Abstract
Three new water-soluble ruthenium porphyrin complexes have been prepared and characterized, one with a cationic ligand, Ru(TMPyP), and two others with anionic ligands, Ru(p–COOH-PP) and Ru(TPPS). These different complexes and their manganese and iron analogues were tested in vivo as potential antitumor agents with mice bearing P388 leukemia cells, but these complexes have no significant antitumor activity. The nuclease activity of Ru(TMPyP) and Ru(p–COOH-PP) was evaluated on supercoiled plasmid DNA after activation by a reducing agent (ascorbate) in the presence of air or by potassium monopersulfate. No significant activity was evidenced for these ruthenium complexes, in contrast with the already known nuclease activity of the manganese and iron derivatives of TMPyP.
