The NCI, established under the National Cancer Institute Act of 1937, is the Federal Government's principal agency for ...
A difluoromethylated ornithine compound with antineoplastic activity. Eflornithine irreversibly inhibits ornithine decarboxylase, an enzyme required for polyamine biosynthesis, thereby inhibiting the formation and proliferation of tumor cells. Polyamines are involved in nucleosome oligomerization and DNA conformation, creating a chromatin environment that stimulates neoplastic transformation of cells. This agent has been shown to induce apoptosis in leiomyoma cells.

A dietary supplement containing an extract powder derived from the root of the ashwagandha shrub with potential antineoplastic, antioxidant, immunostimulating and anti-angiogenic activities. Ashwagandha root powder extract contains numerous alkaloids, including withanine as the primary alkaloid, and steroidal lactone withanolides. The withanolides in this agent may suppress nuclear factor-kappaB activation and nuclear factor-kappaB-regulated gene expression, potentiating apoptosis and inhibiting tumor cell invasion. Cultivated in India and North America, ashwagandha (Withania somnifera Dunal or Indian ginseng) belongs to the Solanaceae (nightshade) family.

A dietary supplement containing extract from the medicinal fungus Antrodia cinnamomea with potential antiangiogenic, hepatoprotective and antioxidant activities. The components in Antrodia cinnamomea supplement are rather complex, however, rich in triterpenoids, polysaccharides, nucleosides (adenosine) nucleic acids, superoxide dismutase, other small molecular weight proteins and steroid like compounds. Neutral sugars in this supplement show inhibitory activity on endothelial tube formation, while maleimide and maleic anhydride derivative components in the extract, such as antrodin B and antrodin C and their metabolites, exhibit significant cytotoxic effects on tumor cells and hepatitis C virus.

A difluorocyclopropyl quinoline. Zosuquidar trihydrochloride binds with high affinity to P-glycoprotein and inhibits P-glycoprotein-mediated multidrug resistance (MDR). P-glycoprotein, encoded by the MDR-1 gene, is a member of the ATP-binding cassette superfamily of transmembrane transporters and prevents the intracellular accumulation of many natural product-derived cytotoxic agents.

A dietary supplement containing an extract of the Basidiomycete fungus Agaricus blazei Murill with potential chemopreventive, antineoplastic and immunopotentiating activities. Agaricus blazei Murill extract contains high levels of phytochemicals, especially beta-D-glucans. Beta-D-glucans may promote dendritic cell (DC) maturation; increase interferon gamma (IFN-gamma), tumor necrosis factor alpha (TNF-alpha) and immunoglobulin levels; and may enhance natural killer (NK) cell activity, potentially boosting anti-tumor host immune responses.
Industry:Pharmaceutical
A dietary supplement containing all or most of the vitamins that may not be readily available in the diet. Vitamins may be classified according to their solubility either in lipids (vitamins A, D, E, K, F) or in water (vitamins C, B-complex). Present in minute amounts in various foods, vitamins are essential to maintaining normal metabolism and biochemical functions.

A dietary supplement consisting of bovine colostrum, containing high titers of immunoglobulins (Igs), with immunostimulating and anti-infective activities. Hyperimmune bovine colostrum is harvested during the first days after calving from cows that have been inoculated repeatedly with specific pathogens during pregnancy. In addition to high titers of anti-pathogen specific antibodies, hyperimmune colostrum is also rich in other immune factors, proline-rich polypeptides (PRP), lactoferrin, glycoproteins, lactalbumins, cytokines, growth factors, vitamins, and minerals. This dietary supplement may exhbit anti-infective activity in immunocompromised patients.

A diarylsulfonylurea with potential antineoplastic activity. Sulofenur's antineoplastic mechanism of action is unknown.

A dietary supplement consisting of a mixture of strawberries, blackberries, black raspberries and blueberries with potential antineoplastic activity. Although the exact mechanism of action through which berries may exert their anti-tumor effect has yet to be elucidated, in vivo studies suggest that the ingestion of a mixture of berries seems to result in a reduction in tumor growth and tumor development. As berries are rich in phytonutrients, such as anthocyanins, flavonols, ellagitannins, galltannins, proanthocyanidins, and phenolic acids, the antineoplastic effects of strawberry-blackberry-black raspberry-blueberry berry mixture on cancer cells may be attributable to phytonutrient antioxidant and apoptotic activities. In addition, phytoestrogens in berries may be protective against estrogen-sensitive tumors.

A diagnostic radiopharmaceutical comprised of iodo-azomycin galactopyranoside (IAZGP) labeled with the positron-emitting radioisotope iodine I 124 and used as an imaging agent. Iodine I 124 iodo-azomycin galactopyranoside (I-124 IAZGP) is reduced under hypoxic conditions, covalently binding to macromolecules in hypoxic cells. After incorporation into hypoxic tumor cell DNA, I-124 IAZGP can be localized and quantified using positron emission tomography (PET), allowing a quantitative assessment of hypoxic tumor burden. IAZGP appears to have a higher water solubility and faster clearance from normal tissue than traditional imidazole tracers.
