cynanchum otophyllum/neoplasms

OBJECTIVE To investigate the inhibition of three C2 steroidal saponins from Cynanchum auriculatum on the cell growth and cell cycle of human lung cancer A549 cells. METHODS A549 cells were exposed to three C21 steroidal saponins of different concentrations (5, 10, 20, 40, 60, 80, 100 micromol L(-1))

Caudatin 3-O-β-D-cymaropyranosyl-(1 → 4)-β-D-oleandropyranosyl-(1 → 4)-β-D-cymaropyranosyl-(1 → 4)-β-D-cymaropyranoside (CGII) is one of the C21-steroidal glycosides isolated from the roots of Cynanchum auriculatum ROYLE ex WIGHT. This study aimed to determine the cell growth, cell proliferation,

In the complex tumor microenvironment, cancer stem cells (CSCs), a rare population of cells, are responsible for malignant tumor initiation, metastasis, drug resistance and recurrence. Controlling breast CSCs (BCSCs) using natural compounds is a novel potential therapeutic strategy for clinical

OBJECTIVE To investigate whether Paeotang (10-50 μg/mL) suppresses tumor necrosis factor α (TNF-α)-induced vascular inflammatory processes in human umbilical vein endothelial cells (HUVEC). METHODS The ingredients composed of Paeotang include Glycyrrhiza glabra, Zingiber officinale, Cinnamomum

Cynanchum wallichii Wight, is a traditional Chinese medicine herb, which is rich in saponins and has varieties of pharmacological activities. In this study, a standardized C. wallichii extract was established and the anti-tumor activity of the total saponins was evaluated by MTT assay. The

Wilfoside K1N is a polyoxypregnane glycoside isolated from Cynanchum wilfordii (Asclepiadaceae). Polyoxypregnane glycosides are associated with cellular immunity and anti-tumor activity, and increase the cytotoxicity of many anti-cancer drugs showing multidrug resistant activity on tumor cells. In

The C21-steroidal glycoside auriculoside A (1), recently isolated from the roots of Cynanchum auriculatum, was found to inhibit the growth of several human tumor cell lines and to induce apoptosis in human breast cancer (MCF-7) cells. Compound 1 was evaluated for its in vitro cytotoxicity against

Two known phenanthroindolizidine alkaloids, (-)-(R)-13aalpha-antofine (1) and (-)-(R)-13aalpha-6-O-desmethylantofine (2), and two new natural products, (-)-(R)-13aalpha-secoantofine (3) and (-)-(R)-13aalpha-6-O-desmethylsecoantofine (4), were isolated from Cynanchum vincetoxicum. The structures of

Two new steroidal glycosides characterized with 2,6-dideoxypyranoses as component sugars have been isolated from roots of Cynanchum wallichii Wight. Their structure elucidation and cytotoxic activities against HL-60 and PC-3 cells are reported.

We recently reported the immune-enhancing effects of a high-molecular-weight fraction (HMF) of CW in macrophages and immunosuppressed mice, and this effect was attributed to a crude polysaccharide. As polysaccharides may also have anti-inflammatory functions, we investigated the anti-inflammatory

Two new pregnane glycosides, kidjoranin 3- O- alpha-diginopyranosyl-(1-->4)- beta-cymaropyranoside (1) and kidjoranin 3-O-beta-digitoxopyranoside (2), together with one known compound caudatin 3 -O-beta-cymaropyranoside (3), were isolated from the roots of Cynanchum auriculatum. Their structures

Fourteen new pregnane glycosides, including nine caudatin glycosides (1-9), three qinyangshengenin glycosides (10-12), one kidjoranin glycosides (13) and one gagaminin glycosides (14), along with twelve known analogs (15-26) were isolated from roots of Cynanchum otophyllum Schneid. Their structures

Eight new C21 steroidal glycosides, namely cynanotins A-H (1-8), together with fifteen known analogues, were isolated from the roots of Cynanchum otophyllum. Their structures were elucidated by spectroscopic analysis and chemical methods. In this study, all of isolates were tested for their vitro

A novel biphenylneolignan, 2,6,2',6'-tetramethoxy-4,4'-bis(2,3-epoxy-1-hydroxypropyl)biphenyl (1), and two new glycosides named atratoglaucosides A (2) and B (3), were isolated from the roots of Cynanchum atratum, and their structures were determined on the basis of chemical and spectroscopic
