Selected hydrazines and related compounds were examined for their mutagenic activity in S. typhimurium strains TA1535 and TA1537. These in vitro assays were conducted with and without metabolic activation by Aroclor-induced rat-liver enzymes. Relatively high levels of mutagenicity were observed with phenylhydrazine · HCl, methylhydrazine, N′-acetyl-4-(hydroxymethyl)phenylhydrazine, and 4-(hydroxymethyl)benzenediazonium tetrafluoroborate, the stabilized salt of a carcinogenic metabolite of agaritine; only low levels of mutagenicity were observed with other compounds, although most are strong carcinogens. Several of the compounds were highly toxic to the bacteria, and detection of mutagenicity was enhanced by calculating the increase in mutagenic activity on the basis of the surviving fractions of bacteria.
