Several novel series of xanthine oxidase (XO) inhibitors (XOIs) with nitrogen-containing heterocycles have been reported recently. Our data indicate no correlation between these kinetic parameters and their one-electron reduction potentials, as would be expected if the enzyme were using two subsequent one-electron reduction steps. By invoking the existence of enzyme-xanthine complexes we can account for (a) the participation and time dependence of "very rapid" and "rapid" molybdenum and (b) the deuterium isotope effects observed during steady state ).
