certain prokaryotic RNA polymerases. It has been proposed that the antitumour activity of Rifamycin SV is due to its ability to chelate metal ions in solution, thus decreasing their availability to act as coenzymes for RNA polymerase. In this report, a two-step approach based on free-radical generation and metal complexation in solution was followed by e.s.r. spectroscopy. The e.s.r. measurements and
