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 nitric oxide (NO) donating derivative of acetylsalicyclic acid with anti-inflammatory, analgesic, antipyretic, antithrombotic, gastroprotective and potential antitumor activities. The acetylsalicylic acid derivative moiety of this agent inhibits the activities of cyclooxygenase (COX) I and II, preventing the formation of prostaglandins and thromboxanes. A reduction in prostaglandin synthesis accounts for this agent's anti-inflammatory, anti-pyretic and analgesic activities; a reduction in thromboxane A2 synthesis results in an irreversible inhibition of platelet aggregation. NO donation by this agent, after cleavage from the acetylsalicylic acid derivative in vivo, may protect the gastric mucosa against the damaging effects of the aspirin derivative by modulating prostaglandins. In tumor cells, the NO donating moiety may block the cell cycle in the G1 and G2 phases and may induce apoptosis through caspase-mediated mechanisms.

A nine amino acid peptide fragment of carcinoembryonic antigen (CEA), a protein that is overexpressed in several cancer cell types, including gastrointestinal, breast, and non-small cell lung. Autologous vaccination with activated autologous dendritic cells (DC) or peripheral blood mononuclear cells (PBMC) which have been exposed to CEA peptide 1 in vitro may stimulate the host immune system to mount a cytotoxic T lymphocyte (CTL) response against tumor cells expressing CEA, thereby inhibiting tumor growth.
Industry:Pharmaceutical
A new generation organic platinum analog with an extended spectrum of antineoplastic activity. Designed to overcome platinum drug resistance, picoplatin alkylates DNA, forming both inter- and intra-strand cross-linkages, resulting in inhibition of DNA replication and transcription, and the induction of apoptosis.
Industry:Pharmaceutical
A neuroattenuated, replication-restricted, ICP34. 5 deleted (RL1 gene)-mutant herpes simplex virus (HSV) type I, constructed from wild-type strain 17, with potential oncolytic activity. Upon intratumoral injection, oncolytic HSV1716 transfects, replicates in, and lyses rapidly dividing cells such as tumor cells. Because the RL1 gene is deleted , HSV1716 is unable to replicate in non-dividing cells.

A neuroattenuated, replication-competent, recombinant herpes simplex virus-1 (HSV-1) with potential oncolytic activity. Upon intracerebral administration, oncolytic HSV-1 G207 preferentially replicates within glioma cells, which may elicit tumor-specific systemic immune and cytotoxic T lymphocyte (CTL) responses in addition to direct cytopathic effects. Derived from wild-type HSV-1 strain F, this agent has been neuroattenuated by deletions in both copies of the gamma34. 5 gene, the major determinant of HSV neurovirulence. In addition, the HSV-1 gene UL39, encoding the viral ribonucleotide reductase large subunit infected cell protein 6 (ICP6), has been inactivated through the insertion of the Escherichia coli lacZ gene. By inactivating UL39, viral ribonucleotide reductase activity is disrupted, resulting in the inhibition of nucleotide metabolism and viral DNA synthesis in nondividing cells but not in dividing cells.

A naturally-occurring salinosporamide, isolated from the marine actinomycete Salinospora tropica, with potential antineoplastic activity. Marizomib irreversibly binds to and inhibits the 20S catalytic core subunit of the proteasome by covalently modifying its active site threonine residues; inhibition of ubiquitin-proteasome mediated proteolysis results in an accumulation of poly-ubiquitinated proteins, which may result in the disruption of cellular processes, cell cycle arrest, the induction of apoptosis, and the inhibition of tumor growth and angiogenesis. This agent more may more potent and selective than the proteasome inhibitor bortezomib.
Industry:Pharmaceutical
A naturally-occurring phytochemical belonging to the class of isothiocyanates. As the aglycone metabolite of glucosinolate glucoraphanin (sulforaphane glucosinolate), sulforaphane acts as an antioxidant and potent stimulator of endogenous detoxifying enzymes. This agent displays anticarcinogenic properties due to its ability to induce phase II detoxification enzymes, such as glutathione S-transferase and quinone reductase, thereby providing protection against certain carcinogens and toxic, reactive oxygen species. Broccoli sprouts contain large amounts of sulforaphane, which is also found in other cruciferous vegetables including cabbage and kale.
Industry:Pharmaceutical
A naturally-occurring human IgM monoclonal antibody with potential antineoplastic activity. Human monoclonal antibody 216, derived from the gene VH4-34, binds to the glycosylated epitope CDIM on the surface of both malignant and normal B cells. Upon binding to B cells, this antibody may crosslink two or more CDIM molecules, resulting in the formation of cell membrane pores, the disruption of cell membrane integrity, and B cell lysis; this mechanism of antibody-mediated cell death is direct and does not involve mechanisms of complement-mediated cytotoxicity or antibody-depndent cell-mediated cytotoxicity (ADCC). CDIM is the glyco-moiety of a 75 kD MW B-cell cell surface glycoprotein.
Industry:Pharmaceutical
A naturally-occurring fatty acid ester form of retinol (vitamin A) with potential antineoplastic and chemopreventive activities. Retinyl acetate binds to and activates retinoid receptors, inducing cell differentiation and decreasing cell proliferation. This agent also inhibits carcinogen-induced neoplastic transformation in some cancer cell types and exhibits immunomodulatory properties.
Industry:Pharmaceutical
A naturally occurring, orally available cleavage product of the glucosinolate glucobrassicanin, a natural compound present in a wide variety of plant food substances including members of the family Cruciferae with antioxidant and potential chemopreventive properties. Indole-3-carbinol scavenges free radicals and induces various hepatic cytochrome P450 monooxygenases. Specifically, this agent induces the hepatic monooxygenase cytochrome P4501A1 (CYP1A1), resulting in increased 2-hydroxylation of estrogens and increased production of the chemoprotective estrogen 2-hydroxyestrone.
