The DNA binding properties of the Au(I)-containing antiarthritic drug Ridaura and related Au(I) complexes have been investigated. Absorption and circular dichroism spectroscopy show that if the gold ion possesses an easily displaced ligand,e.g.,Cl-or Br-,Au(I) is capable of interacting, in a nondenaturing fashion, with calf thymus DNA. Absorption studies with the four DNA nucleosides suggest that guanine and cytosine bases are important in the Au(I)DNA interaction.
