Description
Baccatin III is a natural product isolated from Pacific yew tree and related species. Baccatin III reduces tumor progression by inhibiting the accumulation and suppressive function of MDSCs[1].
Baccatin III is a tetracyclic diterpenoid isolated from plant species of the genus Taxus. It has a role as a plant metabolite. It is a tetracyclic diterpenoid, an acetate ester and a benzoate ester. It derives from a hydride of a taxane.|Baccatin III is a compound obtained from the needles of the Taxus baccata tree that is used as a precursor of paclitaxel.
