Thiophenolato-bridged dinuclear arene ruthenium complexes: A new family of highly cytotoxic anticancer agents

New cationic diruthenium complexes of the type [(arene)2Ru 2(SPh)3]+, arene being C6H 6, p-iPrC6H4Me, C6Me 6, C6H5R, where R = (CH2) nOC(O)C6H4-p-O(CH2) 6CH3 or (CH2)nOC(O)CHCHC 6H4-p-OCH3 and n = 2 or 4, are obtained from the reaction of the corresponding precursor [(arene)RuCl2] 2 and thiophenol and isolated as their chloride salts. The complexes have been fully characterised by spectroscopic methods and the solid state structure of [(C6H6)2Ru2(SPh) 3]+, crystallised as the hexafluorophosphate salt, has been established by single crystal X-ray diffraction. The complexes are highly cytotoxic against human ovarian cancer cells (cell lines A2780 and A2780cisR), with the IC50 values being in the submicromolar range. In comparison the analogous trishydroxythiophenolato compounds [(arene)2Ru 2(S-p-C6H4OH)3]Cl (IC50 values around 100 muM) are much less cytotoxic. Thus, it would appear that the increased antiproliferative effect of the arene ruthenium complexes is due to the presence of the phenyl or toluyl substituents at the three thiolato bridges.

Effects of electronic mixing in ruthenium(II) Complexes with two equivalent acceptor ligands. Spectroscopic, electrochemical, and computational studies

The lowest energy metal to ligand charge transfer (MLCT) absorption bands found in ambient solutions of [Ru(NH3)4(Y-py) 2]2+ and [Ru(L)2(bpy)2]+ complexes (Y-py a pyridine ligand and (L)n a substituted acetonylacetonate, halide, am(m)ine, etc.) consist of two partly resolved absorption envelopes, MLCTlo and MLCThi. The lower energy absorption envelope, MLCTlo, in these spectra has the larger amplitude for the bis-(Y-py) complexes, but the smaller amplitude for the bis-bpy the complexes. Time-dependent density functional theory (TD-DFT) approaches have been used to model 14 bis-bpy, three bis-(Y-py), and three mono-bpy complexes. The modeling indicates that the lowest unoccupied molecular orbital (LUMO) of each bis-(Y-py) complex corresponds to the antisymmetric combination of individual Y-py acceptor orbitals and that the transition involving the highest occupied molecular orbital (HOMO) and LUMO (HOMO?LUMO) is the dominant contribution to MLCTlo in this class of complexes. The LUMO of each bis-bpy complex that contains a C2 symmetry axis also corresponds largely to the antisymmetric combination of individual ligand acceptor orbitals, while the LUMOs are more complex when there is no C2 axis; furthermore, the energy difference between the HOMO?LUMO and HOMO?LUMO+1 transitions is too small (<1000 cm -1) to resolve in the spectra of the bis-bpy complexes in ambient solutions. Relatively weak MLCTlo absorption contributions are found for all of the [Ru(L)2(bpy)2]m+ complexes examined, but they are experimentally best defined in the spectra of the (L)2 = X-acac complexes. TD-DFT modeling of the HOMO?LUMO transition of [Ru(L)4bpy]m+ complexes indicates that it is too weak to be detected and occurs at significantly lower energy (about 3000-5000 cm-1) than the observed MLCT absorptions. Since the chemical properties of MLCT excited states are generally correlated with the HOMO and/or LUMO properties of the complexes, such very weak HOMO?LUMO transitions can complicate the use of spectroscopic information in their assessment. As an example, it is observed that the correlation lines between the absorption energy maxima and the differences in ground state oxidation and reduction potentials (DeltaE1/2) have much smaller slopes for the bis-bpy than the mono-bpy complexes. However, the observed MLCTlo and the calculated HOMO?LUMO transitions of bis-bpy complexes correlate very similarly with DeltaE1/2 and this indicates that it is the low energy and small amplitude component of the lowest energy MLCT absorption band that is most appropriately correlated with excited state chemistry, not the absorption maximum as is often assumed. Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.category: ruthenium-catalysts, you can also check out more blogs about15746-57-3

B-substituted (arene)ruthenacarborane-sulfonium, -thioether and -mercaptan complexes: Mild single and double dealkylation and structural implications in the antipodal distance

Reactions of [RuCl2(eta6-arene)]2 (arene = benzene, p-cymene) with nido-[7-R-10-L-7,8-C2B9H 9]- in THF at room temperature for 3 d give the (arene)ruthenacarborane complexes closo-[3-Ru(eta6-arene)-1-R-8-L- 1,2-C2B9H9]+ {arene = benzene, R = H [L = Me2S (1a), THT (1b), EtPhS (1c)], R = Me [L = Me2S (2a)]; arene = p-cymene, R = H [L = Me2S (3a)]} and mercaptan closo-[3-Ru(eta6-arene)-1-R-8-HS-1,2-C2B 9H9] [arene = benzene, R = H (4), Me (5); arene = p-cymene, R = H (6)] in yields of 20-40% and 22-29%, respectively. The asymmetric ligand nido-[9-Me2S-7,8-C2B9H 10]- leads to the thioether complex closo-[3- Ru(eta6-benzene)-7-MeS-l,2-C2B9H 10] (8) in 34 % yield under the same reaction conditions. The crystal structure of 1a is described and compared with those of 4 and 8. The fully assigned 11B NMR spectroscopic data for a whole series of ruthenacarboranes having B-substituted sulfonium, thioether and mercaptan groups are presented. These data show a relation between antipodal cluster atom distances (antipodal distance) and antipodal effect (AE) in the crystal structures of these complexes and for other families of heteroboranes such as closo-[EB11H11] and closo-[EB9H9].

Influence of methionine?ruthenium complex on the fibril formation of human islet amyloid polypeptide

Abstract: The abnormal aggregation and deposition of human islet amyloid polypeptide (hIAPP) are implicated in the pathogeny of type 2 diabetes mellitus (T2DM). Many aromatic ring-containing Ru complexes inhibit the aggregation of hIAPP. A new Ru complex Ru(bipy)(met)2¡¤3H2O (1), where bipy is 2,2?-bipyridine and met is methionine, was synthesized and employed to resist the fibril formation of hIAPP and to promote the biocompatibility of metal complexes. Two polypyridyl Ru complexes, namely [Ru(bipy)3]Cl2(2) and Ru(bipy)2Cl2(3), were used for comparison. Results reveal that the three Ru complexes can inhibit hIAPP aggregation and depolymerize mature hIAPP fibrils. Interaction studies show that Ru complexes bind to hIAPP through metal coordination, hydrophobic interaction, and other intermolecular forces. The binding of the three compounds is spontaneous and exothermic. The compounds also rescue peptide-induced cytotoxicity to some extent. Similar to 3, the novel methionine?Ru complex 1 exhibits an enhanced inhibitory effect and binding affinity to hIAPP possibly because of the smaller steric hindrance and more profitable molecular configuration of 1 than those of 2. The newly designed amino acid?Ru complex may provide new insights into the treatment of T2DM and related amyloidosis diseases. Graphical abstract: Methionine?Ru complex effectively impedes the fibril formation of human islet amyloid polypeptide. [Figure not available: see fulltext.].

Stepwise functionalization of two alkyne moieties in a dialkynylphosphine complex leading to the formation of a bifunctionalized phosphine complex bearing a stereogenic center at phosphorus

Stepwise functionalization of the two alkyne moieties in a dialkynylphosphine complex has been studied. The two alkynyl groups underwent stepwise hydrophosphination and insertion to yield two different substituents on the stereogenic phosphorus. Coordination of the dialkynylphosphine ligand PPh(C?CCH3)2 to the ruthenium center generated the complex [Ru(eta6-benzene){PPh(C?CCH3) 2}Cl2]. Removal of one Cl atom by AgPF6 followed by coordination of HPPh2 to ruthenium promoted the hydrophosphination reaction with high stereoselectivity. The hydrophosphination products then underwent insertion into the Pd-C bond of a cyclopalladated complex to give a bimetallic complex bearing a stereogenic phosphorus center with expected substituents. The product contains also a tridentate ligand chelating to palladium, which is believed to have been generated through a proton exchange process aided by palladium. Furthermore, this complex exists as two interconvertable conformations in a ratio of 3:1. The structures of complexes were confirmed by X-ray crystallographic analyses and 2D ROESY NMR studies.
