文摘

The electronic properties of a new set of cytotoxic 2-amino-naphtho[2,3-b]furan-4,9-dione derivatives (1鈭?b>8) are evaluated. The electron delocalization of these compounds is described by means of their redox potentials and solvatochromic properties. The large solvatochromism of their intramolecular electron transfer band is analyzed using the linear solvation energy relationship method. In addition, this method determined the importance of the molecular environment, quantifying the interactions that compounds (1鈭?b>8) establish with their surrounding media, with the capacity of acting as hydrogen-bond acceptors (HBA) and hydrogen-bond donors (HBD) and the dipolarity/polarizability being the most significant ones. As a result, a relationship between the electronic and the cytotoxic properties of these compounds is proposed.
