All solvents were of analytical grade and used without further purification (except the solutions used for the DNA cleavage assay, vide infra). [RhCp*(μ-Cl)Cl]₂, [Ru(η⁶-p-cymene)(μ-Cl)Cl]₂, 5-chloro-8-hydroxyquinoline, D-proline, D-homoproline, aqueous formaldehyde (30% (v/v)), pic, phen, KNO₃, HNO₃, KOH, n-octanol, CD₃OD, D₂O, doxorubicin, EB, HSA (A8763, essentially globulin free), ct-DNA, DG, 4,4-dimethyl-4-silapentane-1-sulfonic acid (DSS) were Sigma-Aldrich (St. Louis, MO, USA) products and were used without further purification. FHA was purchased from GenScript (Piscataway, NJ, USA). NaH₂PO₄, Na₂HPO₄, KH₂PO₄, KCl, NaCl, diethyl-ether, n-hexane, ethanol, ethyl acetate and methanol were purchased from Molar Chemicals (Halásztelek, Hungary) or Reanal (Budapest, Hungary). [RuCym(HQCl-L-Pro)Cl]Cl and [RhCp*(HQCl-L-Pro)Cl]Cl were used in some cases due to comparative reasons, and their preparation and characterization were reported in our previous work [25 (link)].
