reaction of bilirubins with aromatic diazonium salts in alcoholic solvents leads to an equimolar mixture of two types of products. One is the well-known 9-azopyrromethenone. The other is a yellow product (λmax ≈ 420 nm) identified as 9-alkoxymethylpyrromethenone, the alkoxy-substituent being derived from the solvent. Thus, reaction of the symmetrically substituted bilirubinsIIIα (1c) and XIIIα (1b) in

A new bilirubinoxidation end product (BOX) was isolated and characterized. The formation of the so-called Z-BOX C proceeds from bilirubin via propentdyopents as intermediates. This BOX was detected in pathological human bile samples using liquid chromatography/mass spectrometry and has potential relevance for liver dysfunction and cerebral vasospasms.
