生物活性：

Antitumor agent; promotes and stabilizes tubulin polymerization, causing cell cycle arrest. Induces autocatalytic activation of caspase-10 in CCRF-HSB-2cells, triggering apoptosis.

It selectively inhibits the proliferation of human endothelial cells (ECs) at ultra low concentrations (0.1-100 pM), while it inhibits non-endothelial type human cells at 10(4) - to 10(5) -fold higher concentrations, with IC50 = 1-10 nM. The selectivity of paclitaxel inhibition of cell proliferation is also species specific, as mouse ECs are not sensitive to paclitaxel at ultra low concentrations. They are inhibited by higher concentrations of paclitaxel with IC50 = 1-10 nM. Inhibition of human ECs by paclitaxel at ultra low concentrations does not affect the cellular microtubule structure. Paclitaxel blocks cells in G2-M, and this may result in a schedule-dependent effect on paclitaxel cytotoxicity.
