Abstract

In the course of searching for anti-dementia agents from natural products, loganin isolated from EtOAc fraction of Corni fructus possessed specific inhibitory activity against βsecretase (BACE1) with 9.2 × 10 ^-5M and Ki value of 5.5 × 10 ^-5 M. Loganin exhibited less inhibitory activity to β-secretase (TACE) and other serine proteases exhibiting that it was a relatively specific inhibitor of BACE1. These novel findings suggest that loganin may be used to attenuate the progression and/or prevention of Alzheimer's disease.
