Copper(II), in the parts per million range, modulates photochemical and photosensitizing properties of tolmetin via electron transfer with a triplet carbanion
Abstract
Copper(II), at very low levels of concentration, modulates the distribution of tolmetin stable photoproducts as well as inhibits the DNA cleavage photoinduced by the drug, via a highly efficient electron transfer process with the main transient species generated in the tolmetin photolysis.
