Structural Basis of the Inhibition of GH1 β-glucosidases by Multivalent Pyrrolidine Iminosugars
(Elsevier, 2019)
The synthesis of multivalent pyrrolidine iminosugars via CuAAC click reaction between different pyrrolidine-azide derivatives and tri- or hexavalent alkynyl scaffolds is reported. The new multimeric compounds, together ...

Ir-Catalyzed Atroposelective Desymmetrization of Heterobiaryls: Hydroarylation of Vinyl Ethers and Bicycloalkenes
(American Chemical Society, 2020)
A highly regio-, diastereo-, and enantioselective, scalable Ir-catalyzed hydroarylation of electron-rich acyclic and tensioned cyclic olefins with heterobiaryls is described. The reaction of acyclic vinyl ethers, dihydrofuran, ...

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 ...

Tacrine-sugar mimetic conjugates as enhanced cholinesterase inhibitors
(Royal Society of Chemistry, 2021-03-14)
We have used the Cu(i)-catalyzed azide-alkyne Huisgen cycloaddition reaction to obtain two families of bivalent heterodimers where tacrine is connected to an azasugar or iminosugar, respectively,vialinkers of variable ...

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 ...

Development of tacrine clusters as positively cooperative systems for the inhibition of acetylcholinesterase
(Taylor & Francis Open Access, 2021)
The synthesis of four tetra-tacrine clusters where the tacrine binding units are attached to a central scaffold via linkers of variable lengths is described. The multivalent inhibition potencies for the tacrine clusters ...
