Biliatresone

Biliatresone is a natural toxin isolated from Dysphania glomulifera and D. littoralis. Biliatresone, a 1,2-diaryl-2-propenone class of isoflavonoid, produces extrahepatic biliary atresia in a zebrafish model^[1]. In Vitro:Biliatresone has a reduction in primary cilia and a dose-dependent decrease in visible microtubules, suggesting that Biliatresone decreases microtubule stability in primary neonatal mouse extrahepatic cholangiocytes^[1].
Biliatresone (2 µg/ml; for 24 hours) shows disruption of the spheroid lumen and abnormal cholangiocyte polarity in mouse cholangiocyte^[1].
In Vivo:Biliatresone exhibits toxicity at doses of 0.065-1.0 μg/mL with a marked reduction and the lethal dose of Biliatresone in a zebrafish assay is 1 μg/mL^[1].
Larvae treated at 5 dpf with low doses of biliatresone [0.0625 µg/ml (0.2 µM) and 0.125 µg/ml (0.4 µM)] shows only subtle gallbladder defects, whereas larvae treated with higher doses has pronounced morphological defects of the gallbladder and extrahepatic ducts^[1].
