Repositioning Candidate Details

Candidate ID: R0016
Source ID: DB00134
Source Type: approved; nutraceutical
Compound Type: small molecule
Compound Name: Methionine
Synonyms:
Molecular Formula: C5H11NO2S
SMILES: CSCC[C@H](N)C(O)=O
Structure:
DrugBank Description: A sulfur containing essential amino acid that is important in many body functions. It is a chelating agent for heavy metals.
CAS Number: 63-68-3
Molecular Weight: 149.211
DrugBank Indication: Used for protein synthesis including the formation of SAMe, L-homocysteine, L-cysteine, taurine, and sulfate.
DrugBank Pharmacology: L-Methionine is a principle supplier of sulfur which prevents disorders of the hair, skin and nails; helps lower cholesterol levels by increasing the liver's production of lecithin; reduces liver fat and protects the kidneys; a natural chelating agent for heavy metals; regulates the formation of ammonia and creates ammonia-free urine which reduces bladder irritation; influences hair follicles and promotes hair growth. L-methionine may protect against the toxic effects of hepatotoxins, such as acetaminophen. Methionine may have antioxidant activity.
DrugBank MoA: The mechanism of the possible anti-hepatotoxic activity of L-methionine is not entirely clear. It is thought that metabolism of high doses of acetaminophen in the liver lead to decreased levels of hepatic glutathione and increased oxidative stress. L-methionine is a precursor to L-cysteine. L-cysteine itself may have antioxidant activity. L-cysteine is also a precursor to the antioxidant glutathione. Antioxidant activity of L-methionine and metabolites of L-methionine appear to account for its possible anti-hepatotoxic activity. Recent research suggests that methionine itself has free-radical scavenging activity by virtue of its sulfur, as well as its chelating ability.
Targets: Methionine synthase reductase; Methionine synthase; Methionine aminopeptidase 2; Betaine--homocysteine S-methyltransferase 1; S-methylmethionine--homocysteine S-methyltransferase BHMT2
