  • Title: Genotoxic activity of m-nitrobenzaldehyde.
    Author: Sargent EV, Bradley MO.
    Journal: Mutat Res; 1986 Nov; 175(3):133-7. PubMed ID: 3534557.
    Abstract:
    m-Nitrobenzaldehyde (MNB) was evaluated for mutagenic activity using the Ames microbial mutagenicity test and for its ability to induce DNA single-strand breaks in rat hepatocytes as measured by alkaline elution. MNB was tested in S. typhimurium strains TA1535, TA1537, TA1538, TA98, and TA100, both with and without pretreatment with liver microsomes (S9) isolated from rats pretreated with Aroclor 1254. MNB produced 2-fold or greater increases in revertants in TA1538, both with and without S9, and in TA100 with S9 only. A 2-fold increase in revertants was seen in TA98, but only at the highest dose tested which did not produce inhibition of background growth. MNB caused a greater than 3-fold increase in elution slope, with DNA alkaline elution assay, but only at highly cytotoxic doses and, therefore, is not considered genotoxic in this system. It is concluded that MNB possesses weak genotoxic activity.
