Neochamaejasmin A ( 1), a biflavonoid isolated from the roots of a traditional Chinese medicine, Stellera chamaejasme L., was shown to inhibit cellular (3)H-thymidine incorporation (IC 50 12.5 microg/mL) and subsequent proliferation of human prostate cancer LNCaP cells. Treatment of LNCaP cells with
OBJECTIVE
To investigate the inhibitory and pro-apoptotic effect of Stellera Chamaejasme L extract (ESC) in vitro.
METHODS
ESC was first extracted with ethanol, and then washed using a polyamide column with 60% ethanol. ESC was then decompressively recycled and vacuum dried at room temperature to
Six 3,3″-biflavanones, including a new compound isochamaejasmenin C (1), were isolated from EtOH extracts of the roots of Stellera chamaejasme L. Their structures were elucidated on the basis of spectroscopic methods, including HR-ESI-MS and 2D NMR techniques. The absolute configurations on 2, 3,
BACKGROUND
Epithelial mesenchymal transition (EMT) mediated by TGF-β pays an important role in malignant tumor acquired abilities of migration and invasion. Our previous study showed that the extract of Stellera chamaejasme L. (ESC) was against proliferation of a variety of tumor cells, but there
OBJECTIVE
To examine the anti-cancer effects of chamaejasmenin B and neochamaejasmin C, two biflavonones isolated from the root of Stellera chamaejasme L (known as the traditional Chinese herb Rui Xiang Lang Du) in vitro.
METHODS
Human liver carcinoma cell lines (HepG2 and SMMC-7721), a human
BACKGROUND
Stellera chamaejasme L, a traditional Chinese herb, has long been used for treatment of various tumors in the Chinese population. In our previous study, we paid an attention to the cytotoxic and proapoptotic effects of Stellera chamaejasme L extracts (ESC, ESC-1 and ESC-2, the latter two
OBJECTIVE
To observe the anti-tumor effect of alcohol extract of Stellera chamaejasme-AESC, AESC-1 and AESC-2 in vitro.
METHODS
Inhibition rates of AESC, AESC-1, AESC-2 on five tumor cells (A549, NCI-H157, NCI-H460, BEL-7402 and SK-HEP-1 cell lines) were observed and IC50, GI50, TGI50 and LC50 were
Stellera chamaejasme L. has been widely used in the treatment of lung, liver and esophageal cancer in Chinese traditional medicine. In our previous study, we found that the extract of Stellera chamaejasme L. (ESC) inhibited the growth and induced the apoptosis of human lung cancer NCI-H157 cells. In
Metastasis is the leading lethal factor severely restraining the effectiveness of clinical treatment. TGF-beta is the key regulator for metastasis and influences paradoxically on cancer progression. The known TGF-beta blockers exert little selectivity on its functions, indiscriminately causing the
The neovascularization functions essentially for malignant upgrading and predicts poor prognosis in multiple cancers, which make it the highly effective strategy for clinical treatment. Unfortunately, the known anti-angiogenic therapies show low effectiveness against breast cancer. Recently,
OBJECTIVE
To in vitro compare the induction of extracts of Stellera chamaejasme ESC, ESC-1 and ESC-2 on NCI-H157 cell apoptotic.
METHODS
The apoptosis rate was inspected by flow cytometry; caspase-3, 8, 9 activities was measured by spectrophotometry. Fas, Fas-L, TNF-alpha, Trail-R, Cyto-C,
Stellera chamaejasme L. (Thymelaeaceae) is a perennial herb that is widely used in traditional Chinese medicine to treat tumours, tuberculosis and psoriasis. S. chamaejasme extract (SCE) possesses anti-inflammatory, analgesic and wound healing activities; however, the effect of S. chamaejasme and
Chamaechromone and neochamaejasmin B (NCB) are the most abundant components in the dried roots of the toxic perennial herb Stellera chamaejasme L. and have pharmacological activities. The objective of this study was to investigate the transport mechanism of these two components in vivo and in vitro.
Two new glycoglycerolipids (1 and 2), along with three known compounds (3-5) were isolated from Stellera chamaejasme. The structure of the new compounds was elucidated by chemical and spectroscopic data analysis. The cytotoxic activity of 1-3 was evaluated and showed no activity against the assayed
