Yellow Powder | [Uses]
7,12-Dimethylbenz[a]anthracene was used:
- to study the effects of Cimicifuga racemosa (CR) extract on the growth of mammary tumor induced by 7,12-Dimethylbenz[a]anthracene
- in the study to compare the anti-carcinogenic properties of four red wine polyphenols as an initiator to cause skin cancer in CD-1 mouse model
- to induce epithelial carcinogenicity in order to study the apoptotic, proliferating and p12doc-1 profiles of normal, hyperplastic, dysplastic and malignant oral epithelium in the cheek pouch of the Syrian hamster
- to cause mammary tumors to examine the causes and prevention of triacylglycerol accumulation in rat liver due to tamoxifen
| [Uses]
A highly potent carcinogen that is activated by microsomal enzymes to a diol epoxide metabolite that binds covalently to DNA in mammalian cells, leading ultimately to tumor induction | [Definition]
ChEBI: A tetraphene having methyl substituents at the 7- and 12-positions. It is a potent carcinogen and is present in tobacco smoke. | [Synthesis Reference(s)]
The Journal of Organic Chemistry, 36, p. 966, 1971 DOI: 10.1021/jo00806a023 | [Biochem/physiol Actions]
7,12-Dimethylbenz[a]anthracene has been found to be cytotoxic in nature, having carcinogenic properties. It also shows selective necrosis and hemorrhaging in the adrenal gland along with an inhibitory effect on plasma alkaline phosphatase levels. Its damaging effects are due to its ability to form charge transfer complexes by donating electrons to appropriate electron acceptors. | [Potential Exposure]
Oxidizing agents | [First aid]
If this chemical gets into the eyes, remove anycontact lenses at once and irrigate immediately for at least15 min, occasionally lifting upper and lower lids. If thischemical contacts the skin, remove contaminated clothingand wash immediately with soap and water. If this chemicalhas been inhaled, remove from exposure, begin rescuebreathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if heart actionhas stopped. Transfer promptly to a medical facility | [storage]
Store at -20°C | [Shipping]
