Title

Development of ruthenium(II) complexes as topical antibiotics against methicillin resistant Staphylococcus aureus

Language

Abstract

A series of ruthenium(ii) bis(2,2′-bipyridyl) complexes containing N-phenyl-substituted diazafluorenes (Ru-C1, Ru-C6, Ru-C7 and Ru-F) was synthesized and their potential antibacterial activity against methicillin resistant Staphylococcus aureus (MRSA) was investigated. The Ru-C7 complex 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-1 and MBC = 100 μg mL-1). The Ru-C7 complex possessed much stronger antibacterial effects than the Ru-C6 complex (MIC, 25 μg mL-1, MBC, >100 μg mL-1). Both Ru-C6 and Ru-C7 complexes were also demonstrated to be biologically safe when tested on normal human skin keratinocytes. © 2014 The Royal Society of Chemistry.
