  • Synthesis and properties of mesobilirubins XIIγ and XIIIγ and their mesobiliverdins
    作者:Portia Mahal G. Sabido、David A. Lightner

    The title pigments, with propionic acid groups displaced to the lactam end rings, were synthesized for the first time by the "1 + 2 + 1" approach, coupling two equivalents of a monopyrrole to a dipyrrylmethane (to give XII gamma), or the "2 + 2" approach, self-coupling two equivalents of a dipyrrinone (to give XIII gamma). Using the "1 + 2 + 1" approach, mesobilirubin III alpha was also prepared. Mesobilirubins XII gamma and XIII gamma are more polar than mesobilirubin III alpha and unlike III alpha cannot effectively engage the propionic acid groups in intramolecular hydrogen bonding to the dipyrrinone components. The new mesobilirubins give exciton coupled circular dichroism spectra in the presence of human serum albumin or quinine, with the XII gamma isomer exhibiting Cotton effect intensities nearly as strong as those from the III alpha isomer; whereas, the XIII gamma isomer exhibits far weaker intensities. Mesobilirubin III alpha requires glucuronidation for hepatobiliary elimination; whereas, XII gamma and XIII gamma do not, and they are excreted intact across the liver into bile. The corresponding biliverdins XII gamma and XIII gamma are reduced only slowly by biliverdin IX alpha reductase, in contrast to the fast reduction of the natural IX alpha isomer.
