Acrylonitrile (AN) and methacrylonitrile (MAN) are two major industrial nitriles used in the production of plastics and acrylic fibers. Whereas AN is a potent acute toxin and carcinogenic in rats, little is known regarding MAN. Current work is part o

1-bromopropane (1-BrP) induces dose- and time-dependent reproductive organ toxicity and reduced sperm motility in rodents. The contribution of cytochrome P4502E1 (CYP2E1) to both 1-BrP metabolism and the induction of male reproductive toxicity was in

Methacrylonitrile (MAN) is a widely used aliphatic nitrile and is structurally similar to the known rat carcinogen and suspected human carcinogen acrylonitrile (AN). There is evidence that AN is metabolized via the cytochrome P-450 (CYP) 2E1. Recentl

Surprisingly, disruption of the COX-1 gene resulted in generally healthy mice. This is in spite of the fact that prostaglandin levels in the tissues examined were reduced by greater than 99%. The results obtained to date with the COX-1 deficient mice

Nalidixic acid (NA) is an antimicrobial drug that has been used to treat urinary tract infections. A study of NA by the National Toxicology Program indicated that chronic administration in the diet at doses equivalent to 82 and 175 mg/kg/day for rats

Omeprazole (OP) is a potent antiulcer drug that is metabolized by liver cytochrome P450 (P450) enzymes. However, the identities of the P450 isoforms responsible for its metabolism have been controversial. 5-Hydroxyomeprazole (5OH-OP) formation cosegr

Methacrylonitrile (MAN) is structurally similar to the known carcinogen acrylonitrile (AN), has similar industrial uses, and is occasionally used as its replacement. In contrast to AN, minimal information is available on the toxicity, carcinogenicity

Methacrylonitrile (MAN) is an industrial chemical used to manufacture plastics and elastomers. The reported p.o. LD50 of MAN is 200 to 230 mg/kg in rats and 17 mg/kg in mice. Present investigations were undertaken to further characterize MAN metaboli

[14C]1,2-Bis(2,4,6-tribromophenoxy)ethane (FF-680) was administered at 0.05, 0.5, or 5% in the diet for 1 day to three groups (four rats per group) of rats, and daily at 0.05% in the diet for 10 days to another group of five rats. In addition, anothe

Methacrylonitrile (MAN), an aliphatic nitrile used in the production of plastics and elastomers, is structurally related to the known animal carcinogen, acrylonitrile. Although MAN has potential to cause significant toxicity, minimal information is a
