Masuda, Minoru published the artcileUrinary aromatic metabolites in schizophrenia, Category: indole-building-block, the publication is J. Nervous Mental Disease (1960), 125-33, database is CAplus.
The studies were carried out on 50 acute schizophrenic and 53 nonpsychotic subjects. Overnight urine specimens were prepared as recommended by Dalgleish (CA 51, 3715b) and analyzed by paper chromatography. In the schizophrenics the increased excretion of aromatic compounds was due to indolic, but not phenolic, substances, especially indoleacetic acid, 5-hydroxyindoleacetic acid, and indican. There was also increased excretion of urea. No metabolite was found regularly which would characterize the schizophrenic group.
J. Nervous Mental Disease published new progress about 2642-37-7. 2642-37-7 belongs to indole-building-block, auxiliary class Indole,Salt,Sulfonate,Inhibitor,Inhibitor, name is Potassium 1H-indol-3-yl sulfate, and the molecular formula is C8H6KNO4S, Category: indole-building-block.
