to determine whether it is possible to separate antitumour and mutagenic properties in the nitracrine series , a number of 4-substituted derivatives of the hypoxia-selective drug nitracrine have been evaluated for their mutagenic effects at three loci in several strains of salmonella typhimurium differing in dna-repair capacity ( uvrb , reca , plasmid pkm101 ) .
