Biological Activity

Description Vincristine sulfate is an inhibitor of polymerization of microtubules by binding to tubulin with IC50 of 32 5M in a cell-free assay. Vincristine sulfate induces apoptosis.
Targets
Microtubules
(Cell-free assay)
32 μM
In vitro Vincristine sulfate inhibits net addition of tubulin dimers at assembly ends of steady-state microtubules with Ki of 85 nM. At low concentrations, this compound stabilises the spindle apparatus resulting in failure of the chromosomes to segregate leading to metaphase arrest and inhibition of mitosis. At higher concentrations, it may disrupt and induce total depolymerisation of microtubules. This chemical induces apoptosis in tumour cells and inhibits SH-SY5Y cell proliferation with IC50 of 0.1 5M. It induces mitotic arrest and promotes the expression of caspase-3 and -9 and cyclin B, while decreasing the expression of cyclin D. Its induced neurotoxicity is caused by interference with microtubule function, which results in blockage of axonal transport and thus in axonal degeneration.
In Vivo Vincristine sulfate (3 mg/kg) administered by a single i.p. injection to mice bearing bilateral subcutaneous xenografts Rh12 or Rh18, induces mean growth delay of >120 and >52 days, and repopulating fractions of 0.06% and 5%, respectively. This compound acts on subcutaneous colon 38 tumours in mice by host cell-mediated vascular effects as well as by direct tubulin-mediated cytotoxicity. It (5 mg/kg) reduces tumour blood flow of tumours by nearly 75%.

Protocol (from reference)

Cell Assay:[1]
  • Cell Lines

    B16 melanoma cell

  • Concentrations

    10 nM

  • Incubation Time

    3 days

  • Method

    Cells are plated in 2 mL of medium in 35-mm plates at a concentration of about 5 × 104 cells/mL and grow for 24 h at 37 ℃ in an atmosphere of 5% CO2 and 95% air. Then medium is replaced with fresh medium lacking or containing 4 nM drug and proliferation is continued for 3 days. Cell counts are done each day in a Coulter Counter after detaching the cells with trypsin and EDTA.
Animal Study:[6]
  • Animal Models

    Human rhabdomyosarcoma xenografts Rh12

  • Dosages

    3 mg/kg

  • Administration

    A single i.p. administration

Customer Product Validation

<p>for HXO-RB44 cells, IC50 values for VCR were changed in the different SG600 treatment groups. The results are representative of three independent  experiments and of f our replicates in each experiment.</p>

Plk inhibitor cooperates with chemotherapeutic agents. Conditional patched mutant tumor cells were treated with increasing concentrations of the chemotherapeutic agents vincristine alone or in combination with 10 nMol/L BI-2536. Cells were cultured for 48 hours, pulsed with 3H-Td, and harvested for analysis of 3H-Td incorporation at 66 hours.

Determination of mutation frequencies in cells treated with chemotherapy drugs following caspase inhibition. TK6 cells were incubated with no inhibitor or 10 μM QVD then treated with the following drug doses: 300 ng/ml TRAIL, 0.7 μM cisplatin, 0.5 μM temozolomide, 3 nM doxorubicin, 0.5 nM SN38 or 0.07 nM vincristine. (a) Caspase activity was assessed by luminescent detection of Caspase-3/-7 Glo reagent after 5 h. After 24- h treatment, (b) clonogenicity assays were performed to determine the proportion of cells maintaining clonogenic competency after treatment, whereas (c) surviving cells were grown in 6TG to select for the emergence of any HPRT mutants. (d) Clonogenicity and (e) HPRT mutation assays were repeated in CASP3/7 DKO lines in the same manner. Error bars represent mean±S.E.M. from at least three independent experiments. Two-sided T-tests were used to calculate P-values.

Discrimination of micronuclei induced by EMS and VCR in V79-hCYP2E1-hSULT1A1 cells as CENP-B negative or positive. The cells were treated with EMS (5 mM) or VCR (5 nM) for 6 h, followed by a recovery period of 18 h. They were stained for CENP-B (green) and β-tubulin (red) by the immunofluorescence assays, as described in Section 2.5. DNA was stained with DAPI (blue). The vertical and horizontal arrows indicate CENP-B-negative and CENP-B-positive micronuclei, respectively.
