Three heteroleptic ruthenium complexes incorporating new ancillary ligands synthesized by sequential connection of different alkyl functionalities with triazole as a linker are prepared using click chemistry. These sensitizers exhibit low-energy metal-to-l ...

The invention relates to new medicaments, pharmaceutical compns. and methods of treatment of cancer. The invention discloses trimetallic clusters for use as a medicament, in particular in the treatment of cancer including metastasis. Preferably, the compds ...

A review. The promising drug candidate indazolium trans-[tetrachlorobis(1H-indazole)ruthenate(III)] (KP1019) is the second Ru-based anticancer agent to enter clin. trials. In this review, which is an update of a paper from 2006, the exptl. evidence for the ...

Application of mild hyperthermia can increase the cytotoxicity of anticancer drugs in tumour cells. In this report, we describe low molecular weight thermoactive ruthenium-based drugs with fluorous chains that are selectively triggered by mild hyperthermia ...

A series of coordination polymers contg. Group I or II metal ions, connected via an imidazolium-centered dicarboxylate ligand, have been isolated from water and characterized by single crystal X-ray diffraction. All the structures incorporate water mols. t ...

The viscosities of the ionic liqs. [bmim][PF6] and [bmim][TF2N] (bmim = 1-methyl-3-butylimidazolium, TF2N = bis(trifluoromethylsulfonyl)imide) have been detd. under CO2 pressure at 298 K. The viscosity decreases from 381 to 23 cP for [bmim][PF6] without CO ...

This review provides an introduction into the fascinating area of organometallic anticancer compounds. Although the subject dates back many years, it has witnessed considerable growth only in the past decade. A brief overview of the subject together with r ...

The effect of pressure on the Diels-Alder reaction was examined in room temperature ionic liquids, followed by high-pressure FT-IR spectroscopy using pressures up to 150 MPa. Pressure enhances the kinetic sensitivity of the reaction. The kinetic effec ...

A series of novel ruthenium(II) arene RAPTA type derivatives (arene = cymene, hexamethylbenzene) containing curcumin-based ligands (curcH = curcumin, bdcurcH = bisdemethoxycurcumin) and PTA (1,3,5-triaza-7-phosphaadamantane) have been synthesized and fully ...

A new series of eight first- and second-generation heterometallic ferrocenyl-derived metal-arene metallodendrimers, containing ruthenium(II) p-cymene, ruthenium(II)-hexamethylbenzene, rhodium(III)-cyclopentadienyl or iridium(III)-cyclopentadienyl moieties ...

Succinimide derivatives are useful building blocks for the synthesis of natural products and drugs. We describe an efficient route to succinimide derivatives comprising Pd(xantphos)Cl2-catalyzed aminocarbonylation of alkynes with aromatic or aliphatic amin ...

From their early successes in medicine, organometallic compounds continue to attract interest as potential chemotherapeutics to treat a range of diseases. Here, we show from recent literature selected largely from the last two years that organometallics of ...

Elucidating the mode of action and thereby opening the way to the design of chemotherapeutic agents is one of the major goals of metal-based anticancer research. Hydrolysis and DNA binding play an important role for pharmaceutical formulation and for exert ...

Novel ruthenium half-sandwich complexes containing (N,O)-bound pyrazolone-based beta-ketoamine ligands have been prepared, and the solid-state structures of one ligand and five complexes have been determined by single-crystal X-ray diffraction. Some of the ...

The triple-chlorido-bridged heterodimetallic dinuclear complex [(dibenzo-18-crown-6)K(m-Cl)3Ru(h6-p-cymene)] contg. an (h6-arene)RuII fragment and a Group 1 metal crown ether fragment was synthesized and characterized by spectroscopy and X-ray crystallog. ...

A series of compds. of general formula [Ru(.eta.6-p-cymene) (R2acac)(PTA)][X] (R2acac = Me2acac, tBu2acac, Ph2acac, Me2acac-Cl; PTA = 1,3,5-triaza-7-phosphaadamantane; X = BPh4, BF4), and the precursor to the Me2acac-Cl deriv. [Ru(.eta.6-p-cymene)(Me2acac- ...

Metal ions and compounds are essential to life and many people routinely take them as food supplements in the form of vitamin and mineral pills. Most non-essential metals are considered to be toxic, nevertheless, many are widely used in imaging, diagnostic ...

The cytotoxicities of the large cationic arene-ruthenium prismatic cage [Ru6(p-iPrC6H4Me)6(tpt)2(dhbq)3]6+ (tpt = 2,4,6-tris(pyridin-4-yl)-1,3,5-triazine, dhbq = 2,5-dihydroxy-1,4-benzoquinolato; 16+), and its "complex-in-a-complex" derivs. [(acac)2M-1]6+ ...
