10-Deacetylbaccatins are a series of closely related natural organic compounds isolated from the yew tree (Genera Taxus). 10-Deacetylbaccatin III is a precursor to the anti-cancer drug docetaxel (Taxotere). 10-deacetylbaccatin III 10-O-acetyltransferase converts 10-deacetylbaccatin to baccatin III:
Isolating a natural product from its source can be costly in terms of time and materials, and may impact the availability of the natural resource or have ecological consequences. For example, it is estimated that harvesting enough paclitaxel for a single dose of therapy would require the bark of an entire yew tree (Taxus brevifolia). [124]
