Variable temperature NMR and modeling studies are consistent with the obtained biological data, since these studies confirmed that introduction at the N (4)-position of the piperazine ring allows productive interactions within the BACE-1 active site, which appear to be determinative for high BACE-1 inhibitory activity.

Thus, both MD and docking studies suggest that the role of hydrogen bond acceptor for the hydroxyl and piperazine groups of the inhibitors should be played by Asp228 instead of Asp32.
