including multidrug resistant strains. It is, however, inactive toward Gram-negative bacteria, for which we are in dire need of new therapies. In this work, 40 auranofin analogues were synthesized by varying the structures of the thiol and phosphine ligands, and their activities were tested against ESKAPEpathogens. The study identified compounds that exhibited bacterial inhibition (MIC) and killing

We present new insights into the ligand strength of the metalloid [Ge9(Hyp)3]− cluster (Hyp=Si(SiMe3)3) alongside novel neutral Ge9clusters of the composition R3PAuGe9(Hyp)3 (R=Et, nPr, iPr, nBu, tBu, Cy). These clusters are synthesized in good yields from KGe9(Hyp)3 and R3PAuCl. Further experiments with these new clusters show that the ligand strength of [Ge9(Hyp)3]− is in between aryl and alkyl phosphines

Intramolecular aurophilic interaction (3.63 Å ) complemented by hydrogen bonding dictates the non-oligomeric structure of 1,3-bis(diphenylphosphine)propane(9H-purin- 6-ylamin-9-ate)gold(I) (7). Dimeric aurophilic interactions appear in the structure of (tributylphosphine)( 9H-purin-9-ate)gold(I) (11) (3.2311(7)
