celastrus kusanoi/neoplasms

In a search for revertants of multidrug-resistance in cancer cells, a novel (1) and two known (2,3) sesquiterpene esters were isolated from the root of Celastrus orbiculatus. The structure of 1 was elucidated as 1 beta,2 beta-diacetoxy-6 alpha,9 alpha-bis(benzoyloxy)dihydro-beta-agarofuran.

Gastric cancer is the fifth most common tumor and has the third-highest mortality rate among various malignant tumors, and the survival rate of patients is low. Celastrus orbiculatus extract has been shown to inhibit the activity of a variety of tumors. This study explored the inhibitory

OBJECTIVE To evaluate the effects of Celastrus Orbiculatus extracts (COE) on metastasis in hypoxia-induced hepatocellular carcinoma cells (HepG2) and to explore the underlying molecular mechanisms. METHODS The effect of COE (160, 200 and 240 μg/mL) on cell viability, scratch-wound, invasion and

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

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

OBJECTIVE Plants belonging to the genus Celastrus exhibit antitumor activity and the ability to reverse multidrug resistance in tumor cells; however, it remains unclear whether the compound oleanen from Celastrus hypoleucus also exhibits antitumor activity. The objective of this study was to explore

BACKGROUND Invasion of fibroblast-like synoviocytes (FLSs) is critical in the pathogenesis of rheumatoid arthritis (RA). The metalloproteinases (MMPs) and activator of nuclear factor-kappa B (NF-κB) pathway play a critical role in RA-FLS invasion induced by interleukin-1 beta (IL-1β) and tumour

Although angiogenesis inhibitors targeting VEGF/VEGFR2 have been applied for tumor therapy, the outcomes are still unsatisfactory. Thus, it is urgent to develop novel angiogenesis inhibitor for cancer therapy from new perspectives. Identification of novel angiogenesis inhibitor from natural products

BACKGROUND Cisplatin-based treatment often leads to therapeutic failure because the acquisition of cisplatin resistance. The combination of cisplatin with other agents has been recognized as a promising strategy to overcome cisplatin resistance. OBJECTIVE Celastrus orbiculatus is a traditional

Celastrus paniculatus is a traditional medicinal plant with diverse pharmacological activities. To identify its bioactive constituents, three new β-dihydroagarofuranoid sesquiterpenes were isolated from the whole plant, of which the major constituent is

Celastrus orbiculatus is used as a folk medicine in China for the treatment of numerous diseases. The ethyl acetate extract of Celastrus orbiculatus (COE) also displays a wide range of anti-cancer activities in the laboratory. However, the effectiveness of COE-induced autophagy and its mechanism of

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
