Spatially Resolved STD-NMR Applied to the Study of Solute Transport in Biphasic Systems: Application to Protein-Ligand Interactions
(SAGE Publications, 2019)
Fluid biphasic systems are one of the most interesting dynamic systems in chemistry and biochemistry. In nuclear magnetic resonance (NMR) spectroscopy, the study of the solute dynamics across fluid biphasic systems ...

Tacrine-O-protected phenolics heterodimers as multitarget-directed ligands against Alzheimer's disease: Selective subnanomolar BuChE inhibitors
(Elsevier, 2019-11-01)
Concerned by the devastating effects of Alzheimer's disease, and the lack of effective drugs, we have carried out the design of a series of tacrine-phenolic heterodimers in order to tackle the multifactorial nature of the ...

Synthesis of unprecedented steroidal spiro heterocycles as potential antiproliferative drugs
(Elsevier, 2018-01-01)
Herein we report the straightforward preparation of novel conformationally-restricted steroids from trans-androsterone and estrone, decorated with spiranic oxazolidin-2-one or 2-aminooxazoline motifs at C-17 as potential ...

Chirality and catalysis with aromatic N-fused heterobicyclic carbenes
(Royal Society of Chemistry, 2016)
The benzoannulation of the most common families of aromatic NHCs, imidazol-2-ylidenes and 1,2,4-triazol-3-ylidenes, results in heterobicyclic imidazo[1,5-a]pyridin-3-ylidenes (ImPy's) and [1,2,4]triazolo[4,3-a]pyridin-3-ylidenes ...

Synthesis of axially chiral heterobiaryl alkynes via dynamic kinetic asymmetric alkynylation
(Wiley, 2016)
The dynamic kinetic Pd0 -catalyzed alkynylation of racemic heterobiaryl sulfonates was used for the asymmetric synthesis of axially chiral heterobiaryl alkynes with a broad scope. The use of Pd(OAc)2/ (S)-QUINAP as the ...

Exploring architectures displaying multimeric presentations of a trihydroxypiperidine iminosugar
(Beilstein-Institut Zur Forderung der Chemischen Wissenschaften, 2015)
The synthesis of new multivalent architectures based on a trihydroxypiperidine α -fucosidase inhibitor is reported herein. Tetrava- lent and nonavalent dendrimers were obtained by means of the click chemistry approach ...

Discovery of a Potent α ‑ Galactosidase Inhibitor by in Situ Analysis of a Library of Pyrrolizidine − (Thio)urea Hybrid Molecules Generated via Click Chemistry
(American Chemical Society, 2018)
The parallel synthesis of a 26-membered-library of aromatic/aliphatic-(thio)urea-linked pyrrolizidines followed by in situ biological evaluation toward α -galactosidases has been carried out. The combination of the ...

New tacrine dimers with antioxidant linkers as dual drugs: Anti-Alzheimer's and antiproliferative agents
(Elsevier, 2017)
We have designed a series of tacrine-based homo- and heterodimers that incorporate an antioxidant tether (selenoureido, chalcogenide) as new dual compounds: for the treatment of Alzheimer's disease and as antiproliferative ...
