Direct Coumarin Synthesis by Gold Catalyzed Hydroarylation of Alkynoic Acids/Esters
ChemCatChem, EarlyView.Gold‐catalyzed, direct hydroarylation of alkynoic acids (or esters) with phenols in a small amount of an ionic liquid as solvent and reaction promoter provides an efficient pathway for the one‐pot preparation of coumarins. This synthetic methodology is highly atom efficient, works with <1 mol% gold and the catalytic system is recyclable.

Organocatalytic Switches of DNA Glycosylase OGG1 Catalyze a Highly Efficient AP‐Lyase Function
Chemistry – A European Journal, EarlyView.Organocatalytic switches are small molecules that combine active site affinity and a nitrogen‐centered base for catalysis, effectively removing the rate‐determining step of the OGG1 biochemical cascade. Here, we identify a minimal structure and modulate the active nitrogen pKa, enabling the catalysis of ultrafast AP site incisions in a range of pH ...

Chemistry – A European Journal, EarlyView.The insertion of a fluorescent coumarin unit by using a lysine‐based linker on deferoxamine leads to a chelating agent (DFOKC), whose Cu(II) and Zr(IV) complexes can be used for both optical imaging and positron emission tomography. DFOKC shows increased binding ability for Cu(II) and Zr(II) and improved tumor cell internalization via pinocytosis ...

Canadian Journal of Statistics, EarlyView.Abstract Modern longitudinal data from wearable devices consist of biological signals at high‐frequency time points. Distributed statistical methods have emerged as a powerful tool to overcome the computational burden of estimation and inference with large data, but methodology for distributed functional regression remains limited.

Cytoskeleton, EarlyView.ABSTRACT Actin filaments are dynamic polymers whose length depends on regulated monomer association and dissociation at their ends. Actin barbed‐end dynamics are relatively better understood, primarily due to the approximately tenfold faster subunit on/off rates at barbed versus pointed ends.

Lacustrine and fan‐delta sediments in syn‐rift lake basins
The Depositional Record, EarlyView.A consistent model for the sequence framework and depositional pattern of asymmetric half‐grabens in syn‐rift lake basins bounded by active faults has been established, complementing existing models for marine rift successions. Syn‐rift lake basins are characterised by relatively small dimensions, steep slopes, poorly developed shoreline strata ...
