M. Marder et al., 6,3'-DINITROFLAVONE, A NOVEL HIGH-AFFINITY LIGAND FOR THE BENZODIAZEPINE RECEPTOR WITH POTENT ANXIOLYTIC PROPERTIES, Bioorganic & medicinal chemistry letters, 5(22), 1995, pp. 2717-2720
6,3'-Dinitroflavone (2) and 6,4'-dinitroflavone (3), prepared by direc
t nitration of flavone (1), were found to be ligands for the benzodiaz
