A new molecule 4 [(GGH-DAE) 2DHQl associating the 1, 4, 5, 8-tetrahydroxyanthraquinone ring (DHQ) of the antitumor drug mitoxantrone (2), two diaminoethylene chains (DAE), and the metalchelating peptide Gly-Gly-His (GGH) has been synthesized. Such a molecule presents characteristics able to induce antitumor activity: compound 4 intercalates into DNA as measured by ATm, fluorescence quenching, and viscometry; ESR studies demonstrate ...
