Pyroglutamic acid

(S)-(-)-gamma-Butyrolactam-gamma-carboxylic acid

C5H7NO3 (129.0425912)


Pyroglutamic acid (5-oxoproline) is a cyclized derivative of L-glutamic acid. It is an uncommon amino acid derivative in which the free amino group of glutamic acid cyclizes to form a lactam. It is formed nonenzymatically from glutamate, glutamine, and gamma-glutamylated peptides, but it can also be produced by the action of gamma-glutamylcyclotransferase on an L-amino acid. Elevated blood levels may be associated with problems of glutamine or glutathione metabolism. This compound is found in substantial amounts in brain tissue and other tissues in bound form, especially skin. It is also present in plant tissues. It is sold, over the counter, as a "smart drug" for improving blood circulation in the brain. Pyroglutamate in the urine is a biomarker for the consumption of cheese. When present in sufficiently high levels, pyroglutamic acid can act as an acidogen and a metabotoxin. An acidogen is an acidic compound that induces acidosis, which has multiple adverse effects on many organ systems. A metabotoxin is an endogenously produced metabolite that causes adverse health effects at chronically high levels. Chronically high levels of pyroglutamic acid are associated with at least five inborn errors of metabolism including 5-oxoprolinuria, 5-oxoprolinase deficiency, glutathione synthetase deficiency, hawkinsinuria, and propionic acidemia. Pyroglutamic acid is an organic acid. Abnormally high levels of organic acids in the blood (organic acidemia), urine (organic aciduria), the brain, and other tissues lead to general metabolic acidosis. Acidosis typically occurs when arterial pH falls below 7.35. In infants with acidosis, the initial symptoms include poor feeding, vomiting, loss of appetite, weak muscle tone (hypotonia), and lack of energy (lethargy). These can progress to heart, liver, and kidney abnormalities, seizures, coma, and possibly death. These are also the characteristic symptoms of the untreated IEMs mentioned above. Many affected children with organic acidemias experience intellectual disability or delayed development. In adults, acidosis or acidemia is characterized by headaches, confusion, feeling tired, tremors, sleepiness, and seizures. It has been shown that pyroglutamic acid releases GABA from the cerebral cortex and displays anti-anxiety effects in a simple approach-avoidance conflict situation in the rat. In clinical pharmacology experiments, pyroglutamic acid significantly shortens the plasma half-life of ethanol during acute intoxication. Found in vegetables, fruits and molasses. A cyclized derivative of L-glutamic acid. It is an uncommon amino acid derivative in which the free amino group of glutamic acid cyclizes to form a lactam.

Pyrroline hydroxycarboxylic acid

3-Hydroxy delta 1-pyrroline-5-carboxylic acid, anion

C5H7NO3 (129.0425912)


Pyrroline hydroxycarboxylic acid is a metabolite identified in the urine of patients with type II hyperprolinemia. (OMIM 239510). The urinary excretion of Pyrroline hydroxycarboxylic acid increased in hyperprolinemic patients but not in healthy controls during oral loading of hydroxyproline and hydroxyproline-ornithine. (PMID: 533224). Hyperprolinemia type II (HP II) is a rare inherited metabolic disease due to the deficiency of pyroline-5-carboxylate dehydrogenase. It is generally believed to be a benign condition although some patients have neurological problems such as refractory convulsions. (PMID: 15214748). The oxidation of pyrroline-carboxylate generates glutamate and pyrroline-hydroxycarboxylate, a reaction catalyzed by hydroxyproline oxidase (PMID: 500817). Pyrroline hydroxycarboxylic acid is a metabolite identified in the urine of patients with type II hyperprolinemia. (OMIM 239510)

   

1-Pyrroline-4-hydroxy-2-carboxylate

4-hydroxy-4,5-dihydro-3H-pyrrole-2-carboxylic acid

C5H7NO3 (129.0425912)


Much or all of the pyrrole-2-carboxylate (PCA) in human urine may be formed in urine from a labile precursor, presumably delta(1)-pyrroline-4-hydroxy-2-carboxylate. Normal human values for endogenous urinary PCA in 16 individuals averaged 0.51 mumol/day, with a range of 0.20-1.3 mumol and a SD of 0.31 mumol. The probable source of human PCA is free hydroxy-L-proline, as inferred from the high value for PCA in the urine of a subject with hereditary hydroxyprolinemia, and from the threeto eightfold elevation in PCA excretion by two normal subjects after a large oral load of hydroxyl-L-proline. (PMID: 4430715). Much or all of the pyrrole-2-carboxylate (PCA) in human urine may be formed in urine from a labile precursor, presumably delta(1)-pyrroline-4-hydroxy-2-carboxylate.

Flucytosine

6-amino-5-fluoro-1,2-dihydropyrimidin-2-one

C4H4FN3O (129.0338386)


Flucytosine is only found in individuals that have used or taken this drug. It is a fluorinated cytosine analog that is used as an antifungal agent. [PubChem]Although the exact mode of action is unknown, it has been proposed that flucytosine acts directly on fungal organisms by competitive inhibition of purine and pyrimidine uptake and indirectly by intracellular metabolism to 5-fluorouracil. Flucytosine enters the fungal cell via cytosine permease; thus, flucytosine is metabolized to 5-fluorouracil within fungal organisms. The 5-fluorouracil is extensively incorporated into fungal RNA and inhibits synthesis of both DNA and RNA. The result is unbalanced growth and death of the fungal organism. It also appears to be an inhibitor of fungal thymidylate synthase.

N-Acryloylglycine

2-[(1-Hydroxyprop-2-en-1-ylidene)amino]acetate

C5H7NO3 (129.0425912)


N-Acryloylglycine is an acyl glycine. Acyl glycines are normally minor metabolites of fatty acids. However, the excretion of certain acyl glycines is increased in several inborn errors of metabolism. In certain cases the measurement of these metabolites in body fluids can be used to diagnose disorders associated with mitochondrial fatty acid beta-oxidation. Acyl glycines are produced through the action of glycine N-acyltransferase (EC 2.3.1.13) which is an enzyme that catalyzes the chemical reaction:. acyl-CoA + glycine < -- > CoA + N-acylglycine.

C5H7NO3 (129.0425912)


Pyroglutamic acid, also known as pyroglutamate or (-)-2-pyrrolidone-5-carboxylic acid, belongs to alpha amino acids and derivatives class of compounds. Those 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. Pyroglutamic acid is soluble (in water) and a weakly acidic compound (based on its pKa). Pyroglutamic acid can be found in a number of food items such as sesame, mexican groundcherry, sorghum, and breakfast cereal, which makes pyroglutamic acid a potential biomarker for the consumption of these food products. Pyroglutamic acid can be found primarily in most biofluids, including blood, feces, urine, and saliva, as well as in human brain, prostate and skin tissues. Pyroglutamic acid exists in all eukaryotes, ranging from yeast to humans. In humans, pyroglutamic acid is involved in the glutathione metabolism. Pyroglutamic acid is also involved in several metabolic disorders, some of which include 5-Oxoprolinuria, gamma-glutamyltransferase deficiency, gamma-glutamyl-transpeptidase deficiency, and glutathione synthetase deficiency. Moreover, pyroglutamic acid is found to be associated with schizophrenia, glutathione synthetase deficiency, and 5-oxoprolinase deficiency. Pyroglutamic acid is a non-carcinogenic (not listed by IARC) potentially toxic compound.
