5,6-Dihydrothymine

Dihydro-5-methyl-2,4(1H,3H)-pyrimidinedione

C5H8N2O2 (128.0585748)


Dihydrothymine (CAS: 696-04-8) is an intermediate breakdown product of thymine. Dihydropyrimidine dehydrogenase catalyzes the reduction of thymine into 5,6-dihydrothymine; then dihydropyrimidinase hydrolyzes 5,6-dihydrothymine into N-carbamyl-beta-alanine. Finally, beta-ureidopropionase catalyzes the conversion of N-carbamyl-beta-alanine into beta-alanine. When present at abnormally high levels, dihydrothymine can be toxic, although the mechanism of toxicity is not clear. In particular, patients with dihydropyrimidinase deficiency exhibit highly increased concentrations of 5,6-dihydrouracil and 5,6-dihydrothymine; and moderately increased concentrations of uracil and thymine can be detected in urine. Dihydropyrimidinase deficiency is a disorder that can cause neurological and gastrointestinal problems in some affected individuals. The most common neurological abnormalities that occur are intellectual disability, seizures, weak muscle tone (hypotonia), abnormally small head size (microcephaly), and autistic behaviours that affect communication and social interaction. Gastrointestinal problems that occur in dihydropyrimidinase deficiency include the backflow of acidic stomach contents into the esophagus (gastroesophageal reflux) and recurrent episodes of vomiting.

Pyroglutamine*

(3S)-3-Aminohexahydro-2,6-pyridinedione

C5H8N2O2 (128.0585748)


Pyroglutamine (CAS: 2353-44-8), also known as alpha-aminoglutarimide or 3-amino-1,6-dioxopiperidine, belongs to the class of organic compounds known as alpha amino acids and derivatives. These are amino acids in which the amino group is attached to the carbon atom immediately adjacent to the carboxylate group (alpha carbon), or a derivative thereof. Pyroglutamine is considered to be soluble (in water) and acidic. Pyroglutamine has been identified in the human placenta (PMID: 32033212).

Dihydro-5-methyl-2,4(1H,3H)-pyrimidinedione

C5H8N2O2 (128.0585748)


Dihydrothymine, also known as 5,6-dihydro-5-methyluracil or 5,6-dihydrothymine, (S)-isomer, is a member of the class of compounds known as hydropyrimidines. Hydropyrimidines are compounds containing a hydrogenated pyrimidine ring (i.e. containing less than the maximum number of double bonds.). Dihydrothymine is soluble (in water) and a very weakly acidic compound (based on its pKa). Dihydrothymine can be found in a number of food items such as hyssop, arrowroot, nopal, and red rice, which makes dihydrothymine a potential biomarker for the consumption of these food products. Dihydrothymine can be found primarily in blood, cerebrospinal fluid (CSF), saliva, and urine, as well as in human prostate tissue. Dihydrothymine exists in all living organisms, ranging from bacteria to humans. In humans, dihydrothymine is involved in the pyrimidine metabolism. Dihydrothymine is also involved in few metabolic disorders, which include beta ureidopropionase deficiency, dihydropyrimidinase deficiency, MNGIE (mitochondrial neurogastrointestinal encephalopathy), and UMP synthase deficiency (orotic aciduria). Moreover, dihydrothymine is found to be associated with beta-ureidopropionase deficiency and dihydropyrimidinase deficiency. Dihydrothymine is a non-carcinogenic (not listed by IARC) potentially toxic compound. Dihydrothymine is an intermediate in the metabolism of thymine . Dihydropyrimidine dehydrogenase catalyzes the reduction of thymine to 5, 6-dihydrothymine then dihydropyrimidinase hydrolyzes 5, 6-dihydrothymine to N-carbamyl-b-alanine. Finally, beta-ureidopropionase catalyzes the conversion of N-carbamyl-b-alanine to beta-alanine. Accumulation of dihydrothymine in the body has been shown to be toxic (T3DB).
