The electroconvulsive threshold is markedly elevated by scosine (400–800 mg/kg; ip) [2].

Animal/Disease Models: Albino Swiss mouse body weight (25-30 g)[2]
Doses: 100 mg/kg, 200 mg/kg, 400 mg/kg, 800 mg/kg
Route of Administration: intraperitoneal (ip) injection
Experimental Results: in mice MEST In trials, epilepsy thresholds were elevated at doses of 400 mg/kg and 800 mg/kg.

Metabolism / Metabolites
Sarcosine is metabolized to glycine by the enzyme sarcosine dehydrogenase, while glycine-N-methyl transferase generates sarcosine from glycine.

Toxicity Summary
Sarcosine is an oncometabolite. Sarcosine appears to upregulate the expression of the potent oncoprotein called human epidermal growth factor receptor 2 (HER2/neu) in androgen-dependent prostate cancer cells upon exposure to exogenous sarcosine. Thus, sarcosine may induce prostate cancer progression by increased HER2/neu expression.

Deliquescent crystals or powder. Has a sweetish taste. (NTP, 1992)
Sarcosine is a N-alkylglycine that is the N-methyl derivative of glycine. It is an intermediate in the metabolic pathway of glycine. It has a role as a glycine transporter 1 inhibitor, a glycine receptor agonist, a human metabolite, an Escherichia coli metabolite and a mouse metabolite. It is a N-alkylglycine, a N-methyl-amino acid and a member of N-methylglycines. It is a conjugate base of a sarcosinium. It is a conjugate acid of a sarcosinate. It is a tautomer of a sarcosine zwitterion.
Sarcosine has been investigated for the treatment of Schizophrenia.
Sarcosine is a metabolite found in or produced by Escherichia coli (strain K12, MG1655).
Sarcosine has been reported in Sarcococca saligna, Drosophila melanogaster, and other organisms with data available.
Sarcosine is an amino acid that is an intermediate and byproduct in glycine synthesis and degradation with potential anti-depressant and anti-schizophrenic activities. Sarcosine is a product of dietary consumption of choline and creatine and is rapidly converted into glycine. Oral administration of sarcosine with certain antipsychotics may cause increased glycine concentration in the brain, which may lead to increased NMDA receptor activation and a reduction in symptoms.
Sarcosine is the N-methyl derivative of glycine. Sarcosine is metabolized to glycine by the enzyme sarcosine dehydrogenase, while glycine-N-methyl transferase generates sarcosine from glycine. Sarcosine is a natural amino acid found in muscles and other body tissues. In the laboratory it may be synthesized from chloroacetic acid and methylamine. Sarcosine is naturally found in the metabolism of choline to glycine. Sarcosine is sweet to the taste and dissolves in water. It is used in manufacturing biodegradable surfactants and toothpastes as well as in other applications. Sarcosine is ubiquitous in biological materials and is present in such foods as egg yolks, turkey, ham, vegetables, legumes, etc. Sarcosine is formed from dietary intake of choline and from the metabolism of methionine, and is rapidly degraded to glycine. Sarcosine has no known toxicity, as evidenced by the lack of phenotypic manifestations of sarcosinemia, an inborn error of sarcosine metabolism. Sarcosinemia can result from severe folate deficiency because of the folate requirement for the conversion of sarcosine to glycine (Wikipedia). Sarcosine has recently been identified as a biomarker for invasive prostate cancer. It was found to be greatly increased during prostate cancer progression to metastasis and could be detected in urine. Sarcosine levels were also increased in invasive prostate cancer cell lines relative to benign prostate epithelial cells (A3519).
An amino acid intermediate in the metabolism of choline.
