Novel ruthenium(II) cyclopentadienyl thiosemicarbazone compounds with antiproliferative activity on pathogenic trypanosomatid parasites

Searching for new prospective antitrypanosomal agents, three novel Ru(II)-cyclopentadienyl compounds, [Ru(eta5-C5H5)(PPh3)L], with HL = bioactive 5-nitrofuryl containing thiosemicarbazones were synthesized and characterized in the solid state and in solution. The compounds were evaluated in vitro on the blood circulating trypomastigote form of Trypanosoma cruzi (Dm28c strain), the infective form of Trypanosoma brucei brucei (strain 427) and on J774 murine macrophages and human-derived EA.hy926 endothelial cells. The compounds were active against both parasites with IC50 values in the micromolar or submicromolar range. Interestingly, they are much more active on T. cruzi than previously developed Ru(II) classical and organometallic compounds with the same bioactive ligands. The new compounds showed moderate to very good selectivity towards the parasites in respect to mammalian cells. The global results point at [RuCp(PPh3)L2] (L2 = N-methyl derivative of 5-nitrofuryl containing thiosemicarbazone and Cp = cyclopentadienyl) as the most promising compound for further developments (IC50 T. cruzi = 0.41 muM; IC50 T. brucei brucei = 3.5 muM). Moreover, this compound shows excellent selectivity towards T. cruzi (SI > 49) and good selectivity towards T. brucei brucei (SI > 6). In order to get insight into the mechanism of antiparasitic action, the intracellular free radical production capacity of the new compounds was assessed by ESR. DMPO (5,5-dimethyl-1-pirroline-N-oxide) spin adducts related to the bioreduction of the complexes and to redox cycling processes were characterized. In addition, DNA competitive binding studies with ethidium bromide by fluorescence measurements showed that the compounds interact with this biomolecule.

Synthesis of NHC complexes by template controlled cyclization of beta-functionalized isocyanides

Starting from complexes of type [Ru(Cp)Cl(P-P)] (P-P = 2PPh3, 3a; P-P = 2PMe3, 3b: P-P = dppe, 3c; P-P = dppp, 3d) isocyanide complexes [Ru(Cp)(P-P)(CNR) 4a-4d (CNR = CN-CH2-CH2N 3, 1) and 7a-7d (CN-C6H4-2N3, 2) have been prepared. Reduction of the azido functions of the coordinated isocyanide ligands with Zn/NH4Cl/H2O in methanol leads to coordinated 2-amino functionalized isocyanides which cyclize to yield the complexes with a saturated NH,NH-stabilized NHC ligand 5a-5d or a benzannulated NH,NH-stabilized NHC ligand 8a-8d. The Zn/NH4Cl/H2O reduction method is of general applicability and allowed the generation of complex 11 bearing three saturated NH,NH-stabilized NHC ligands.

New ruthenium(II) complexes bearing N-heterocyclic carbenes

N-heterocyclic carbene complexes of ruthenium(II), [CpRu(L*)2Cl] (2) and [CpRu(CO)(L*)-Cl] (3) (Cp = eta5-C5H5; L* = l,3-dicyclohexyl-imidazolin-2-ylidene), have been obtained in high yields by reaction of [CpRu(PR2R?)2Cl] (R = R? = Ph, la; R = Ph, R? = 2-MeC6H4, 1b) and [CpRu(CO){PPh2(2-MeC6H4)}Cl] (1c), respectively, with the free carbene L*. The mixed dicarbene complex [CpRu(=CPh2)(L*)Cl] (4) is prepared from [CpRu(=CPh2){PPh2(2-MeC6H4-Cl] (1d) and an equimolar amount of L*, whereas subsequent reaction of 1d with L* leads to formation of 2, along with tetraphenylethene. The reaction of [Cp*Ru(PPh3)2Cl] (1e) with L* gives the pentamethylcyclopentadienyl derivative [Cp*Ru(PPh3)(L*)Cl] (5) (Cp* = eta5-C5Me5) by displacement of 1 equiv of PPh3 Complex 5 reacts in toluene with CO, pyridine (Py), and N2CHCO2Et, affording [Cp*Ru(CO)(L*)Cl] (6), [Cp*Ru(Py)(L*)Cl] (7), and the mixed dicarbene [Cp*Ru(=CHCO2Et)(L*)Cl] (8), which were isolated in high yields. The molecular structure of complex 6 has been determined by an X-ray investigation, and the carbene-ruthenium distance clearly indicates a single bond (2.0951(18) A). The N-heterocyclic carbene does not undergo substitution by other two-electron ligands.

Synthesis of a ruthenium(II) complex containing an [11]ane-P 2CNHC (NHC = Imidazolidin-2-ylidene) macrocycle

Reaction of [RuCl(Cp)(PPh3)2] with bis[di(2-fluorophenyl)phosphino]benzene, 3, yields complex [RuCl(Cp)(3)], [4]. The chloro ligand in [4] can be exchanged for the 2-azidoethyl isocyanide ligand 2, giving complex [Ru(Cp)(2)(3)]Cl, [5]Cl, which reacts with NH 4BF4 to give [5]BF4. The azido group of the coordinated isocyanide ligand in [5]C1 or [5]BF4 can be reduced with Zn/NH4Cl/H2O to give the complex with the 2-aminoethyl isocyanide ligand. This ligand is not stable but cyclizes by an intramolecular nucleophilic attack of the amino group at the isocyanide carbon atomto give an NH, NH-stabilized NHC ligand in complexes [6]X (X = Cl, [6]C1; X = 0.5 ZnCl 4, [6]2(ZnCl4); X = BF4, [6]BF 4). Deprotonation of the NH,NH-stabilized NHC ligands in cations of type [6]+ leads to an intramolecular nucleophilic attack of the amido nitrogen atoms at the fluorinated phenyl groups of the diphosphine ligand under formation of the complex with the facially coordinated macrocyclic [11]ane-P2CNHC ligand [1]X (X = Cl, [1]Cl; X = 0.5 ZnCl4, [1]2(ZnCl4); X = BF4, [1]BF4). Formation of the macrocycle is facilitated by the steric pressure excerted by the cyclopentadienyl ligand. The molecular structures of [4], [5]BF4, [6]BF4-CH2Cl2, and [1]Cl¡¤CH2Cl2¡¤0.5H2O have been determined by X-ray diffraction.
