4203 Guanidoacetic acid Guanidinoacetic acid is a uremic toxin. Uremic toxins can be subdivided into three major groups based upon their chemical and physical characteristics: 1) small, water-soluble, non-protein-bound compounds, such as urea; 2) small, lipid-soluble and/or protein-bound compounds, such as the phenols and 3) larger so-called middle-molecules, such as beta2-microglobulin. Chronic exposure of uremic toxins can lead to a number of conditions including renal damage, chronic kidney disease and cardiovascular disease. Guanidoacetic acid is a metabolite in the Urea cycle and metabolism of amino groups, and in the metabolic pathways of several amino acids. This includes glycine, serine, threonine, arginine and proline metabolism. Guanidinoacetic acid is also a precursor of creatine, an essential substrate for muscle energy metabolism. 352-97-6 763 C3H7N3O2 White powder. 3.6 mg/mL at 15°C Endogenous, Ingestion, Dermal (contact) Uremic toxins such as guanidinoacetic acid are actively transported into the kidneys via organic ion transporters (especially OAT3). Increased levels of uremic toxins can stimulate the production of reactive oxygen species. This seems to be mediated by the direct binding or inhibition by uremic toxins of the enzyme NADPH oxidase (especially NOX4 which is abundant in the kidneys and heart) (A7868). Reactive oxygen species can induce several different DNA methyltransferases (DNMTs) which are involved in the silencing of a protein known as KLOTHO. KLOTHO has been identified as having important roles in anti-aging, mineral metabolism, and vitamin D metabolism. A number of studies have indicated that KLOTHO mRNA and protein levels are reduced during acute or chronic kidney diseases in response to high local levels of reactive oxygen species (A7869) Guanidino acetic acid (GAA) is synthesized in the liver and kidney from Arg and Gly and subsequently methylated by S-adenosylmethionine to form creatine. The conversion of guaniodacetate to creatinine in the liver causes a depletion of methyl groups. This causes homocysteine levels to rise, which has been shown to produce cardiovascular and skeletal problems. No indication of carcinogenicity to humans (not listed by IARC). Naturally produced by the body (endogenous). Is used as a supplement to enhance athletic performance. Acute exposure to guanidoacetic acid can lead to some mild skin and eye irritation. Chronic exposure to uremic toxins can lead to a number of conditions including renal damage, chronic kidney disease and cardiovascular disease. Chronically high levels of guanidoacetic acid are associated with at least 4 inborn errors of metabolism including: Argininemia, Guanidinoacetate methyltransferase deficiency, Guanidinoacetate Methyltransferase Deficiency (GAMT Deficiency) and S-Adenosylhomocysteine (SAH) Hydrolase Deficiency. As a uremic toxin, this compound can cause uremic syndrome. Uremic syndrome may affect any part of the body and can cause nausea, vomiting, loss of appetite, and weight loss. It can also cause changes in mental status, such as confusion, reduced awareness, agitation, psychosis, seizures, and coma. Abnormal bleeding, such as bleeding spontaneously or profusely from a very minor injury can also occur. Heart problems, such as an irregular heartbeat, inflammation in the sac that surrounds the heart (pericarditis), and increased pressure on the heart can be seen in patients with uremic syndrome. Shortness of breath from fluid buildup in the space between the lungs and the chest wall (pleural effusion) can also be present. Chronic Exposure: Kidney dialysis is usually needed to relieve the symptoms of uremic syndrome until normal kidney function can be restored. Acute Exposure: EYES: irrigate opened eyes for several minutes under running water. INGESTION: do not induce vomiting. Rinse mouth with water (never give anything by mouth to an unconscious person). Seek immediate medical advice. 2014-08-29T05:46:47Z 2016-11-09T01:09:02Z C00581 16344 GUANIDOACETIC_ACID DB02751 NMG true NC(=N)NCC(O)=O C3H7N3O2 InChI=1S/C3H7N3O2/c4-3(5)6-1-2(7)8/h1H2,(H,7,8)(H4,4,5,6) BPMFZUMJYQTVII-UHFFFAOYSA-N 117.1066 117.053826483 Endogenous Solid HMDB00128 CHEMBL281593 743 CHEM003109 2-carbamimidamidoacetic acid
