Diazaphenanthrenes (DAP), including 1) DAP with two N atoms in outer rings (phenanthrolines) and in adjacent rings (benzo[h]naphthyridines), 2) DAP with two N atoms in the outer ring and 3) DAP with two N atoms in the middle ring, i.e. benzo[c]cinnoline, and also triaza- and tetrazaphenanthrenes are of interest as well for their chemistry as for their pharmacological potential.
In this paper the literature has been reviewed with respect to the synthesis and properties of these ring systems. Since the literature on 1,10-phenanthroline and its complexes is very extensive, this subject requires rather an independent treatment and will not be included here.
