Advanced Science, EarlyView.The AAA+ ATPase Valosin‐containing protein (VCP/p97) regulates protein homeostasis by unfolding ubiquitinated substrates. Here, we describe UTE‐156, a novel irreversible covalent inhibitor that modifies Cys522 in the D2 ATPase motor domain. Although its pharmacochemical limitations preclude immediate therapeutic use, UTE‐156 serves as a valuable ...

Solvent-controlled selective transformation of 2-Bromomethyl-2-methylaziridines to functionalized Aziridines and Azetidines [PDF]
, 2012 The reactivity of 2-bromomethyl-2-methylaziridines toward oxygen, sulfur, and carbon nucleophiles in different solvent systems was investigated. Remarkably, the choice of the solvent has a profound influence on the reaction outcome, enabling the ...

Advanced Science, EarlyView.Photocatalytic treatment of glyphosate herbicide in agricultural wastewater is achieved through the cooperative effect of the local polarization field and dipole field mediated by lattice‐distorted carbon nitride. Glyphosate is completely degraded via selective C─P bond cleavage with a CO evolution rate of 1166 µmol g−1 h−1.

Cation-pi interactions in aromatics of biological and medicinal interest: Electrostatic potential surfaces as a useful qualitative guide [PDF]
, 1996 The cation-pi interaction is an important, general force for molecular recognition in biological receptors. Through the sidechains of aromatic amino acids, novel binding sites for cationic ligands such as acetylcholine can be constructed.

Advanced Science, EarlyView.In this study, a MXene‐based V4C3 nanoplatform, VARH, was constructed, which achieved a photothermal conversion efficiency of 44.21% in the NIR‐II window. This platform integrated photothermal therapy, chemodynamic therapy, and thermodynamic therapy with CRISPR/Cas9‐mediated heat shock protein 90 knock‐out technology.

Advanced Science, EarlyView.We present a mechanochemical, radical‐mediated hydroselenation of alkenes under ambient conditions. This method modularly generates alkyl selenyl radicals from elemental selenium and alkyl (pseudo)halides, utilizing PhSiH3 and H2O as hydrogen atom donors, with the water likely originating from the air and/or trace water present in the reagents ...
