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 ...

Measurement of changes in urinary neopterin and total neopterin in body builders using SCX HPLC
Pteridines, 2014 Body building is a sport where ultrastructual damage to muscle fibres aids the development of dense muscle layers. Using a new strong cation exchange (SCX) based chromatography technique to measure neopterin and 7,8-dihydroneopterin, we investigated ...

Radical-mediated ring contraction in the biosynthesis of 7-deazapurines [PDF]
, 2015 Pyrrolopyrimidine containing natural products are widely distributed in Nature. The biosynthesis of the 7-deazapurine moiety that is common to all pyrrolopyrimidines entails multiple steps, one of which is a complex radical-mediated ring contraction ...

Pteridines, 2002 Neopterin, 7,8-dihydroneopterin and 5,6,7,8-terahydroneopterm are secreted by human macrophages after activation by interferon-γ. The biological stability of the reduced pterins is less than one hour and therefore distinctly lower than that of neopterin.
