Function of Ademetionine 1,4-butanedisulfonate
Ademetionine 1,4-butanedisulfonate (SAM / SAMe) is a physiologically active molecule commonly found in human tissues and body fluids. It acts as a methyl donor (transmethylation) and a precursor of physiological sulfhydryl compounds (such as cysteine, taurine, glutathione, coenzyme A, etc.) (transsulfation) , participates important functions of biochemical reaction in the body.
The multiple mechanisms of adenosylmethionine are mainly reflected in the following aspects:
1. Transmethylation: Improve liver cell membrane fluidity, enhance Na+-K+-ATPase activity, promote bile secretion and operation, and participate in neurotransmitter synthesis, which can improve patient mood.
2. Transsulfide group: generate endogenous antidote, such as cysteine, glutathione, taurine, etc., play detoxification and antioxidant effects, and reduce liver cell damage.
3. Transformation of propylamino group: Synthesize biological polyamines, participate in metabolism in the body, regulate the regeneration and proliferation of liver cells, and accelerate the repair of liver function.
Indication of Ademetionine 1,4-butanedisulfonate:
Suitable for intrahepatic cholestasis before and after cirrhosis.
Suitable for intrahepatic cholestasis during pregnancy. |

Functions of Ademetionine 1,4-Butanedisulfonate
Ademetionine 1,4-butanedisulfonate (SAMe-1,4-BDS) is a stable salt form of S-adenosylmethionine (SAMe), a naturally occurring compound in the human body. Its primary functions include:
1. Liver Health:Promotes hepatocyte regeneration and detoxification. Used to treat liver disorders (e.g., cirrhosis, hepatitis, cholestasis) by enhancing glutathione synthesis and reducing oxidative stress.
2. Neurological and Psychiatric Applications: Modulates neurotransmitter synthesis (e.g., serotonin, dopamine), supporting the treatment of depression, anxiety, and cognitive disorders.
3. Joint Health: Stimulates proteoglycan synthesis in cartilage, aiding in osteoarthritis management.
4. Enhanced Stability: The 1,4-butanedisulfonate salt improves SAMe’s stability and bioavailability, ensuring longer shelf life and better therapeutic efficacy compared to free SAMe.
China holds significant competitive advantages in producing SAMe-1,4-butanedisulfonate:
1. Scalable Production: Large-scale fermentation and chemical synthesis facilities support high-volume output to meet global demand.
2. Advanced Technology: Adoption of cutting-edge biotechnological processes (e.g., microbial fermentation, enzymatic conversion) ensures high-purity SAMe synthesis.
3. Supply Chain Integration: Well-established raw material networks (e.g., methionine, ATP precursors) reduce lead times and production costs.
Customization Capabilities: Flexibility to produce tailored formulations (e.g., injectables, oral tablets) for diverse clinical needs.
