In a patent, introducing its new discovery.

Half sandwich ruthenium, rhodium and iridium complexes containing pyridyl chalcone analogues (L1 and L2) are prepared by the reaction of [(arene)M(mu-Cl)Cl]2 (arene = benzene, p-cymene, Cp*) and (M = Ru, Rh/Ir)] with L1 and L2 in 1:2 (M:L) ratio. Eight neutral mononuclear complexes (1?8) were obtained and characterized using FT-IR, 1H NMR, 13C NMR, ESI mass and UV?Vis spectroscopic methods. The molecular structures of complexes 2, 4, 5 and 7 are established by single crystal X-ray diffraction studies. Antibacterial studies were tested against three strains of bacterial microorganisms Staphylococcus aureus (gram +ve), Klebsiella pneumoniae (gram ?ve) and Escherichia coli (gram ?ve). Further the cytotoxicity study of the pyridyl chalcone derivatives and their complexes were evaluated against the human colorectal cancer cell lines HT-29, HCT-116 p53+/+, HCT-116 p53?/? and ARPE-19 (non-cancer retinal epithelium).

Application of 37366-09-9, An article , which mentions 37366-09-9, molecular formula is C12H12Cl4Ru2. The compound – Dichloro(benzene)ruthenium(II) dimer played an important role in people’s production and life.

In search for antitumor metal-based drugs that would mitigate the severe side-effects of cisplatin, Ru(II) complexes are gaining increasing recent interest. In this work, we report on the synthesis, characterization (1H- and 13C-NMR, FT-IR), and cytotoxicity studies of two new half-sandwich organometallic Ru(II) complexes of the general formula [Ru(eta6-arene)(XY)Cl](PF6) where arene = benzene or toluene and XY = bidentates: dipyrido[3,2-a:2?,3?-c]phenazine (dppz) or 2-(9-anthryl)-1H-imidazo[4,5-f][1,10]phenanthroline (aip), which are bound to Ru(II) via two phenanthroline-N atoms in a characteristic ?piano-stool? configuration of Ru(II)-arene complexes?as confirmed by vibrational and NMR spectra. In addition, cytotoxic studies were performed for similar half-sandwich organometallic [Ru(eta6-p-cymene)(Me2dppz)Cl]PF6 complex (Me2dppz = 11,12-dimethyl-dipyrido[3,2-a:2?,3?-c]phenazine). This study is complemented with elaborate modeling with density functional theory (DFT) calculations, which provided insight into reactive sites of Ru(II) structures, further detailed by molecular docking on the B-DNA dodecamer, which identified binding sites and affinities: most pronounced for the [Ru(eta6-benzene)(aip)Cl](PF6) in both A-T and G-C regions of the DNA minor groove. Cytotoxic activity was probed versus tumor cell lines B16, C6, and U251 (B16 mouse melanoma, C6 rat glioma, U251 human glioblastoma) and non-tumor cell line HACAT (HACAT normal human keratinocytes).

New benzene ruthenium(II) aroylhydrazone complexes of general molecular formula [Ru(eta6-C6H6)Cl(L)] (where L = aroylhydrazone ligand) have been synthesized from the reaction of the precursor [Ru(eta6-C6H6)(mu-Cl)Cl]2and aroylhydrazone ligands. The composition of the complexes has been accomplished by elemental analysis and spectral methods (FT-IR, UV-Vis,1H NMR). The molecular structure of complex 4 has been established by single-crystal X-ray structure analysis shows that the aroylhydrazone ligands are coordinated to ruthenium as a bidentate N, O donor and a typical piano stool geometry was observed around ruthenium(II) metal center. All the complexes exhibit two consecutive irreversible oxidations in the potential range +0.74 to +1.17 V (RuII/RuIII;RuIII/RuIV) Vs calomel electrode. Further, in vitro anticancer activity of complexes 1-4 on human breast cancer cell line (MCF-7), human cervical cancer cell line (HeLa) and non-cancerous NIH-3T3 cell line exhibit moderate to excellent cytotoxic activity. It is also evident from IC50values that the complexes are more potent against MCF-7 cells than cisplatin. The superior activity of the complex 4 assumes that presence of electron donating methoxy substituent which makes the ring more reactive. Further, the morphological changes during cell death were investigated by Acridine Orange-Ethidium Bromide (AO-EB) and DAPI staining techniques, which confirm the complex 4 induces cell death only through apoptosis.

The whole “pybox” and dice: Highly enantioselective amination reactions of both allylic and benzylic C-H bonds are catalyzed by cationic ruthenium(II)-pybox complexes (see structure). A novel mode of stereocontrol, which is induced by the versatile pybox ligand, is proposed to account for the excellent enantioselectivity in these reactions.
