Mechanism of Action

Features	A semi-synthetic derivative of a natural taxoid.
Targets/IC₅₀/Ki	Microtubule (Cell-free assay)
In vitro	Cabazitaxel increases CYP3A enzyme activities in rat hepatocytes. The mean ex-vivo human plasma protein binding of this compound is 91.6%. It is rapidly and extensively metabolised in numerous metabolites. This compound demonstrates activity in several murine and human resistant cell lines. With a 4-day exposure to this chemical, cytotoxicity is noted with relatively low cabazitaxel concentrations. It 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), this compound elicites complete tumor regressions. Using SF-295 and U251 human glioblastoma cell lines, both orthotopic and subcutaneous murine xenografts are generated. This chemical treatment leads to complete regression in the majority of subcutaneously implanted tumors. Furthermore, in orthotopic models, it leads to complete tumor regression in 4 out of 10 U251 tumors.
