Synthesis, characterisation and cytotoxicity studies of ruthenium arene complexes bearing trichlorogermyl ligands

The synthesis of five half sandwich ruthenium(II) trichlorogermyl complexes of the type [(η6-Arene)Ru(PR3)Cl(GeCl3)] (PR3 = Phosphane and phosphite ligands; Arene = p-cymene or C6H5-OC2H4OH) is reported: [(η6-p-cymene)Ru(P(OMe)3)Cl(GeCl3)] (1), [(η6-p-cyme ...

Versatile Route to trans-Platinum(II) Complexes via Manipulation of a Coordinated 3-(Pyridin-3-yl)propanoicAcid Ligand

Paul Joseph Dyson, Tina Riedel, Marta Maroto Diaz

We describe the direct coupling of alcohols and amines to a 3-(pyridin-3-yl)propanoic acid ligand coordinated to a Pt(II) to afford ester and amide derivatives. Using this approach, a family of trans-Pt(II) compounds with amine ligands bearing long perfluo ...

Vascular-targeted low dose photodynamic therapy stabilizes tumor vessels by modulating pericyte contractility

Paul Joseph Dyson, Georges Wagnières, Matthieu Philippe Emmanuel Zellweger, Tina Riedel

Vascular-targeted low-dose photodynamic therapy (L-PDT) was shown to improve chemotherapy distribution in malignant pleural tumors such as malignant pleural mesothelioma (MPM). However, the mechanisms triggered by L-PDT on the tumor vasculature are still d ...

Chemo-manipulation of tumor blood vessels by a metal-based anticancer complex enhances antitumor therapy

Paul Joseph Dyson, Hubert van den Bergh, Tina Riedel

Human pleural mesothelioma is an incurable and chemoresistant cancer. Using a nude mouse xenograft model of human pleural mesothelioma, we show that RAPTA-T, a compound undergoing preclinical evaluation, enhances tumor vascular function by decreasing blood ...

Synthesis, characterization and cytotoxicity of arene-ruthenium(II) complexes with acylpyrazolones functionalized with aromatic groups in the acyl moiety

Paul Joseph Dyson, Rosario Scopelliti, Tina Riedel

A series of neutral ruthenium(II)-arene complexes, [(arene) Ru(Q(R))Cl] (arene = p-cymene or hexamethylbenzene), containing 4-acyl-5-pyrazolonate (Q(R)) ligands with aromatic substituents in the acyl moiety (a phenyl in Q(Ph) and a 1-naphthyl in Q(naph)) a ...

Influence of Functionalized η6 -Arene Rings on Ruthenium(II) Curcuminoids Complexes

Paul Joseph Dyson, Rosario Scopelliti, Laure Debora Pittet, Tina Riedel, Agnese Petrini

A series of organometallic Ru(II) complexes containing functionalized η6‐arene ligands, together with curcumin and bisdemethoxycurcumin as O,O’‐chelating ligands and their RAPTA (ruthenium arene complexes bearing the 1,3,5‐triaza‐7‐phosphaadamantane ligand ...

Palladium(II)-Stabilized Pyridine-2-Diazotates: Synthesis, Structural Characterization, and Cytotoxicity Studies

Paul Joseph Dyson, Alexander Tskhovrebov, Tina Riedel

Well-defined diazotates are scarce. Here we report the synthesis of unprecedented homoleptic palladium(II) diazotate complexes. The palladium(II)-mediated nitrosylation of 2-aminopyridines with NaNO2 results in the formation of metal-stabilized diazotates, ...

Drug Repurposing Approach Identifies a Synergistic Drug Combination of an Antifungal Agent and an Experimental Organometallic Drug for Melanoma Treatment

Paul Joseph Dyson, Tina Riedel, Olivier Pierre Zava

By screening a drug library comprising FDA approved compounds, we discovered a potent interaction between the antifungal agent haloprogin and the experimental organometallic drug RAPTA-T, to synergistically induce cancer cell killing. The combination of th ...

Arene-Ruthenium(II) Complexes with Bioactive ortho-Hydroxydibenzoylmethane Ligands: Synthesis, Structure, and Cytotoxicity

Paul Joseph Dyson, Tina Riedel, Agnese Petrini

The synthesis of a series of neutral arene-ruthenium (II) complexes (arene = p-cymene, hexamethylbenzene, and benzene) [(arene)Ru(HDB) Cl] derived from the reaction of the appropriate arene-ruthenium(II) dimers and ortho-hydroxydibenzoylmethane (HDBH), a p ...
