J. Phys. Chem. Lett. [LCQ]

Abstract : Whereas third row transition metal carbonyl α-diimine complexes display luminescent properties and possess low-lying triplet metal-to-ligand charge transfer (MLCT) states efficiently accessible by a spin–vibronic mechanism, first row analogues hold low-lying metal-centered (MC) excited states that could quench these properties. Upon visible irradiation, different functions are...[more]

Chemistry : A European Journal [LCSOM]

Abstract : The reaction of H₃SiR (R=Ph, nBu) with a cationic Cp*‐and benzo[h]quinolinyl‐ based iridacycle [1b]+ gives rise to new [(Ir‐H)→SiRH₂]+ adducts. In the presence of tetrahydrofuran (THF) the latter adducts readily convert by H₂ gas elimination at subambient temperature into new THF‐stabilized metallacyclic Ir(III)‐“silylene” complexes that were characterized in situ by NMR spectroscopic...[more]

BBA - Biomembranes [Biophysique des membranes et RMN]

Abstract : γ-Secretase is an integral membrane protein complex and is involved in the cleavage of the amyloid precursor protein APP to produce amyloid-β peptides. Amyloid-β peptides are considered causative agents for Alzheimer's disease and drugs targeted at γ-secretase are investigated as therapeutic treatments. We synthesized new carprofen derivatives, which showed γ-secretase modulating...[more]

Biophysical J. [Biophysique des membranes et RMN]

Abstract : A synergistic enhancement of activities has been described for the amphipathic cationic antimicrobial peptides magainin 2 and PGLa when tested in antimicrobial assays or in biophysical experiments using model membranes. In the presence of magainin 2, PGLa changes from an in-planar alignment parallel to the membrane surface to a more transmembrane orientation when investigated in...[more]

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...[more]

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...[more]

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...[more]
