Antimicrobial activity of the ionic liquids triethanolamine acetate and diethanolamine chloride, and their corresponding Pd(II) complexes

Abstract

The antimicrobial activity of the ionic liquids triethanolamine acetate [TEA][HOAc] and diethanolamine chloride [HDEA][Cl], as well as of their Pd(II) complexes trans-dichlorobis(triethanolamine-N)palladium(II) (trans-[PdCl 2(TEA) 2]) and diethanolammonium-tetrachloridopalladate(II) ([HDEA] 2[PdCl 4]), is presented. The investigated compounds showed low antibacterial activity. Better results were for antifungal activity. [TEA][HOAc] exhibited better activity than corresponding complex. Aspergillus species were especially sensitive to [HDEA] 2[PdCl 4]. The activity of this complex against A. restrictus, A. fumigatus was up to ten times higher than the activity of positive control, fluconazole. © 2012 Elsevier B.V. All rights reserved.
