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 ...

Surface-Active Properties of Lipophilic AntioxidantsTyrosol and Hydroxytyrosol Fatty Acid Esters: A PotentialExplanation for the Nonlinear Hypothesis of the AntioxidantActivity in Oil-in-Water Emulsions
(American Chemical Society, 2001)
Our group has recently observed a nonlinear tendency in antioxidant capacity of different hydroxytyrosol fatty acid esters in fish oil-in-water emulsions, where a maximum of antioxidant efficiency appeared for hydroxytyrosol ...

Improved non-covalent biofunctionalization of multi-walled carbon nanotubes using carbohydrate amphiphiles with a butterfly-like polyaromatic tail
(Springer, 2010)
We have developed an efficient strategy for the non-covalent functionalization of multi-walled carbon nanotubes (MWCNTs) which allows a biomimetic presentation of carbohydrates on their surface by π-π stacking interactions. ...

Glycoligand-targeted core-shell nanospheres with tunable drug release profiles from calixarene-cyclodextrin heterodimers
(Royal Society of Chemistry, 2014)
Stable core–shell nanospheres self-assemble in water from heterodimers combining a hydrophobic calix[4]arene moiety and a hydrophilic β-cyclodextrin head; their potential to encapsulate and provide sustained release of the ...

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 ...

Coupling of Aromatic Aldehydes with CO2Me-Substituted TpMe2Ir(III) Metallacyclopentadienes
(American Chemical Society, 2012)
The fully CO2Me substituted aquo-iridacyclopentadiene 1 reacts with a variety of aromatic aldehydes, at 90–120 °C, with the formation of bicyclic Fischer-type carbenes, generated by the transfer of the aldehydic H atom to ...

Synthesis, structure and reactivity of Pd and Ir complexes based on new lutidine-derived NHC/phosphine mixed pincer ligands
(Royal Society of Chemistry, 2016)
Coordination studies of new lutidine-derived hybrid NHC/phosphine ligands (CNP) to Pd and Ir have been performed. Treatment of the square-planar [Pd(CNP)Cl](AgCl2) complex 2a with KHMDS produces the selective deprotonation ...

Structural diversity and magnetic properties of copper(ii) quinaldinate compounds with amino alcohols
(Royal Society of Chemistry, 2022)
The reactions between [Cu(quin)2(H2O)] (quin− = the anionic form of quinoline-2-carboxylic acid) and a series of aliphatic amino alcohols have yielded structurally very diverse copper(II) complexes, labelled a–g. Single-crystal ...

Deciphering of polycationic carbohydrate based non-viral gene delivery agents by ESI-LTQ-Orbitrap using CID/HCD pairwise tandem mass spectrometry
(Royal Society of Chemistry, 2016)
For almost three decades, gene therapy has been gaining interest to efficiently treat some severe diseases. In such context, the discovery of an efficient non-viral gene carrier to deliver genetic material into targeted ...

Improvement on binding of chondroitin sulfate derivatives to midkine by increasing hydrophobicity
(Royal Society of Chemistry, 2016)
The interactions between chondroitin sulfate (CS) and a wide number of proteins modulate important biological processes. Here, the binding properties to midkine and pleiotrophin of sulfated, fully protected intermediates, ...
