Description

General description

S-(5′-Adenosyl)-L-methionine p-toluenesulfonate salt is used for the treatment of depression, liver cirrhosis, cholestasis and degenerative joint disease.

Application

S-(5′-Adenosyl)-L-methionine p-toluenesulfonate salt has been used for cell proliferation assay. It has also been used for methylation assay.

Biochem/physiol Actions

Methyl donor; cofactor for enzyme-catalyzed methylations, including catechol O-methyltransferase (COMT) and DNA methyltransferases (DNMT). Although present in all cells, it is concentrated in liver where 85% of all methylation reactions occur. It is also involved in regulating liver function, growth, and response to injury.

S-(5′-Adenosyl)-L-methionine (SAM) is anti-apoptotic in normal hepatocytes and normal colon epithelial cells but pro-apoptotic in liver human hepatocellular carcinoma (HCC), HepG2 cells and colon cancer cells.

Caution

This material is unstable at room temperature.
