Chemotherapy is a type of cancer treatment that uses one or more anti-cancer drugs as part of a standardized chemotherapy regimen. Chemotherapy may be given with a curative intent or it may aim to prolong life or to reduce symptoms. Chemotherapy is one of the major categories of the medical discipline specifically devoted to pharmacotherapy for cancer, which is called medical oncology.
Fluorouracil, sold under the brand name Adrucil among others, is a cytotoxic chemotherapy medication used to treat cancer. By intravenous injection it is used for treatment of colorectal cancer, oesophageal cancer, stomach cancer, pancreatic cancer, breast cancer, and cervical cancer. As a cream it is used for actinic keratosis, basal cell carcinoma, and skin warts.
Cisplatin is a chemical compound with formula cis-[Pt(NH3)2Cl2]. It is a coordination complex of platinum that is used as a chemotherapy medication used to treat a number of cancers. These include testicular cancer, ovarian cancer, cervical cancer, bladder cancer, head and neck cancer, esophageal cancer, lung cancer, mesothelioma, brain tumors and neuroblastoma. It is given by injection into a vein.
Epirubicin is an anthracycline drug used for chemotherapy. It can be used in combination with other medications to treat breast cancer in patients who have had surgery to remove the tumor. It is marketed by Pfizer under the trade name Ellence in the US and Pharmorubicin or Epirubicin Ebewe elsewhere.
Targeted therapy or molecularly targeted therapy is one of the major modalities of medical treatment (pharmacotherapy) for cancer, others being hormonal therapy and cytotoxic chemotherapy. As a form of molecular medicine, targeted therapy blocks the growth of cancer cells by interfering with specific targeted molecules needed for carcinogenesis and tumor growth, rather than by simply interfering with all rapidly dividing cells. Because most agents for targeted therapy are biopharmaceuticals, the term biologic therapy is sometimes synonymous with targeted therapy when used in the context of cancer therapy. However, the modalities can be combined; antibody-drug conjugates combine biologic and cytotoxic mechanisms into one targeted therapy.
Tirapazamine (SR-[[4233]]) is an experimental anticancer drug that is activated to a toxic radical only at very low levels of oxygen (hypoxia). Such levels are common in human solid tumors, a phenomenon known as tumor hypoxia. Thus, tirapazamine is activated to its toxic form preferentially in the hypoxic areas of solid tumors. Cells in these regions are resistant to killing by radiotherapy and most anticancer drugs. Thus the combination of tirapazamine with conventional anticancer treatments is particularly effective. As of 2006, tirapazamine is undergoing phase III testing in patients with head and neck cancer and gynecological cancer, and similar trials are being undertaken for other solid tumor types.
Crocetin is a natural apocarotenoid dicarboxylic acid that is found in the crocus flower together with its glycoside, crocin, and Gardenia jasminoides fruits. It is also known as crocetic acid. It forms brick red crystals with a melting point of 285 °C.
Estramustine phosphate (EMP), also known as estradiol normustine phosphate and sold under the brand names Emcyt and Estracyt, is a dual estrogen and chemotherapy medication which is used in the treatment of prostate cancer in men. It is taken multiple times a day by mouth or by injection into a vein.
Lapatinib (INN), used in the form of lapatinib ditosylate (USAN) is an orally active drug for breast cancer and other solid tumours. It is a dual tyrosine kinase inhibitor which interrupts the HER2/neu and epidermal growth factor receptor (EGFR) pathways. It is used in combination therapy for HER2-positive breast cancer. It is used for the treatment of patients with advanced or metastatic breast cancer whose tumors overexpress HER2 (ErbB2).
KRAS is a gene that provides instructions for making a protein called K-Ras, a part of the RAS/MAPK pathway. The protein relays signals from outside the cell to the cell's nucleus. These signals instruct the cell to grow and divide (proliferate) or to mature and take on specialized functions (differentiate). It is called KRAS because it was first identified as a viral oncogene in the KirstenRAt Sarcoma virus. The oncogene identified was derived from a cellular genome, so KRAS, when found in a cellular genome, is called a proto-oncogene.
Lonidamine is a derivative of indazole-3-carboxylic acid, which for a long time, has been known to inhibit aerobic glycolysis in cancer cells. It seems to enhance aerobic glycolysis in normal cells, but suppress glycolysis in cancer cells. This is most likely through the inhibition of the mitochondrially bound hexokinase. Later studies in Ehrlich ascites tumor cells showed that lonidamine inhibits both respiration and glycolysis leading to a decrease in cellular ATP.
Apatinib, also known as rivoceranib, is a tyrosine kinase inhibitor that selectively inhibits the vascular endothelial growth factor receptor-2. It is an orally bioavailable, small molecule agent which is thought to inhibit angiogenesis in cancer cells; specifically, apatinib inhibits VEGF-mediated endothelial cell migration and proliferation thus blocking new blood vessel formation in tumor tissue. This agent also mildly inhibits c-Kit and c-SRC tyrosine kinases.
Genta Incorporated was a biopharmaceutical company started in La Jolla, California, which discovered and developed innovative drugs for the treatment of patients with cancer. Founded in 1989 by a highly skilled entrepreneur, the company focused on a novel technology known as antisense, which targets gene products that are associated with the onset and progression of serious diseases. At that time, only Ionis Pharmaceuticals, Inc. was conducting significant research with this technology. Antisense is a short span of oligonucleotides – modified DNA structures ranging from about 12-24 bases that selectively bind to specific RNA. The intent is to block expression of an aberrant protein that contributes to the disease of interest. Genta in-licensed three different antisense molecules that blocked Bcl-2, a fibroblast growth factor (FGF), and the gene c-myb, respectively.
NAMI-A is the imidazolium]] salt of the coordination complex [RuCl4(dmso)(C3N2H4)]− where dmso is dimethylsulfoxide and C3N2H4 is imidazole Together with KP1019 and BOLD-100, NAMI-A has been investigated as an anticancer agent.
Nintedanib, sold under the brand names Ofev and Vargatef, is an oral medication used for the treatment of idiopathic pulmonary fibrosis and along with other medications for some types of non-small-cell lung cancer.
Brivanib alaninate (INN/USAN) also known as BMS-582664 is an investigational, anti-tumorigenic drug for oral administration. The drug is being developed by Bristol-Myers Squibb for the treatment of hepatocellular carcinoma or HCC, the most common type of liver cancer. Brivanib is no longer in active development.
Ruthenium anti-cancer drugs are coordination complexes of ruthenium complexes that have anticancer properties. They promise to provide alternatives to platinum-based drugs for anticancer therapy. No ruthenium anti-cancer drug has been commercialized.
Bernhard K. Keppler, born 1956 in Hockenheim, is a German bioinorganic chemist and physician. He is chair of inorganic chemistry at the University of Vienna, head of the Institute of Inorganic Chemistry and dean of the Faculty of Chemistry.
KP1019, or indazole trans-[tetrachlorobis(1H-indazole)ruthenate(III)], is one of four ruthenium anti-cancer drugs to enter into phase I clinical trials, the others being BOLD-100, NAMI-A and TLD-1433. Research into ruthenium-based drugs has provided novel alternatives for platinum-based chemotherapeutics such as Cisplatin and its derivatives. KP1019 is useful for metastatic tumors and cis-platin resistant tumors. It exhibits potent cytotoxicity against primary tumors, particularly in colorectal cancer.
G1 Therapeutics, Inc. is an American biopharmaceutical company headquartered in Research Triangle Park, North Carolina. The company specializes in developing and commercializing small molecule therapeutics for the treatment of patients with cancer.
