taxus baccata/化學療法

BACKGROUND Docetaxel, a semisynthetic analog of paclitaxel, made for the needles of the European yew, Taxus baccata, is a potentially important chemotherapeutic agent for the treatment of cancer. METHODS In a phase II study patients with advanced and/or metastatic breast cancer and bidimensionally

Docetaxel (Taxotere) is a taxoid derived from the European yew tree, taxus baccata. In 4 phase-II studies docetaxel has important single agent activity with an overall prostate-specific antigen response rate of 42% in hormone refractory prostate cancer. Other phase-II studies suggest that the

Ovarian cancer is most frequently diagnosed at an advanced stage. In recent years there has been intense interest in the chemotherapy of this disease. About cisplatin, the most active agent in the treatment of advanced ovarian cancer, some questions are only partially answered, as the optimal dose,

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

A late phase II clinical trial of RP56976 (docetaxel), derived from Taxus baccata was performed to evaluate anti-tumour activity, time to progression and clinical toxicity in patients with advanced or recurrent breast cancer. The patients, between 15 and 80 years old with performance status (PS) of

N-Debenzoyl-N-tert-butoxycarbonyl-10-deacytyl taxol (Taxotere, RP 56976) is a semisynthetic analogue of taxol, prepared from a noncytotoxic precursor extracted from the needles of the European yew tree (Taxus baccata L.). It has a broad spectrum of antitumor activity against a variety of

Progress in cancer chemotherapy has been made owing to the discovery and development of drugs that have new structures, new mechanisms of action, and high levels of experimental antitumor activity. Docetaxel (Taxotere; Rhône-Poulenc Rorer, Antony, France) is prepared by semisynthesis from

Docetaxel is a new semi-synthetic anticancer agent derived from bacatin III of the needles of the European yew Taxus baccata. Docetaxel has a novel mechanism of action since it binds to tubulin inducing its polymerization and promoting stable microtubule formation. Several differences exist between

Docetaxel (Taxotere; Rhône-Poulenc Rorer, Antony, France) is a hemisynthetic derivative from European yew that inhibits tubulin depolymerization and enhances the formation of microtubule bundle aggregates, causing cell death. Activity against a variety of tumor types has been reported. Single-agent

Therapy for advanced breast cancer has not improved significantly in recent years, remaining strictly palliative in nature and intent. One approach to increase the effectiveness of the treatment is the introduction of active new drugs. Taxotere (docetaxel) is a taxoid derivative isolated from the

BACKGROUND Docetaxel (Taxotere) is prepared from a noncytotoxic precursor extracted from the needles of the Taxus baccata. Preclinical investigations have demonstrated that docetaxel is very active in colon adenocarcinoma murine models. Phase I studies revealed granulocytopenia to be the

The objective of this paper is to review the data supporting the use of docetaxel in the treatment of breast cancer, focusing on pharmacokinetics, efficacy in adjuvant and metastatic trials alone and in combination with chemotherapeutic and targeted agents, and the toxicity of docetaxel in

Taxol, a phyto-extracted diterpenoid, is the most commercially needed drug in cancer chemotherapy. In spite of the microbial production of taxol being successful and prospective, the reported yields are still not sufficient for large-scale production. Thus, the discovery of new taxol-producing

The taxanes (paclitaxel and docetaxel) represent an important class of antineoplastic agents that interfere with microtubule function leading to altered mitosis and cellular death. Paclitaxel (Taxol(®)) was originally extracted from a yew tree (Taxus spp., Taxaceae) a small slow-growing evergreen,
