How was Taxol discovered?

Taxol belongs to a class of chemotherapy drugs called plant alkaloids. Plant alkaloids are made from plants. The vinca alkaloids are made from the periwinkle plant (catharanthus rosea). The taxanes are made from the bark of the Pacific Yew tree (taxus). The vinca alkaloids and taxanes are also known as antimicrotubule agents. The podophyllotoxins are derived from the May Apple plant. Camptothecan analogs are derived from the Asian "Happy Tree" (Camptotheca acuminata). Podophyllotoxins and camptothecan analogs are also known as topoisomerase inhibitors. The plant alkaloids are cell-cycle specific. This means they attack the cells during various phases of division. * Vinca alkaloids: Vincristine, Vinblastine and Vinorelbine. * Taxanes: Taxol and Docetaxel. * Podophyllotoxins: Etoposide and Tenisopide. * Camptothecan analogs: Irinotecan and Topotecan. Antimicrotubule agents (such as Taxol), inhibit the microtubule structures within the cell. Microtubules are part of the cell's apparatus for dividing and replicating itself. Inhibition of these structures ultimately results in cell death. I hope this helps Please understand that drugs are "discovered" every minute and go through many levels of testing and departments of our great "laws for processes" in order to be introduced to the medical world. It is possible that the drug companies will not release any further information then the above facts in order to protect the creative employee or other persons involved in its creation.


How do you get ovarian cancer?

Ovarian cancer is caused by cells of the ovaries not doing the "job" they are supposed to do, and instead revert all of their energy into uncontrolled reproduction. This is true of all cancers. The reason it is so hard for the body to fight off cancer is because it is actually the body's own cells that cause the problem. When cells grow at an uncontrolled rate, it becomes difficult for the other healthy cells to perform their function due to the fact they become outnumbered by the cancerous cells. Eventually these cancerous cells can enter the blood stream or lymph system and spread to other organs. Cancer usually causes a patient's demise due to the fact it causes organs to shut down, because all the energy is spent on uncontrolled cell growth, rather than cell function.
