vinca herbacea/breast neoplasms

Various active compounds (or their semi-synthetic derivatives) derived from medicinal plants have been assessed for their efficacy and tolerability in the treatment of breast cancer. Some of these plant species, including Taxus baccata (paclitaxel, docetaxel), Podophyllum peltatum (etoposide),

We treated 17 patients with metastatic breast cancer with the four-drug combination of vincristine (0.5-1.0 mg), vinblastine (4 mg/m2), doxorubicin (40 mg/m2), and cyclophosphamide (400 mg/m2). The two vinca alkaloids appeared to be synergistic in causing acute, reversible neurotoxicity, manifested

Vinca alkaloids are widely used in the medical treatment of breast cancer. Our study aimed to evaluate the therapeutic activity of a new vinca alkaloid derivative, S12363 (vinfosiltine), which is 36 and 72 times more cytotoxic in vitro than vincristine and vinblastine, respectively. Because phase I

BACKGROUND One of the main reasons for disease recurrence in the curative breast cancer treatment setting is the development of drug resistance. Microtubule targeted agents (MTAs) are among the most commonly used drugs for the treatment of breaset cancer and therefore overcoming taxane resistance is

Background - Treatment of cancer with natural chemotherapeutic agents induces apoptosis along with remarkable alterations in the expression of apoptosis-related genes. Deregulation of microRNA (miRNA) expression is implicated in several human malignancies. Vinca alkaloids compose a class of

The bisindole alkaloids vinblastine, vincristine, and N-formyl-leurosine were nitrated and subsequently converted to amino derivatives. In the case of compounds 5e and 5b cytotoxic activity has been found for non-small cell lung cancer and breast cancer in the concentration range tested

Antimicrotubule Vinca alkaloids, such as vinblastine and vincristine, interfere with the dynamics of microtubules and have shown significant cell killing activity in a variety of tumor cells through induction of apoptosis. The mechanism by which Vinca alkaloids induce apoptosis is not entirely

Vinorelbine (Navelbine) is a new, semisynthetic 5'Nor-vinca-alkaloid, modified on the catharantine ring, developed by Pierre Fabre Médicament. Vinorelbine is a potent as the other vinca alkaloids to inhibit mitotic microtubule polymerization. On the other hand, its activity is lower on axonal

Phase I study on a new vinca alkaloid derivative, KW-2307(vinorelbine), was conducted by multiple institutions in 40 patients with a variety of malignant tumors. KW-2307 was given intravenously by single administration or by weekly repeated for 4 weeks (hereinafter as the repeated administration).

The antitumour activity of the investigational agent vinblastine-isoleucinate (V-LEU) was compared with vintriptol, another investigational agent of the same series of vinblastine-23-oyl amino acid derivatives, and vinblastine, their clinically active parent compound, in a panel of nine human tumour

Vinca alkaloids (VAs) such as Vincristine, Vinblastine and Vinorelbine are antineoplastic drugs that inhibit tubulin polymerisation into microtubules, induce mitotic G2/M arrest, activate c-Jun N-terminal kinase (JNK) and induce apoptosis. Although there are many studies evaluating the effect of VAs

OBJECTIVE To review the pharmacology, pharmacokinetics, in vitro and in vivo efficacy, and safety profile of vinflunine in the treatment of various solid tumors. METHODS A literature search was conducted using keywords included vinflunine, vinca alkaloid, Javlor, and solid tumor in PubMed/MEDLINE

OBJECTIVE To review the drug profile and nursing implications of a new vinca alkaloid, vinorelbine tartrate (Navelbine, Burroughs Wellcome Co., Research Triangle Park, NC). METHODS Published articles, abstracts, professional communications, drug manufacturer, and personal experience with vinorelbine

1. Vinorelbine (NVB), a new semi-synthetic vinca alkaloid, is currently used in the treatment of advanced non-small-cell lung cancer (NSCLC) and advanced breast cancer. The pharmacokinetic profile of NVB has been redefined with a specific h.p.l.c. method which measures NVB and desacetyl-NVB. 2. In
