Chem. Comm. [BCB] / [POMAM]

Abstract: Copper(II) forms well-known and stable complexes with peptides having histidine at position 2 (Xxx-His) or 3 (Xxx-Zzz-His). Their properties differ considerably due to the histidine positioning. Here we report that in the hybrid motif Xxx-His-His, the Cu(II)-complexes can be switched between the Xxx-His and the Xxx-Zzz-His coordination modes by addition of external...[more]

Inorg. Chem. [BCB] / [POMAM]

Abstract : It was shown that His3 of human copper transporter 1 (hCtr1) prompts the ATCUN-like Cu(II) coordination for model peptides of the hCtr1 N-terminus. Its high Cu(II) affinity is a potential driving force for the transfer of Cu(II) from extracellular Cu(II) carriers to hCtr1. Having a sequence similar to that of hCtr1, hCtr2 has been proposed as another human copper transporter. However,...[more]

techniques de l'ingénieur [POMAM]

Résumé : Les propriétés magnétiques des matériaux sont exploitées dans de nombreuses applications : des plus classiques, composants électromécaniques, enregistrement magnétique, aux plus élaborées et futuristes, comme la réfrigération magnétique ou l'électronique de spin. Cet article introduit a notion de Liquide Ionique (LI) avec son extension aux composés incorporant des ions magnétiques...[more]

Inorg. Chem. [POMAM]

Abstract : Two trinuclear CuII pyrazolato complexes with a Cu3(μ3-E)-core (E = O2– or OH–) and terminal nitrite ligands in two coordination modes were characterized crystallographically, spectroscopically, and electrochemically. One-electron oxidation of the μ3-O species produces a delocalized, mixed-valent, formally CuII2CuIII-nitrite, but no nitrate. In contrast, under reducing...[more]

Organic & Biomolecular Chemistry [SOPhy]

Abstract : An operationally simple synthesis of activated ynesulfonamides and enesulfonamides is described.  Ynesulfonamides can be obtained through reaction of sulfonylamides with activated bromoalkynes and Triton B in a short time at room temperature. Likewise, terminal alkynes react with sulfonylamides to provide enesulfonamides. Z/E enesulfonamides can be transformed exclusively into E...[more]
