Prolyl endopeptidase (PEP, EC 3.4.21.26) is an enzyme to play a role in metabolism of proline-containing neuropeptides, such as vasopressin, substance P and thyrotropin-releasing hormone (TRH), which were suggested to be involved with learning and memory processes. Then, specific inhibitor of PEP is expected to have antiamnesic effects, and thus we screened forty-six water- and methanol-extracts from crude drugs selected on the basis of traditional Chinese medicine theory, for Flavobacterium prolyl endopeptidase inhibition. Among them, the water-extracts of Rhodiola sacra (IC50, 0.77 microgram/ml) and the methanol-extracts of Lycopodium clavatum (IC50, 1.3 micrograms/ml), Paeonia lactiflora var. trichocarpa (IC50, 5.7 micrograms/ml), Paeonia veitchii (IC50, 2.4 micrograms/ml) and Rhodiola sacra (IC50, 0.67 microgram/ml) showed strong inhibitory activity. In addition, we also examined the PEP inhibitory activity of eleven compounds from Salvia deserta, and found that in addition to a catechol group alpha-hydroxy-para-quinone group may be related to the PEP inhibition.
