In the course of screening for anti-dementia agents from natural products, two ${\beta}-secretase$ (BACE1) inhibitors were isolated from the methanolic extract of Perilla frutescens var. acuta and identified as luteolin (1) and rosmarinic acid (2) with $IC_{50}$ values of $5.0{\times}10^{-7}$ M and $2.1{\times}10^{-5}$ M, respectively. They inhibited BACE1 in a non-competitive manner with a substrate in Dixon plots, suggesting that they might bind to either ${\beta}-secretase$ subsite or to another regulatory site. Ki values of 1 and 2 were $6.2{\times}10^{-5}$ M and $3.9{\times}10^{-5}$ M, respectively. They were less inhibitory against other enzymes such as ${\alpha}-secretase$ (TACE), acetylcholine esterase (AchE), chymotrypsin, and elastase, indicating that they were relatively specific inhibitors of BACE1.
