Description: Ademetionine, also known as AdoMet; MSI-195; SAMe, S-adenosylmethionine, is a PDE4B inhibitor potentially for treatment of primary biliary cirrhosis and major depressive disorder. Ademetionine is a ubiquitous metabolite present in all cells and biological fluids, and serves as a methyl donor in a multitude of different methylation reactions involving proteins, phospholipids, catecholamines and DNA. Pharmaceutical preparations of some stable salts of SAMe are available for parenteral and oral use in humans, and have been shown to increase plasma and cerebrospinal fluid SAMe concentrations.

Synonym: Ademetionine; AdoMet; MSI-195; MSI 195; MSI195; SAMe; S-adenosylmethionine. Heptral; Gumbaral.
