Abstract

A series of ruthenium(ii) bis(2,2′-bipyridyl) complexes containing N-phenyl-substituted diazafluorenes (Ru-C1, Ru-C6, Ru-C7and Ru-F) was synthesized and their potential antibacterial activity against methicillin resistant Staphylococcus aureus (MRSA) was investigated. The Ru-C7complex showed significant improvement in both minimum inhibitory concentration (MIC, 6.25 μg mL-1) and minimum bactericidal concentration (MBC, 25 μg mL-1) towards MRSA when compared with those of methicillin (positive control) (MIC = 25 μg mL-1and MBC = 100 μg mL-1). The Ru-C7complex possessed much stronger antibacterial effects than the Ru-C6complex (MIC, 25 μg mL-1, MBC, >100 μg mL-1). Both Ru-C6and Ru-C7complexes were also demonstrated to be biologically safe when tested on normal human skin keratinocytes.
