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.

Packaging

25, 100, 500 mg in poly bottle

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.

Catechol-O-methyltransferase (COMT) is a major drug metabolizing enzyme in humans. COMT expression is directedly associated with various mental diseases and cancers due to its essential role in catalyzing metabolic inactivation of endogenous catecholamines and catechol estrogens. However, a practical method...
