Metabolite Identification
Common NameNeopterin
DescriptionNeopterin, also known as monapterin, belongs to the class of organic compounds known as biopterins and derivatives. These are coenzymes containing a 2-amino-pteridine-4-one derivative and are mainly synthesized in several parts of the body, including the pineal gland. Neopterin is a solid that is soluble in water. Neopterin is a catabolic product of guanosine triphosphate (GTP). In humans, it is involved in pterine biosynthesis and it also serves as a precursor in the biosynthesis of biopterin, which is an essential cofactor in neurotransmitter synthesis. Neopterin has been identified as a uremic toxin according to the European Uremic Toxin Working Group (PMID: 22626821 ). Most uremic toxins are metabolic waste products and are normally excreted in the urine or feces. Uremic toxins can cause kidney, liver and heart damage. They can also cause changes in mental status, such as confusion, reduced awareness, agitation, psychosis, seizures, and coma. Uremic toxins such as neopterin are actively transported into the kidneys via organic ion transporters (especially OAT3). Elevated levels of neopterin result from immune system activation, including from malignant cancer, allograft rejection, viral infection, and autoimmune disorders (PMID: 19500901 ). Measurement of neopterin concentration allows estimation of the extent of oxidative stress elicited by the immune system. Neopterin concentrations usually correlate with the extent and activity of a given disease, and are also used to monitor the course of the disease. Elevated neopterin concentrations are among the best predictors of adverse outcome in patients with HIV infection, in cardiovascular disease, and in various types of cancer.
