Define indole. indole synonyms, indole pronunciation, indole translation, English dictionary definition of indole. n. 1. A white crystalline compound, C8H7N, obtained from coal tar or various plants and produced by the bacterial decomposition of tryptoph
Compared with healthy adult rats, the serum metabolome in aging rats was altered and the abundance of indole metabolites, including indoxyl sulfate, indole-3-carboxylic acid, and indole-5-carboxylic acid, was decreased significantly. In LS180 cells, indole-3-carboxylic acid amplifi...
In the present study, several tryptophan catabolites, including IAld, 2-indole carboxylic acid (2-ICA), 3-indolebutyric acid (IBA), indole-3-carboxylic acid (I3CA), and indole-3-methyl acetate, were present at lower levels in diarrheal piglets. A correlation analysis between the six ...
carboxylic acids have been described. Good yields of pyrrolecarboxylic esters have also been obtained using dimethyl or diethyl sulfate under mildly basic conditions〈79JHC1065, 79CI(L)522〉. Base-catalyzed transesterification of pyrrolecarboxylic esters, particularly the 2-isomers, is possible〈...
Other tryptophan-derived compounds, including tryptamine (III-2), indole-3-acetic acid (III-3), and 3-indoxyl sulfate (I3S, III-4), have also been identified as AhR agonists. Some species of bacteria such as Lactobacillus can use tryptophan instead of glucose as an energy source, and ...
and ethylene glycol are catalytically reacted in the vapor phase in the presence of a catalyst containing a lanthanum compound (especially preferred examples; lanthanum sulfate, lanthanum bromide and lanthanum chloride) to obtain indoles (example; 5- hydroxyindole, etc.). Ethylene glycol and anilines...
°-5° C. for at least 1 hour, filtered and washed with water until sulfate free. After drying, the product weighed 42.1 g., which corresponds to a yield of 83.2%, m.p. 166°-169° C., assay titration 98.6%. EXAMPLE 3 Indoline-2-Carboxylic Acid From Indole-2-Carboxylic Acid...
(Fig.4C, Fig. S6F), which suggested its potential role in mitigating colitis. Comparison between the metabolic profiles of colon contents from BG- and vehicle-treated mice exhibited significant changes in the metabolites among colitic mice with chenodeoxycholic acid 3-sulfate, hydroxymalonate, ILA, ...
Organic layers were collected, filtered over anhydrous sodium sulfate, and dried in-vacuo to obtain the desired products with moderate to good yields. Procedure for the synthesis of 4-chloro-N-(9H-fluoren-2-yl)benzamide (18) To a stirred solution of 4-chlorobenzoic acid (100 mg, 0.64 mmol...
