CDC7 inhibition impairs neuroendocrine transformation in lung and prostate tumors through MYC degradation

Neuroendocrine (NE) transformation is a mechanism of resistance to targeted therapy in lung and prostate adenocarcinomas leading to poor prognosis. Up to date, even if patients at high risk of transformation can be identified by the occurrence of Tumor Pro ...

Anticancer activity of RAPTA-EA1 in triple-negative BRCA1 proficient breast cancer cells: single and combined treatment with the PARP inhibitor olaparib

Paul Joseph Dyson

RAPTA-EA1 is a promising glutathione transferase (GSTP-1) inhibitor that has previously been shown to inhibit the growth of various breast cancer cells. We studied the anticancer activity of RAPTA-EA1 on triple-negative BRCA1 competent breast cancer MDA-MB ...

Computational characterisation of the selectivity and binding mode of mono- and binuclear transition metal based anticancer compounds

Thibaud Edouard Alistair von Erlach

The rising resistance and the severe side effects associated with classical anticancer drugs such as cisplatin or mercaptopurines has triggered the development of novel antitumourous agents based on transition metal (e.g. ruthenium, osmium, and gold) organ ...

Screening-based approach to discover effective platinum-based chemotherapies for cancers with poor prognosis

Paul Joseph Dyson, Gerardo Turcatti, Fabien Kuttler, Damiano Banfi, Hristo Plamenov Varbanov

Drug combinations are extensively used to treat cancer and are often selected according to complementary mechanisms. Here, we describe a cell-based high-throughput screening assay for identification of synergistic combinations between broadly applied plati ...

Development of mass spectrometric methods to understand the mechanism of action of transition metal-based anticancer compounds

Fook Seng Ronald Lee

Metal based anti-cancer drugs (metallodrugs) such as cisplatin are a cornerstone of cancer chemotherapy. However, development of this class of compound has been hindered by our lack of understanding of how they function. This is mainly because existing met ...

In vivo anti-tumor activity of the organometallic ruthenium(II)-arene complex [Ru(eta(6)-p-cymene)-Cl-2(pta)] (RAPTA-C) in human ovarian and colorectal carcinomas

Paul Joseph Dyson, Patrycja Nowak-Sliwinska, Andrea Brett Gasser

Based on the clinical success of platinum-based anti-cancer drugs such as cisplatin, carboplatin and oxaliplatin, a variety of other metal-based anti-cancer compounds are being investigated. In particular, a number of ruthenium-based compounds have been id ...

DNA Reactivity Profile of trans-Platinum Planar Amine Derivatives

Alexey Nazarov

New trans-platinum planar amines (TPAs) represent a family of platinum-based drugs with cytotoxicity equivalent to that of cisplatin, but with negligible cross-resistance. According to the substitution pattern around the metal center, distinct DNA adducts ...

X-ray absorption spectroscopy studies of the adducts formed between cytotoxic gold compounds and two major serum proteins

Angela Casini

Gold metallodrugs form a class of promising antiproliferative agents showing a high propensity to react with proteins. We exploit here X-ray absorption spectroscopy (XAS) methods [both X-ray absorption near-edge spectroscopy (XANES) and extended X-ray abso ...

Molecular Mechanisms and Proposed Targets for Selected Anticancer Gold Compounds

Angela Casini

Nowadays, gold compounds constitute a family of very promising experimental agents for cancer treatment. Indeed, several gold(I) and gold(III) compounds were shown to manifest outstanding antiproliferative properties in vitro against selected human tumor c ...

Influence of the Arene Ligand, the Number and Type of Metal Centers, and the Leaving Group on the in Vitro Antitumor Activity of Polynuclear Organometallic Compounds

Kay Severin, Alexey Nazarov, Christian Hartinger

Dinuclear ruthenium complexes were shown to exhibit strong antiproliferative properties in human tumor cell lines. In order to extend the structure−activity relationships (SARs), a series of new RuII(arene)X complexes (X = Cl, Br, I) linked by pyridinone-b ...

Carbohydrate-metal complexes and their potential as anticancer agents

Paul Joseph Dyson, Christian Hartinger, Alexey Nazarov

A review. Platinum complex-based chemotherapy is one of the major treatment options of many malignancies. Although severe side effects occur, and only a limited spectrum of tumors can be cured, Pt compds. are used in every second therapy scheme. Thus, many ...
