Ingenol-3-angelate (Ing3A), extracted from Euphorbia peplus, is currently in clinical trials for eradicating basal cell carcinoma, actinic keratosis, and squamous cell carcinoma (SCC) in situ by topical application. Although structurally related to phorbol esters and a protein kinase C activator,
Malaria and Epstein-Barr virus (EBV), recognised cofactors for endemic Burkitt's lymphoma, are ubiquitous within the lymphoma belt of Africa, and, unless other cofactors are involved, the tumour should be much more common than it is. Malaria and EBV alone cannot account for the occasional shifting
Most cancer cells preferentially rely on glycolysis to produce the energy (adenosine triphosphate, ATP) for growth and proliferation. Emerging evidence demonstrates that the apoptosis in cancer cells could be closely associated with the inhibition of glycolysis. In this study, we have found that
Lung cancer is one of the most fatal cancers due to its high metastatic rate. Traditional Chinese medicine has been used in cancer patients for decades to improve quality of life and prolong survival time. The present study used a novel Qiyusanlong (QYSL) decoction composed of 10 kinds of Chinese
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
The latex of 'Crown-of-Thorns' (Euphorbia milii var. hislopii, syn. E. splendens) has been shown to be a potent plant molluscicide that could be used against the snails which are intermediate hosts of Schistosoma trematodes. However, a comprehensive toxicological evaluation of the latex is necessary
Jatrophane diterpenes were shown to be inhibitors of P-glycoprotein (P-gp). There are also evidences on their microtubule-interacting activity in cancer cells. We evaluated new anti-cancer characteristics of two jatrophane type compounds from Euphorbia dendroides. For that purpose, the model system
Diterpene esters of the phorbol and ingenol types are known to be highly active tumor promoting agents that typically occur in members of the Euphorbiaceae. In the present work, Euphorbia leuconeura, a rare indoor plant, is analyzed for its tumor promoting potential. Latex as well as total leaf
Irritant diterpene ester toxins were isolated from Euphorbia nubica and E. helioscopia, which are contaminants of the green fodder of livestock in Egypt. Fractionations of methanol extracts of aerial parts of both plants were monitored by the irritation unit on the mouse ear. Plant extracts were
Lactating goats were fed on aerial parts of the herb Euphorbia peplus L. admixed with their usual green fodder. During the experimental feeding period they showed symptoms of general poisoning. In necropsy the main toxic effects were seen in the heart, lung and liver. Histopathological examinations
The irritant and tumor-promoting constituents of latex of Euphorbia tirucalli L. originating from South Africa were isolated. They were identified as irritant ingenane and tigliane type diterpene esters derived from unsaturated aliphatic acids and acetic acid and the polyfunctional diterpene parent
Two new tetracyclic diterpene polyesters, euphoportlandols A (1) and B (2), have been isolated along with 12 known tetracyclic triterpenes from an acetone extract of Euphorbia portlandica. Their structures were established as
The diterpene ester ingenol-3-angelate (referred to as PEP005) is derived from the plant Euphorbia peplus. Crude euphorbia extract causes local toxicity and transient inflammation when applied topically and has been used in the treatment of warts, skin keratoses and skin cancer. PEP005 is a broad
OBJECTIVE
to evaluate the effect of the Euphorbia tirucalli hydroalcoholic extract (ETHE) on the development of Ehrlich Tumor, in its ascitic form.
METHODS
we intraperitoneally inoculated 15 Swiss mice with 10.44 x 107 cells of Ehrlich Tumor and divided them in two groups one day after: ETHE Group
Special procedures were developed to investigate poisonous milk of lactating goats fed experimentally on aerial parts of the herb Euphorbia peplus L. In extracts of the milk, weakly irritant in the mouse-ear assay, three diterpene ester toxins were detected by techniques of high-performance liquid
