BACKGROUND
Breast cancer is the leading cause of cancer-related death among women worldwide. For treating breast cancer, numerous natural products have been considered as chemotherapeutic drugs.
OBJECTIVE
The present study aims to investigate the apoptotic effect of Saxifragifolin A (Saxi A)
Breast cancer is currently the most common form of cancer affecting women. Recent studies have reported that triterpenoid saponins isolated from Androsace umbellata exhibit anti-proliferative effects in several types of cancer cells. However, the cytotoxic effect of saxifragifolin C (Saxi C) on
Breast cancer is the leading cause of cancer death among females, and novel chemotherapeutic drugs for treating breast cancer are needed urgently. Saxifragifolin D (SD) was isolated by our group from Androsace umbellata which is commonly used to treat solid tumor. In this study, we evaluated its
BACKGROUND
Afrocyclamin A, an oleanane-type triterpene saponin, was isolated from Androsace umbellata which used as a traditional herbal medicine.
OBJECTIVE
This study aimed to explore the anticancer activity of afrocyclamin A on human prostate cancer cells in vitro as well as in
Cytotoxicity-guided fractionation and separation of MeOH extract from Androsace umbellata (Lour.) Merr. led to the isolation of four triterpenoid saponins. Compounds isolated from the n-BuOH soluble fraction were identified as saxifragifolin C (1), A (2), B (3), and D (4) by spectroscopic analysis.
Bioassay-guided phytochemical study of Androsace umbellata led to the successful isolation of saxifragifolin B (SB) for the first time. The anti-tumor effect of SB was firstly reported that it was shown to have potent cytotoxicity on human hepatoma HepG2 cells with IC50 value of 11.9 microM at 24 h.
A new triterpene saponin, androsacin (1), along with two known compounds, ardisiacrispin A (2) and saxifragifolin A (3), were isolated from the whole plants of Androsace integra. The chemical structure of the new compound was elucidated as
