Indole-3-carbaldehyde (I3A), also known as indole-3-aldehyde and 3-formylindole, is a metabolite of dietary L-tryptophan which is synthesized by human gastrointestinal bacteria, particularly species of the Lactobacillus genus.
Indole-3-acetaldehyde is a substrate for retina-specific copper amine oxidase, aldehyde dehydrogenase X (mitochondrial), amine oxidase B, amiloride-sensitive amine oxidase, aldehyde dehydrogenase (mitochondrial), fatty aldehyde dehydrogenase, 4-trimethylaminobutyraldehyde dehydrogenase, aldehyde dehydrogenase (dimeric NADP-preferring), aldehyde ...
Indole is an organic compound with the formula C 6 H 4 CCNH 3. Indole is classified as an aromatic heterocycle. It has a bicyclic structure, consisting of a six-membered benzene ring fused to a five-membered pyrrole ring. Indoles are derivatives of indole where one or more of the hydrogen atoms have been replaced by substituent groups.
Indole-3-acetic acid (IAA, 3-IAA) is the most common naturally occurring plant hormone of the auxin class. It is the best known of the auxins, and has been the subject of extensive studies by plant physiologists. [1] IAA is a derivative of indole, containing a carboxymethyl substituent. It is a colorless solid that is soluble in polar organic ...
The 3 substrates of this enzyme are (indol-3-yl)acetaldehyde, H 2 O, and O 2, whereas its two products are (indol-3-yl)acetate and H 2 O 2. This enzyme belongs to the family of oxidoreductases , specifically those acting on the aldehyde or oxo group of donor with oxygen as acceptor.
They are produced by methylation of indole nucleus at position 3 and the subsequent nucleophilic addition at the carbon atom in positions 2 with the closure of the ethylamino group into a ring. A typical representative of this group is physostigmine , [ 23 ] which was isolated by Jobst and Hesse in 1864.
Lactobacillaceae (Lactobacillus s.l.) species metabolize tryptophan into indole-3-aldehyde (I3A) which acts on the aryl hydrocarbon receptor (AhR) in intestinal immune cells, in turn increasing interleukin-22 (IL-22) production. [10] Indole itself triggers the secretion of glucagon-like peptide-1 (GLP-1) in intestinal L cells and acts as a ...
Replacing an indole with a 3,4-dimethoxyphenyl group give the reaction named the Pictet–Spengler tetrahydroisoquinoline synthesis. Reaction conditions are generally harsher than the indole variant, and require refluxing conditions with strong acids like hydrochloric acid, trifluoroacetic acid or superacids.
