Paclitaxel is a complex secondary metabolite extracted from the bark of Taxus taxus. It is also the only drug known to promote microtubule polymerization and stabilize polymerized microtubules. The isotope tracer showed that paclitaxel was only bound to the polymerized microtubules and did not react with the unpolymerized tubulin dimer. After contact with paclitaxel, cells will accumulate a large number of microtubules in the cell, and the accumulation of these microtubules interferes with various functions of the cell, especially the cell division stops in the mitosis period and blocks the normal division of the cell. Through Ⅱ-Ⅲ clinical studies, paclitaxel is mainly suitable for ovarian cancer and breast cancer, lung cancer, colorectal cancer, melanoma, head and neck cancer, lymphoma, brain tumor also have a certain effect. |

Paclitaxel powder is a chemotherapy drug that is given as a treatment for some types of cancer. Paclitaxel powder is a mitotic inhibitor now used to treat patients with lung, ovarian, breast cancer, head and neck cancer, and advanced forms of Kaposi's sarcoma. Paclitaxel is also used for the prevention of restenosis.
Function of Paclitaxel
1. Paclitaxel is a mitotic inhibitor drup used in the treatment of cancer.
2. Isolated the compound from the bark of the Pacific yew tree, Taxus brevifolia, and noted its antitumor activity in a broad range of rodent tumors.
3. Paclitaxel has since become an effective tool of doctors who treat patients with lung, ovarian, breast cancer, and advanced forms of Kaposi's sarcoma.
