Conventional tests for polymerization initiated by free radicals indicate that alkylating agents vary in free radical inhibitory activity from negligible to moderately strong; antimetabolites from negligible to weak; hormones, steroids, and phenolics from very weak to very strong; and antibiotics from moderate to very strong. Vitamins A and C and copper, which potentiate the biological activity of some anticancer compounds, are relatively strong free radical inhibitors.
