ABSTRACT Background Tetrahydrobiopterin (BH4) deficiencies comprise a group of five neurometabolic disorders caused by five genetic defects responsible for BH4 biosynthesis and regeneration. Their global prevalence remains unknown, and variance exists among different countries.

Studies on the regulation of endothelial nitric oxide synthase in endothelial dysfunction [PDF]
Ischaemic heart disease and cerebrovascular disease are the leading causes of morbidity and mortality in the world. The underlying progression of the disease is linked to a reduction in the bioavailability of nitric oxide. One factor contributing to this

Insulin Reverses D-Glucose–Increased Nitric Oxide and Reactive Oxygen Species Generation in Human Umbilical Vein Endothelial Cells [PDF]
Vascular tone is controlled by the L-arginine/nitric oxide (NO) pathway, and NO bioavailability is strongly affected by hyperglycaemia-induced oxidative stress.

Mapping an atlas of tissue-specific drosophila melanogaster metabolomes by high resolution mass spectrometry [PDF]
Metabolomics can provide exciting insights into organismal function, but most work on simple models has focussed on the whole organism metabolome, so missing the contributions of individual tissues.

First Synthesis of Asperopterin A, an Isoxanthopterin Glycoside from Aspergillus Oryzae [PDF]
The key precursor, N-2-(N,N -dimethylaminomethylene)-6-hydroxymethyl-8-methyl-3-[2-(4-nitrophenyl)ethyl]-7-xanthopterin (16) was efficiently prepared from 2,5-diamino-6-methylamino-3H-pyrimidin-4-one (5) and ethyl 3-(tert-butyldimethylsilyloxy)-2 ...

Administration of 2,4-diamino-6-hydroxypyrimidine (DAHP) in the diet of rats reduced total biopterins in plasma, brain and liver. The levels of dihydropteridine reductase (DHPR) and the rate of biopterin biosynthesis were unaffected.

Biopterin responsive phenylalanine hydroxylase deficiency [PDF]
Phenylketonuria (PKU) is an autosomal recessive disorder caused by mutations in the phenylalanine hydroxylase (PAH) gene. There have been more than 400 mutations identified in the PAH gene leading to variable degrees of deficiency in PAH activity, and consequently a wide spectrum of clinical severity.
