Seven constituents were isolated from the ethyl acetate extract of the rhizome of Cynanchum otophyllum Schneid (Asclepiadaceae). Their structures were determined as 1-(4-methoxy-3-(6-methoxy-3-acetylphenylperoxy)phenyl)ethanone (1), 1-(3-hydroxy-7-acetylnaphthalen-2-yl)ethanone (2),
Two new pregnane glycosides, kidjoranine 3-O-β-D-glucopyranosyl-(1 → 4)-β-D-glucopyranosyl-(1 → 4)-α-L-cymaropyranosyl-(1 → 4)-β-D-cymaropyranosyl-(1→4)-α-L-diginopyranosyl-(1 → 4)-β-D-cymaropyranoside (5) and caudatin 3-O-β-D-glucopyranosyl-(1 → 4)-β-D-glucopyranosyl-(1 → 4)-α-L-cymaropyranosyl-(1
The antifungal activities of eleven C21-steroidal compounds isolated from Cynanchum wilfordii, together with thirty-six derivatives of caudatin and qingyangshengenin were evaluated on Sclerotinia sclerotiorum and other five fungal strains by the mycelium growth rate method. Four derivatives 1k, 1y,
BACKGROUND
Cynanchum komarovii Al Iljinski is a desert plant that has been used as analgesic, anthelminthic and antidiarrheal, but also as a herbal medicine to treat cholecystitis in people. We have found that the protein extractions from C. komarovii seeds have strong antifungal activity. There is
We previously reported that seven pregnane glycosides including cynatroside B isolated from the roots of Cynanchum atratum significantly inhibited acetylcholinesterase (AChE) activity. In the present study, we have characterized the mode of AChE inhibition of cynatroside B, the most potent of these
The menopausal syndrome caused by rapid changes in hormone levels greatly influences the quality of life of women. Though hormone replacement therapy (HRT) is widely used to treat the menopausal syndrome, it exhibits many side effects, including the risk of thrombosis, cardiovascular diseases, and
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
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
Cynanchum bungei Decne. (CB) (Asclepiadaceae) and its two related species Cynanchum auriculatum Royle ex Wight. (CA) and Cynanchum wilfordii (Maxim.) Hemsl. (CW) are well known Chinese herbal medicines known by the name Baishouwu. Among them, CB has long been used for nourishing the Ischemic stroke is the third leading cause of death in the world. Our previous study found that cynandione A (CYNA), the main component from the root of Cynanchum bungei, exhibits anti-ischemic stroke activity. In this work, we investigated the therapeutic mechanisms of CYNA to ischemic stroke at
The ability of tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) to preferentially induce apoptosis in transformed cells while sparing most normal cells is well established. However, the intrinsic and acquired resistance of tumors to TRAIL-induced apoptosis limits its Ethnopharmacological relevance: Irritable bowel syndrome (IBS) is a chronic, stress-related, functional gastrointestinal disorder characterized by abdominal discomfort and altered bowel habits; the manipulation of the microbiota is
The present study was conducted to isolate anti-inflammatory compound from Cynanchum atratum and investigate the molecular mechanisms of active compound against lipopolysaccharide (LPS)-induced mastitis in mice. Bioassay-guided fractionations and isolation (via ex vivo tests) of compounds with
