  • Tesmilifene is a novel potentiator of chemotherapy which, when added to doxorubicin, achieved an unexpected and very large survival advantage over doxorubicin alone in a randomized trial in advanced breast cancer. (en)

http://linked.open...mechanismOfAction
  • Although the exact mechanism of action is not known, one study (PMID: 16413681) proposes that tesmilifene may be an activating p-gp substrate, which enables the p-gp pump to extrude typical p-gp substrates (such as anthracyclines or taxanes) more efficiently. This process consumes ATP, since the p-gp is absolutely, and highly dependent on ATP hydrolysis. The mechanism of cell death is likely to result not from the presence of chemotherapy inside the cell (in fact the chemotherapy is extruded) but, directly or indirectly, from the enhanced consumption of ATP. The ATP may be consumed below a threshold necessary for survival, or, (more likely) the enhanced ATP production required to maintain ATP levels may result in the generation of reactive oxygen species (ROS) to an extent that overwhelms the cell’s ability to inactivate them. The result would be additional cell death, but only in the mdr+ population. The doxorubicin would continue to act on the drug sensitive remainder of the cell population, but without the help of tesmilifene. (en)
