Cabazitaxel is a semi-synthetic derivative of a natural taxoid that kills cancer cells by inhibiting cell division and growth. Cabazitaxel exerts its effects by inhibiting microtubule growth and assembly, processes that are essential for cells to divide.

ABCB1 functional inhibition using elacridar re-sensitizes TaxR and DU145-DTXR cells to cabazitaxel treatment. A. TaxR and DU145-DTXR cells were subjected to cell growth assays using either vehicle (DMSO), elacridar (0.5μM), cabazitaxel (1nM), or a combination of elacridar and cabazitaxel. Cells were counted 72 hours post-treatment. B. TaxR and DU145-DTXR cells were treated with either vehicle (DMSO), elacridar (0.5μM), cabazitaxel (1nM), or a combination of both elacridar and cabazitaxel for 72 hours. Whole cell lysates were then prepared and subjected to western blot analysis using indicated antibodies. Tubulin served as a loading control. c-PARP = cleaved-PARP, C = control (DMSO) treatment, Elac = elacridar, CTX = cabazitaxel. All data is presented as percent of control mean ± standard deviation. * = p-value ≤ 0.05.

|Description||Cabazitaxel is a semi-synthetic derivative of a natural taxoid that kills cancer cells by inhibiting cell division and growth. Cabazitaxel exerts its effects by inhibiting microtubule growth and assembly, processes that are essential for cells to divide.|
|Features||A semi-synthetic derivative of a natural taxoid.|
Cabazitaxel increases CYP3A enzyme activities in rat hepatocytes. The mean ex-vivo human plasma protein binding of Cabazitaxel is 91.6%. Cabazitaxel is rapidly and extensively metabolised in numerous metabolites. Cabazitaxel demonstrates activity in several murine and human resistant cell lines.  With a 4-day exposure to cabazitaxel, cytotoxicity is noted with relatively low cabazitaxel concentrations. Cabazitaxel shows high antitumor activity in 3 human colorectal cell lines (HCT-116, HCT-8, and HT-29). 
|In vivo||In accompanying models, Cabazitaxel is noted to have significant antitumor activity. In murine tumor xenografts (colon C38 and pancreas P03), Cabazitaxel elicites complete tumor regressions. Using SF-295 and U251 human glioblastoma cell lines, both orthotopic and subcutaneous murine xenografts are generated. Cabazitaxel treatment leads to complete regression in the majority of subcutaneously implanted tumors. Furthermore, in orthotopic models, Cabazitaxel leads to complete tumor regression in 4 out of 10 U251 tumors. |

* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.

Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (g) = Concentration (mol/L) × Volume (L) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
