10-Deacetyl Baccatin III (syn: 10-DAB) is a natural organic compound produced by the Pacific Yew tree.  It is used as a key backbone intermediate for the semi-synthesis of Paclitaxel (Taxol), an anti-cancer drug and Docetaxel and their analogs. It is used to study the biosynthetic pathway of Taxol.  The trunk and leaves contain the highest concentration of 10-Deacetyl Baccatin III, but it may be found in parts of the Yew tree.

    Mechanism of Action

    Paclitaxel (Taxol) has a unique mode of action involving abnormal polymerization of tubulin and disruption of mitosis.

    Storage Conditions

    2-8 °C

    Cancer Applications

    10-Deacetyl Baccatin III is commonly used as an intermediate in the synthesis of paclitaxel (Taxol), an anti-cancer drug.

    Plant Biology Applications

    Taxus cell culture may be an alternate source of Paclitaxel, and significantly increased amounts of Paclitaxel were observed after exposure to methyl jasmonate (Yukimune et al, 1996).
