Automatic determination of xanthurenic acid
Analytical Biochemistry, 1966Abstract An automatic method is described for the colorimetric determination of xanthurenic acid in urine which proved effective in an extensive series of analyses. This procedure is definitely superior to the conventional method of colorimetric determination with regard to both accuracy and working speed.

Photochemical Studies on Xanthurenic Acid¶
Photochemistry and Photobiology, 2000The tryptophan metabolite xanthurenic acid (Xan) has been isolated from aged human cataractous lenses. The photophysical properties of Xan were examined to determine if it is a potential chromophore for age-related cataractogenesis. We found that Xan produces singlet oxygen (psi delta = 0.17 in CD3OD) with the same efficiency as the lenticular ...

Photoinduced tautomeric transformations of xanthurenic acid
Physical Chemistry Chemical Physics, 2010The properties of xanthurenic acid (XAN) in ground and photoexcited states have been studied using steady-state and time-resolved optical methods as well as quantum chemistry calculations. In neutral aqueous solution and in alcohols, XAN is present in a single tautomeric form (keto form), whereas in aprotic solvents and probably in basic aqueous ...
