Ptaquiloside in Bracken Spores From Britain

Chemosphere, 2013
Secondary metabolites from bracken fern (Pteridium aquilinum (L.) Kuhn) are suspected of causing cancer in humans. The main carcinogen is the highly water-soluble norsesquiterpene glucoside ptaquiloside, which may be ingested by humans through food, e.g. via contaminated water, meat or milk.

Purification of Ptaquiloside, a Carcinogen From Pteridium aquilinum

Phytochemistry, 1995
Ptaquiloside, the major carcinogen of bracken fern (Pteridium aquilinum), was isolated in high yield from milled freeze-dried plant material. Because the compound is unstable, a new method was devised to avoid steps which caused loss of activity. Modern multipulse and 2D NMR techniques allowed confirmation of the previously proposed structure, although

Ptaquiloside-Induced Early-Stage Urothelial Lesions Show Increased Cell Proliferation and Intact β-Catenin and E-Cadherin Expression

Environmental Toxicology, 2014
Bracken (Pteridium aquilinum) is a carcinogenic plant whose main toxin, ptaquiloside, causes cancer in farm and laboratory animals. Ptaquiloside contaminates underground waters as well as meat and milk from bracken-grazing animals and is a suspected ...

Multiple Genotoxic Activities of Ptaquiloside in Human Lymphocytes: Aneugenesis, Clastogenesis and Induction of Sister Chromatid Exchange

Mutation Research - Genetic Toxicology and Environmental Mutagenesis, 2012
Ptaquiloside, a norsesquiterpene glycoside from bracken (Pteridium aquilinum), is a known carcinogen towards animals. Its genotoxicity is mainly attributed to its DNA-alkylating and clastogenic properties.

Ptaquiloside From Bracken (Pteridium spp.) Inhibits Tumour-Infiltrating CD8+ T Cells in HPV-16 Transgenic Mice

Food and Chemical Toxicology, 2016
Bracken is a fern with worldwide distribution. Exposure to bracken toxins such as ptaquiloside is hypothesized to increase the risk of papillomavirus-related cancers of the upper digestive tract.
