7-Biopterin

7-Biopterin is a 7-substituted pterin. It is formed by non-enzymatic rearrangement of 4a-hydroxy-tetrahydropterin in the absence of pterin-4a-carbinolamine dehydratase (PCD) in vitro and levels are elevated in the urine of hyperphenylalaninemia patients carrying heterozygous mutations in the PCBD gene encoding PCD.Formal Name: 2-amino-7-[(1R,2S)-1,2-dihydroxypropyl]-4(3H)-pteridinone.
