1,4-Dideoxy-1,4-imino‑D‑arabinitol (DAB) Analogues Possessing a Hydrazide Imide Moiety as Potent and Selective α‑Mannosidase Inhibitors
Haarr, Marianne Bore; Lopez, Oscar; Pejov, Ljupcho; Fernandez-Bolanos, Jose G.; Lindback, Emil; Sydnes, Magne Olav (Peer reviewed; Journal article, 2020-07)The synthesis of two polyhydroxylated pyrrolidines as 1,4-dideoxy-1,4-imino-D-arabinitol (DAB) analogues bearing a hydrazide moiety is described. The DAB analogues act as selective and potent inhibitors of α-mannosidase ... -
Development of tacrine clusters as positively cooperative systems for the inhibition of acetylcholinesterase
Evangelista, Tereza Cristina Santos; Lopez, Oscar; Ferreira, Sabrina Baptista; Fernandez-Bolanos, Jose G.; Sydnes, Magne Olav; Lindback, Emil (Peer reviewed; Journal article, 2021-07)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 ... -
A hybrid of 1-deoxynojirimycin and benzotriazole induces preferential inhibition of butyrylcholinesterase (BuChE) over acetylcholinesterase (AChE)
Evangelista, Tereza Cristina Santos; Lopez, Oscar; Puerta, Adrian; Fernandes, Miguel X.; Ferreira, Sabrina Baptista; Padron, Jose M.; Fernandez-Bolanos, Jose G.; Sydnes, Magne Olav; Lindback, Emil (Peer reviewed; Journal article, 2022)The synthesis of four heterodimers in which the copper(I)-catalysed azide-alkyne cycloaddition was employed to connect a 1-deoxynojirimycin moiety with a benzotriazole scaffold is reported. The heterodimers were investigated ... -
Investigation of the enantioselectivity of acetylcholinesterase and butyrylcholinesterase upon inhibition by tacrine-iminosugar heterodimers
Vaaland, Ingrid Caroline; Lopez, Oscar; Puerta, Adrian; Fernandes, Miguel X.; Padron, Jose M.; Fernandez-Bolanos, Jose G.; Sydnes, Magne Olav; Lindback, Emil (Peer reviewed; Journal article, 2023-09)The copper-catalysed azide-alkyne cycloaddition was applied to prepare three enantiomeric pairs of heterodimers containing a tacrine residue and a 1,4-dideoxy-1,4-imino-D-arabinitol (DAB) or 1,4-dideoxy-1,4-imino-L-arabinitol ...
