Efficient Light‐Driven Multi‐Electron Accumulation on Viologens by Molecular Control Over Photochemical Reaction Pathways

open access: yesChemistry – A European Journal, EarlyView.
Minimum structural changes, maximum output: By either utilizing a more oxidizing Ru(II) polypyridyl chromophore or by using a more reducing SED, the photocatalytic reduction of methyl viologen (MV2+) proceeds via a reductive quenching pathway. This not only significantly accelerates the overall photoreduction process but also allows accumulation of ...

Targeting Cancer Cells With Self‐Assembled Ru‐Polysaccharide Photocatalyst for Visible‐Light‐Induced Activation of Prodrugs

open access: yesChemistry – A European Journal, EarlyView.
Self‐assembled photocatalyst Ru(Ada‐bpy)(bpy)2⊂HACD targets cancer cells and catalyzes the prodrug to drug upon exposure to visible light, providing spatially and temporally control in cancer cells. This strategy achieves efficient, controllable, and targeted activation of prodrugs within cancer cells, laying the foundation of effectively reducing the ...

Readily Accessible bTurea‐Derived Nitroxide Polarizing Agents for Dynamic Nuclear Polarization: bcTCOOKs and bcTmols

open access: yesChemistry – A European Journal, EarlyView.
Two families of bTurea‐derived biradicals, bcTmols and bcTCOOKs, were prepared as polarizing agents for dynamic nuclear polarization (DNP)‐enhanced NMR through short and efficient synthetic routes. The best‐performing biradical, bcTCOOK‐M2, containing two methyl groups on the urea bridge, provided signal enhancements of up to ∼220 at 14.1 T and 100 K ...

Trends and Future Directions in Organic Chemistry for Drug Discovery

open access: yesChemistry – A European Journal, EarlyView.
Organic synthesis is being reshaped by the convergence of catalytic innovation, automation, artificial intelligence, and emerging therapeutic modalities. Late‐stage functionalization, photoredox and electrochemical methods, biocatalysis, flow chemistry, DELs, and proximity‐based drugs are examined as components of closed‐loop discovery.

Asymmetric Activation of Tropos Biphenolic Moieties by Isohexides: An Integrated Computational‐Experimental Approach

open access: yesChemistry – A European Journal, EarlyView.
The integrated experimental‐computational study on the asymmetric activation exerted by isohexides on tropos tetra‐aryl moieties embedded in a chiral macrocyclic architecture resulted in a complete definition of the stereochemical as well as stereodynamic features of the macrocyclic final compounds.
