tumor-bearing mice. Among the most active agents were the mesylates, tosylates, and N-(chloroethyl)carbamates of 2- and 6-methyl-1,4-naphthoquinone. That bioreductive activation to a quinone methide might be involved in the mechanism of action of these agents was shown by the finding that compounds with the best leaving groups were the most efficacious as antineoplastic agents.
