The carborane-selenol [(B10H11C2)SeH] has been isolated and its anion employed as a ligand. Reaction of the ligand with [AuClL] (L = PPh3, AsPh3) (1 : 1 molar ratio) or PPN[AuCl2] (PPN = N(PPh3)2) (2 : 1 molar ratio) affords the mononuclear compounds [Au(SeC2 B10H11)L] or PPN[Au(SeC2B10H11)2], respectively. Dinuclear derivatives [Au2(SeC2B10 H11)2(mu-PP)] (PP = 1,1?-bis(diphenylphosphino) ferrocene (dppf), 1,2-bis(diphenylphosphino)ethane (dppe)) are synthesised by reaction of the ligand with [Au2Cl2(mu-PP)] or by reaction of [Au(SeC2B10H11)-(AsPh3)] with the bidentate ligand. The selenolate acts in a bridging mode in [M2(mu-SeC2B10H11) (PPh3)2]X2 (M = Au, X = ClO4; M = Ag, X = TfO), obtained by treatment of the ligand with [O{Au(PPh3)}3]ClO4 or by reaction with [Ag(TfO)(PPh3)] in 1 : 2 molar ratio, respectively. The crystal structure of [Au(SeC2B10H11)(PPh3)] has been determined by X-ray diffraction studies.

A series of new heterometallic gold(I) thiolates containing ferrocenyl-phoshines were synthesized. Their antimicrobial properties were studied and compared to that of FDA-approved drug, auranofin (Ridaura), prescribed for the treatment of rheumatoid arthritis. MIC in the order of one digit micromolar were found for most of the compounds against Gram-positive bacteria Staphylococcus aureus and CA MRSA strains US300 and US400. Remarkably, auranofin inhibited S. aureus, US300 and US400 in the order of 150-300 nM. This is the first time that the potent inhibitory effect of auranofin on MRSA strains has been described. The effects of a selected heterometallic compound and auranofin were also studied in a non-tumorigenic human embryonic kidney cell line (HEK-293).

An efficient approach to chloro(organophosphine) gold(i) complexes for the synthesis of auranofin

A practical and efficient synthesis of chloro(organophosphine) gold(i) complexes is reported. Employment of 4,4?-dihydroxydiphenyl sulfide as a safe and non-irritating reductant is highlighted for the generation of Au(i)-S intermediates, which could be trapped by mono- and bidentate phosphine ligands to provide organophosphine gold(i) complexes. The utility of the present method is further demonstrated by the synthesis of the antiarthritic drug auranofin.

Abstract: Reaction of Na2[PdCl4] with two equivalents of 4,5-benzo-3H-1,2-dithiole-3-thione (btt) affords cis-[PdCl2(kappa1-btt)2] (1), which provides a convenient entry into mixed-ligand btt complexes. Addition of one equivalent of a range of diamines or diphosphines gives the salts [Pd(kappa1-btt)2(kappa2-diamine)]Cl2 (2a?d) (diamine = en, dap, bipy, phen) and [Pd(btt)2(kappa2-diphosphine)]Cl2 (3a?c) (diphosphine = dppe, dppp, dppf) in good yields. In contrast, two equivalents of dppm result in [Pd(kappa1-btt)2(kappa1-dppm)2]Cl2 (4), where the diphosphine binds in a monodentate fashion. Two equivalents of PPh3 result in a mixture of cis- and trans-isomers of [Pd(kappa1-btt)2(PPh3)2]Cl2 (5a?b) (ca. 1:5 ratio); the pure trans-isomer 5b was isolated by ion-exchange chromatography. The cis-isomer 5a could be synthesized independently from the reaction of cis-[PdCl2(PPh3)2] with two equivalents of btt. In all of these complexes, the btt ligand binds in a monodentate manner through the exocyclic thione sulfur. The anti-tumor activities of representative examples, cis-[PdCl2(kappa1-btt)2] (1), cis-[Pd(kappa1-btt)2(kappa1-dppm)2]Cl2 (4) and cis-[Pd(kappa1-btt)2(PPh3)2] (5a), were evaluated by cell proliferation assays and phase-contrast microscopy against prostate cancer cell lines PC3, DU145 and LNCaP, with complexes 1 and 4 showing potent anti-proliferative effects (TGI values of 19.2 and 21.1?mug/mL, respectively) against LnCaP cells.

[PPh4]2[M(C2N2 S2)2] (M = Pt, Pd) and [Pt(C2N2S2) (PR3)2] (PR3 = PMe2Ph, PPh3) and [Pt(C2N2S2)(PP)] (PP = dppe, dppm, dppf) were all obtained by the reaction of the appropriate metal halide containing complex with potassium cyanodithioimidocarbonate. The dimeric cyanodithioimidocarbonate complexes [{Pt(C2N2S2) (PR3)}2] (PR3 = PMe2Ph), [M{(C2N2 S2)(eta5-C5Me5)}2] (M = Rh, Ir) and [{Ru(C2N2S2) (eta6-p-MeC6H41Pr)}2] have been synthesised from the appropriate transition metal dimer starting material. The cyanodithioimidocarbonate ligand is S,S and bidentate in the monomeric complexes with the terminal CN group being approximately coplanar with the CS2 group and trigonal at nitrogen thus reducing the planar symmetry of the ligand. In the dimeric compound one of the sulfur atoms bridges two metal atoms with the core exhibiting a cubane-like geometry.
