DescriptionHeratomin is a furocoumarin. Furocoumarins, are phototoxic and photocarcinogenic. They intercalate DNA and photochemically induce mutations. Furocoumarins are botanical phytoalexins found to varying extents in a variety of vegetables and fruits, notably citrus fruits. The levels of furocoumarins present in our diets, while normally well below that causing evident acute phototoxicity, do cause pharmacologically relevant drug interactions. Some are particularly active against cytochrome P450s. For example, in humans, bergamottin and dihydroxybergamottin are responsible for the 'grapefruit juice effect', in which these furanocoumarins affect the metabolism of certain drugs.

Toxicity Profile
Route of ExposureNot Available
Mechanism of ToxicityThe mechanism of action many furocoumarins is based on their ability to form photoadducts with DNA and other cellular components such as RNA, proteins, and several proteins found in the membrane such as phospholipases A2 and C, Ca-dependent and cAMPdependent protein-kinase and epidermal growth factor. Furocoumarins intercalate between base pairs of DNA and after ultraviolet-A irradiation, giving cycloadducts. Heratomin is aloso an inhibitor of insect cytochromes P450. (5)

Carcinogenicity (IARC Classification)Not listed by IARC. IARC has assessed other furocoumarins, classifying 8-methoxypsoralen as carcinogenic to humans (Group 1), 5-methoxypsoralen as possibly carcinogenic to humans (Group 2A), and certain other furocoumarins as not being classifiable as to their carcinogenicity to humans (Group 3). (4)
Uses/SourcesNot Available
Minimum Risk LevelNot Available
Health EffectsThe furocoumarin 8-methoxypsoralen is carcinogenic to humans, and possibly 5-methoxypsoralen as well (4). There is some evidence from mouse studies that other furocoumarins are carcinogenic when combined with exposure to UVA radiation (1). The SKLM regards the additional risk of skin cancer arising from the consumption of typical quantities of furocoumarin-containing foods, which remain significantly below the range of phototoxic doses, as insignificant. However, the consumption of phototoxic quantities cannot be ruled out for certain foods, particularly celery and parsnips, that may lead to significant increases in furocoumarin concentrations, depending on the storage, processing and production conditions. (6) Furocoumarin photochemotherapy is known to induce a number of side-effects including erythema, edema, hyperpigmentation, and premature aging of skin. All photobiological effects of furocoumarins result from their photochemical reactions. Because many dietary or water soluble furocoumarins are strong inhibitors of cytochrome P450s, they will also cause adverse drug reactions when taken with other drugs.
