Diruthenium tetracarbonyl complexes of the type [Ru2 (CO)4(μ2-η2-O2CR)2L2] containing a Ru–Ru backbone with four equatorial carbonyl ligands, two carboxylato bridges, and two axial two-electron ligands in a sawhorse-like geometry have been synthesized with porphyrin-derived substituents in the axial ligands...

Determination of Intracellular Prolyl/Glycyl Proteases in Intact Living Human Cells and Protoporphyrin IX Production as a Reporter System

Berger, Yann ; Chapuis Bernasconi, Catherine ; Schmitt, Frédéric ; Neier, Reinhard ; Juillerat-Jeanneret, Lucienne

In: Chemistry & Biology, 2005, vol. 12, no. 8, p. 867-872

The determination of enzyme activity or inhibition in intact living cells is a problem in the development of inhibitors for intracellular proteases. The production of fluorescent protoporphyrin IX (PpIX) from the nonfluorescent (N)-Gly/Pro-5-aminolevulinic acid (ALA) substrates was used to evaluate the prolyl/glycyl-specific dipeptidylpeptidase IV (DPPIV)-like and prolyloligopeptidase (POP)-like...

Mononuclear 5-(4-pyridyl)-10,15,20-triphenylporphyrin and 5-(3-pyridyl)-10,15,20-triphenylporphyrin as well as tetranuclear 5,10,15,20-tetra(4-pyridyl)porphyrin (tetra-4-pp) and 5,10,15,20-tetra(3-pyridyl)porphyrin) (tetra-3-pp) arene ruthenium(II) derivatives (arene is C6H5Me or p-PriC6H4Me) were prepared and evaluated as potential...
