Biochemistry of the Pteridines

Angewandte Chemie International Edition in English, 1972
AbstractBiochemical information about the ubiquitous pteridines has become generally available only within the last fifteen years. This delay can be traced to the chemical lability of these compounds and their small concentrations in organisms. New methods of isolation and isotopic techniques have provided data on the biosynthesis, anabolism, and ...

Polarographic Study of Pteridines

Journal of Pharmaceutical Sciences, 1966
The electronegativity of the half-wave potentials of a series of pteridine congeners was found to be related to the substituent groups. The 2,4,7-triaminopteridines, 7-substituted 4-amino-2-aryl-6-pteridinecarboxarnides, and 4,7-diamino-2-aryl-6-pteridinecarboxamides were characterized, in that order, by decreasingly lower electronegative half-wave ...

Reductone and the Synthesis of Pteridines

Nature, 1948
As we have pointed out1 that the 3-carbon atom unit comprising the ring atoms 6 and 7 and the exocyclic carbon atom (indicated in heavy type) in pteroic acid (I) might be derived from a triose, 3-phosphoglyceraldehyde and phosphodihydroxyacetone being specifically mentioned, the suggestion by O‘Meara, McNally and Nelson2 that the strongly reducing non ...

A Synthesis of Pteridine

Nature, 1948
ALTHOUGH many derivatives of pteridine, both natural and synthetic, are known, the parent substance pteridine (I) does not appear to have been described. This substance has now been prepared by the condensation of 4 : 5-diaminopyrimidine with glyoxal bisulphite.

Pteridines and affective disorders

Acta Neuropsychiatrica, 2002
The pteridine tetrahydrobiopterin (BH4) is an essential cofactor in the biosynthesis of dopamine, (nor)epinephrine, serotonin and nitric oxide (NO). Furthermore, BH4 has a direct influence on release mechanisms of these neurotransmitters and on serotonin receptor binding activityimmunology.
