Identification of xanthurenic acid 8-O-beta-D-glucoside and xanthurenic acid 8-O-sulfate as human natriuretic hormones.
Hormonal regulation of salt excretion and water balance by the kidneys is well documented. Before 1961, it was widely believed that the glomerular filtration rate and the steroid hormone aldosterone controlled sodium balance in the body. In 1961, deWardener et al. [de Wardener HE, Mills IH, Clapham WF, Hayter CJ (1961) Clin Sci 21:249-258] showed that when these two variables were controlled, t...

متن کاملTryptophan metabolite excretion by the American cockroach.
Abstrac t -1 . Three fluorescing materials have been discovered in excreta from the American cockroach, Periplaneta americana (L.), and found to increase in concentration as dietary nitrogen increases. 2. These compounds have been identified as kynurenic, xanthurenic and 8-hydroxyquinaldic acids. 3. Feeding cockroaches antibiotic eliminates 8-hydroxyquinaldic acid production, presumably by inhi...
متن کاملXanthurenic Acid in Depression
An altered or increased excretion of xanthurenic acid (XA) in urine for 24h after intake of 5 grams L-tryptophan (Trp) at 10:00 p.m. is considered a measure of strain in the organism. XA was studied in 104 hospitalized depressive patients (DSM-HI : 296.23; 296.33) and 15 controls. Zung anxiety and depression scales were rated. The XA-excretion after Trp load has a wider range than the blank XA-...
متن کاملPhotoinduced tautomeric transformations of xanthurenic acid.
The 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 solutions, more than one tautomeric form is prese...
