurt, E. (2026) https://BioRender.com/8q4nrnc.

Visible light-driven C−H activation and C–C coupling of methanol into ethylene glycol

open access: yesNature Communications, 2018
Direct transformation of methanol into two- or multi-carbon compounds is extremely attractive but remains a challenge. Here, the authors report an efficient photocatalytic route to the transformation of methanol into ethylene glycol and hydrogen over a ...

Degradation mechanism of the von Willebrand factor A2 domain by nattokinase

open access: yesFEBS Letters, EarlyView.
Nattokinase, a natto‐derived protease, exhibits potent antithrombotic effects. This study demonstrates that nattokinase directly cleaves the von Willebrand factor (vWF) A2 domain in vitro. Unlike the native regulator ADAMTS13, nattokinase degrades folded vWF independently of shear stress.

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

open access: yesFEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Enantioselective Double C−H Activation of Dihydronaphthalenes

open access: yes, 2016
Dirhodium tetrakis((S)-N-dodecylbenzenesulfonyl)prolinate) (Rh2(S-DOSP)4) catalyzed reaction of 1,2-dihydronaphthalenes with an excess of methyl vinyldiazoacetates results in a formal double C−H activation, generating four new stereogenic centers with ...

Recent Developments in Transition-Metal Catalyzed Direct C–H Alkenylation, Alkylation, and Alkynylation of Azoles

open access: yesMolecules, 2020
The transition metal-catalyzed C–H bond functionalization of azoles has emerged as one of the most important strategies to decorate these biologically important scaffolds. Despite significant progress in the C–H functionalization of various heteroarenes,
