triterpene/悪性腫瘍

In this research, aerial parts of Euphorbia denticulata Lam were collected from Sanandaj city in Kurdistan province at the West of Iran. It was extracted by maceration using acetone as solvent. The isolation of compounds were carried out with repeated column chromatography using silica gel and

Investigation of the hooks of Uncaria rhynchophylla resulted in isolation of six phospholipase Cgamma1 (PLCgamma1) inhibitors (1-6). The structures of these compounds were elucidated as pentacyclic triterpene esters by spectroscopic and chemical analysis. Three of them, namely uncarinic acids C (1),

The modulating effect of Lupeol [lup-20(29)-en-3 beta -ol], a triterpene found in many fruits and medicinal plants, on benzoyl peroxide-induced tumor promotion responses or tumor promotion in murine skin is described. Benzoyl peroxide is an effective cutaneous tumor promoter acting through the

Complementary treatment possibilities for the therapy of cancer are increasing in demand due to the severe side effects of the standard cytostatics used in the first-line therapy. A common approach as a complementary treatment is the use of aqueous extracts of Viscum album L. (Santalaceace). The

Arjunolic acid, an oleanene-type triterpene isolated from the rhizome of Cochlospermum tinctorium, its triacetate derivative, and their methyl esters were tested using the short-term in vitro assay on EBV-EA activation in Raji cells induced by 12-O-tetradecanoyl-phorbol-13-acetate (TPA). Their

The pentacyclic triterpene 3β,6β,16β-tri-hydroxilup-20(29)-ene is a natural product produced by the Brazilian medicinal plant Combretum leprosum. Its cytotoxicity has been previously reported against breast cancer cell lines. The low water solubility of this natural product, that hampers its

Among the classes of identified natural products, triterpenoids, one of the largest families, have been studied extensively for their diverse structures and variety of biological activities, including antitumor effects. In the present study, a phytochemical study of the green walnut husks of Juglans

Triterpene saponins are secondary metabolites typical for higher plants. They possess a wide range of pharmaceutical and biological activities. These include anti-inflammatory, vasoprotective, expectorant, and antitumor properties. In particular, the ability of saponins to enhance the cytotoxicity

Ganoderma lucidum, within the Polyporaceae family of Basidiomycota, is a popular traditional remedy medicine used in Asia to promote health and longevity. Compounds extracted from G. lucidum have revealed anticancer, antioxidant and liver protective effects. G. lucidum has been associated with

We previously reported that the antiproliferative effect of an isopropanolic-aqueous extract of black cohosh (iCR) on MCF-7 estrogen-responsive breast cancer cell line was due to the induction of apoptosis. Here we address the question to what extent apoptosis induction can be ascribed to one of the

Neither androgen ablation nor chemotherapeutic agents are effective in reducing the risk of prostate cancer progression. On the other hand, multifaceted effects of phytochemicals, such as triterpene saponins, on cancer cells have been suggested. A promising safety and tolerability profile indicate

Problem statement: Clinicanthus nutans has been used by Malaysian since long time ago. It is used to treat manydiseases including cancer. Many studies carried out on its crude extract but no clear report on the specific secondarymetabolites responsible for its nature in treating selected diseases.

Recently we showed Lupeol, a triterpene, found in fruits and vegetables inhibits the growth of tumors originated from human androgen-sensitive prostate cancer (CaP) cells and decreases the serum-PSA levels in a mouse model. Here, we provide evidence that Lupeol inhibits the growth of

Sipholenol A, a sipholane triterpene isolated from the Red Sea sponge Callyspongia siphonella, has the ability to reverse multidrug resistance in cancer cells that overexpress P-glycoprotein (P-gp). Here, the antimigratory activity of sipholenol A and analogues are reported against the highly
