Taxol, as a tetracyclic diterpene compound with anticancer activity, was firstly isolated from Taxus in 1971, and have been found it may help human against cancer by inhibiting the growth of cancer cell. In addition, Scientists have continuing to study its unique and profound properties for an anticancer agent.

Microtubules, polymers of tubulin that form part of the cytoskeleton and provide structure and shape to eukaryotic cells, are closely related to making up the mitotic spindle fibers necessary for M phase cell division. For rapidly dividing tumor cells, paclitaxel inhibits the mitotic spindle, thus stopping tumor cells in G1 and M stages until death.


Paclitaxel as an anticancer agent, it most widely used in anticancer drugs, and has been used for the treatment of various cancer including breast cancer, ovarian cancer, cervical cancer, lung cancer, and AIDS-related Kaposi sarcoma.
