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.
In addition to the light- or H 2 O 2-induced formation of FICZ, a number of other enzymatic pathways have been identified to convert Trp to FICZ via the precursor I3A. [2] [3] Oxidative deamination of Trp by aromatic amino acid aminotransferases (ArAT) or L-amino oxidases (LAAO), one of which is the IL4-inducible enzyme IL4I1, converts Trp to indole-3-pyruvate, which after decarboxylation ...
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 Indoles are derivatives of indole where one or more of the hydrogen atoms have been replaced by substituent groups.
The compound's structure is based on the indole structure, but in which a second benzene ring is fused onto the five-membered ring at the 2–3 position of indole (equivalent to the 9a–4a double bond in carbazole, respectively). Carbazole is a constituent of tobacco smoke. [3]
Indole-3-carbinol is the subject of on-going biomedical research into its possible anticarcinogenic, [4] antioxidant, and anti-atherogenic effects. [5] Research on indole-3-carbinol has been conducted primarily using laboratory animals and cultured cells. [ 6 ]
β-Carboline (9H-pyrido[3,4-b]indole) represents the basic chemical structure for more than one hundred alkaloids and synthetic compounds. The effects of these substances depend on their respective substituent. Natural β-carbolines primarily influence brain functions but can also exhibit antioxidant [1] effects.
The first one consists of the degradation of the amino acid into indole-3-acetate. And in the second step, IAD catalyzes the decarboxylation of the indole-3-acetate to form the final product, skatole. The decarboxylation of indole-3-acetate is chemically difficult since it leaves an unstable carbanion because of the direct elimination of CO 2.
3,3′-Diindolylmethane (DIM) is a compound derived from the digestion of indole-3-carbinol, found in cruciferous vegetables, such as broccoli, Brussels sprouts, cabbage and kale. [1] It and its parent compound – indole-3-carbinol – are under laboratory research to determine their possible biological properties, particularly in anti-cancer ...
