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

The aims of this study were to produce mesobiliverdin IXα, an analog of anti-inflammatory biliverdin IXα, and to test its ability to enhance rat pancreatic islet yield for allograft transplantation into diabetic recipients. Mesobiliverdin IXα was synthesized from phycocyanobilin derived

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
