Immunochemical detection of a lipofuscin-like fluorophore derived from malondialdehyde and lysine

Journal of Lipid Research, 2001
The accumulation of fluorescent age pigment or lipofuscin is a frequently observed age-associated cellular alteration in a variety of postmitotic cells of many species. These pigments are observed within granules composed, in part, of damaged protein and

Electron Donor–Acceptor Complex Catalysis in Synthetic Chemistry

Angewandte Chemie, EarlyView.
Electron donor–acceptor (EDA) complexes are moving beyond stoichiometric photoactivation toward catalytic platforms for radical generation. Productive EDA catalysis requires coordinated donor–acceptor association, charge‐transfer excitation, radical reactivity, and vcatalyst turnover.
