SYNTHESIS AND CHARACTERIZATION OF NITROSYL COMPLEXES WITH ANTIBACTERIAL ACTION AGAINST Pseudomonas aeruginosa. The compounds nitrosyl cis-[Ru(bpy)(phen)TU(NO)](PF 6 ) 3 (compound 1) and cis-[Ru(bpy) (phen)(4-N-Imd)(NO)](PF 6 ) 3 (compound 2) (bpy = 2,2'-bipyridine, phen = 1,10'-phenanthroline, TU = thiourea and 4-N-Imd = 4-nitroimidazole) were synthesized and characterized by UV-visible, infrared spectroscopies and electrochemical techniques. In the study of the reactivity it was possible to verify the nitric oxide labilization by square wave voltammetry and a photochemical upon blue light irradiation. This feature is very important for a potential application in phototherapy. Additionally, the antibacterial activity of the nitrosyl complexes was tested against gram-negative bacteria Pseudomonas aeruginosa. Thus, it has been observed that the complexes are capable of inhibiting the growth of such microorganisms.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
