title: EPR study of anion radicals of various N-quinonyl amino acids.
abstract: Since peptide quinones possess great clinical potential in targeted chemotherapy, several series of novel N-quinonyl amino acids have been synthesized and their first products of reduction were studied by EPR spectroscopy. EPR spectra of the corresponding radical adducts were identified by computer simulation. The dependence between the splitting constants and the chemical structure of the N-quinonyl amino acids anion radicals was examined.
