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 modified recombinant nonapeptide (LMLGEFLKL) derived from the anti-apoptosis protein survivin with potential immunopotentiating and antineoplastic activities. Upon administration, survivin Sur1M2 peptide vaccine may elicit humoral and cellular immune responses against survivin-expressing cancers, resulting in decreased tumor cell proliferation and tumor cell death. The survivin protein inhibits caspase activation and apoptosis; it is undetectable in normal adult tissues but is expressed by several human cancers including lung, colon, breast, pancreas, and prostate cancer as well as hematopoietic malignancies and skin cancers.

A modified amino acid and structural analog of glutamine. Acivicin inhibits glutamine amidotransferases in the purine and pyrimidine biosynthetic pathways, thereby inhibiting tumor growth in cell lines dependent on glutamine metabolism.
Industry:Pharmaceutical
A mixture of two recombinant IgG1 antibodies directed against different epitopes in the epidermal growth factor receptor (EGFR) extracellular domain III, with potential antineoplastic activity. Anti-EGFR monoclonal antibody mixture Sym004 binds to the extracellular domain of EGFR, thereby preventing ligand binding. This may prevent activation and subsequent dimerization of the receptor; the decrease in receptor activation may result in an inhibition of downstream ERK and JNK signaling pathways and thus inhibition of EGFR-dependent tumor cell proliferation and metastasis. In addition, binding of Sym004 to EGFRs causes EGFR internalization and degradation. EGFR, a receptor tyrosine kinase, often is overexpressed on the cell surfaces of various solid tumor cell types.
Industry:Pharmaceutical
A mixture of highly sulfated, monophosphorylated mannose oligosaccharides, derived from the extracellular phosphomannan of the yeast Pichia (Hansenula) holstii, with potential antiangiogenic activity. Heparanase inhibitor PI-88 inhibits the endo-beta-D-glucuronidase heparanase, which may interfere with the heparanase-mediated degradation of heparan-sulfate proteoglycans in extracellular matrices, an important step in the metastatic process. This agent may also bind with high affinity to the heparan sulfate-binding domains of vascular endothelial growth factor (VEGF) and fibroblast growth factors 1 and 2, thereby reducing their functional activities and inhibiting VEGF and FGF stimulation of tumor angiogenesis. Increased heparanase activity has been implicated in tumor angiogenesis and metastasis.
Industry:Pharmaceutical
A methylated tryptophan with anti-immunosuppressive activity. 1-methyl-d-tryptophan inhibits the enzyme indoleamine 2,3-dioxygenase (IDO), which degrades the essential amino acid tryptophan, and may increase or maintain tryptophan levels important to T cell function. Tryptophan depletion is associated with immunosuppression involving T cell arrest and anergy.
Industry:Pharmaceutical
A mixture of flavonolignans isolated from the milk thistle plant Silybum marianum. Silymarin may act as an antioxidant, protecting hepatic cells from chemotherapy-related free radical damage. This agent may also promote the growth of new hepatic cells.
Industry:Pharmaceutical
A methylated derivative of carmustine with antineoplastic activity. As an alkylating agent, semustine 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 metal complex compound of phthalocyanide with photosensitizing activity. Upon injection with photocyanide and subsequent introduction to photodynamic therapy (PDT), photocyanide becomes activated and forms reactive oxygen species that induce apoptosis.
Industry:Pharmaceutical
A methyl derivative of noroxymorphone with selective, opioid-receptor antagonistic activity. Methylnaltrexone displaces opioids from peripheral opioid receptors in the gastrointestinal tract, the bladder, and the skin, resulting in decreases in opioid-related constipation, urinary retention, and pruritis, respectively. Methylnaltrexone does not cross the blood-brain barrier and does not affect the centrally-mediated analgesic effect of opioids.
Industry:Pharmaceutical
A metabolite of A metabolite of icariin, a principal flavonoid glycoside in Herba Epimedii (a traditional Chinese medicine herb used in treating osteoporosis) with potential antineoplastic activity. ERa36 modulator icaritin selectively binds to a novel variant of estrogen receptor alpha, a36, and mediates a membrane-initiated "nongenomic" signaling pathway, which is linked to activated signaling pathways like the MAPK/ERK and the PI3K/Akt pathways. This agent induces cell cycle arrest at G1, or G2/M arrest depending upon the dose. Consistently with G1 arrest, icaritin increases protein expressions of pRb, p27(Kip1) and p16(Ink4a), while decreasing phosphorylated pRb, Cyclin D1 and CDK4. Forty percent of ER-negative breast cancer tumors express high levels of ERa36, and this subset of patients is less likely to benefit from tamoxifen treatment compared with those with ERa66-positive/ERa36-negative tumors.
