Pteridines CII Synthesis and Characterization of Dimeric Lumazines

Pteridines, 1994
Reduction of 1.3-dimethyllumazine (1) by zinc dust in Ac2O/AcOH leads to the formation of 6-7 connected bis-Iumazinyl derivatives. Depending on the reaction conditions either 7 -(5-acetyl-5,6, 7,8-tetrahydro-1.3-dimethyllumazin- 6-yl)-l, 3 ...

Lethal mutations induced in Drosophila melanogaster by direct or indirect acid of pteridines [PDF]

, 1984
The experiments described in this paper show than synthetic pteridines, especially biopterin and pterin, injected directly into Drosophila melanogaster induce recessive lethals. On the contrary, -neopterin seems to have little effect.

Normalization of Urinary Pteridines by Urine Specific Gravity for Early Cancer Detection

, 2014
Background: Urinary biomarkers, such as pteridines, require normalization with respect to an individual\u27s hydration status and time since last urination.
