Biophysical J. [Biophysique des membranes et RMN]

Abstract : Apolipoprotein A-I is the major protein component of high-density lipoproteins and fulfils important functions in lipid metabolism. Its structure consists of a chain of tandem domains of amphipathic helices. Using this protein as a template membrane scaffolding protein, class A amphipathic helical peptides were designed to support the amphipathic helix theory and later as therapeutic...[En savoir plus]

Chemical Reviews [LCQ]

Abstract : Intersystem crossing (ISC), formally forbidden within nonrelativistic quantum theory, is the mechanism by which a molecule changes its spin state. It plays an important role in the excited state decay dynamics of many molecular systems and not just those containing heavy elements. In the simplest case, ISC is driven by direct spin–orbit coupling between two states of different...[En savoir plus]

Cover Chem. Eur. J. [LCC]

Cover abstract : Selective transmetallation from copper(I) or silver (I) to palladium(0) at P donors of the rigid multidentate ligand PCNHCP results when [M3(μ3‐PCNHCP)2](OTf)3 (M=Cu, Ag) reacts with [Pd(PPh3)4]. The graphic illustrates the double short‐bite nature of the ligand system that stabilizes the metal chain and favors attractive d10‐d10 closed‐shell interactions without restraining...[En savoir plus]

JOC [LASYROC]

Abstract: The copper(I)-doped zeolite CuI−USY proved to be a versatile, efficient, and recyclable catalyst for various Ullmann-type coupling reactions. Easy to prepare and cheap, this catalytic material enables the arylation and heteroarylation of diverse O-, N-, S-, and C-nucleophiles under ligand-free conditions while exhibiting large functional group compatibility. The facility of this...[En savoir plus]

PCCP [POMAM]

Summary : Magnetic dipole interactions are extensively used in NMR and EPR spectroscopies to probe interatomic distances between paramagnetic centers when crystal structures are not readily available. However, this usually concerns spin carriers whose spin density is fully localised, such magnetic nuclei, transition-metal ions and organic radicals. In this work we show that it is possible to...[En savoir plus]

Cover Dalton Transactions [LCC, POMAM]

Abstract: The double aminolysis reaction of [Co{N(SiMe3)2}2] by the salt 1-(6-((dicyclohexylphosphaneyl)methyl)pyridin-2-yl)-3-(2,6-diisopropylphenyl)-1H-imidazol-3-ium bromide, which contains one phosphane, one pyridine and one imidazolium groups, of formula [o-Cy2PCH2(C5H3N)(o-C3H3N2DiPP)]Br and abbreviated as (CyPNpyrCim)Br, was previously shown to afford the Co(II) complex [Co(CyP*NaCNHC)Br]...[En savoir plus]

Biomolecules [Biophysique des membranes et RMN]

Abstract: Biophysical and structural investigations are presented with a focus on the membrane lipid interactions of cationic linear antibiotic peptides such as magainin, PGLa, LL37, and melittin. Observations made with these peptides are distinct as seen from data obtained with the hydrophobic peptide alamethicin. The cationic amphipathic peptides predominantly adopt membrane alignments...[En savoir plus]
