  • Title: Protective effects of 4-nerolidylcatechol against genotoxicity induced by cyclophosphamide.
    Author: Valadares MC, Rezende KR, Pereira ER, Sousa MC, Gonçalves B, de Assis JC, Kato MJ.
    Journal: Food Chem Toxicol; 2007 Oct; 45(10):1975-8. PubMed ID: 17574317.
    Abstract:
    In the present work we evaluated both the mutagenicity and antimutagenicity of the Pothomorphe umbellata root extract (PUE) and its isolated active principle, the 4-nerolidylcatechol (4-NC), in bone marrow cells of mice using the micronucleus test. Swiss male mice were orally treated for 4 days with PUE (200, 100 or 50mg/kg/day) or 4-NC (50, 25 or 12.5mg/kg/day) prior to exposition with a single dose (200mg/kg) of cyclophosphamide (CP), 24h after the end of the treatment. The results demonstrated that the PUE and 4-NC did not have any mutagenic effect on mouse bone marrow cells; quite the opposite, there was a protective effect against genotoxicity induced by cyclophosphamide. Taken together, under the conditions tested herein, mice treated with PUE and 4-NC showed, in a dose-dependent manner, protective effect against CP-induced genotoxicity. Due to their ability to prevent chromosomal damage, with apparent low toxicity and cost, PUE or pure 4-NC are likely to open a field of interest concerning their possible use in clinical applications.
