Company Profile:
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 crosslinked nanoparticle formulation containing quaternary ammonium polyethylenimine (QA-PEI) with potential antibacterial activity. The cationic polymer PEI kills bacteria by rupturing their cell membranes without the development of resistance. Quaternary ammonium polyethylenimine nanoparticles can be incorporated into dental composite resins or silicon obturator prostheses and may prevent or delay bacterial growth.
Industry:Pharmaceutical
A cruciferous vegetable extract with potential chemopreventive activities. Broccoli sprout extract contains a high amount of sulforaphane, a naturally occurring isothiocyanate. Sulforaphane activates the transcription factor NF-E2-related factor 2 (Nrf2), a member of the basic leucine zipper family, which binds to and activates antioxidant-response elements (AREs). Subsequently, activated AREs mediate the transcription of antioxidant enzymes (particularly glutathione-S-transferase and quinone oxidoreductase), resulting in the detoxification of highly reactive carcinogens. AREs are cis-acting regulatory enhancer elements found in the 5’ flanking region of many phase II detoxification enzymes.
Industry:Pharmaceutical
A cream containing a non-ionic surfactant belonging to the polyethylene glycol (PEG) family. Polyethylene glycol 1000 cetyl ether is used as an ointment base, but can also be used as an emulsifier and solubilizer.
Industry:Pharmaceutical
A covalent conjugate of recombinant interferon alpha and polyethylene glycol (PEG), used as an antiviral and antineoplastic agent. The biological activity of this agent is derived from its interferon alpha protein moiety. Interferons alfa bind to specific cell-surface receptors, leading to the transcription and translation of genes whose protein products mediate antiviral, antiproliferative, anticancer, and immune-modulating effects. The PEG moiety lowers the clearance of interferon alpha, thereby extending the duration of its therapeutic effects, but may also reduce interferon-mediated stimulation of an immune response.
Industry:Pharmaceutical
A cream formulation containing aluminum chlorohydrate with astringent and antiperspirant activities. Upon topical application of F511 cream, aluminium chlorohydrate forms a gel matrix in the sweat gland which subsequently reduces, then stops the flow of water. In addition, this agent exerts an astringent effect, thereby further preventing sweat formation. Hyperhidrosis appears to play a role in the development of certain mucocutaneous reactions, such as palmar-plantar erythrodysesthesia (PPE), upon administration of chemotherapeutic agents such as doxorubicin, 5-fluorouracil, and capecitabine.
Industry:Pharmaceutical
A coordination complex consisting of a gadolinium ion bound to a hexadentate organic chelating agent such as diethylenetriaminepentaacetic acid. Chelates of gadolinium are frequently utilized as magnetic resonance imaging (MRI) contrast agents and can be used to track nanoparticle-mediated drug delivery.
Industry:Pharmaceutical
A copolymer conjugate of the antineoplastic anthracycline doxorubicin and the water-soluble polymer N-(2-hydroxypropyl) methacrylamide (HPMA). Doxorubicin, an intercalator and a topoisomerase II inhibitor, prevents DNA replication and ultimately inhibits protein synthesis. This agent also generates oxygen free radicals, resulting in cytotoxic lipid peroxidation of cell membrane lipid. HPMA conjugation enhances the permeability and retention of this agent within the tumor vasculature. Poorly cleared by the lymphatic system, this formulation undergoes increased cleavage by tumor cell lysosomal proteinases, resulting in increased, sustained intracellular concentrations of free doxorubicin. Compared to other doxorubicin-containing formulations, this formulation may exhibit an improved toxicity profile due to the lower concentrations of free doxorubicin to which non-malignant tissues are exposed.
Industry:Pharmaceutical
A conjugate consisting of keyhole-limpet hemocyanin (KLH) and fluorescein isothiocyanate (FITC) with potential immunostimulating activity. Vaccination with KLH-FITC may elicit an immune response against fluorescein and the production of anti-fluorescein IgG antibodies. KLH, a natural protein isolated from the marine mollusk keyhole limpet, is an immunostimulant carrier protein.
Industry:Pharmaceutical
A contrast agent containing an iodine-based dye used in many diagnostic imaging examinations, including computed tomography, angiography, and myelography.
Industry:Pharmaceutical
A controlled-release formulation of the 5-hydroxytryptamine 3 (5-HT3) antagonist granisetron, in which granisteron is encapsulated in a biodegradable poly(ortho ester) polymer, with antiemetic activity. Upon subcutaneous administration, APF530 slowly erodes and releases the active ingredient granisetron over a period of approximately 5 days. As a selective serotonin receptor antagonist, granisetron competitively blocks the action of serotonin at 5-HT3 receptors, resulting in the suppression of nausea and vomiting.
