Dearomative Allylation of Aromatic Cyanohydrins by Palladium Catalysis: Catalyst-Enhanced Site-Selectivity [PDF]

, 2020
A dearomative allylation of aromatic cyanohydrins with allyl borates and allyl stannanes under palladium catalysis was developed. At the initial stage of this study, the dearomative reaction (C4-substitution of the aromatics) was competing with benzyl ...

Importin 7 mediates the nuclear import of HIV‐1 integrase via a specific interacting interface

FEBS Open Bio, EarlyView.
HIV‐1 integrase enables viral DNA integration into the host genome. By binding to the core domain of the host protein Importin 7 via its C‐terminal domain, the integrase is transported across the nuclear membrane into the nucleus, where integration of the viral genome into host DNA takes place. This translocation is a critical step for subsequent viral

Recent advances in Sonogashira coupling under green and sustainable conditions

Results in Chemistry
The Sonogashira–Hagihara coupling remains one of the most versatile methods for constructing C(sp2)–C(sp) bonds, yet conventional protocols rely on toxic solvents, copper co-catalysts, and high palladium loadings that limit their sustainability.

Advances in organometallic and protein chemistry [PDF]

, 2010
This thesis describes two areas of scientific investigation. The first contains a description of a study on the synthesis of biotinylated and fluoresceinylated bromomaleimide based reagents. Upon synthesis, the ability of these reagents to add reversibly

Chronobiology of Cancer: How Aging Fuels Oncogenesis at the Molecular Level

Aging and Cancer, EarlyView.
This graphical abstract illustrates the key biological pathways linking aging with cancer development and progression. In the upper left, cumulative exposure to ultraviolet radiation, toxins, and reactive oxygen species (ROS) causes DNA damage and genomic instability, whereas age‐related decline in repair mechanisms, such as ATM/ATR, BER, and NER ...

Intermediate Resistive State in Wafer‐Scale Vertical MoS2 Memristors Through Lateral Silver Filament Growth for Artificial Synapse Applications

Advanced Functional Materials, EarlyView.
In MOCVD MoS2 memristors, a current compliance‐regulated Ag filament mechanism is revealed. The filament ruptures spontaneously during volatile switching, while subsequent growth proceeds vertically through the MoS2 layers and then laterally along the van der Waals gaps during nonvolatile switching.

Pd-catalyzed deuteration of aryl halides with deuterium oxide

Nature Communications
Late-stage deuteration of aryl halides with deuterium oxide is a highly desirable but challenging transformation, primarily due to the difficulty of activating inert carbon-halogen bonds and the umpolung of deuterium oxide in the presence of various ...
