Product Description

Docetaxel, a semisynthetic analog of paclitaxel binds and stablizes tubulin, thus preventing microtubule disassembly, resulting in cell-cycle arrest at the G2/M phase and inducing apoptosis. Docetaxel is known to inhibit the anti-apoptotic gene Bcl2 and induces the expression of cell cycle inhibitor p27. (1)

In in vitro tubule formation assays, taxotere has an IC50 in the low nanomolar range. HUVEC migration assays were more sensitive, with IC50s in the picomolar range in a chemokinetic assay. Furthermore, HUVEC chemotaxis stimulated by either thymidine phosphorylase or vascular endothelial growth factor, was inhibited by Taxotere in the double-digit picomolar range. (2)

Docetaxel has been studied extensively in combination with traditional anti-cancer agents (e.g. gemcitabine) and more recently with newer generation agents such as cisplatin/5-fluorouracil (DCF), everolimus, sunitinib, and antibody therapies. (1, 3)
