Cabazitaxel, a Taxane for Men With Hormone-Refractory Metastatic Prostate Cancer
October 19th 2010Cabazitaxel is a microtubule inhibitor in the taxane class. It is made from a yew needle precursor using a semisynthetic process. It binds to free tubulin, which is used during mitosis to form two daughter cells.
Bevacizumab for Renal Cell Carcinoma,Glioblastoma, and Other Solid Tumors
October 9th 2009In July 2009, the US Food and Drug Administration (FDA) granted approval for use of the vascular endothelial growth factor (VEGF) inhibitor bevacizumab (Avastin) in combination with interferon alfa for treatment of patients with metastatic renal cell carcinoma (RCC).
An Alkylating Agent for CLL and NHL
April 9th 2009Bendamustine HCl for injection is FDA approved for treatment of patients with chronic lymphocytic leukemia (CLL) or indolent B-cell non-Hodgkin’s lymphoma (NHL) that has progressed during or within 6 months of treatment with rituximab (Rituxan) or a rituximab-containing regimen.
The Cytochrome P450 Microenzyme System and Targeted Therapies
February 25th 2009The cytochrome P450 microenzyme system has been an important protective system for living things for at least 3 billion years. It is a group or superfamily of isoenzymes that live in the endoplasmic reticulum and mitochondrial membrane of cells, and initially were responsible for detoxifying any poisons that were inhaled or ingested. As a result, these enzymes are found in the nose, saliva, kidneys, and lungs, and in greater numbers in the small intestines and liver. Cytochrome P450s account for about 75% of total metabolism and are important in oxidative metabolism-chemical modification/degradation of drugs.
Small Molecule Multitargeted TKI Therapy
October 1st 2008Sorafenib is indicated for the treatment of patients with advanced renal cell cancer, and patients with unresectable hepatocellular cancer. Sunitinib is indicated for the treatment of patients with advanced renal cell cancer, and patients with gastrointestinal stromal tumor (GIST) after disease progression on imatinib mesylate (Gleevec).
Drug Essentials Levoleucovorin, a Cytoprotectant
July 1st 2008Drug is indicated for rescue of normal cells following high dose methotrexate administration for osteosarcoma. It is also indicated to diminish and counteract methotrexate toxicity if the drug is not effectively eliminated, or for inadvertent overdose of folic acid antagonists.
mTOR* Inhibitors *mammalian target of rapamycin
April 2nd 2008Drug is a kinase inhibitor that blocks the action of mTOR (mammalian target of rapamycin). mTOR plays an important role in regulating key cellular functions, such as cell proliferation, survival, movement, and angiogenesis. It is part of the P13K (phosphoinositide 3-kinase)/Akt (protein kinase) signaling pathway which is often mutated in cancer. When mTOR is blocked, this leads to cell cycle arrest in the G1 phase of the cell cycle.
