Neopterin-induced Suppression of Erythropoietin Production In Vitro
Pteridines, 1995 The production of neopterin increases in several diseases with activation of the ceIlular immune response. As previously shown serum concentrations of neopterin are inversely correlated with blood hemoglobin concentrations in the anemia of hematological ...

Urinary and Serum Pteridines in Liver Diseases
Pteridines, 1996 The aim of this mini-review is to show the usefulness of pteridines as clinical markers. We assayed urinary neopterin and xanthopterin levels in liver disease. Total pterins were oxidized by active carbon to yield xanthopterin.

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 an HPLC-MS method for the determination of natural pteridines in tomato samples
, 2016 En las plantas, las pteridinas reducidas son intermedios de la biosíntesis de folato, y la presencia de estos analitos en los procesos de biofortificación se considera crucial. Se optimizó un método simple de cromatografía líquida-espectrometría de masas

Synthesis, structure and photophysical properties of novel thiazolo[2,3-b]pteridines
Acta Chimica SlovenicaA one-pot synthesis of a series of thiazolo[2,3-b]pteridines, along with an alternative step-by-step procedure, has been developed. The regioselectivity of the heterocyclization was determined using a combination of physicochemical methods, including X ...

6-Acetonylisoxanthopterin: A Potent Inhibitor of Sepiapterin Reductase
Pteridines, 1991 The inhibitory effect of 6-/7-substituted (2'-oxo) pteridines and ichthyopterin was examined for sepiapterin reductase. 6-Acetonylisoxanthopterin and 6-acetonyl-2,4-diamino-7-hydroxypteridine showed pronounced competitive inhibitory effects to ...
