The National Cancer Institute (NCI) is part of the National Institutes of Health (NIH), which is one of 11 agencies that compose the Department of Health and Human Services (HHS). The NCI, established under the National Cancer Institute Act of 1937, is the Federal Government's principal agency for ...
A biologically active, cysteine-rich, undenatured, bovine whey-based protein isolate with potential anti-cachexia and glutathione-enhancing properties. Upon administration of cysteine-rich whey protein isolate, cystine and glutamylcystine are taken up by cells and release free cysteine. The available cysteine allows cells to synthesize glutathione (GSH), a tripeptide made from amino acids glycine, glutamate and cysteine, thereby maintaining and increasing intracellular GSH concentrations. GSH plays a major role as an antioxidant, thereby protecting cells from oxidative damage due to harmful substances such as free radicals and reactive oxygen compounds. As IMN 1207 is rich in protein, this agent may prevent weight loss and increase body weight and strength.
Industry:Pharmaceutical
A bioadhesive gel containing 10% freeze-dried black raspberries (FBR) with potential chemopreventive and antioxidant activities. The four main constituent black raspberry anthocyanins that contribute significantly to the chemopreventive effects are cyanidin 3-glucoside (C3GLU), cyanidin 3-rutinoside (C3RUT), cyanidin 3-sambubioside (C3SAM) and cyanidin 3-(2(G)-xylosyl) rutinoside (C3XRUT). Upon mucosal application, the anthocyanins from the gel penetrate the oral mucosa and are able to modulate expression of certain proapoptotic and terminal differentiation genes, and reduce the expression of epithelial cyclooxygenase-2 (COX-2) protein. In addition, this gel may also reduce vascular densities in the superficial connective tissues.
Industry:Pharmaceutical
A biguanide compound used as an antiseptic agent with topical antibacterial activity. Chlorhexidine is positively charged and reacts with the negatively charged microbial cell surface, thereby destroying the integrity of the cell membrane. Subsequently, chlorhexidine penetrates into the cell and causes leakage of intracellular components leading to cell death. Since gram positive bacteria are more negatively charged, they are more sensitive to this agent.
Industry:Pharmaceutical
A bifunctional nitrogen alkylating agent with antineoplastic activity and lipophilic properties. Containing a lipophilic hydantoin group that serves as a carrier to cross the blood brain barrier, spiromustine forms covalent linkages with nucleophilic centers in DNA, causing depurination, base-pair miscoding, strand scission, and DNA-DNA cross-linking, which may result in cytotoxicity.
Industry:Pharmaceutical
A bifunctional hexitol derivative with potential antineoplastic activity. Dianhydrogalactitol alkylates and cross-links DNA via an epoxide group during all phases of the cell cycle, resulting in disruption of DNA function and cell cycle arrest.
Industry:Pharmaceutical
A bi-fluorinated derivative of the semi-synthetic vinca alkaloid vinorelbine with antitubulin, antineoplastic, and antiangiogenic activities. Vinflunine inhibits tubulin assembly without any stablization of assembled microtubules at concentrations comparable to those of other vinca alkaloids such as vincristine, vinblastine and vinorelbine; this effect on microtubule dynamics results in cell cycle arrest in mitosis and apoptosis. Compared to other vinca alkaloids, this agent binds weakly to the vinca-binding site, indicating that vinflunine may exhibit reduced neurotoxicity.
Industry:Pharmaceutical
A benzyl styryl sulfone analog, and a disodium phosphate ester prodrug of ON 013100, with potential antineoplastic activity. Upon hydrolysis, cyclin D modulator ON 013105 is converted to ON 013100, which blocks cyclin D mRNA translation and decreases protein expression of cyclin D. This may induce cell cycle arrest and apoptosis in cancer cells overexpressing cyclin D and eventually decrease tumor cell proliferation. This agent may exhibit synergistic antitumor activity in combination with other chemotherapeutic agents. Cyclin D, a member of the cyclin family of cell cycle regulators, plays a key role in cell cycle division and is often overexpressed in a variety of hematologic and solid tumors and is correlated with poor prognosis.
Industry:Pharmaceutical
A benzoyl-hydrazone derivative of the anthracycline antineoplastic antibiotic daunorubicin. Zorubicin intercalates into DNA and interacts with topoisomerase II, thereby inhibiting DNA replication and repair and RNA and protein synthesis.
Industry:Pharmaceutical
A benzopyran with potential antineoplastic activity. CC-8490 acts as a selective estrogen receptor modulator (SERM), inhibiting the proliferation of estrogen-sensitive breast cancer cells. This agent also inhibits growth and induces apoptosis of glioblastoma cells via a mechanism independent of estrogen receptor-related mechanisms.
Industry:Pharmaceutical
A benzofuran-based vascular disrupting agent (VDA) prodrug with potential anti-vascular and antineoplastic activities. Upon administration vascular disrupting agent BNC105P, the disodium phosphate ester of BNC105, is rapidly converted to BNC105; in activated endothelial cells, BNC105 binds to tubulin and inhibits its polymerization, which may result in a blockage of mitotic spindle formation, cell cycle arrest, and disruption of the tumor vasculature. Hypoxic conditions ensue, depriving tumor cells of nutrients and resulting in tumor cell apoptosis. In addition to its VDA activity, this agent has a direct cytotoxic effect on tumor cells by inhibiting tubulin polymerization. BNC105 is not a substrate for the multidrug-resistance P-glycoprotein (Pgp) transporter.
