Osthole has been reported to have antitumor activities via the induction of apoptosis and inhibition of cancer cell growth and metastasis. However, the detailed molecular mechanisms underlying the anticancer effects of osthole in human colon cancer remain unclear. In the present study, we have assessed osthole-induced cell death in two different human colon cancer cell lines, HCT116 and SW480. ...

Osthole is an active compound isolated from Chinese herb Cnidium monnieri (L.) Cusson, and had been reported to possess antitumor effect. However, the effect of osthole on the gastric cancer cells has not been investigated. In this study, the effects of osthole on the proliferation of human gastric cancer cells were tested. The data showed that osthole treatment significantly inhibited the prol...

Osthole, a coumarin compound, has been reported to exhibit various biological activities; however the cellular mechanism of its immune modulating activity has not yet been fully addressed. In this study we isolated osthole from the seeds of Cnidium monnieri and demonstrated that osthole inhibited TNF-α, NO and COX-2 expression in LPS-stimulated macrophages, without reducing the expression of IL...

The survival of osteoblast cells is one of the determinants of the development of osteoporosis in patients. Osthole (7-methoxy-8-isopentenoxycoumarin) is a coumarin derivative present in many medicinal plants. By means of alkaline phosphatase (ALP) activity, osteocalcin, osteopontin, and type I collagen, enzyme-linked immunosorbent assay, we have shown that osthole exhibits a significant induct...

Intestinal ischemia/reperfusion (I/R) injury is considered to be associated with high morbidity and mortality rates. Osthole, a natural derivative of coumarin, has been shown to exert a variety of pharmacological and therapeutic effects under physiological and pathological conditions. In the present study, to investigate the protective effects of osthole against intestinal I/R injury, various d...

Osthole, an active coumarin isolated from Cnidium monnieri (L.) Cusson, has long been used in China as an antipruritic herbal medicine; however, the antipruitic mechanism of osthole is unknown. We studied the molecular mechanism of osthole in histamine-dependent itch by behavioral test, Ca(2+) imaging, and electrophysiological experiments. First, osthole clearly remitted the scratching behavior...

Anabolic anti-osteoporotic agents are desirable for treatment and prevention of osteoporosis and fragility fractures. Osthole is a coumarin derivative extracted from the medicinal herbs Cnidium monnieri (L.) Cusson and Angelica pubescens Maxim.f. Osthole has been reported with osteogenic and anti-osteoporotic properties, whereas the underlying mechanism of its benefit still remains unclear. The...

OBJECTIVE To explore the effect of Osthole on protecting myocardial cell apoptosis induced by doxorubicin during cardiac failure in rats. METHODS Myocardial cells isolated from the newborn SD rats were separated into three groups: cells treated with 1 μmol doxorubicin, cells treated with Osthole at three concentrations of 10, 20, and 40 μmol, cells treated neither with Osthole nor with doxoru...

The purpose of this study was to examine effects of osthole on postmenopausal osteoporosis using ovariectomized (OVX) rats. All of the rats were divided into sham and OVX groups. At 2 weeks post-operation, the sham-operated rats received solvent vehicle (97% corn oil and 3% ethanol, 1.0 ml/kg, subcutaneously); the OVX rats were divided into three groups which were treated with solvent vehicle (...

BACKGROUND To explore the effects of Osthole on the proliferation, cell cycle and apoptosis of human lung cancer A549 cells. METHODS Human lung cancer A549 cells were treated with Osthole at different concentrations. Cell proliferation was measured using the MTT assay. Cell cycle was evaluated using DNA flow cytometry analysis. Induction of apoptosis was determined by flow cytometry and fluor...
