Six new dihydro-beta-agarofuran [5,11-epoxy-5beta,10alpha-eudesm-4 (14)-ene] sesquiterpenes were isolated from the seeds of Euonymus nanoides Loes, including five with a novel substitution pattern: (1 R,2 S,4 S,5 R,7 R,9 S,10
Epicatechin (EC) is the most effective compound in Euonymus alatus (Thunb.)Sieb, and possesses a series of benefits, including anti-inflammatory, antioxidant, antiobesity and anticancer effects. In this study, we investigated the protective effects of EC in Acetaminophen(N-acetyl-p-aminophenol,
To investigate the chemical compounds from the twigs of Euonymus alatus, nine compounds were isolated and identified as(+)-delta(2,11)-enaminousnic acid(1), 11-keto-beta-boswellic acid(2), acetyl 11-keto-beta-boswellic acid(3), camaldulenic acid(4), betulinic acid(5),
OBJECTIVE
To study the chemical constituents and antitumor activities of Euonymus alatus.
METHODS
Compounds were isolated and purified repeatedly by silica gel, Sephadex LH-20 column chromatography, and their chemical structures were elucidated by their physicochemical properties and spectral data,
The excessive and prolonged nitric oxide (NO) production has been linked to various inflammatory diseases as well as tumourigenesis. On the search for anti-inflammatory and anti-cancer compounds from the medicinal plants, the methanolic extract of Euonymus alatus (Thunb.) Sieb. (Celastraceae) was
Euonymus alatus (Thunb.) Sieb (EA) is a traditional Korean herbal medicine, commonly used to treat tumors in Korea and China for centuries. Our earlier studies have indicated that EA exhibits antitumor properties, but its mechanism remains to be elucidated. In this study, we evaluated the molecular
BACKGROUND
The transcription factor signal transducer and activator of transcription 3 (Stat3) is constitutively activated in many human cancers. It promotes tumor cell proliferation, inhibits apoptosis, induces angiogenesis and metastasis, and suppresses antitumor host immune responses. Therefore,
Two new beta-dihydroagarofuran sesquiterpene polyesters, 1S,13-diacetyloxy-4S-hydroxy-6R-(3-)furancarbonyloxy-9S-cinnamoyloxy-beta-dihydroagarofuran (1) and 1S,6R-di(2-)methylbutanoyloxy-4S-hydroxy-8S-benzoyloxy-9R-(3-)furancarbonyloxy-13-acetyloxy-beta-dihydroagarofuran (2), together with one known
Ethnopharmacological relevance: Euonymus alatus (Thunb.) Siebold (E. alatus), a well-known medicinal plant, has been widely used thousands of years in China for the treatment of various diseases such as urticaria, dysmenorrhea, wound,
Euonymus alatus (Celastraceae) has been used as an anticancer agent in Korean traditional medicine. However, the potential bioactive contributors to the anticancer effects have not been thoroughly studied. Our screening test revealed that the MeOH extract of E. alatus twigs exhibited significant
The aim of this investigation was to study the antioxidant and anticancer activities of young sprouts of some traditional Korean salad plants. Total phenolics, antioxidant and anticancer activities of the methanol extracts from young sprouts of 11 salad plants were determined. The highest amount of
Our previous studies have clearly shown that the angiogenic enzymes, matrix metalloproteinase (MMP) -2/9, are directly involved in human hepatic tumorigenesis and metastasis and suggest that the MMP-2/9 inhibitors, which have dual inhibitory activities on enzyme activity and transcription, represent
The development of strategies intended to inhibit human cytomegalovirus (HCMV) immediate-early (IE) antigen expression is an important goal in research designed to prevent and treat certain forms of cancer. The aim of this study was to identify potent IE antigen-targeting natural compounds as
Matrix metalloproteinase-9 (MMP-9) degrades type IV collagen constituting the major structural component of the basement membrane and extra cellular membrane. The enzymatic activity is found to be elevated in tumor tissues. With the aim of finding novel MMP-9 inhibitors from natural products, 87
