Synthesis and Biological Studies of Iodinated (127/125I) Derivatives of Rhodamine 123
Rhodamine 123, a mitochondrial stain that preferentially accumulates in certain cancer cells, has been reduced and iodinated by using NaI in the presence of N-chlorosuccinimide.The various mono-, di-, and triiodo derivatives have been isolated and charact

A significant improvement of the efficacy of radical oxidant probes by the kinetic isotope effect
A breath of fresh air: The rate of aerial oxidation of dihydroethidium and hydrocyanine radical oxidant probes can be selectively reduced by deuteration (see picture). The reaction rate between the deuterated compounds and the superoxide radical was reduced by a much smaller factor because of mechanistic differences between the two reactions.
