Biliatresone

Biliatresone is an example of a very rare type of a naturally occurring isoflavonoid-related 1,2-diaryl-2-propenone found in Dysphania glomulifera and D. littoralis.[1][2][3] It has been found to cause extrahepatic biliary atresia in a zebrafish model. The enone moiety of biliatresone is particularly reactive, being enhanced by the methylenedioxy, methoxy and hydroxy groups,[4] and undergoes ready Michael addition of water and methanol.
