IAA

3-Indoleacetic acid (indolylacetic acid) (IAA) is the most common plant hormone of the auxin class and it regulates various aspects of plant growth and development.

3-Indoleacetic acid sodium (Heteroauxin sodium salt) is a naturally occurring plant hormone of the auxin class. It can stimulate cell elongation and division, promoting plant growth and development. However, at high concentrations, it exhibits growth inhibiting effects, including epinasty and prevention of shoot and root growth. This latter effect formed the basis for which synthetic auxins were developed as herbicides and bioregulators in agriculture.

trans-3-Indoleacrylic acid is one of the endogenous metabolites that inhibits RSL3-induced ferroptosis and can be used to study colorectal cancer.

1H-Indole-3-carboxaldehyde (3-Formylindole), also known as 3-formylindole or 3-indolealdehyde, belongs to the class of organic compounds known as indoles. Indoles are compounds containing an indole moiety, which consists of pyrrole ring fused to benzene to form 2,3-benzopyrrole. 1H-Indole-3-carboxaldehyde is an extremely weak basic (essentially neutral) compound (based on its pKa). Outside of the human body, 1H-Indole-3-carboxaldehyde has been detected, but not quantified in, several different foods, such as gram beans, brussel sprouts, cucumbers, cereals and cereal products, and white cabbages. This could make 1H-indole-3-carboxaldehyde a potential biomarker for the consumption of these foods. A heteroarenecarbaldehyde that is indole in which the hydrogen at position 3 has been replaced by a formyl group.

4-Chloroindole-3-acetic acid (4-Cl-IAA) is a chlorinated analog of indole-3-acetic acid (IAA), functioning as a plant hormone. It is found in the seeds of Medicago truncatula, Melilotus indicus, and Trifolium.
