Ru(II)-Arene Complexes of Curcumin and Bisdesmethoxycurcumin Metabolites
Paul Joseph Dyson, Farzaneh Fadaei Tirani, Mouna Hadiji
Curcuminoids and their complexes continue to attract attention in medicinal chemistry, but little attention has been given to their metabolic derivatives. Here, the first examples of (arene)Ru(II) complexes with curcuminoid metabolites, tetrahydrocurcumin ...
Amer Chemical Soc2024Quantification of Native Lignin Structural Features with Gel-Phase 2D-HSQC0 Reveals Lignin Structural Changes During Extraction
Jeremy Luterbacher, Stefania Bertella
Our ability to study and valorize the lignin fraction of biomass is hampered by the fundamental and still unmet challenge of precisely quantifying native lignin's structural features. Here, we developed a rapid elevated-temperature H-1-C-13 Heteronuclear S ...
Wiley-V C H Verlag Gmbh2024Three-membered cyclic digermylenes stabilised by an N-heterocyclic carbene dagger
Treatment of potassium salts of silole dianions with donor stabilised germanium dichlorides gave the anticipated silagermafulvenylidenes R2Si = Ge(Do) (R2Si = 1-silacyclopentadiendiyl, Do = N-heterocyclic carbene (NHC)) only as transient intermediates in a ...
ROYAL SOC CHEMISTRY2021Diiron Complexes with a Bridging Functionalized Allylidene Ligand: Synthesis, Structural Aspects, and Cytotoxicity
Paul Joseph Dyson, Lucinda Kate Batchelor, Silvia Schoch
Regio- and stereoselective nucleophilic attack of cyanide (from NBu4CN) to cationic diiron vinyliminium compounds [Fe2Cp2(CO)(mu-CO){mu-eta(1):eta(3)-C-(R')C(R '')-CNMe2}]CF3SO3 ([1a-f]CF3SO3) affords the nitrile-aminoallylidene derivatives 2a-f in good to ...
AMER CHEMICAL SOC2020A Factor Two Improvement in High-Field Dynamic Nuclear Polarization from Gd(III) Complexes by Design
David Lyndon Emsley, Marinella Mazzanti, Anne-Sophie Chauvin, Dominik Józef Kubicki, Gabriele Stevanato, Georges Guévork Jean-Jacques Menzildjian
Gadolinium(III) complexes have recently been demonstrated to have potential as polarizing agents for high-field dynamic nuclear polarization (DNP) NMR spectroscopy. By tailoring the ligand design to reduce the zero-field splitting (ZFS), we demonstrate a q ...
2019Novel osmium(II)-cymene complexes containing curcumin and bisdemethoxycurcumin ligands
Paul Joseph Dyson, Lucinda Kate Batchelor
The first examples of (arene)Os(II) curcuminoid derivatives have been prepared and characterized. The neutral complexes [(p-cym)Os(curc)Cl] (1) and [( p-cym)Os(bdcurc)Cl] ( 2), together with the cationic derivatives [( p-cym)Os(curc)(PTA)][SO3CF3] (3) and ...
ROYAL SOC CHEMISTRY2019Chlorambucil conjugates of dinuclear p-cymene ruthenium trithiolato complexes: synthesis, characterization and cytotoxicity study in vitro and in vivo
Paul Joseph Dyson, Patrycja Nowak-Sliwinska
Four diruthenium trithiolato chlorambucil conjugates have been prepared via Steglich esterification from chlorambucil and the corresponding trithiolato precursors. All conjugates are highly cytotoxic towards human ovarian A2780 and A2780cisR cancer cell li ...
Springer Verlag2016Tetracarboxylatoplatinum(IV) complexes featuring monodentate leaving groups - A rational approach toward exploiting the platinum(IV) prodrug strategy
A series of novel symmetrically and unsymmetrically coordinated platinum(IV) complexes with monodentate carboxylato ligands was synthesized. The compounds exhibit a general coordination sphere of [Pt(en)(OCOR)(2)(OCOR')(OCOR '')1, where the carboxylato lig ...
Elsevier Science Inc2015Method for nuclear magnetic resonance (NMR) spectroscopy measurements using long-lived coherences (LLC)
Geoffrey Bodenhausen, Paul Romeo Vasos, Riddhiman Sarkar, Puneet Ahuja
A method for nuclear magnetic resonance (NMR) spectroscopy of a sample comprises preparation of the sample and carrying out an NMR spectroscopy measurement. Preparation includes excitation of long lived coherences (LLC) between the singlet state S0 and the ...
2013Aqueous Oxidation of Sulfonamide Antibiotics: Aromatic Nucleophilic Substitution of an Aniline Radical Cation
Jeremy Samuel Arey, Peter Rudolf Tentscher
Sulfonamide antibiotics are an important class of organic micropollutants in the aquatic environment. For several, sulfur dioxide extrusion products have been previously reported upon photochemical or dark oxidation. Using quantum chemical modeling calcula ...
