Analysis and clinical significance of pterins

Journal of Chromatography B: Biomedical Sciences and Applications, 1988
This review briefly describes the biochemistry of pterins, their involvement in pathological processes and the use of pterin measurement in diagnosis and monitoring of disease. Chromatographic and other methods of pterin analysis are detailed with particular emphasis being placed on the need for correct sample collection and handling.

The Biosynthesis of Folate and Pterins and Their Enzymology

2010
This work presents a definitive interpretation of the current status of and future trends in natural products-a dynamic field at the intersection of chemistry and biology concerned with isolation, identification, structure elucidation, and chemical characteristics of naturally occurring compounds such as pheromones, carbohydrates, nucleic acids, and ...

Calcium pterin as an antitumor agent

International Journal of Pharmaceutics, 2004
A series of in vivo studies are reported that provide evidence for an immunologically mediated mechanism for the antitumor response from a calcium pterin (CaPterin) suspension. Strong antitumor efficacy was demonstrated in fully immunocompetent female C3H/HeN-MTV+ mice (retired breeders) presenting spontaneous mammary gland adenocarcinomas.

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.
