/GENOTOXICITY/ The mutagenicity of 4-nitro-m-phenylenediamine in DMSO in Salmonella typhimurium strains TA97, TA98, TA100, TA1535, and TA1537 was evaluated with and without metabolic activation ... The test substance (0.0-10,000 ug/plate) was incubated with each Salmonella culture for 20 min (37 °C) prior to plating. Two different S-9 mixes (rat and hamster liver) were used. ... 4-Nitro-m-phenylenediamine was mutagenic in strain TA98 both with and without metabolic activation, but was not mutagenic in strains TA100 and TA1535. In strain TA1537, positive (S-9 mix, hamster liver) and negative (S-9 mix, rat liver) results were obtained with metabolic activation, and, negative results, without metabolic activation. In strain TA97, 4-nitro-m-phenylenediamine was mutagenic only in the presence of metabolic activation (10.0% S-9, hamster liver). ... 4-nitro-m-phenylenediamine was mutagenic.
/OTHER TOXICITY INFORMATION/ ... Review of the 4-nitro-1,3 -Benzenediamine toxicological properties revealed a median lethal dose of 500 mg/kg in an acute oral toxicity study in mice. /This coumpound/ was mutagenic in the Ames/Salmonella assay and a chromosome aberrations test. Equivocal results were demonstrated in a sister chromatid exchange assay. No carcinogenicity data existed. ... no data on the skin irritation and sensitization and dermal toxicity potential ...

reported nonpeptidic angiotensin II (AII) receptor antagonists DuP753 (1) and Exp 7711 (2), we have designed and investigated novel substituted benzimidazoles. Systemic variation of several substituents at the benzimidazole ring positions 4-7 led to the finding that substitution in position 6 with acylamino groups results in highly active AII antagonists. Compounds with 6-membered lactam or sultam substituents
