AbstractHerein we describe the synthesis and <i>in vitro</i> biological evaluation of thirteen new, racemic, diversely functionalized <i>imidazo pyranotacrines</i> as non-hepatotoxic, multipotent tacrine analogues. Among these compounds, 1-(5-amino-2-methyl-4-(1-methyl-1<i>H</i>-imidazol-2-yl)-6,7,8,9-tetrahydro-4<i>H</i>-pyrano[2,3-<i>b</i>]quinolin-3-yl)ethan-1-one (4) is non-hepatotoxic (cell viability assay on HepG2 cells), a selective but moderately potent <i>Ee</i>AChE inhibitor (IC<sub>50</sub> = 38.7 ± 1.7 μM), and a very potent antioxidant agent on the basis of the ORAC test (2.31 ± 0.29 μmol·Trolox/μmol compound).
