Molecules that bind and illuminate proteins specific to tumor cells are key to detecting cancer as early as possible. The cyclooxygenase-2 (COX-2) enzyme is just such a protein, as the concentration of COX-2 is greater in cancer cells than in adjacent normal tissues.
Therefore, attaching a suitable fluorescent label to a selective COX-2 inhibitor would be an effective strategy for the noninvasive detection of tumors in which COX-2 levels are elevated.
As they report in ChemMedChem, a collaboration led by Frank Wuest, Edward Knaus, and colleagues at the University of Alberta in Canada resulted in an important compound in which a 7-nitrobenzofurazan (NBD) fluorescent label is linked to the well-known anti-inflammatory drug celecoxib (celecoxib–NBD conjugate).

Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
