Description générale

7,12-Dimethylbenz[a]anthracene belongs to the category of polycyclic aromatic hydrocarbons.[1] It is a carcinogenic organic pollutant generated from the incomplete combustion of gasoline and coal.[2]

Application

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[3]
  • 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[4]
  • 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[5]
  • to cause mammary tumors to examine the causes and prevention of triacylglycerol accumulation in rat liver due to tamoxifen[6]

Actions biochimiques/physiologiques

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.[5][1]

Carcinogenesis and Epigenetics

Cancer research has revealed that the classical model of carcinogenesis, a three step process consisting of initiation, promotion, and progression, is not complete.

Questions

1–2 of 2 Questions  

  1. How can I determine the shelf life / expiration / retest date of this product?

    1 answer

    1. If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
      For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
      For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.

  2. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 answer

    1. Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf
