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 2-nitroimidazole with radiosensitizing properties. Etanidazole depletes glutathione and inhibits glutathione transferase, thereby enhancing the cytotoxicity of ionizing radiation. This agent may also be useful as an imaging agent for identifying hypoxic, drug-resistant regions of primary tumors or metastases.
Industry:Pharmaceutical
A 3-cyanoquinoline pan-ErbB tyrosine kinase inhibitor with potential antineoplastic activity. Pelitinib irreversibly binds covalently to epidermal growth factor receptors (EGFR) ErbB-1, -2 and -4, thereby inhibiting receptor phosphorylation and signal transduction and resulting in apoptosis and suppression of proliferation in tumor cells that overexpress these receptors.
Industry:Pharmaceutical
A 2-nitroimidazole labeled with the positron-emitting radioisotope fluorine F 18. HX4, the 2-nitroimidazole moiety of (F-18)HX4, is selectively bioreduced and bound in hypoxic tumor cells, permitting the imaging of hypoxic tumor cells with positron emission tomography (PET).
Industry:Pharmaceutical
A 2-aminothiazole-derived, small-molecule cyclin dependent kinase (CDK) inhibitor with potential antineoplastic activity. CDK inhibitor SNS-032 selectively binds to CDKs 2, 7, and 9, preventing their phosphorylation and activation; inhibition of CDK activity may result in cell cycle arrest, the induction of apoptosis and decreased tumor cell proliferation in susceptible tumor cell populations. This agent has been shown to sensitize radioresistant tumor cells to ionizing radiation.

A 2-amino acid compound with immunomodulatory activity. L-leucyl-L-leucine methyl ester (LLME) is a lysosomotropic agent entering cells via receptor-mediated endocytosis. LLME undergoes a condensation process catalyzed by dipeptidyl peptidase I (DPPI) in lysosomes. Condensation of LLME leads to lysosomal rupture and DNA fragmentation in DPPI-expressing immune cells such as cytotoxic T-cells and natural killer cells. Therefore, this agent may be able to decrease the incidence of graft versus host disease (GVHD) via cytotoxic T-cell depletion. Furthermore, LLME has the potential for augmenting antibody production when used in pretreatment of peripheral blood mononuclear cells (PBMCs), possibly by interfering with gene expression of inflammatory factors.
Industry:Pharmaceutical
A 26-base guanine-rich oligodeoxynucleotide aptamer with potential apoptotic induction activity. Upon administration, anti-nucleolin aptamer AS1411 targets and binds to nucleolin, a nucleolar phosphoprotein which is overexpressed on the surface of certain cancer cells. Via binding to cell surface nucleolin, AS1411 is internalized and may prevent nucleolin from binding to and stabilizing mRNA of the anti-apoptotic BCL2, thereby destabilizing BCL2 mRNA, leading to a reduction in BCL2 protein synthesis. This may lead to the induction of apoptosis.
Industry:Pharmaceutical
A 20-mer antisense oligonucleotide complementary to a coding region in the mRNA of the R2 small subunit component of human ribonucleotide reductase. GTI-2040 decreases mRNA and protein levels of R2 in vitro and may inhibit tumor cell proliferation in human tumors in vivo.
Industry:Pharmaceutical
A 0. 1% topical formulation of uracil used to potentially lower the incidence of hand-foot syndrome (HFS) (or palmar-plantar erythrodysesthesia) during 5-fluorouracil (5-FU) or 5-FU prodrug capecitabine chemotherapy. Upon local administration of uracil ointment to the skin, uracil competes with capecitabine or 5-FU as substrates for the activating enzyme thymidine phosphorylase and the metabolizing enzyme dihydropyrimidine dehydrogenase. This may prevent the production of 5-FU as well as the breakdown of 5-FU into the toxic metabolites locally. As the 5-FU metabolites are responsible for the presentation of HFS, inhibiting their formation may prevent this adverse effect. By applying a high concentration of uracil locally, the skin toxicities of 5-FU may be countered while preserving the systemic anti-cancer activity of the 5FU.
Industry:Pharmaceutical
A 24-base phosphorothiolate antisense oligodeoxynucleotide (ODN) for the proto-oncogene c-myb with potential antineoplastic activity. C-myb antisense oligonucleotide G4460 binds to codon sequences 2 to 9 of c-myb mRNA, inhibiting translation of the transcript. Suppression of c-myb expression with this agent may result in the restoration of normal differentiation pathways, increased antiproliferative effects, and the induction of apoptosis in early progenitor hematopoietic cells and in tumor cells that overexpress c-myb. Tumor-cell overexpression of c-myb blocks differentiation, promotes proliferation, and inhibits apoptosis.
Industry:Pharmaceutical
A "true human" (cloned from human B lymphocytes) monoclonal antibody directed against interleukin-1 alpha (IL1a) with potential antineoplastic activity. Anti-IL-1 alpha monoclonal antibody CA-18C3 binds to IL1a and may block the activity of IL1a. IL1a, an inflammatory mediator, plays a key role in interleukin-mediated tumor cell activity such as angiogenesis, tissue matrix remodeling, metastasis and tumor cell invasion.
