Synthesis of new indolecarboxylic acids related to the plant hormone indoleacetic acid IAA

open access: yesJournal of the Brazilian Chemical Society, 2003
The synthesis of 5,6-methylenedioxy-indol-3-yl-methanoic acid 8 and 5,6-methylenedioxy-indol-3-yl-acetic acid 13 is described. Piperonal was employed as starting material, and the construction of the heterocyclic ring based on the Hemetsberger reaction ...

Metabolism of Indoleacetic Acid in Rust Diseases. II. Metabolites of Carboxyl-labeled Indoleacetic Acid in Tissues [PDF]

open access: yesPlant Physiology, 1964
In a previous paper (6), we reported different rates of decarboxylation of indoleacetic acid (IAAC14OOH) by healthy and rust-affected wheat leaves in the dark. As a result of infection the rate of decarboxylation first increased, but several days later, as the rust began to sporulate, declined to become much lower than that of healthy leaves.

Serum Metabolic Profiles of Chinese Women With Perimenopausal Obesity Explored by the Untargeted Metabolomics Approach

open access: yesFrontiers in Endocrinology, 2021
By far, no study has focused on observing the metabolomic profiles in perimenopause-related obesity. This study attempted to identify the metabolic characteristics of subjects with perimenopause obesity (PO).

Quantification of Gut Microbiota Dysbiosis-Related Organic Acids in Human Urine Using LC-MS/MS

open access: yesMolecules, 2022
Urine organic acid contains water-soluble metabolites and/or metabolites—derived from sugars, amino acids, lipids, vitamins, and drugs—which can reveal a human’s physiological condition. These urine organic acids—hippuric acid, benzoic acid, phenylacetic
