A series of (C^S)-cyclometallated Au(III) cationic complexes of general formula [Au(dppta)(dtc)] + , [Au(dppta)(azmtd)] + and [Au(dppta)(azc)Cl] + (dppta = N,N-diisopropyl-P,P-diphenylphosphinothioic amide-κ 2 C,S; dtc = dithiocarbamate-κ 2 S,S'; azc = azolium-2-dithiocarboxylate-κ 1 S; azmdt = azol(in)ium-2-(methoxy)methanedithiol-κ 2 S,S') were synthetized and tested against a panel of bacterial strains belonging to different Gram-positive and Gram-negative species of the ESKAPE group of pathogens. Among the tested compounds, complex 4c had the higher Therapeutic Index (TI) against multidrug resistant strains of S. aureus, S. epidermidis and A. baumannii, showing a more favourable cytotoxicity profile than the reference gold metalloantibiotic Auranofin. © 2024 xxxxxxxx.
