A tetracyclic diterpenoid isolated originally from the bark of the Pacific yew tree, Taxus brevifolia. It is a mitotic inhibitor used in cancer chemotherapy. Note that the use of the former generic name 'taxol' is now limited, as Taxol is a registered trade mark.
Note: Use of the qualifier "multiple interactions" designates that the annotated interaction
is comprised of a complex set of reactions and/or regulatory events, possibly involving
additional chemicals and/or gene products.
