Antineoplastic and antibacterial activity of some mononuclear Ru(II) complexes.

摘要

These ligands (L) show a bidentate behavior, forming octahedral ruthenium complexes. The title complexes were subjected to in-vivo anticancer activity tests against a transplantable murine tumor cell line, Ehrlich's Ascitic Carcinoma (EAC) and in-vitro antibacterial activity against several Gram positive and Gram negative bacterial strains. [Ru(bpy)2(ihqs)]Cl2 and [Ru(bpy)2 (hc)]Cl2 (where bpy = 2,2'-bipyridine, ihqs = 7-iodo-8hydroxy quinoline-5-sulphonic acid and hc = 3-hydroxy coumarin) showed promising antitumor activity. Treatment with these complexes prolonged the life span of EAC bearing mice as well as decreased their tumor volume and viable ascitic cell count. All the tested complexes exhibited mild to moderate antibacterial activity.
