Metabolite Identification
Common NameSepiapterin
DescriptionSepiapterin, also known as lopac-S-154, belongs to the class of organic compounds known as pterins and derivatives. These are polycyclic aromatic compounds containing a pterin moiety, which consist of a pteridine ring bearing a ketone and an amine group to form 2-aminopteridin-4(3H)-one. Sepiapterin is an extremely weak basic (essentially neutral) compound (based on its pKa). Sepiapterin is a potentially toxic compound. Sepiapterin, with regard to humans, has been linked to the inborn metabolic disorder sepiapterin reductase deficiency.

Reactions
Sepiapterin + NADPH → 7,8-Dihydroneopterin + NADPdetails
General function:
Lipid transport and metabolism
Specific function:
NADPH-dependent reductase with broad substrate specificity. Catalyzes the reduction of a wide variety of carbonyl compounds including quinones, prostaglandins, menadione, plus various xenobiotics. Catalyzes the reduction of the antitumor anthracyclines doxorubicin and daunorubicin to the cardiotoxic compounds doxorubicinol and daunorubicinol. Can convert prostaglandin E2 to prostaglandin F2-alpha. Can bind glutathione, which explains its higher affinity for glutathione-conjugated substrates. Catalyzes the reduction of S-nitrosoglutathione (By similarity).
