Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.
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.
The kinetics and mechanism of substitution reactions of novel monofunctional Pt(tpdm)Cl and Pd(tpdm)Cl complexes (where tpdm = tripyridinedimethane) and their aqua analogues with thiourea (tu), L-methionine (L-met), glutathione (GSH), and guanosi ...
An updated picture of the ligand sets and copper-ligand atom bond lengths in proteins is presented which takes advantage of (i) the approximately twofold increase in the number of entries for copper-containing proteins in the PDB since the last study of th ...
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 ...
The knowledge and understanding of the mechanism as well as the rate constant of the solvent exchange reactions are fundamental, since these reactions represent an important step in complex formation reactions on metal ions. Solvent exchange reactions in a ...
The synthesis, structure, and reactivity of a five-coordinate model complex of [Fe]-hydrogenase are described. The work suggests that the iron center in [Fe]-hydrogenases could be five-coordinate in the resting state. ...
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 ...
A mononuclear iron bis(carbonyl) pyridonate complex (1), which exhibits several common structural features with the active site of the iron−sulfur cluster-free [Fe]- hydrogenase, was synthesized and characterized. Spectroscopic data of 1 suggests a 2+ oxid ...
Cisplatin is one of the most important and widely used anticancer drug in clinical use. However, its effectiveness is limited by its high toxicity and incidence of drug resistance. This has provided motivation for the search for transition metal-based drug ...
A new target in AIDS therapy development is HIV-1 integrase (IN). It was proven that HIV-1 IN required divalent metal cations to achieve phosphodiester bond cleavage of DNA. Accordingly, all newly investigated potent IN inhibitors contain chemical fragment ...
[Fe]-hydrogenase, one of three types of hydrogenases, activates molecular hydrogen. Here, using DFT computations, we examine the electronic elements governing the binding of small ligands to a recently synthesized [Fe]-hydrogenase biomimic. Computed reacti ...
