OXIDATIVE DEGRADATION OF BILIVERDIN AND BILIRUBIN ESTERS IN PRESENCE OF SILVER NITRATE

摘要

Treatment of biliverdin IXα dimethyl ester(2)with silver nitratein alkaline solution gave two violin-like tripyrrione carbaldehydes,one de-graded at C15-C16,other at C4-C5.Biliverdin IXα(1),bilirubin IXα(3)andits dimethyl ester(4)gave the same results.
