Paper Chromatography of Pterins

Nature, 1949
THE detection and identification of pterins in small quantities was carried out by Schopf and Becker1 in the course of their classical work on this class of pigments. They employed a chromatographic technique using 0·004 N aqueous hydrochloric acid or 0·01 N methyl alcoholic hydrochloric acid solutions on micro-absorption columns of alumina or ...

A Prebiotic Synthesis of Pterins

Chemistry – A European Journal, 2015
AbstractThe genesis of life on Earth is a hypothesis of evolutionary science that can be, at least partially, tested experimentally. The prebiotic synthesis of cofactors or coenzymes is a poorly explored issue, likely because their formation under plausible prebiotic conditions is not clear.

Nitric-Oxide-Synthase Inhibitors II — Pterin Antagonists/Anti-Pterins

2000
In addition to heme, flavin adenine dinucleotide (FAD) and flavin mononucleotide (FMN), nitric oxide synthases (NOS) require tetrahydrobiopterin (H4B). This was first demonstrated for homogenates of stimulated murine macrophages (KWON et al. 1989; TAYEH and MARLETTA 1989). Unlike other enzymes, e.g.
