Terpeno-phenolic compounds

Tetrahydrocannabinol (THC) is a cannabinoid found in cannabis. It is the principal psychoactive constituent of Cannabis and one of at least 113 total cannabinoids identified on the plant. Although the chemical formula for THC (C21H30O2) describes multiple isomers, the term THC usually refers to the delta-9-THC isomer with chemical name '(−)-trans-Δ9-tetrahydrocannabinol'. It is a colorless oil.

Lapachol is a natural phenolic compound isolated from the bark of the lapacho tree. This tree is known botanically as Handroanthus impetiginosus, but was formerly known by various other botanical names such as Tabebuia avellanedae. Lapachol is also found in other species of Handroanthus.

Tetrahydrocannabivarin (THCV, THV, O-4394, GWP42004) is a homologue of tetrahydrocannabinol (THC) having a propyl (3-carbon) side chain instead of pentyl (5-carbon), making it non-psychoactive in lower doses. It has been shown to exhibit neuroprotective activity, appetite suppression, glycemic control and reduced side effects compared to THC, making it a potential treatment for management of obesity and diabetes. THCV was studied by Roger Adams as early as 1942.

Alkannin is a natural dye that is obtained from the extracts of the plant dyer's alkanet (Alkanna tinctoria) which is found in the Mediterranean region. The dye is used as a food coloring and in cosmetics; within the European E number schedule, it is numbered E103. It is used as a red-brown food additive in regions such as Australia. Alkannin is deep red in an acid and blue in an alkaline environment. The chemical structure as a naphthoquinone derivative was first determined by Hans Brockmann in 1936. The (R)-enantiomer of alkannin is known as shikonin, and the racemic mixture of the two is kn

Bakuchiol is a meroterpenoid (a chemical compound having a partial terpenoid structure) in the class terpenophenol.

Bergamottin (5-geranoxypsoralen) is a natural furanocoumarin found in the pulp of pomelos and grapefruits. It is also found in the peel and pulp of the bergamot orange, from which it was first isolated and from which its name is derived.

Cannabigerol (CBG) is a non-psychoactive cannabinoid and minor constituent of cannabis. It is one of more than 120identified cannabinoids found in the plant genus Cannabis. The compound is the decarboxylated form of cannabigerolic acid (CBGA), the parent molecule from which other cannabinoids are biosynthesized.

Auraptene is a natural bioactive monoterpene coumarin ether. It was first isolated from members of the genus Citrus.

Imperatorin is a furocoumarin and a phytochemical that has been isolated from Urena lobata L. (Malvaceae), Angelica archangelica, Angelica dahurica, Glehnia littoralis, Saposhnikovia divaricata, Cnidium monnieri, Incarvillea younghusbandii, and Zanthoxylum americanum mill. It is biosynthesized from umbelliferone, a coumarin derivative.

Humulone (α-lupulic acid), a vinylogous type of organic acid, is a bitter-tasting chemical compound found in the resin of mature hops (Humulus lupulus). Humulone is a prevalent member of the class of compounds known as alpha acids, which collectively give hopped beer its characteristic bitter flavor.

Marmesin (nodakenetin) is a chemical compound precursor in psoralen and linear furanocoumarins biosynthesis.

'''6',7'-Dihydroxybergamottin''' is a natural furanocoumarin found in pomelos, grapefruits, and sour oranges, in both the peel and the pulp. Along with the chemically related compound bergamottin, it is believed to be responsible for a number of grapefruit–drug interactions, in which the consumption of citrus containing one or both of these compounds (especially grapefruit) affects the metabolism of a variety of pharmaceutical drugs.

Ferujol is a compound in the coumarin family, isolated from Ferula jaeschkeana.

Ascofuranone is an antibiotic produced by various ascomycete fungi including Acremonium sclerotigenum that inhibits the Trypanosoma brucei alternative oxidase and is a lead compound in efforts to produce other drugs targeting this enzyme for the treatment of sleeping sickness. The compound is effective both in vitro cell culture and in infections in mice.
