Cocarcinogenic activity of peroxy compounds

F G Bock, H K Myers, H W Fox

    Journal of the National Cancer Institute
    |December 1, 1975
    PubMed
    Summary

    Peracetic acid acts as a potent tumor promoter and weak carcinogen in mice skin. Decomposed peracetic acid and other peroxides showed no tumor-promoting activity, indicating specific chemical structures are key.

    Area of Science:

    • Toxicology
    • Carcinogenesis
    • Dermatology

    Background:

    • Peracetic acid is a widely used disinfectant with potential toxicological implications.
    • Understanding the carcinogenic potential of peracetic acid and its derivatives is crucial for risk assessment.

    Purpose of the Study:

    • To evaluate the tumor-promoting and carcinogenic activity of peracetic acid on mouse skin.
    • To compare the activity of peracetic acid with its decomposition products and related compounds.

    Main Methods:

    • Topical application of peracetic acid and other chemicals to the skin of female ICR Swiss mice.
    • Assessment of tumor promotion and carcinogenicity following chemical exposure.

    Main Results:

    • Peracetic acid demonstrated potent tumor-promoting and weak complete carcinogenic activity.
    • Decomposed peracetic acid was inactive as a tumor promoter.
    • Urea peroxide (3% and 5%) was inactive, while perbenzoic acid (1%) and m-chloroperbenzoic acid were active tumor promoters.

    Conclusions:

    • Peracetic acid exhibits significant tumor-promoting and weak carcinogenic effects on mouse skin.
    • The chemical structure and stability of peroxy compounds influence their carcinogenic potential.
    • Further research is warranted to elucidate the mechanisms underlying the observed activities.
