Autor: I. B. Mahadevan, Edward R. T. Tiekink, and A. David Ward, Marc C. Kimber, Stephen F. Lincoln
Publikováno v: The Journal of Organic Chemistry. 65:8204-8209
The synthesis and fluorescent properties in the absence and presence of zinc(II) of a range of 2-substituted derivatives of N-(6-methoxy-2-methyl-8-quinolyl)-4-methylbenzenesulfonamide are described. These analogues formed complexes with zinc(II) as

Video image analysis of labile zinc in viable pancreatic islet cells using a specific fluorescent probe for zinc
Autor: W. H. Betts, A. Slavotinek, Ian J. Forbes, S. H. Millard, Peter D. Zalewski, O. Kapaniris, A. D. Ward, Stephen F. Lincoln, I. B. Mahadevan
Publikováno v: Journal of Histochemistry & Cytochemistry. 42:877-884
We used an intracellular zinc-specific fluorophore, Zinquin, in conjunction with fluorescence video image analysis, to reveal labile zinc in pancreatic islet cells, which concentrate this metal for use in synthesis, storage, and secretion of insulin.

Convergent proton-transfer photocycles violate mirror-image symmetry in a key melanin monomer
Autor: I. B. Mahadevan, Ross H. McKenzie, Sean C. Smith, Jennifer Riesz, Seth Olsen, Aaron J. Coutts, Paul Meredith, Benjamin J. Powell, Jacques P. Bothma
Publikováno v: Journal of the American Chemical Society. 129(21)
We present absorption and emission spectra of 5,6-dihydroxyindole-2-carboxylic acid (DHICA), a key melanin monomer, which violate mirror symmetry, and propose that this violation is due to convergent excited-state intramolecular proton-transfer photo
