In general, newcompounds scavenge free radical species, are predicted to be brain-permeable, andprotect neuronal cells against mitochondrial oxidative stress. N-(2-(1-Benzylpiperidin-4-yl)ethyl)-6,7-dimethoxy-4-oxo-4H-chromene-2-carboxamide (18) is highlighted dueto its interesting biological profile in σ1R, AChE, 5-LOX, MAO-A and MAO-B. Inphenotypic assays, it protects a neuronal cell line against mitochondrial oxidative stressand promotes maturation of neural stem cells into a neuronal phenotype, which couldcontribute to the reparation of neuronal tissues. Molecular modelling studies of 18 inAChE, 5-LOX and s1R revealed the main interactions with these proteins, which willbe further exploited in the optimization of new, more efficient DFHs PB Elsevier SN 0223-5234 YR 2018 FD 2018 LK http://hdl.handle.net/10347/32592 UL http://hdl.handle.net/10347/32592 LA eng NO Martín Estrada Valencia, Clara Herrera-Arozamena, Lucía de Andrés, Concepción Pérez, José A.
