potentiometric, spectrophotometric and spectrofluorimetric techniques. The equilibria and kinetics of the binding process of D and [ZnD] to calfthymusDNA have been investigated at I=0.11 M (NaCl) and 298.1 K by using spectroscopic methods and the stopped-flow technique. Static measurements show biphasic behaviour for both D-DNA and [ZnD]-DNA systems; this reveals the occurrence of two different binding processes

A new synthesis of 3,6-diamino-9-anilinoacridines, via reduction of the corresponding diazides, gives much higher yields than traditional methods. Within the subset of 3,6-diamino-9-anilinoacridines, there was considerable tolerance to substitution at the 1'-anilino position. In a sharp divergence with structure-activity relationships for high mammalian cell toxicity and anticancer effects, derivatives
