Biopterin: Reduced form in Ascaris lumbricoides

Experimental Parasitology, 1970
Abstract A blue fluorescent substance which was supposed to be “Ascaris-blue” was extracted from Ascaris muscle. After Chromatographic purification, the substance was identified as biopterin, 2-amino-4-hydroxy-6-(erythro-1′, 2′-dihydroxypropyl)pteridine.

A new synthesis of biopterin

Journal of the Chemical Society C: Organic, 1969
An unambiguous synthesis of biopterin [2-amino-6-(L-erythro-1,2-dihydroxypropyl)pteridin-4-(3H)-one] is described; based on an improved synthesis of L-neopterin. The synthesis yields biopterin, a naturally occurring pteridine, in a pure, crystalline form without recourse to chromatography. D-Biopterin and D-neopterin are also described.

Hyperphenylalaninaemia caused by defects in biopterin metabolism

Journal of Inherited Metabolic Disease, 1985
AbstractThe hepatic phenylalanine hydroxylating system consists of three essential components, phenylalanine hydroxylase, dihydropteridine reductase and the non‐protein coenzyme, tetrahydrobiopterin. The reductase and the pterin coenzyme are also essential components of the tyrosine and tryptophan hydroxylating systems.

New aspects in biopterin biosyntheses

1981
A human kidney preparation which catalyzes the conversion of D-erythro-dihydroneopterin triphosphate (NeH2P3) to dihydrobiopterin (BH2), sepiapterin, pyruvate and pterin in the presence of Mg++ and NADPH was studied. After incubation with NeH2P3, the formation of Tanaka’s compound X (probably 6-(1’,2’-dioxopropyl)-7,8-dihydropterin) could be proven as ...
