Product Description

Vinblastine (formerly NSC49842; NSC-49842; NSC 49842; Velban; Velsar; VLB; Vincaleukoblastine), a naturally occuring alkaloid isolated from the plant Vinca rosea Linn, is an approved anticancer drug acting as a potent mitotic inhibitor that inhibits microtubule assembly/formation. It has been approved for use in the treatment of various cancers. Vinblastine acts by binding to tubulin and inhibiting the formation of microtubule, thus leading to the disruption of mitotic spindle assembly and arrest of tumor cells in the G2/M phase of the cell cycle.

Biological Activity I Assay Protocols (From Reference)

ln Vitro

In vitro activity: The average terminal half-lives of Vinblastine is 14.3 h. When incubated in freshly isolated rat hepatocytes, VLB penetrates rapidly and intensely into the cells, probably through a passive diffusion mechanism followed by tight cellular binding. Vinblastine inhibits the angiogenic response induced by adrenomedullin and is also positive for mitotic slippage, causing micronuclei in mononucleate cells with cytokinesis block. vinblastine gives significant increase in micronucleated mononucleated cells at concentrations that produced approximately 50% cell death and cytostasis or less as calculated using RPD, RICC and RCC.

Cell Assay: Six-well treatment plates are set up that contained 5 × 104 cells/mL (Chinese hamster ovary (CHO) cells) in each well, suspended in 3 mL culture medium, and these are treated with vinblastine for 3 h followed by 21 h growth.

ln Vivo

Vinblastine is a widely used anticancer drug with undesired side effects. A combination of VBL and RAP at very low doses against human HCC gets a satisfactory antiangiogenic effect in vivo. The clinically relevant dose of vinblastine inhibits palmitoylation of tubulin in vivo in CEM cells (effect on depalmitoylation of tubulin).

Solubility Data

Solubility (In Vitro)

DMSO:100 mg/mL (110.0 mM)

Water:<1 mg/mL

Ethanol:<1 mg/mL

Preparing Stock Solutions		1 mg	5 mg	10 mg
	1 mM	1.2331 mL	6.1655 mL	12.3309 mL
	5 mM	0.2466 mL	1.2331 mL	2.4662 mL
	10 mM	0.1233 mL	0.6165 mL	1.2331 mL

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.

Molarity Calculator allows you to calculate the mass, volume, and/or concentration required for a solution, as detailed below:

Calculate the Mass of a compound required to prepare a solution of known volume and concentration
Calculate the Volume of solution required to dissolve a compound of known mass to a desired concentration
Calculate the Concentration of a solution resulting from a known mass of compound in a specific volume

See Example

An example of molarity calculation using the molarity calculator is shown below:
What is the mass of compound required to make a 10 mM stock solution in 5 ml of DMSO given that the molecular weight of the compound is 350.26 g/mol?

Enter 350.26 in the Molecular Weight (MW) box
Enter 10 in the Concentration box and choose the correct unit (mM)
Enter 5 in the Volume box and choose the correct unit (mL)
Click the “Calculate” button
The answer of 17.513 mg appears in the Mass box. In a similar way, you may calculate the volume and concentration.

Dilution Calculator allows you to calculate how to dilute a stock solution of known concentrations. For example, you may Enter C1, C2 & V2 to calculate V1, as detailed below:

What volume of a given 10 mM stock solution is required to make 25 ml of a 25 μM solution?
Using the equation C1V1 = C2V2, where C1=10 mM, C2=25 μM, V2=25 ml and V1 is the unknown:

Enter 10 into the Concentration (Start) box and choose the correct unit (mM)
Enter 25 into the Concentration (End) box and select the correct unit (mM)
Enter 25 into the Volume (End) box and choose the correct unit (mL)
Click the “Calculate” button
The answer of 62.5 μL (0.1 ml) appears in the Volume (Start) box
