Leishmanicidal and Cholinesterase Inhibiting Activities of Phenolic Compounds from Allanblackia monticola and Symphonia globulifera

open access: yesMolecules, 2007
In a preliminary antiprotozoal screening of several Clusiaceae species, the methanolic extracts of Allanblackia monticola and Symphonia globulifera showed high in vitro leishmanicidal activity.

Using the Man9(GlcNAc)2 – DC-SIGN pairing to probe specificity in photochemical immobilization [PDF]

open access: yes, 2010
We demonstrate the expected preference of an immobilised oligosaccharide Man(9)(GlcNAc)(2) upon a 96-well photochemical array, for its known receptor, the cell-surface lectin Dendritic Cell-Specific ICAM3 Grabbing Nonintegrin (DC-SIGN) when compared to ...

Gold(I) Phosphine/Phosphido‐Borohydride Complexes

open access: yesEuropean Journal of Inorganic Chemistry, EarlyView.
Synthesis, structure, and electrochemical characteristics of a homologous series of gold(I) complexes featuring phosphine and phosphido–borohydride ligands. A homologous series of linear, mononuclear gold(I) phosphine/phosphido‐borohydride complexes, encompassing [Au(PR3)2]+ 1, [Au(PR3)(PR2BH3)] 2 and [Au(PR2BH3)2]– 3 (R = tBu, Ad), has been prepared ...

Metabolic profile and root development of Hypericum perforatum L. in vitro roots under stress conditions due to chitosan treatment and culture time [PDF]

open access: yes, 2016
The responses of Hypericum perforatum root cultures to chitosan elicitation had been investigated through 1H-NMR-based metabolomics associated with morpho-anatomical analyses.

Phenolate‐ and Alcoholate‐Based Chromium N‐Heterocyclic Carbene Complexes: Structural Peculiarities, Magnetometric and Electron Paramagnetic Resonance Study, and Catalytic Ethylene Oligomerization

open access: yesEuropean Journal of Inorganic Chemistry, EarlyView.
The first low‐oxidation (I/III) state chromium‐complex bearing a O‐chelating NHC ligand has been synthesized and structurally characterized by single‐crystal X‐ray analysis. The formation of the mixed‐valence species was further supported by SQUID magnetometry and high‐field electron paramagnetic resonance (EPR) spectroscopy.

Gold Nanoparticles Supported on Poly(Phenylene Oxide) as Selective and Versatile Catalyst for Hydroamination of Arylacetylenes with Anilines

open access: yesEuropean Journal of Inorganic Chemistry, EarlyView.
Gold nanoparticles supported on poly(2,6‐dimethyl‐1,4‐phenylene oxide) (AuNPs‐PPO) demonstrates efficient and selective hydroamination, with performance tuned by reaction conditions and substrate design. Electron‐withdrawing substituents enhance conversion while preserving E‐imine selectivity, highlighting a key role of intermediate acidity.

Mechanochemical Hydrodeoxygenations

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
A silver‐catalyzed mechanochemical hydrodeoxygenation with triethylsilane as reductant allows to convert ketones to the corresponding methylene derivatives in good yields after a short reaction time. Selected examples show that also alcohols, ethers, and sulfoxides can react. In this work, a mechanochemical hydrodeoxygenation (HDO) was developed. Using
