Novel inhibitors of cholinesterases, especially butyrylcholinesterase ( B u C h E ), were obtained by coupling melatonin–tacrine heterodimers via the carbamate bond. Compounds 14a‐i possessed potent cholinesterase inhibitory activity (with IC 50 values as low as 1.18 n m for acetylcholinesterase ( AC h E ) and 0.24 n m for butyrylcholinesterase ( B u C h E )). These heterodimers exhibit selectivity toward B u C h E , being from 4‐ to 256‐fold more active toward B u C h E than AC h E , but still acting as better AC h E inhibitors than tacrine 4 .
