IUPAC 名称
2-amino-7,8-dihydroxy-6-(1,2,3-trihydroxypropyl)-3,4,5,6,7,8-hexahydropteridin-4-one
描述
2-Amino-4-oxo-6-(1',2',3'-trihydroxypropyl)-diquinoid-7,8-dihydroxypterin is a pterin derivative. Pterin is a heterocyclic compound composed of a pyrazine ring and a pyrimidine ring with Several tautomers; the pyrimidine ring has a carbonyl oxygen and an amino group. As a group, pterins are compounds that are derivatives of 2-amino-4-oxopteridine, with additional functional groups attached to the pyrazine ring. Pterins were first discovered in the pigments of butterfly wings and perform many roles in coloration in the biological world. Pterins also function as cofactors in enzyme catalysis .
Some pterin derivatives (biopterin, 6-formylpterin, 6-carboxypterin) accumulate in the skin of patients affected by vitiligo, a depigmentation disorder, where the protection against UV radiation fails due to the lack of melanin. Pterins participate in biologically important photosensitization processes; for example, pterins act as sensitizers in photochemical reactions that induce DNA damage4,5 and are able to generate singlet molecular oxygen6 and other reactive oxygen species (PMID: 19199487).
