Breast cancer is the most common malignancy in women, accounting for about 18% of female cancers, and over half a million new cases are diagnosed worldwide each year. Its incidence increases with age and is currently rising. Although the increased availability of screening programs has allowed
Paclitaxel, a chemotherapeutic drug isolated from the Pacific yew, was approved for the treatment of metastatic breast cancer in 1994 and remains one of the most important agents in the treatment of patients with this disease. It is currently approved for the adjuvant treatment of node-positive
Paclitaxel (TAXOL), a novel diterpene plant product isolated from the western yew Taxus brevifolia, is an active agent in the treatment of lung cancer. In two studies, the drug produced 21% and 24% objective response rates among patients with non-small cell lung cancer. A response rate of 34% was
Taxanes, derived from the bark of the Pacific yew tree, were the last major group of cytotoxic agents to be developed. Their proven efficacy in a variety of malignancies has constituted a real breakthrough in the treatment of cancer. Wider clinical use of taxanes has several important limitations,
BACKGROUND
Paclitaxel, a natural product from Taxus brevifolia, is a microtubule stabilizing agent, which has been shown to block different cells in the G2/M phase of the cell cycle and consequently, to modulate their radioresponsiveness. Our aim was to test the cytotoxic and radiosensitizing
Taxol is a cytostatic agent of plant origin with a complex structure and a special mode of action. Owing to the small content of this substance in the bark of the Pacific yew, from which Taxol is derived, it has only been available on a limited scale. Hitherto, Taxol's chemical structure has
Paclitaxel, which isolated from Taxus brevifolia, is recently started to be used against prostate cancer treatment and it is a very effective compound against cancer. In this study, we aimed to test the synergistic effect of two plant active compounds (sulphoraphane (SFN) and silymarin (SILY)) and
Herbs have been considered natural and valuable sources for anticancer drug discovery. Herbal medicine has been prescribed in many countries over centuries for treating various diseases including infectious and malignant diseases. Nowadays, many of the drugs that have been used for treatment of
Paclitaxel and docetaxel are antineoplastic drugs derived from the yew tree, Taxus brevifolia. They are the members of the taxane family and act by inhibiting mitotic activity due to the suppression of microtubule depolymerization. They are used in the treatment of ovarian cancer, breast cancer,
Taxol, an antineoplastic agent isolated from the Pacific yew, has been demonstrated in three phase 2 clinical trials to have major activity (30 percent overall response rate) in patients with ovarian cancer refractory to cisplatin. The major toxicities associated with the agent are neutropenia
Taxol is a powerful and complex anti-cancer compound that was first isolated from the bark of the Pacific yew Taxus brevifolia. Although it offered huge potential as an anti-cancer agent, it experienced a long development period, attributed to by its low availability from its traditional source.
Paclitaxel (Taxol) is a diterpine plant compound that was isolated initially from the bark of the western yew tree, Taxus brevifolia, but can now be produced by semisynthesis from a renewable source. Paclitaxel is the first new agent in the past decade to have confirmed single agent activity in
Background - L-Dopa decarboxylase (DDC) expression has been implicated in the biochemistry of several human cancers. Docetaxel and Mitoxantrone are two widely used anticancer agents. Docetaxel is a semi-synthetic analogue of paclitaxel, an extract from the bark of the rare Pacific yew tree Taxus
Paclitaxel (Taxol) is an intravenously administered antineoplastic agent derived from the yew tree, Taxus brevifolia, whose mechanism of action involves inhibition of mitosis. Some of the mucocutaneous reactions to the drug that have been observed include alopecia, mucositis, hypersensitivity
The chemistry, pharmacology, pharmacokinetics, clinical efficacy, adverse effects, and dosage of paclitaxel are reviewed. Paclitaxel is a diterpenoid taxane derivative found in the bark and needles of the western yew, Taxus brevifolia. Although it shares some structural similarities with other
