]acetate (4) were synthesized and their characteristics were investigated. All of the novel derivatives were found to inhibit acetylcholinesterase obtained from Electrophorus electricus at a magnitude of one order less than that of the control tacrine. Derivatives 1–3 were found to be nontoxic towards human neuroblastoma SH-SY5Y cells, while compound 4 was markedly cytotoxic against these cells (IC50
