Anticancer study of heterobimetallic platinum(II)-ruthenium(II) and platinum(II)-rhodium(III) complexes with bridging dithiooxamide ligand
2019
Abstract Three heterobimetallic platinum (II)/ruthenium (II) and platinum (II)/rhodium (III) complexes, A: Pt{S–S2C2(NR)2H}{μ-S2C2(NR)2}-[Ru (p-cymene)Cl], R = isoamyl; B: Pt{S–S2C2(NR)2H}{μ-S2C2(NR)2}[Rh (phpy)2], R = isoamyl; C: [Pt{S–S2C2(NR)2H}{μ-S2C2(NR)2}-[Rh(C5Me5)Cl]], R = benzyl, were prepared from mononuclear complexes 1 and 2, 1: [Pt (H-isoamyl2DTO)2]; 2: [Pt (H-benzyl2DTO)2], DTO = dithiooxamide, by reaction of 1 or 2 with the corresponding chlorido-bridged dimers, [Rh(C5Me5)Cl (μ-Cl)]2, [Ru (p-cymene)Cl (μ-Cl)]2 or [Rh (phpy)2 (μ-Cl)]2, and then evaluated as anticancer agents for the inhibition of the three proteolytic activities of human 20S proteasome, one of the main target …
Alkane dehydrogenation on defective BN quasi-molecular nanoflakes: DFT studies
2020
Lower alkanes are feedstocks readily available but relatively inert. The con- version of low cost alkanes to industrially relevant alkenes is usually carried out on metal-based heterogeneous catalysts. Considering both the cost and the potential harmfulness of the metal involved in the dehydrogenation cat- alysts (typically, platinum or chromium), the study of metal-free processes represents an important challenge for the industrial chemistry in order to address more sustainable protocols and different routes either to activate or transform alkanes. Framed in this context, it was investigated, using a den- sity functional theory approach, the potential dehydrogenation activity of de- fectiv…
N-Glycosylamines of 4,6-O-ethylidene-alpha-D-glucopyranose: synthesis, characterisation and structure of CO2H, Cl and F ortho-substituted phenyl deri…
2000
A saccharide based ligand suitable for metal binding (HLCOOH) has been synthesized using 4,6-O-ethylidene-alpha-D-glucopyranose (4,6-O-EGP) and anthranilic acid. A few analogous glycosylamines with chloro and fluoro ortho substitutions have also been synthesized and characterised. Complexes of HLCOOH with Na+, K+, Mg2+, Ca2+, Ba2+, Cd2+ and Hg2+ have been isolated and characterised fully. The crystal structures of 4,6-O-EGP, the chloro analogue of HLCOOH and the K+ complex of L-COOH are established. The anomeric nature, orientation of the binding core and the co-ordination aspects of K+ have been derived from these structures.
Chlorido(dimethyl sulfoxide)(pyridine-2-thiolato N-oxide-κ2S,O)platinum(II)
2008
The asymmetric unit of the title compound, [Pt(C5H4NOS)Cl(C2H6OS)], contains two independent complex molecules having similar geometries. Each PtII atom is four-coordinated in a distorted square-planar geometry by S and O atoms of one pyridine N-oxide ligand, the S atom of one dimethyl sulfoxide molecule and one terminal Cl− ion. The molecules are linked into a three-dimensional framework by C—H...O and C—H...Cl hydrogen bonds.
Electrochemical study on (NN)Fe3 (CO)9 ((NN) = 2,3-diazanorbornene) and related compounds. A new example of activation of carbon monoxide replaceme…
1985
Abstract The compound (NN)Fe 3 (CO) 9 ( 1 ) in tetrahydrofuran undergoes two reversible one-electron reduction processes in cyclic voltammetry at the platinum electrode. A rapid electron transfer-catalyzed reaction occurs when 1 is reduced in the presence of L (L = P(OMe) 3 ) and this gives (NN)Fe 3 (CO) 8 L ( 2 ), quantitatively. Only an electron-induced nucleophilic substitution is observed for compound 2 under the same conditions, yielding (NN)Fe 3 (CO) 7 L 2 , which undergoes a similar reaction but with much lower efficiency, to give (NN)Fe 3 (CO) 6 L 3 .
