Natural health products that inhibit angiogenesis: a potential source for investigational new agents to treat cancer-Part 2.

Numai utilizatorii înregistrați pot traduce articole

The herbalist has access to hundreds of years of observational data on the anticancer activity of many herbs. Laboratory studies are expanding the clinical knowledge that is already documented in traditional texts. The herbs that are traditionally used for anti-cancer treatment and that are

Natural health products that inhibit angiogenesis: a potential source for investigational new agents to treat cancer-Part 1.

Numai utilizatorii înregistrați pot traduce articole

An integrative approach for managing a patient with cancer should target the multiple biochemical and physiologic pathways that support tumour development and minimize normal-tissue toxicity. Angiogenesis is a key process in the promotion of cancer. Many natural health products that inhibit

Chemical constituents from Artemisia vulgaris and their antiausterity activities against the PANC-1 human pancreatic cancer cell line.

Numai utilizatorii înregistrați pot traduce articole

The 70% ethanolic extract of Artemisia vulgaris showed preferential cytotoxicity against PANC-1 human pancreatic cancer cells under a nutrient-deprived condition with PC₅₀ 12.5 μg/mL. A phytochemical investigation of this extract yielded a new bicyclic [4:3:0] sesquiterpene named

Artemisia princeps var orientalis induces apoptosis in human breast cancer MCF-7 cells.

Numai utilizatorii înregistrați pot traduce articole

BACKGROUND Dried leaves of Artemisia princeps var orientalis are used in the Eastern practice of moxibustion to improve general health. The ability of A. princeps smoke and water extracts to induce apoptosis was evaluated in human breast cancer MCF-7 cells in vitro. METHODS Tumor cells were cultured

Standardized flavonoid-rich fraction of Artemisia princeps Pampanini cv. Sajabal induces apoptosis via mitochondrial pathway in human cervical cancer HeLa cells.

Numai utilizatorii înregistrați pot traduce articole

BACKGROUND Artemisia princeps Pampanini is widely used in Eastern traditional medicine for the treatment of circulatory disorders, such as, dysmenorrhea, hematuria, hemorrhoids, and inflammation, and is also used to treat chronic conditions, such as, cancers, ulcers, and digestive

Synthesis and anti-cancer activity of covalent conjugates of artemisinin and a transferrin-receptor targeting peptide.

Numai utilizatorii înregistrați pot traduce articole

Artemisinin, a natural product isolated from Artemisia annua L., shows a unique anti-cancer activity by an iron dependent mechanism. Artemisinin was covalently conjugated to a transferrin-receptor targeting peptide, HAIYPRH that binds to a cavity on the surface of transferrin receptor. This enables

Comparative cytotoxicity of artemisinin and cisplatin and their interactions with chlorogenic acids in MCF7 breast cancer cells.

Numai utilizatorii înregistrați pot traduce articole

In parts of Africa and Asia, self-medication with a hot water infusion of Artemisia annua (Artemisia tea) is a common practice for a number of ailments including malaria and cancer. In our earlier work, such an extract showed better potency than artemisinin alone against both chloroquine-sensitive

In vitro evaluation of the cytotoxic and genotoxic effects of artemether, an antimalarial drug, in a gastric cancer cell line (PG100).

Numai utilizatorii înregistrați pot traduce articole

Artemisinin is a sesquiterpene lactone endoperoxide, obtained from Artemisia annua, and extensively used as an antimalarial drug. Many studies have reported the genotoxic and cytotoxic effects of artemisinins; however, there are no studies that compare such effects between cancer cell lines and

Artemisinin disrupts androgen responsiveness of human prostate cancer cells by stimulating the 26S proteasome-mediated degradation of the androgen receptor protein.

Numai utilizatorii înregistrați pot traduce articole

Androgen receptor (AR) expression and activity is highly linked to the development and progression of prostate cancer and is a target of therapeutic strategies for this disease. We investigated whether the antimalarial drug artemisinin, which is a sesquiterpene lactone isolated from the sweet

Cirsilineol inhibits proliferation of cancer cells by inducing apoptosis via mitochondrial pathway.

Numai utilizatorii înregistrați pot traduce articole

Cirsilineol (4',5-dihydroxy-3',6,7-trimethoxyflavone) is a compound isolated from the herb of Artemisia vestita Wall (Compositae). In this study, we aimed at examining the anti-proliferative activity of cirsilineol against multiple types of cancer cells and the underlying mechanisms. Cirsilineol

The role of calcium, P38 MAPK in dihydroartemisinin-induced apoptosis of lung cancer PC-14 cells.

Numai utilizatorii înregistrați pot traduce articole

BACKGROUND Dihydroartemisinin (DHA), a semi-synthetic derivative of artemisinin isolated from the traditional Chinese herb Artemisia annua, is an effective novel antimalarial drug. Recent studies suggest that it also has anticancer effect. OBJECTIVE The present study was designed to investigate the

Inhibition of tumor cell proliferation and induction of apoptosis in human lung carcinoma 95-D cells by a new sesquiterpene from hairy root cultures of Artemisia annua.

Numai utilizatorii înregistrați pot traduce articole

Artemisia annua is a rich source of many bioactive substances, and in our recent work, a new sesquiterpene, (Z)-7-acetoxy-methyl-11-methyl-3-methylene-dodeca-1,6,10-triene (AMDT), was isolated and identified from hairy roots culture of A. annua, and its bioactivity was characterized in this work.

Artemisinin-transferrin conjugate retards growth of breast tumors in the rat.

Numai utilizatorii înregistrați pot traduce articole

BACKGROUND Artemisinin is a compound isolated from the wormwood Artemisia annua L. It reacts with iron and forms cytotoxic free radicals. It is selectively more toxic to cancer than normal cells because cancer cells contain significantly more intracellular free iron. Previously, we found that

Oral artemisinin prevents and delays the development of 7,12-dimethylbenz[a]anthracene (DMBA)-induced breast cancer in the rat.

Numai utilizatorii înregistrați pot traduce articole

Artemisinin, a compound isolated from the sweet wormwood Artemisia annua L., has previously been shown to have selective toxicity towards cancer cells in vitro. In the present experiment, we studied the potential of artemisinin to prevent breast cancer development in rats treated with a single oral
