These medicines are active in the M-Phase.  In the nucleus of the dividing cell they bind to the microtubules and stop reproduction.  Scientists call these cytoskeletal disruptors or microtubule-targeting agents.  The name taxane comes from taxus, which is a genus of tree (the yew trees).  Three taxanes are approved in the US for cancer treatment.

In addition to taxanes, other natural substances used in chemotherapy include trabectedin and the vinca alkaloids.
