The dissociation of nalidixic acid in the near neutral pH region is shown to be due to a single prototropic equilibrium involving the carboxyl group exclusively. Precise dissociation constants as well as stability constants for the binding of the nal

Oxidation of the anions of teniposide (I) and its aglycone (III) occurs over the pH range from 3 to 12 in two one-electron waves. The loss of the first electron yields a radical, the second a phenoxenium ion. The latter is converted by nucleophilic a

It has been suggested that etoposide can be transformed ‘in vivo’ into a radical intermediate, which may be involved in the irreversible binding of etoposide to microsomal proteins and in DNA damage. To investigate some physico-chemical propertie

The electrochemical oxidation of the antineoplastic agent etoposide in aqueous solution at a glassy carbon electrode shows an overall two electron transfer. At pH < 2.5, the oxidation proceeds in one voltammetric oxidation step. At pH ⩾ 2.5, the ox
