AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
We investigated iron oxide nanoparticles with two different surface modifications, dextran coating and cross-linked dextran coating, showing that their different internalization affects their capability to enhance radiation damage to cancer cells. The inte ...
Ruthenium-based compounds are an attractive alternative to clinically used platinum drugs due to several features including a wide range of accessible oxidation states, varied synthetic chemistry and typically lower general toxicities. One series of ruthen ...
The interaction of two ruthenium-arene-1,3,5-triaza-7-phosphaadamantane compds. ([Ru(η6-p-cymene)Cl2(pta)] and [Ru(η6-p-cymene)(C6H6O4)(pta)], termed RAPTA-C (3) and carboRAPTA-C (4), resp.) with the DNA sequence of the human breast-cancer suppressor gene ...
Tumors consist of cells whose growth and morphological characteristics are markedly different from those of normal cells. Observation of human and animal models argue that tumor development proceeds via a process formally analogous to Darwinian evolution, ...
The protein farnesyltransferase (FTase) is a Zn2+-metalloenzyme that catalyzes the farnesylation reaction, i.e., the transfer of the 15-carbon atom farnesyl group from farnesyl diphosphate (FPP) to a specific cysteine of protein substrates. Oncogenic Ras p ...
A minidevice for performing gel-free proteome prefractionation via conventional IEF in soluble carrier ampholyte buffers is reported here. It consists of a compact block of poly-oxymethylene in which eight samples and two electrode chambers are machined. E ...
Ru(II)-arene complexes with pyrone-derived ligands are rendered active against cancer cells by replacement of the coordinated O,O donor with an S,O donor. The different stabilities of these systems may explain the observed influence of the donor atoms on t ...
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+ ...
Novel derivatives of the clinically established anticancer drug oxaliplatin were synthesized. Cytotoxicity of the compounds was studied in six human cancer cell lines by means of the MTT assay. Additionally, most promising complexes were also investigated ...
New pyrrolidine-3,4-diol derivatives were prepared from D-(-)- and L(+)-phenylglycinol and tested for their ability to inhibit 25 commercial glycosidases. The influence of the substitution of the lateral side chain and of the pyrrolidine ring on the enzyme ...
