cynanchum atratum/抗がん剤

The root of Cynanchum auriculatum (C. auriculatum) Royle ex Wight has been shown to possess various pharmacological effects and has recently attracted much attention with respect to its potential role in antitumor activity. The C-21 steroidal glycosides are commonly accepted as the major active

The antitumor activities of six C-21 steroidal glycosides isolated from the root tuber of Cynanchum auriculatum Royle ex Wight were performed according to a microculture tetrazolium (MTT) method on human tumor cell lines SMMC-7721, MCF-7 and Hela. Of these compounds,

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

Antitumor activity of the ethanol extract from the root tuber of Cynanchum auriculatum Royle ex Wight and four fractions of the ethanol extract were investigated, both in vitro and in vivo. The five samples exhibited cytotoxic activity on human tumor cell lines K562, SHG44, HCT-8, A549, PC3, in

C21 steroidal glycoside (C21) is one of the most bioactive compounds of Cynanchum auriculatum Royle, known as Baishouwu, and possesses potent antitumor activity. Wilfoside C3N is one of the two most abundant and active C21 in it. The aim of this study was to further investigate the antitumor

An overwhelming endoplasmic reticulum stress (ERS) and the following unfolded protein response (UPR) can induce hepatic inflammation, fibrosis and hepatocellular carcinoma (HCC). Caudatin, one of the species of C‑21 steroidal glycosides mainly isolated from the roots of Cynanchum bungei Decne,

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.

A chemical investigation of Cynanchum mongolicum (Maxim.) Kom. identified 8 compounds. On the basis of spectroscopic data, they were determined to be 3 alkaloids and 5 sinapoyl esters, among which were two previously undescribed compounds (1 and 2). The inhibitory effects of the isolated compounds

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

C-21 steroids displayed the activities of immunosuppressive, anti-inflammatory and anti-virus effects by the reports. However, its antitumor effects and molecular mechanism remain unclear. We previously isolated and identified a C-21 steroidal glycoside (BW18) from the root of Cynanchum atratum

Glycosides are the bioactive components of many famous Chinese medicines. Here reported are some bioactive glycosides we discovered from Chinese medicines in recent years. (1) Phenolic glycosides from Chinese medicines: Gastrodia elata, Aconitum austroyunanense and Helicia erratica, three bioactive

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 present study aimed to investigate the anti-cancer effect of a C21-steroidal glycoside (CG) isolated from the roots of Cynanchum auriculatum. CG was able to inhibit the growth of human cancer cells (SGC-7901 cells) in a concentration and time-dependent manner in vitro. SGC-7901 cells exposed to
