Comprehensive Summary

A novel schinortriterpenoid (SNT), schinensilactone A (1), characterized by a unique 7,8-seco-1,8-cyclo-schisanartane scaffold, was isolated from the leaves of Schisandra chinensis (Turcz.) Baill, together with a new SNT (schinensilactone B, 2) and two known (3, 4). Their structures were elucidated using spectroscopy and X-ray diffraction. Furthermore, a hypothetical biosynthetic pathway for 1 was postulated due to its novel carbon skeleton. In addition, 1 exhibited significant anti-proliferative activity against Caco-2 cells originating from five different tumor cell lines, and its preliminary mechanism of action was investigated with respect to the expression of apoptosis-related proteins, including P53, Caspase 3, Bax, PUMA, and Bcl2. These biological activities would further our understanding of the food function of Schisandra chinensis leaves. image
