Brief reduction of bilirubin with dilute sodium amalgam was shown to give chromogens containing both vinyl and ethylidene beta-substituents. Acid-catalysed rearrangement of these chromogens with bilirubin or mesobilirubin and subsequent dehydrogenation gave a range of new violins containing unconjugated ethylidene

Although phototherapy (PT) is a standard treatment for neonatal jaundice, no validated clinical methods for determination of bilirubin phototherapy products are available. Thus, the aim of our study was to establish a such method for clinical use. To achieve this

Aqueous pKa values of unconjugated bilirubin are important determinants of its solubility and transport. Published pKa data on an analog, mesobilirubin-XIIIalpha, studied by 13C-NMR in buffered solutions containing 27 and 64 vol% (C2H3)2SO because of low aqueous solubility of mesobilirubin
