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 Indoles are derivatives of indole where one or more of the hydrogen atoms have been replaced by substituent groups.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 is released directly to the environment as a component of tobacco smoke and occurs naturally in coal tar, jasmine oil and orange-blossom oil. If released to the atmosphere, indole will mainly exist in the vapor phase based on a experimental vapor pressure of …

indole, a heterocyclic organic compound occurring in some flower oils, such as jasmine and orange blossom, in coal tar, and in fecal matter. It is used in perfumery and in making tryptophan, an essential amino acid, and indoleacetic acid (heteroauxin), a hormone that promotes the development of roots in plant cuttings.

In plants, indole is primarily known for its role in the synthesis of indole-3-acetic acid, one of the most important plant hormones. IAA regulates several critical plant functions, including cell elongation, root development, and response to environmental stimuli.

2025年1月10日 · Indole is a bicyclic compound, consisting of a six-membered benzene ring fused to a five-membered nitrogen-containing pyrrole ring. This structure imparts indole with a planar configuration, allowing for extensive conjugation across the rings.

2023年12月21日 · Indole is a signalling molecule produced both by bacteria and plants. In this review its signalling role between microbes and in particular in the human gut is discussed. Besides the natural roles, indole also has value for flavour and fragrance applications, for example, in food industry or perfumery.

2024年9月9日 · Indole is used to synthesize plant growth regulators such as indole-3-acetic acid and indole-3-butanoic acid. Indoline, a derivative of indole, is used in the synthesis of fungicidal and bactericidal plant protectives.

The indole nucleus is an important element of many natural and synthetic molecules with significant biological activity. This review covers some of the relevant and recent achievements in the biological, chemical and pharmacological activity of ...

2011年2月3日 · Indole is a planar bicyclic molecule in which the benzene ring is fused through 2 and 3 positions of N-containing pyrrole ring. Indole, having 10 π-electrons (8 from double bonds and 2 from lone pair of electrons on nitrogen) is said …

Indole is a versatile aromatic heterocycle used as a scaffold for the development of many drugs. Here we explore the different methodologies for its synthesis.
