An Efficient Synthetic Route for a Versatile Ciliapterin Derivative and the First Ciliapterin D-Mannoside Synthesis [PDF]
, 2008 The key precursor, N(2)-(N,N-dimethylaminomethylene)-1’-O-(4-methoxybenzyl)-3-[2-(4-nitrophenyl)ethyl]ciliapterin (15) was efficiently prepared from D-xylose via an improved route.

Degeneration of Rat Retina is Paralleled by an Imbalance of the Redox Mechanism of Pteridines
Pteridines, 1996 The RCS rat suffers from a genetic degeneration of retinal cell We have examined the pattern of oxidized and reduced monapterin and biopterin in retinas from RCS retinas and controls.

Molecular Ecology, Volume 34, Issue 19, October 2025.ABSTRACT Colouration and patterning have been implicated in lineage diversification across various taxa, as colour traits are heavily influenced by sexual and natural selection. Investigating the biochemical and genomic foundations of these traits therefore provides deeper insights into the interplay between genetics, ecology and social interactions in

Undetectable Levels of CSF Amyloid-β Peptide in a Patient with 17β-Hydroxysteroid Dehydrogenase Deficiency [PDF]
, 2011 17β-hydroxysteroid dehydrogenase 10 (HSD10) deficiency is a rare X-linked inborn error of isoleucine catabolism. Although this protein has been genetically implicated in Alzheimer's disease pathogenesis, studies of amyloid-β peptide (Aβ) in patients with

Characterization of Underivatized Pterins by Laser Desorption Fourier Transfonn Mass Spectrometry
Pteridines, 1993 Laser desorption FfMS provides a powerful method for examining the structures of underivatized pteridines. (M + Na)+ and (M + K)+ ions are generated by laser desorption and can be used to determine molecular weights. The negative ion spectra provide more

Development of chemical proteomics for the folateome and analysis of the kinetoplastid folateome [PDF]
, 2018 The folate pathway has been extensively studied in a number of organisms, with its essentiality exploited by a number of drugs. However, there has been little success in developing drugs that target folate metabolism in the kinetoplastids.

Mechanistic Study of ROS-photogeneration by Pterin
Pteridines, 2011 Pterins are widespread in biological systems and possess photosensitizing activities. In the present study, the photosensitization mechanism of acid form of pterin (PTA) and basic form of pterin (PTB) is investigated by means of density functional theory
