Metabolite Identification

Common Name

N-Methylhydantoin

Description

N-methylhydantoin is a imidazolidine-2,4-dione that is the N-methyl-derivative of hydantoin. It has a role as a bacterial metabolite. It derives from a hydantoin. N-Methylhydantoin is a small molecular weight polar substance, the product of degradation of creatinine by bacteria (hydrolyzed by creatinine iminohydrolase, EC 3.5.4.21 to ammonia and N-methylhydantoin). In mammals, the metabolism of 1-methylhydantoin occurs via 5-hydroxy-1-methylhydantoin. In a reported human case, 1-Methylhydantoin was found as an unexpected metabolite of the intelligence-affecting substance dupracetam (PMID:15533691 , 8287520 , 3196760 , 7294979 ).
