Starting from a structure-based drug design, new acetylcholinesterase inhibitors were designed and synthesized as analogues of donepezil. The compounds were composed by an aromatic function and a tertiary amino moiety connected by a suitable spacer. In particular, the benzophenone nucleus and the N,N-benzylmethylamine function were selected. The easily accessible three-step synthesis of these compounds resulted to be significantly less difficult and expensive than that of donepezil. Several compounds possess anti-cholinesterase activity in the order of micro and sub-micromolar. Particularly, compounds 1 and 10 were the most potent inhibitors of the series.
