The in vivo oxidation of heme yields bilirubin which is further degraded to the bilirubin oxidation end products (BOXes) that are biologically highly active. To study the mode of action and fate of (Z)-2-(4-methyl-5-oxo-3-vinyl-1,5-dihydro-2H-pyrrol-2-yli
In vivo and in vitro identification of Z -BOX C-a new bilirubin oxidation end product

A new bilirubin oxidation 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.
Isolation and Identification of Intermediates of the Oxidative Bilirubin Degradation

Four endogenous products of oxidative bilirubin degradation were isolated and fully characterized. The constitutional isomers belong to the propentdyopents (PDPs). Their structures and further oxidative transformations to biologically active bilirubin oxi
Total synthesis and detection of the bilirubin oxidation product (Z)-2-(3-ethenyl-4-methyl-5-oxo-1,5-dihydro-2H-pyrrol-2-ylidene)ethanamide (Z-BOX A)

The selective total synthesis of the pure Z-isomer of BOX A (8a), a product of oxidative heme degradation with significant physiological impact, was achieved in four to six steps starting from 3-bromo-4-methylfuran-2,5-dione (1). Z-BOX A forms a strong hydrogen bridge framework in the crystalline state. LC-MS techniques allow identification and characterization of isomeric forms of BOX A.
