OBJECTIVE To study the anti-tumor activity of extractive from Celastrus orbiculatus in vivo. METHODS Mice bearing transplanted tumor S180 and Heps were used to study the effects of acetoacetate and n-butanol extractive from C. orbiculatus. The changes in serum contents of SOD and malondialdehyde

OBJECTIVE Celastrus orbiculatus Thunb. has been used for thousands of years in China as a remedy against cancer and inflammatory diseases. This study aims to investigate whether C. orbiculatus extract (COE) could inhibit angiogenesis, which is the pivotal step in tumor growth, invasiveness, and

Celahypodiol 1, an unusual 17-membered carbon diterpenoid with a novel skeleton, and a new triterpenoid 12-oleanene-3beta,6alpha-diol 2, together with four known compounds furreginol 3, suigol 4, 20(30)-lupene-3beta, 29-diol 5, and 20(29)-lupene-1beta,3beta-diol 6, were isolated from the stalks of

Celastrus hindsii is a potential source of flavonoids with biological activities. This study aimed to develop an ultrasound-assisted technique for extracting flavonoids from leaves of C. hindsii. Response surface methodology was employed to optimize the extraction conditions for

BACKGROUND The traditional Chinese medicine (TCM) herb Celastrus orbiculatus is an important folk medicinal plant in China that has been used as an anti-inflammatory, antitumor, and analgesic in various diseases. The ethyl acetate extract of C. orbiculatus (C. orbiculatus extract, COE) was reported

OBJECTIVE To investigate the effects of novel triterpene (12-oleanene-3beta, 6alpha-diol) from Celastrus hypoleucus on the proliferation and apoptosis of human colorectal cancer cell line RKO. METHODS The inhibitory effect of the novel triterpene on RKO cell proliferation was assayed by MTT dye

A novel unusual 17-carbon diterpenoid, named (+)-7-deoxynimbidiol, was isolated from the stalks of Celastrus hypoleucus (Oliv.) Warb. Its racemate and derivatives were synthesized, and the inhibitory activities of these compounds against four cultured human-tumor cell lines were evaluated. The

The methanol extract of the stalks of Celastrus rosthornianus Loes. afforded a new fatty acid ester of triterpene: 1beta,3beta-dihydroxy-olean-9(11),12-dienyl-3-palmitate (1), and three known compounds beta-amyrin palmitate (2), 3beta-hydroxy-11-oxo-olean-12-enyl-3-palmitate (3) and lupeol palmitate

Four new triterpene compounds, celasdin-A, celasdin-C, anti-AIDS celasdin-B and cytotoxic maytenfolone-A, were isolated from Celastrus hindsii. The structural determination of maytenfolone-A, celasdin-A, celasdin-B and celasdin-C, as well as the structure-activity relationships of these new

Psoriasis is a chronic inflammatory skin disease affecting 1-3% of the world's population. Traditional Chinese medicines have been extensively used for treating psoriasis with promising clinical results. Celastrol, a triterpenoid isolated from a Chinese herb Celastrus orbiculatus caulis, has been

Three new sesquiterpene polyol esters with a beta-dihydroagarofuran skeleton, NW12 (1), NW27 (2), and NW31 (4), together with a known compound, NW30 (3), were isolated from the root bark of Celastrus angulatus. Their chemical structures were elucidated by analyses of MS and NMR spectral data.

OBJECTIVE Celastrus orbiculatus has been used as a folk medicine in China for the treatment of many diseases. In the laboratory, the ethyl acetate extract of Celastrus orbiculatus (COE) displays a wide range of anticancer functions. However, the inhibition of the metastasis mechanism of COE in

Recently, Celastrus orbiculatus ethyl acetate extracts (COE) have been investigated for their anticancer effects on digestive tract tumors. However, the therapeutic effects of COE on esophageal squamous carcinoma cells (ESCC) have not been investigated. In the present study, the effects of COE on

Celastrus orbiculatus Thunb has been known as an ethnopharmacological medicinal plant for antitumor, anti-inflammatory, and analgesic effects. Although various pharmacological studies of C. orbiculatus extract has been reported, an anti-inflammatory mechanism study of their

Celastrus orbiculatus extract (COE) has been used in folk medicine in China for the treatment of a number of diseases. In the laboratory, COE exhibits a variety of anticancer functions, including inhibition of metastasis. However, the underlying molecular anti-metastatic mechanism in nasopharyngeal
