Direct evidence for a coordination-insertion mechanism of ethylene oligomerization catalysed by neutral 2,6-bisiminopyridine iron monoalkyl complexes
(Royal Society of Chemistry, 2014)
1H NMR studies on ethylene oligomerization catalysed by the neutral monoalkyl complex [Fe(Me)(iPrBIP)] allow direct observation of alkyl iron intermediates as well as reversible ethylene coordination to the metal center, ...

Characterization of the kisspeptin system in human sperm
(European Academy of Andrology, 2012)
Kisspeptin, the product of the KISS1 gene, plays an essential role in the regulation of spermatogenesis acting primarily at the hypothalamic level of the gonadotropic axis. However, the presence of kisspeptin and its ...

β-Hydrogen Elimination Reactions of Nickel and Palladium Methoxides Stabilised by PCP Pincer Ligands
(John Wiley & Sons, 2015)
Nickel and palladium methoxides [((iPr)PCP)M-OMe], which contain the (iPr)PCP pincer ligand, decompose upon heating to give products of different kinds. The palladium derivative cleanly gives the dimeric Pd(0) complex ...

Preparation of Chitosan-supported Urea Materials and their Application in Some Organocatalytic Procedures
(Elsevier, 2018)
An efficient and mild procedure was developed for the preparation of three chitosan-supported ureas containing electron-withdrawing groups. These catalysts were characterized and employed as organocatalysts in different ...

Pharmacological chaperone therapy for Gaucher disease: A patent review
(Taylor & Francis, 2011)
Introduction: Mutations in the gene encoding for acid β-glucosidase (β-glucocerebrosidase, GlcCerase) are seen in Gaucher disease (GD), which give rise to significant protein misfolding effects and result in progressive ...

Hydrogenation of imines catalysed by ruthenium(ii) complexes based on lutidine-derived CNC pincer ligands
(Royal Society of Chemistry (Great Britain), 2013)
The preparation of new Ru(ii) complexes incorporating fac-coordinated lutidine-derived CNC ligands is reported. These derivatives are selectively deprotonated by tBuOK at one of the methylene arms of the pincer, leading ...

Mannosyl-coated nanocomplexes from amphiphilic cyclodextrins and pDNA for site-specific gene delivery
(Elsevier, 2011-10)
Fully homogeneous facial amphiphiles consisting in a cyclodextrin (CD) platform onto which a polycationic cluster and a multi-tail hydrophobic moiety have been installed (polycationic amphiphilic CDs; paCDs) self-organized ...

Oxidative stress is tightly regulated by cytochrome c phosphorylation and respirasome factors in mitochondria
(National Academy of Sciences, 2018)
Respiratory cytochrome c has been found to be phosphorylated at tyrosine 97 in the postischemic brain upon neuroprotective insulin treatment, but how such posttranslational modification affects mitochondrial metabolism is ...

Mechanocatalytic Depolymerization of Cellulose With Perfluorinated Sulfonic Acid Ionomers
(Frontiers Media, 2018)
Here, we investigated that the mechanocatalytic depolymerization of cellulose in the presence of Aquivion, a sulfonated perfluorinated ionomer. Under optimized conditions, yields of water soluble sugars of 90-97% were ...

Cationic Platinum(II) σ-SiH Complexes in Carbon Dioxide Hydrosilation
(John Wiley & Sons, 2016)
The low-electron-count cationic platinum complex [Pt(ItBu’)(ItBu)][BAr], 1, interacts with primary and secondary silanes to form the corresponding σ-SiH complexes. According to DFT calculations, the most stable coordination ...
