The interaction of two gold(III) complexes [Au(phen)Cl2](Cl) (1) and [Au(pdon)Cl2](Cl) (2) with calf thymus-DNA (CT-DNA) has been investigated by absorption and fluorescence emission. Both complexes 1 and 2 show medium interaction ability with CT–DNA with the intrinsic binding constants Kb of 4.98 × 105 and 1.98 × 105 M–1 at room temperature, respectively, which is the same as earlier reports for typical classical intercalators. Moreover, complex 1 demonstrates a better antitumor effect on the tested cancer cells.
