Understanding the Poisoning Mechanisms of Na2O and NaCl on CuO/Al2O3 Catalysts: Toluene Oxidation Performance and Reaction Pathways

open access: yesCleanMat, EarlyView.
Na2O and NaCl inhibit the toluene oxidation over CuO/Al2O3, which arises from the formation of Cu‐O‐Na and O‐Cu‐Cl structures. Cu‐O‐Na and O‐Cu‐Cl structure not only have negative effects on the surface properties of CuO/Al2O3 but also change the reaction pathway. Cu‐O‐Na structure promotes the generation of benzene.

Identification of a New Interesting BAG3 Modulator Able to Disrupt Cancer‐Related Pathways

open access: yesChemMedChem, EarlyView.
Compound 2, identified through in‐house screening and derived from SP18, exhibits high affinity for BAG3, as demonstrated by Surface Plasmon Resonance and docking studies. It induces a dose‐dependent proapoptotic response in HeLa cells, evidenced by increased Annexin V/PI staining, underscoring the triazole scaffold as a promising platform for BAG3 ...

Brucinium benzoate trihydrate

open access: yesActa Crystallographica Section E Structure Reports Online, 2006
The title compound, C23H27N2O4+·C7H5O2−·3H2O contains two brucinium–benzoate ion pairs and six water mol­ecules in the asymmetric unit. In the crystal structure of (I), corrugated layers of brucinium cations, stabilized by weak C—H⋯O and C—H⋯π inter­actions, are separated by anionic/water sheets.

The [3,3]‐Sigmatropic Allyl Cyanate–Isocyanate Rearrangement on Levoglucosenone Derivatives Stereoselectively Provides 4‐Deoxy‐4‐Aminosugars

open access: yesChemistry–Methods, EarlyView.
The Ichikawa rearrangement of allyl cyanates obtained in situ from levoglucosenone‐derived allyl carbamates allows the synthesis of unique 4‐deoxy‐4‐amino‐d‐allose derivatives with complete chirality transfer in a metal‐free three‐step, one‐pot manner.
