Common NamePsoralen
DescriptionPsoralen, also known as ficusin or manaderm, belongs to the class of organic compounds known as psoralens. These are organic compounds containing a psoralen moiety, which consists of a furan fused to a chromenone to for 7H-furo[3,2-g]chromen-7-one. 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. All photobiological effects of furocoumarins result from their photochemical reactions. Psoralen is an extremely weak basic (essentially neutral) compound (based on its pKa). Outside of the human body, Psoralen is found, on average, in the highest concentration within a few different foods, such as figs, parsley, and parsnips and in a lower concentration in lovages, carrots, and wild carrots. Psoralen has also been detected, but not quantified in, several different foods, such as radish (var.), Elliott's blueberries, squashberries, pepper (c. Annuum), and gram beans. This could make psoralen a potential biomarker for the consumption of these foods. Psoralen is a potentially toxic compound. Psoralen is a significant mutagen and is used for this purpose in molecular biology research. 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). The 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. In case of contact with eyes, rinse immediately with plenty of water and seek medical advice. The Psoralen 8-methoxypsoralen is carcinogenic to humans, and possibly 5-methoxypsoralen as well (L135).
