ADVANCES IN CLINICAL CHEMISTRY
Subsequent studies by the same group (W7) have shown that the increased
endogenous fluorescence in patients with chronic renal failure is due to the
unconjugated pteridine, xanthopterin (2-amino-4,6-pteridinedione, 179 Da; see
Table 4 ...

The Chemistry of Heterocyclic Compounds, Fused Pyrimidines: ...
(160) (I611 The ordinary metathetical reactions of xanthopterin are discussed in
appropriate sections of this book and are not listed here. The physical properties,
information on salts, and degradations of xanthopterin have been extracted from

Changes in the supply of precursors alters the kinetic balance among the various
reactions in this pathway because the enzyme, xanthine dehydrogenase, which
oxidizes xanthopterin to leucopterin, is strongly inhibited by the precursor of ...
Michael J. Berridge, J. E. Treherne, Sir Vincent Brian Wigglesworth, 1985
On the basis of their chemical studies, Hirata, Nakanishi, and Kikkawa (1950b)
have called this new xanthopterin-like substance "xanthopterin-B," its suflix "B"
coming from Bombyx. It should be pointed out that xanthopterin-B is present with
...

Biochromy, Natural Coloration of Living Things
Its nitrogen content is lower than that of most pterins; it shows fluorescence in
dilute acetic acid, and adheres more firmly to adsorbent powders than does
xanthopterin. Both of these pterins are reducible to colorless derivatives by
treatment ...

The Complete book on Natural Dyes & Pigments
The condensation of the pyrimidine (XIII) with mesoxalic ester results in the
production of xanthopterin carboxylic acid (XVIII) as well as isoxanthopterin
carboxylic acid (XVI) and the first of these, unlike the second, is difficult to
decarboxylate; ...

Biosynthesis in Insects
Leucopterin is colourless, xanthopterin and chrysopterin are yellow, erythropterin

similarity between the third and fourth steps in this sequence and the third step in
the ...
