Description
Curator's Comment: description was created based on several sources, including https://www.ncbi.nlm.nih.gov/pubmed/17379181

Tenuazonic acid is one of the major Alternaria mycotoxins commonly found as a natural contaminant in food. Tenuazonic acid contamination has been linked to esophageal cancer in human populations at risk of high exposure. Tenuazonic acid inhibits protein synthesis by suppression at the ribosome. Tenuazonic acid was shown to inhibit 12-O-tetradecanoyl phorbol-13-acetate (TPA) induced ornithine decarboxylase (ODC) activity in a mouse model, and in turn suppressed mouse skin tumor promotion. In addition, this compound has been shown to be a new type of Photosystem II inhibitor.

Sample Use Guides

in mice: (skin carcinogenesis): Female Swiss albino mice were exposed topically to 100 nmole of 7,12-dimethyl benz(a) antracene (DMBA) twice weekly for 20 weeks. Another group of animals was treated with 250 microg tenuazonic acid (TA) in acetone daily for a period of 1 week, followed by the same dose of TA prior to every application of DMBA.
Route of Administration: Topical
In Vitro Use Guide
Curator's Comment: The results of competitive replacement with [(14)C]atrazine combined with JIP-test and D1-mutant showed that Tenuazonic acid (TeA) should be considered as a new type of photosystem II inhibitor because it has a different binding behavior within Q(B)-niche from other known photosystem II inhibitors.
