Dibenzyl and diallyl 2,6-bisiminopyridinezinc (II) complexes: selective alkyl migration to the pyridine ring leads to remarkably stable dihydropyridinates

Jun 27, 2013 | Artículos del Mes

Transition metal complexes stabilized by Bis(Imine)Pyridine (BIP) ligands are very attractive species due to their high activity and selectivity towards diverse catalytic reactions such as organic hydrosilylation and hydrogenation, or olygomerisation and...

Glyconanosomes: Disk-Shaped Nanomaterials for the Water Solubilization and Delivery of Hydrophobic Molecules

May 27, 2013 | Artículos del Mes, Artículos del Mes, Artículos del Mes, Artículos del Mes, Artículos del Mes

Herein, we describe the first report on a new class of disk-shaped and quite monodisperse water-soluble nanomaterials that we named glyconanosomes (GNS). GNSs were obtained by sliding out the cylindrical structures formed upon self-organization and photopolymerization...

Interconversion of Quadruply and Quintuply Bonded Molybdenum Complexes by Reductive Elimination and Oxidative Addition of Dihydrogen

Abr 27, 2013 | 2013, 2013, 2013, 2013, 2013, 2013

A series of dimolybdenum dihydride complexes supported by amidinate ligands and featuring a Mo—Mo quadruple bond, MoII2, has been prepared and characterized by NMR spectroscopy and x-ray crystallography. UV irradiation (365 nm) of one of these complexes, namely the...

Selective UV Reflecting Mirrors Based on Nanoparticle Multilayers

Mar 27, 2013 | Sin categoría

Un nuevo tipo de espejo nanoestructurado que refleja selectivamente la radiación ultravioleta (UV) es presentado. Multicapas periódicas porosas con propiedades de cristal fotónico son construidas a través de la deposición capa por capa de suspensiones coloidales de...

Virus-like glycodendrinanoparticles displaying quasi-equivalent nested polyvalency upon glycoprotein platforms potently block viral infection

Feb 27, 2013 | Sin categoría

Ligand polyvalency is a powerful modulator of protein–receptor interactions. In particular, host–pathogen infection interactions are often mediated by glycan ligand–protein interactions. The study of these interactions using synthetic compounds with very high copy...

Cysteine-Generated Sulfide in the Cytosol Negatively Regulates Autophagy and Modulates the Transcriptional Profile in Arabidopsis

Ene 27, 2013 | Sin categoría

In Arabidopsis thaliana, DES1 is the only identified L-Cysteine desulfhydrase located in the cytosol, and it is involved in the degradation of cysteine (Cys) and the concomitant production of H2S in this cell compartment. Detailed characterization of the T-DNA...
