Taxol Mechanism Of Action Pdf

DRUG NAME Paclitaxel BC Cancer. Paclitaxel (PTX), sold under the brand name Taxol among others, is a chemotherapy medication used to treat a number of types of cancer. This includes ovarian cancer , breast cancer , lung cancer , Kaposi sarcoma , cervical cancer , and pancreatic cancer . [2], Incubation of tubulin with taxol resulted in the assembly of tubulin in the absence of microtubule associated proteins. Optimum assembly occurred at approximately equal concentrations of tubulin and taxol. Both podophyllotoxin and colchicine inhibited the taxol-induced tubulin polymerization.

Paclitaxel, an antitumor drug that is demonstrating encouraging activity in human malignancies, is likely to play a major role in cancer chemotherapy. Paclitaxel has an unusual chemical structure Its novel mechanism of action provided the hope that it would demonstrate anti-neoplastic activity in multidrug resistant tumor cells. Unfortunately, as with other chemotherapeutic drugs, resistance is commonly seen. Laboratory investigation has defined a wide variety of resistance mechanisms including overexpression of multidrug resistance (MDR-1) gene, molecular changes in the target

Mechanism of Action Paclitaxel drug targets tubulin. Researchers have observed that Paclitaxel treated cells have difficulty with the spindle assembly, cell division and also chromosome segregation which is in opposing nature to Colchicine, a drug that targets tubulin. The major difference between Colchicine and Paclitaxel is that Colchicine inhibits the microtubule assembly whereas Paclitaxel If the inhibition of NHE1 is an integral part of the mechanism by which paclitaxel induces apoptosis, pharmacological inhibition of the NHE1 should potentiate paclitaxel action synergistically at low paclitaxel concentrations, and this potentiation should disappear as the paclitaxel concentration increases because its inhibition by paclitaxel reduces the possibility of additional inhibition by

How Paclitaxel Works News Medical. The mechanism of action of doxorubicin HCl, the active ingredient, is thought to be related to its ability to bind DNA and inhibit nucleic acid synthesis. Cell structure studies have demonstrated rapid cell penetration and perinuclear chromatin binding, rapid inhibition of mitotic activity and nucleic acid synthesis, and induction of mutagenesis and chromosomal aberrations, A proposed mechanism of action of trastuzumab is the reduction of the signalling from these pathways, thus promoting apoptosis and the arrest of proliferation . Diminished receptor signalling may result from trastuzumab-mediated internalisation and degradation of the HER2 receptor, but, as discussed above, it is unclear whether trastuzumab actually down-regulates HER2. An alternative mechanism.

    that the mechanism of the action of taxol involves the stabilization of microtubules (Schiff et al. 1979). Robert A. Holton and his group at Florida State University first succeeded in the total synthesis of taxol in 1994 (Holton et al. 1994a, b).
