Cytotoxicity of ruthenocene-containing β-diketones.
BACKGROUND Ferrocene-containing β-diketones and cisplatin, [(NH(3))(2)PtCl(2)], possess strong antineoplastic activity. No information is available regarding the anticancer activity of the corresponding ruthenocene complexes. This study examined the cytotoxicity of stable ruthenocene-containing β-diketones. The results were related to the cytotoxicity of cisplatin and the ease of ruthenium elec...
متن کاملArylazo derivatives of some fluorinated β-diketones and their metal complexes
Phenylazo and benzothiazolylazo derivatives of trifluoroacetylacetone andhexafluoroacetylacetone have been synthesized and characterized. Analytical and spectral datarevealed the existence of phenylazo derivatives in the intramolecularly hydrogen-bonded ketohydrazoneform while the benzothiazolylazo derivatives in the azo-enol form. The monobasicbidentate coordination of the phenylazo derivative...
متن کاملHigh-yielding oxidation of β-hydroxyketones to β-diketones using o-iodoxybenzoic acid.
The oxidation of β-hydroxyketones to β-diketones was systematically investigated. o-Iodoxybenzoic acid (IBX) was found to be efficient, operationally easy, and superior to other common oxidants. The reaction is suitable for milligram- to gram-scale oxidations.
متن کاملAzo mesogenic compounds
Series of elongated azo esters containing three rings with methyl moiety as one of the terminal carbon chain and various substituents R(R=H,CH3,OCH3,NO2,Cl) at the other end of the molecule have been isolated , and their structure were were characterized by H-NMR and IR as well as elemental analysis . The mesomorphic properties of these compounds were investigated via differential scanning calo...
متن کاملLuminescent organogels based on triphenylamine functionalized β-diketones and their difluoroboron complexes.
A series of new triphenylamine functionalized β-diketones 1–3 and their difluoroboron complexes 1B–3B were synthesized. They exhibited strong intramolecular charge transfer (ICT) emission. It was found that their self-assembling properties depended on the molecular structures. For example, compounds 1 and 1B, in which only one β-diketone or difluoroboron β-diketone unit was linked to triphenyla...
