In this study, we focused the effects of crebanine, an alkaloid isolated from the tuber of Stephania venosa, on various human cancer cells. Crebanine treatment was found to significantly inhibit the proliferation of human leukemic cells (HL-60, U937 and K562), human fibrosarcoma cells (HT1080) and
The alkaloids isolated from Stephania venosa (S. venosa) have been shown to inhibit the proliferation and to induce the apoptosis of cancer cells. However, the anti-metastatic effect of the alkaloids on cancer cell invasion is unknown. In this study, we investigated the anti-invasive properties of
Stephania venosa (Blume) Spreng or "Sa-Bu-Leud" is a Thai medicinal plant used for treatment of cancer and diabetes, and as a blood-tonic and aphrodisiac. This plant .ontains alkaloids as its major components and has been of interest for its acetylcholinesterase (AChE) inhibitory activity.
The cytotoxic activity of five alkaloids, namely 4,5-dioxo-dehydrocrebanine (1), dehydrocrebanine (2), crebanine (3), oxostephanine (4), and thailandine (5) isolated from the tuber and leaves of Stephania venosa (Blume) Spreng was investigated. Thailandine showed the strongest activity against lung
Extracts from the tubers of Stephania venosa (Blum) Spreng growing in Vietnam significantly inhibited cell proliferation against a number of cancer cells including HeLa, MDA-MB231 and MCF-7 cells. A bioassay-guided fractionation led to the isolation of four aporphine and one tetrahydroprotoberberine
Crebanine (CN), tetrahydropalmatine (THP), O-methylbulbocapnine (OMBC) and N-methyl tetrahydropalmatine (NMTHP) are isoquinoline derived natural alkaloids isolated from tubers of Stephania venosa. We investigated chemo-sensitizing effects of these alkaloids in ovarian cancer cells and evaluated
The natural aporphine alkaloids including crebanine (CN), O-methylbulbocapnine (OMP), and dicentrine (DC), and protoberberine alkaloids, tetrahydropalmatine (THP) and N-methyl tetrahydropalmatine (NTHP), have been found in Stephania venosa. Previous reports demonstrated CN and THP exhibited
