Novel Tricarbonylrhenium-Anthrapyrazole Complexes with DNA-Binding and Antitumor Properties: In Vitro and In Vivo Pharmacokinetic Studies with ^99mTc-Analogue

Inorganics
Organometallic complexes of fac-tricarbonylrhenium have been shown to exhibit anticancer properties. Anthrapyrazole anticancer agents act as DNA intercalators and topoisomerase IIα inhibitors, leading to double-strand breaks (DBS) and cell cycle arrest ...

Beyond Presumptions: Toward Mechanistic Clarity in Metal‐Free Carbon Catalysts for Electrochemical H2O2 Production via Data Science

Advanced Materials, EarlyView.
Metal‐free carbon catalysts enable the sustainable synthesis of hydrogen peroxide via two‐electron oxygen reduction; however, active site complexity continues to hinder reliable interpretation. This review critiques correlation‐based approaches and highlights the importance of orthogonal experimental designs, standardized catalyst passports ...

Second‐Generation Crystalline Sponges Enabling Consistent Structure Analysis Under Standardized Conditions for Diverse Molecules

Angewandte Chemie, EarlyView.
The second‐generation crystalline sponge method allows structurally diverse molecular guests to crystallize under standardized crystallization conditions. The key is the predominant packing type of cages and anions in crystals. ABSTRACT Crystallization is typically highly sensitive to even minor structural differences in target molecules.

A Homogeneously Catalyzed Paired Electrolytic Cell for Hydrogen Peroxide Production

Angewandte Chemie, EarlyView.
Cu(tmpa) and Sn‐TMPyP are compatible and efficient catalysts for 2e−‐ORR and 2e−‐WOR, respectively, which have been employed to assemble an efficient paired electrochemical cell for H2O2 production. The presence of a carbonate buffer is essential to achieve a high activity in the anode compartment, while control over mass transport is essential for a ...
