title: A revised structure of the antitumor drug elliptinium--amino(acid) adducts.
abstract: Using simple organic reactions and spectrometric techniques (nuclear magnetic resonance and mass spectrometry), we propose a revised structure of the adducts obtained through the H2O2-peroxidase oxidation of the antitumor drug ellipticinium and aliphatic amino(acid) compounds. These derivatives display an oxazole ring structure between the O(9)- and N(10)- atoms.
