    Description: Precocene II , an insect growth regulator, it inhibits the production of juvenile hormone (JH) in insects, it is highly toxic to adult female Rhodnius and treatment of newly emerged females prevented oogenesis. Precocene II is structurally related to several naturally occurring carcinogenic and non-carcinogenic alkenylbenzenes, is genotoxic and produces hepatic centrolobular necrosis in rats.
    Targets: Antifection
    In vivo:
    Chem Biol Interact. 1989;71(2-3):187-99.
    Alteration of precocene II-induced hepatotoxicity by modulation of hepatic glutathione levels.[Pubmed: 2598296]
    Precocene II (6,7-dimethoxy-2,2-dimethyl-2H-benzo[b]pyran), an insect growth regulator that is structurally related to several naturally occurring carcinogenic and non-carcinogenic alkenylbenzenes, is genotoxic and produces hepatic centrolobular necrosis in rats. This investigation was conducted to evaluate the effects of modulation of hepatic glutathione levels on the toxicity of Precocene II.
    METHODS AND RESULTS:
    Administration of a toxic dose of Precocene II (175 mg/kg) to male Sprague-Dawley rats rapidly depleted hepatic GSH, produced histopathological changes in the liver, and induced increases in serum aminotransferase activity. Concurrent administration of the cysteine pro-drug L-2-oxothiazolidine-4-carboxylic acid (OTC) prevented these toxic effects of Precocene II. In contrast, pretreatment of rats with DL-buthionine-SR-sulfoximine (BSO), an inhibitor of glutathione synthesis, potentiated the toxicity of an otherwise non-toxic dose of Precocene II (100 mg/kg).
    CONCLUSIONS:
    These results indicate that glutathione is important for protection from Precocene II-induced hepatotoxicity.
