euonymus americanus/neoplasms

A 46-year-old Korean woman was diagnosed with stage III breast cancer and underwent 8 cycles of neoadjuvant chemotherapy, breast conservation surgery and adjuvant radiotherapy. However, the cancer recurred in the right upper lung (RUL) and the right pulmonary hilum after 8 months. The RUL nodule was

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,

Fifteen new lupane-type triterpenoids (1-15) and 10 known triterpenoids (16-25) were isolated from the stems of Euonymus carnosus. The structures of the new compounds were elucidated on the basis of spectroscopic analyses, and the absolute configuration of compound 1 was confirmed by X-ray

In a previous paper [Cha, B.Y., Park, C.J., Lee, D.G., Lee, Y.C., Kim, D.W., Kim, J.D., Seo, W.G., Moon, S.K., Kim, C.H., 2003. Inhibitory effect of methanol extract from Euonymus alatus on matrix metalloproteinase-9, J. Ethnopharm. 85, 163-167], methanol extracts prepared from stems of Euonymus

Various extracts prepared from stems of Euonymus alatus were tested for cytotoxic activity on human hepatocellular carcinoma cell line, Hep3B cells using the XTT assay method. Also, the extracts were investigated the inhibitory effects on matrix metalloproteinase (MMP)-9 activity using gelatin

BACKGROUND Euonymus alatus (EA) has been used for tumor therapy. However, it is still unclear how this herb prevents the diseases in experimental models. Nitric oxide (NO) as a potent macrophage-derived effector molecule against a variety of tumors has received increasing attention. METHODS Using

Human myometrial smooth muscle cells (MSMC) showed high protein kinase C (PKC) activity when a maximal dose of PKC-activating phorbol ester was used, while uterine leiomyomal cells (ULMC) showed only 6-12% of PKC activity. MSMC exhibited a low proliferation rate, whereas ULMC exhibited a high

Euonymus alatus (E. alatus) is a medicinal plant used in some Asian countries for treating various conditions including cancer, hyperglycemia, and diabetic complications. This review outlines the phytochemistry and bioactivities of E. alatus related to antidiabetic actions. More than 100 chemical

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),

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

A new phenylpropanoid derivative (1), along with five phenylpropanoids (2-6), two monoepoxy lignans (8-9), one bisepoxy lignan (10), two cyclolignans (11-12), six neolignans (7, 13-17), two mixed lignan-neolignans (18-19), two lignan glycosides (20-21), and four flavonolignans (22-25), were isolated

A phenolic compound responsible for anti-MMP-9, which is known to be involved in tumor cell invasion and metastasis, has been isolated from methanol extracts prepared from stem barks of Euonymus alatus by assay-guided fractionation. The compound has been identified as 5-caffeoylquinic acid

To discover new pharmacologically active natural products, here, we performed the phytochemical analysis of a Korean medicinal plant. Euonymus alatus (Thunb.) Sieb. is a traditional medicinal plant that has been used as a remedy for various diseases in Asian countries. In particular, the cork
