Could Polyphenols Help in the Control of Rheumatoid Arthritis?
Molecules, 2019 Rheumatoid arthritis (RA) is a chronic, systemic, joint-invading, autoimmune inflammatory disease, which causes joint cartilage breakdown and bone damage, resulting in functional impairment and deformation of the joints. The percentage of RA patients has

Molecules, 2011 The n-butyramido, isobutyramido, benzamido, and furancarboxamido functions profoundly modulate the electronics of the stilbene olefinic and NH groups and the corresponding radical cations in ways that influence the efficiency of the cyclization due ...

Mechanically Interlocked Indigo Photoswitches
Angewandte Chemie, EarlyView.By incorporating indigo photoswitches into the axle of a rotaxane, which features a hydrogen bonding macrocycle, we demonstrate improvement in activation wavelength, photostationary states and thermal reversion, an effect that is governed by topologically constrained supramolecular interactions.

Angewandte Chemie, EarlyView.We address the long‐standing challenge of reactivity–selectivity trade‐off by precisely tuning the redox properties of Fe(IV), rather than simply accelerating its formation, to enable chemically efficient and low‐emission water treatment. ABSTRACT High‐valent iron oxo species (Fe(IV)) are attractive for wastewater treatment because of their high ...

From Stilbenes to carbo‐Stilbenes: an Encouraging Prospect
Chemistry – A European JournalAbstractBeyond previously described carbo‐naphthalene and carbo‐biphenyl, a novel type of bis‐carbo‐benzenic molecules is envisaged from the stilbene parent. The synthesis, structure, spectroscopic and electrochemical properties of two such carbo‐stilbenes are described at complementary experimental and computational DFT levels. In the selected targets,

T‐Shaped Stibenium(III) Cation: Hydrostibination Without Sb─H Bond
Angewandte Chemie, EarlyView.A cationic, structurally constrained stibenium platform mediates anti‐Markovnikov hydrostibination of alkenes via element–ligand cooperativity (ELC), thereby bypassing the need for weak Sb─H bonds. ABSTRACT The hydrostibination of alkenes represents a largely underdeveloped transformation, owing to the intrinsic lability of the required Sb─H reagents ...

Angewandte Chemie, EarlyView.Protic molecules containing strong O─H or N─H bonds typically resist hydrogen‐atom abstraction because of the high reactivity of the resulting heteroatom‐centered radicals. However, association of the protic molecules with redox‐active Lewis acids can provide powerful hydrogen‐atom donors or proton‐coupled‐electron‐transfer reagents.

From Berzelius to Hyperspace: Previously Unrecognized Network of Reactivity in Textbook Brominations
Angewandte Chemie, EarlyView.Robotic scans across multidimensional condition spaces of classic bromination reactions uncover regions of previously unrecognized reactivity, yielding new major products and novel substitution patterns. Correlation and anticorrelation analyses of product distributions across these hyperspaces enable reconstruction of the underlying mechanistic ...
