Tryptophan metabolites from young human lenses and the photooxidation of ascorbic acid by UVA light.
PURPOSE To determine whether there are UVA light-responsive sensitizers in young human lenses capable of initiating the oxidation of ascorbic acid in the absence of oxygen. METHODS Lens homogenates were fractionated, and low-molecular-weight (LMW) components were separated from the proteins by filtration through a 3000-MWt cutoff filter. Aliquots of each fraction were assayed for sensitizer a...
متن کاملStudies on the Effect of Tryptophan Deficiency on the Metabolic Products of Tryptophan and Niacin.
In 1906, Hopkins and Willcox reported that tryptophan was essential for animals nutrition. Since then, the effect of tryptophan deficiency upon animal nutrition has been discussed by many authors. Recently the interrelation between trypto phan and niacin metabolism was demonstrated. On the other hand, Kotake and his collaborators studied tryptophan metabolism, being especially interested in kyn...

A method for the synthesis of 1-(5-methyl-2-furoyl)thymine (7) and 1-(5-methyl-2-furyl)thymine (8) is described. Trimethylsilyliodide catalysed addition of 5-methyl-2,4-bis(trimethylsilyloxy)pyrimidine (9) to 2-methyl-2,5-dihydro-2,5-dimethoxyfuran yielded the new thymine derivative 13. Photooxidations of 7 and 8 gave not the expected addition products but furan endoperoxides and hydroperoxides...
