Note
7,8-Dihydroneopterin, also known as dihydroneopterin, belongs to the class of organic compounds known as biopterins and derivatives. These are coenzymes containing a 2-amino-pteridine-4-one derivative. They are synthesized in several parts of the body, including the pineal gland. 7,8-Dihydroneopterin is a strong basic compound (based on its pKa). Within humans, 7,8-dihydroneopterin participates in a number of enzymatic reactions. In particular, 7,8-dihydroneopterin can be biosynthesized from sepiapterin; which is catalyzed by the enzyme sepiapterin reductase or carbonyl reductase [NADPH] 1. In humans, 7,8-dihydroneopterin is involved in the metabolic disorder called hyperphenylalaninemia due to 6-pyruvoyltetrahydropterin synthase (PTPS) deficiency. 7,8-Dihydroneopterin is produced by human monocyte-derived macrophages upon stimulation with interferon-gamma. Increased amounts of 7,8-dihydroneopterin in human body fluids are found in many disorders, including viral infections and autoimmune diseases (PMID: 12804528).
