Heterometallic platinum(ii) compounds with beta-aminoethylferrocenes: Synthesis, electrochemical behaviour and anticancer activity

A new family of heterometallic compounds 3-6 containing ferrocenyl and platinum(ii) centers has been synthesized by reaction of 1-beta- aminoethylferrocene (1) and 1,1?-bis(beta-aminoethyl)ferrocene (2) with Pt(ii) precursors. Using K2[PtCl4] as the Pt(ii) source, the cis-square-planar neutral compounds [Fe{eta5-C 5H4(CH2)2NH2} 2PtCl2] (3) and [{Fe(eta5-C5H 4(CH2)2NH2)(eta5-C 5H5)}2PtCl2] (5) were obtained. Reaction of cis-[PtCl2(dmso)2] with 1 and 2 resulted in the displacement of dmso and chloride ligands from the platinum coordination sphere, affording the cationic and neutral compounds [Fe{eta5- C5H4(CH2)2NH2} 2Pt(dmso)Cl]Cl (4) and [Fe(eta5-C5H 4(CH2)2NH2)(eta5-C 5H5)Pt(dmso)Cl2] (6). Compounds 3-6 were thoroughly characterized using multinuclear (1H, 13C, 195Pt) NMR, IR spectroscopy, ESI mass spectrometry and elemental analysis. Single-crystal X-ray analysis of heterometallic 6 confirmed the cis geometry of the molecule and revealed that the platinum atom is held in a perfect square-planar geometry. The electrochemical behaviour of the heterometallic compounds 3-6, which has been examined by cyclic (CV) and square wave (SWV) voltammetries in dichloromethane and dmso solution, is characterized by the reversible one-electron oxidation of the ferrocene moieties. The results of the biological activity studies revealed that the organometallic complex 5 is active against all cell lines with GI50 values in the range 1.7-2.3 muM. When compared to the standard anticancer drug cisplatin, heterotrimetallic 5, possessing two aminoethylferrocenyl units coordinated to the Pt(ii) center, showed a greater activity profile in the colon cancer cell line. Cell cycle studies revealed that the new mixed compound exhibits a mechanism of action different to cisplatin.

Zinc, cadmium and mercury complexes of redox-active cyanomanganese carbonyl ligands: Intramolecular electron transfer through tetrahedral d10 metal centres

The redox-active cyanomanganese carbonyl ligands cis- and trans-[Mn(CN)(CO)2{P(OR)3}(dppm)] (R = Ph or Et dppm = Ph2PCH2PPh2) reacted with ZnBr2, CdI2 and Hg(NO3)2 to give the tetrahedral (at M) complexes [X2M{(mu-NC)MnLx}2] [MX2 = ZnBr2, CdI2 or Hg(NO3)2; Lx = cis- or trans-(CO)2{P(OR)3}(dppm); R = Ph or Et]; similarly [Mn(CN)(NO)PPh3)(eta-C5H4Me)] gives [X2M{(mu-NC)MnLx}2] {MX2 = ZnBr2 or CdI2 Lx = (NO)-(PPh3)(eta-C5H4Me)}. Treatment of [Br2Zn{(mu-NC)MnLx}2] [Lx = trans-(CO)2{P(OEt)3}(dppm)] 4 with TlPF6 in the presence of 1 or 2 equivalents of trans-[Mn(CN)(CO)2{P(OEt)3}(dppm)] gave the tetra- and penta-metallic complexes [BrZn{(mu-NC)MnLx}3][PF6] 13 and [Zn{(mu-NC)MnLx}4][PF6]2 14 [Lx = trans-(CO)2{P(OEt)3}(dppm)] respectively. Differential pulse volammetry showed that 4, 13 and 14 are oxidised to weakly interacting mixed-valence complexes. The reaction of trans-[Mn(CN)(CO)(dppm)2] with ZnBr2 or CdX2 (X = Br or I) in thf gave the bimetallic species [X2(thf)M(mu-NC)Mn(CO)(dppm)2] (MX2 = ZnBr2 or CdI2) and [Br2Cd(mu-NC)Mn(CO)(dppm)2] which are oxidised by [Fe(eta-C5H5)2][PF6] to the MnII complexes [X2(thf)M(mu-NC)Mn(CO)(dppm)2][PF6] and [Br2Cd(mu-NC)Mn(CO)(dppm)2][PF6].

The synthesis of a C2 symmetric 1,1? ,2,2?-tetrasubstituted ferrocene system was discussed. The route involved the reduction of ferrocenyl carbonyl compounds which gave access to a range of alcohols, alkenes, alkanes, ethers, and 2-oxa[3]ferrocenophanes depending on the precise conditions used. The loss of optical activity of 1,1?-bis(hydroxymethyl)ferrocenes and 1,1?-bis(hydroxymethyl)ruthenocenes, which had been prepared by asymmetric reduction, was demonstrated in an acidic medium by extensive 1H NMR studies.

Reuseable monolithic nanoporous graphite-supported nanocatalysts (Fe, Au, Pt, Pd, Ni, and Rh) from pyrolysis and galvanic transmetalation of ferrocene-based polyamide aerogels

Polyamide aerogels with ferrocene as a monomer repeat unit were prepared in one step from ferrocene dicarboxylic acid and tris(4-isocyanatophenyl)methane. Pyrolysis at ?800 C yielded nanoporous carbons doped throughout with crystallites of alpha-Fe (about 50 nm in diameter), which in turn were shrouded in graphitic ribbons (<30 graphene layers thick). Transmetalation was carried out with aqueous solutions of Au, Pt, Pd, Rh, and Ni salts, via a path akin to galvanic corrosion, whereas graphitic ribbons separated anodes (alpha-Fe particles) from cathodes (defects along the ribbons). The new metallic phases formed clusters of smaller crystallites (10-20 nm in diameter) on the graphitic ribbons, leaving behind empty cage-like formations previously occupied by the Fe(0) nanoparticles. All metal-doped carbons were monolithic and over 85% porous. Catalytic activity was demonstrated with the oxidation of benzyl alcohol to benzaldehyde catalyzed with carbon-supported Au or Pt, the reduction of nitrobenzene by hydrazine to aniline catalyzed with carbon-supported Fe, and two Heck coupling reactions of iodobenzene with styrene or butyl acrylate, catalyzed with carbon-supported Pd. The distinguishing feature of those catalysts was that they could be just picked up, for example, with a pair of tweezers, and redeployed in a new reaction mixture immediately, thus bypassing less efficient recovery processes like filtration.

Synthesis and antioxidant activities of ferrocenyl-containing curcumin analogues

Background: Metal organic compounds have attracted considerable attention since the advent of Salvarsan, a metal organic compound for the treatment of syphilis. Ferrocene as an effective phenyl bioisostere is becoming a viable platform for drug design by virtue of its redox properties, high lipophilicity and three-dimensional metallocene unit, which may lead to some changes in selectivity toward biological targets compared with phenyl or alkyl groups. Therefore, ferrocene seems to an appropriate candidate for improving the antioxidant activity of drugs. Methods: We synthesized four ferrocenyl-containing curcumin analogues by introducing ferrocenyl groups into the active methylene groups to obtain higher antioxidant activity than the parent ferrocene-substituted curcumin analogues, and their antioxidant activities were evaluated in 2, 2?-azobis (2-amidinopropane hydrochloride) (AAPH) and Cu2+/glutathione(GSH)-induced oxidation of DNA, and in trapping 2, 2?-diphenyl-1-picrylhydrazyl (DPPH), 2, 2?-azinobis(3-ethylbenzothiazoline-6-sulfonate) cationic radicals (ABTS+?) and galvinoxyl radicals. Results: These ferrocenyl-containing curcumin analogues can protect DNA against Cu2+/GSH-induced oxidation, and scavenge 5.7, 6.9, 5.5 and 5.3 radicals in protecting DNA against AAPH-induced oxidation. Compounds (3)~(5) can trap more DPPH, ABTS+? and galvinoxyl radicals than compound (6). The substituents and iron atoms play an antioxidant role in ferrocenyl-containing curcumin analogues. Conclusion: The introduction of ferrocenyl group results in a higher antioxidant activity than the traditional hydroxyl-involved curcumin analogues. The ferrocenyl group is a powerful antioxidative group that could be used to modify natural antioxidants. The electron-accepting group attaching to the phenyl-group could further increase the antioxidant activity. Ferrocene-containing curcumin analogues show higher activities in quenching radicals and protecting DNA against radical-induced oxidation. Therefore, the introduction of ferrocenyl group into the natural antioxidant may contribute to increase the antioxidant activity.
