Biological Activity

Description	Ademetionine (AdoMet, S-Adenosylmethionine, SAMe), also known as SAMe, is a specific form of the amino acid methionine known as S-adenosyl-methionine. It is essential for the formation of glutathione, a water-soluble peptide that helps the body fight free radicals.

In vitro
In vitro	Ademetionine (S-adenosylmethionine; SAMe) 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^[1].

In Vivo
In vivo	SAMe is able to cross the intestinal wall and increase plasma levels. Studies in rats reveal that absorption of the drug is much better after intraduodenal administration compared to oral administration. The systemic bioavailability after oral SAMe administration appears to be low. SAMe dose-dependently (12.5, 25, 50, 100 and 200 mg/kg sc.) decreases immobility time in the forced swimming test in mice and rats. Chronic treatment with SAMe is associated with an increase in density of b-receptors, and a decrease in the affinity of a1 adrenoceptors for phenylephrine in rat cerebral membranes^[1].

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH₂O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
