Three-Membered Ring Sesquiterpenoids with NGF-Potentiating Activity from the Roots of Valeriana fauriei

Abstract

Three novel three-membered ring sesquiterpenoids, named kissoone A (1), kissoone B (2), and its acetylated product, kissoone C (3), were isolated from the roots of Valeriana fauriei. Their structures were elucidated on the basis of spectroscopic analysis. Compounds 2 and 3 showed enhancing activity on nerve growth factor (NGF)-mediated neurite outgrowth in PC 12D cells.
