Introduction | The natural compound indole -3-propionic acid (IPA) is an important intermediate for the synthesis of indole alkaloid lysergic acid. The combined properties of indole 3-propionic acid make it particularly useful in preventing the cytotoxic effects of amyloid beta protein on cells, treating all fibril forming diseases, and protecting cells from oxidative damage. |
mechanism of action | indole -3-propionic acid is the deamination product of tryptophan, which can protect the hippocampus (Gerbil Study) protects against ischemic injury and oxidative stress. Its ability to protect neurons in this way is attributed to its powerful antioxidant effect. Indole -3-propionic acid has also been hypothesized to have a protective effect on the thyroid gland. |
Medical use | by contacting cells with an effective amount of indole-3-propionic acid or A salt or ester thereof, prevents the cytotoxic effect of amyloid beta protein on cells. In addition, a fibril forming disease in a human patient is treated by administering to the human patient an indole-3-propionic acid or a salt or ester thereof in an amount effective to prevent or reverse fibril formation. Oxidation in the biological sample is reduced by contacting the biological sample with an effective amount of indole-3-propionic acid or a salt or ester thereof. In addition, diseases or other conditions in which free radicals and/or oxidative stress occur can be treated by administering an effective amount of indole-3-propionic acid or a salt or ester thereof. |
Use | for plant growth hormone pharmaceutical intermediate |
production method | diazotization of aniline hydrochloride with sodium nitrite under acidic conditions, followed by reaction with ethyl cyclopentanone-2-carboxylate, phenylhydrazone α-oxyethylene is obtained. The obtained phenylhydrazone was dissolved in an ethanol solution containing 20% sulfuric acid and reacted under reflux for 4H to produce indole -2-carboxylic acid -3-propionic acid. It was heated to 225-230 °c, and the reaction was completed in about half an hour. The reaction mixture was dissolved in boiling water, decolorized with activated carbon, and filtered. The filtrate was concentrated, crystallized, and recrystallized from hot water to obtain 3-indolylpropionic acid. |
