Abstract

Sophopterocarpan A (1), with a novel benzotetrahydrofuran-fused bicyclo [3.3.1] nonane ring, was isolated from the roots of Sophora flavescens Ait. Its unusual structure, including its stereochemistry, was determined on the basis of a comprehensive spectroscopic data analysis. A plausible biogenetic pathway for 1 is presented. Sophopterocarpan A was identified as a potential autophagy activator. Additionally, it was found that 1 exhibited cytotoxic activity in MCF-7 cells with an IC50 of 29.36 μM.
