Square wave voltammetry has been used to study the electrochemical behaviou
r of anti-HIV drugs in aqueous solutions. The oxidation reaction of Carbovi
r (1) at a Pt microelectrode occurs at 1.12 V versus SCE and the peak curre
nt is proportional to the concentration. An electroanalytical technique for
the determination of trace concentrations of Carbovir (1) is proposed and
experimental conditions have been optimised. The effect of Cu(II) on the el
ectrochemistry of nucleosides and nucleotides has also been studied. An equ
ilibrium between the nucleotide-copper complex formed and the free nucleoti
de is observed. (C) 2000 Elsevier Science S.A. All rights reserved.
