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.
The process begins by producing 7-chloroindole-3-acetamide by treating 7-chloroindole with a series of reagents, shown farther down. This molecule is then glycosylated and reacted with methyl 7-chloroindole-3-glyoxylate to produce an intermediate that goes on to stabilize into the final product.
There can be many years between promising laboratory work and the availability of an effective anti-cancer drug: Monroe Eliot Wall discovered anti-cancer properties in Camptotheca in 1958, but it was not until 1996 – after further research and rounds of clinical trials – that topotecan, a synthetic derivative of a chemical in the plant, was ...
Moreover, 3-hydroxymethyl-beta-carboline blocks the sleep-promoting effect of flurazepam in rodents and – by itself – can decrease sleep in a dose-dependent manner. [16] Another derivative, methyl-β-carboline-3-carboxylate, stimulates learning and memory at low doses but can promote anxiety and convulsions at high doses. [ 15 ]
Indole-3-carbinol induces a G1 growth arrest of human reproductive cancer cells. [9] This is potentially relevant to the prevention and treatment of cancer, as the G1 phase of cell growth occurs early in the cell life cycle, and, for most cells, is the major period of cell cycle during its lifespan.
At very low concentrations, however, it has a flowery smell, [3] and is a constituent of many perfumes. It also occurs in coal tar. It has been identified in cannabis. [4] It is the main volatile compound in stinky tofu. [5] When indole is a substituent on a larger molecule, it is called an indolyl group by systematic nomenclature.
Vosilasarm has been assessed in clinical trials in women with breast cancer at doses ranging from 50 to 150 mg/day, with the maximum safe and tolerated dose being 100 mg/day. [ 10 ] [ 3 ] [ 2 ] The drug sold via black-market Internet suppliers and used non-medically has been reported to be taken at doses of 5 to 30 mg/day, with unknown adverse ...
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 ...
