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 ...

Inhibition of protein oxidation by the macrophage-synthesised antioxidant 7,8-dihydroneopterin
Redox Report, 2001 Protein is the pivotal component involved in most cellular activities. As the most abundant cellular molecule, it is the most likely target of any reactive oxygen species (ROS).1 Often considered to be a passive target during free radical exposure, there is now considerable evidence showing ROS damage to proteins leads to the formation of reactive ...

Pteridines, 2015 Cold water immersion is thought to reduce the inflammatory response to injury. Using cultured mononuclear cells and human subjects in a mixed martial arts (MMA) contest, we examined the effect of cryotherapy on 7,8-dihydroneopterin and neopterin ...

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 ...

Pteridines and Lipid Metabolism
Pteridines, 1998 The effect of 9 different pteridines on fatty acid incorporation into phospholipids as well as on cholesterol and phospholipid content was compared in vitro using rat liver homogenate, Krebs-Ringer phosphate buffer containing 0.3 % albumin (pH=7.4 ...

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.

Auto-oxidation of 5,6,7 ,8-tetrahydroneopterin
Pteridines, 1998 Auto-oxidation of 5,6,7,8-tetrahydroneopterin (NPH4 ) in phosphate buffer solution (PBS) was examined using reversed-phase high-performance liquid chromatography.

MedComm – Oncology, Volume 5, Issue 3, September 2026.Ferroptosis is governed by the balance between reactive oxygen species (ROS)‐driven lipid peroxidation and a multi‐tiered antioxidant network. ROS sources include mitochondrial electron transport chain, voltage‐dependent anion channels, NADPH oxidases, and endoplasmic reticulum‐resident oxidoreductases, while antioxidant defenses span the primary GSH ...
