Metabolite Identification
Common Name3-Carboxy-4-methyl-5-propyl-2-furanpropanoate
Description3-Carboxy-4-methyl-5-propyl-2-furanpropionic acid (CMPF) is also called 3-carboxy-4-methyl-5-propyl-2-furanpropanoic acid and 2-(2-carboxyethyl)-4-methyl-4-propylfuran-3-carboxylic acid. CMPF is significantly accumulated in the serum of chronic kidney disease patients and is considered to be a potent uremic toxin (PMID: 8734460 ) and identified as a uremic toxin according to the European Uremic Toxin Working Group (PMID: 22626821 ). There are several minor derivatives of CMPF that have been detected in serum and urine including 3-carboxy-4-methyl-5-pentyl-2-furanpropionic acid, 3-carboxy-4-methyl-5-ethyl-2-furanpropionic acid, and 3-carboxy-5-propyl-2-furanpropionic acid. CMPF was first detected in human urine in 1979 (PMID: 12388676 ) and it is believed to be formed from the consumption of fish, vegetables, and fruits (PMID: 19083276 ">19083276 ; PMID: 12388676 ). CMPF is a strong inhibitor of mitochondrial respiration and is associated with thyroid dysfunction (PMID: 19083276 ). CMPF also directly inhibits renal secretion of various drugs and endogenous organic acids by competitively inhibiting OAT3 transporters (PMID: 11967025 ). It is also thought to contribute to various neurological abnormalities because it inhibits the transport of organic acids at the blood-brain barrier (PMID: 12388676 ).
