Vinorelbine (VNR) is a new semi-synthetic Vinca rosea alkaloid that has been employed both in combination and as a single agent, showing a significant antitumour activity. Since little is known about VNR in human leukemia, we studied the in vitro cytotoxic effect of VNR on peripheral blood

Vinorelbine (VNR) is a semi-synthetic Vinca rosea alkaloid that has been employed both as a single agent and in combination, and has shown significant antitumor activity. As little is known about VNR activity on human leukemia, we studied its in vitro cytotoxic effect on human leukemia cell lines

Forty-one consecutive adult patients with acute myeloid leukemia (AML) were treated with an intensive individualized induction therapy of behenoyl cytarabine, daunorubicin, and 6-mercaptopurine, 29 patients (71%) achieved complete remission (CR). Patients then received three courses of intensive

Vinca alkaloids are used extensively in the treatment of childhood acute lymphoblastic leukemia (ALL) and despite their usefulness, drug resistance remains a serious clinical problem. Vinca alkaloids bind to the beta-tubulin subunit of the alpha/beta-tubulin heterodimer and inhibit polymerization of

Twelve monomeric or dimeric alkaloids from Vinca rosea Linn., which had been reported to have little or no antitumor activity, were investigated to determine their combined effects with either vincristine or daunorubicin on in vitro cell growth of a P388 subline resistant to vincristine and

Uptake and retention of vincristine (VCR), vinblastine (VB), and vindesine (VD) in isolated mononuclear cells from six healthy donors and in leukemic cells from 12 patients with chronic lymphatic leukemia (CLL) were studied: Three patients responded to VCR-containing regimens, whereas 4 patients

The cytotoxic, antimitotic, and growth inhibition properties of a photoactive analogue of vinblastine, N-(p-azidobenzoyl)-N'-beta-aminoethylvindesine (NABV), and vinblastine on P388 murine leukemia cells were compared. After 72-h exposure, the 50% drug-inhibitory concentrations for exponentially

Vinca alkaloids are used widely in the treatment of both childhood and adult cancers. Their cellular target is the beta-tubulin subunit of alpha/beta-tubulin heterodimers, and they act to inhibit cell division by disrupting microtubule dynamics. Despite the effectiveness of these agents, drug

On-patent and off-patent drugs with previously unrecognized anticancer activity could be rapidly repurposed for this new indication given their prior toxicity testing. To identify such compounds, we conducted chemical screens and identified the antihelmintic flubendazole. Flubendazole induced cell

Near diploid leukemic T-cells (LALW-2), exposed to cytotoxic drugs only as a consequence of therapy administered to the donor patient, have been maintained by serial xenograft in nude mice. In comparison with the leukemic line CCRF-CEM, using a growth inhibition assay, LALW-2 cells were resistant to
