Chemical Information
FooDB NameIsoimperatorin
DescriptionIsoimperatorin is a member of the class of compounds known as psoralens. Psoralens 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. Isoimperatorin is practically insoluble (in water) and an extremely weak basic (essentially neutral) compound (based on its pKa). Isoimperatorin can be found in a number of food items such as parsley, lime, wild celery, and parsnip, which makes isoimperatorin a potential biomarker for the consumption of these food products. Isoimperatorin is a non-carcinogenic (not listed by IARC) potentially toxic compound. If the compound has been ingested, rapid gastric lavage should be performed using 5% sodium bicarbonate. For skin contact, the skin should be washed with soap and water. If the compound has entered the eyes, they should be washed with large quantities of isotonic saline or water. In serious cases, atropine and/or pralidoxime should be administered. Anti-cholinergic drugs work to counteract the effects of excess acetylcholine and reactivate AChE. Atropine can be used as an antidote in conjunction with pralidoxime or other pyridinium oximes (such as trimedoxime or obidoxime), though the use of '-oximes' has been found to be of no benefit, or possibly harmful, in at least two meta-analyses. Atropine is a muscarinic antagonist, and thus blocks the action of acetylcholine peripherally (T3DB).
