摘要
To research a new non-peptidyl inhibitor of beta-site amyloid precursor protein cleaving enzyme 1, we focused on the curcumin framework, two phenolic groups combined with an sp(2) carbon spacer for low-molecular and high lipophilicity. The structure-activity relationship study of curcumin derivatives is described. Our results indicate that phenolic hydroxy groups and an alkenyl spacer are important structural factors for the inhibition of beta-site amyloid precursor protein cleaving enzyme 1 and, furthermore, non-competitive inhibition of enzyme activity is anticipated from an inhibitory kinetics experiment and docking simulation.
