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 tricyclic acridine-based (or carboxamide-based) drug with dual topoisomerase inhibitor and potential antineoplastic activities. Acridine carboxamide inhibits both topoisomerases I and II and intercalates into DNA, resulting in DNA damage, the disruption of DNA repair and replication, the inhibition of RNA and protein synthesis, and cell death.

A tricyclic indole poly(ADP-Ribose) polymerase (PARP1) inhibitor with potential chemosensitizing, radiosensitizing, and antineoplastic activities. PARP-1 inhibitor PF-01367338 selectively binds to PARP1 and inhibits PARP1-mediated DNA repair, thereby enhancing the accumulation of DNA strand breaks and promoting genomic instability and apoptosis. This may enhance the cytotoxicity of DNA-damaging agents and reverse tumor cell resistance to chemotherapy and radiation therapy. PARP1 catalyzes post-translational ADP-ribosylation of nuclear proteins and is activated by single-strand DNA (ssDNA) breaks.

A tri-Fab bispecific monoclonal antibody (BiMoAb) divalent for the carcinoembryonic antigen (CEA) and monovalent for histamine-succinyl-glycine (HSG) peptide-hapten radiolabeled with iodine I 131 (I131) with antigen-binding and radioisotopic activities. Iodine I 131-labeled anti-CEA/anti-HSG bispecific monoclonal antibody TF2 binds to the tumor-associated antigen (TAA) CEA on CEA-expressing tumor cells; these cells may then be radioimaged scintigraphically.

A tri-Fab bispecific monoclonal antibody (BiMoAb) divalent for the carcinoembryonic antigen (CEA) and monovalent for histamine-succinyl-glycine (HSG) peptide-hapten. Anti-CEA/anti-HSG bispecific monoclonal antibody TF2 binds to the tumor associated antigen (TAA) CEA on CEA-expressing tumor cells. Subsequently, an HSG peptide-hapten carrying a radionuclide is administered, binding to the anti-HSG binding fragment on the BiMoAb. Depending on the characteristics of the radionuclide used, CEA-expressing tumor cells may then be radioimaged and/or treated radioimmunotherapeutically.
Industry:Pharmaceutical
A trifunctional bispecific monoclonal antibody with potential antineoplastic activity. Catumaxomab has two antigen-recognition sites: one for human CD3, a T cell surface antigen; and one for human epithelial cell adhesion molecule (EpCAM), a cell surface antigen expressed by a variety of epithelial tumor cells. In addition, the modified Fc portion of this antibody binds Fc receptors on antingen presenting cells (APCs) such as macrophages and dendritic cells (DCs). Catumaxomab brings T cells, EpCAM-expressing epithelial tumor cells and APCs together into tricellular complexes, which may result in a potent cytotoxic T-lymphocyte (CTL) response against EpCAM-expressing epithelial tumor cells. Fc-mediated binding of APCs in the tricellular complex potentiates EpCAM antigen presentation to T cells and the activation of anti-tumor cytotoxic T cell functions.

A trifunctional bispecific monoclonal antibody with potential antineoplastic activity. FBTA05 contains two antigen-recognition sites: one for human CD3, a T cell surface antigen; and one for human CD20, a tumor-associated antigen that is exclusively expressed on B cells during most stages of B-cell development and often overexpressed in B-cell malignancies. In addition, the modified Fc portion of this antibody binds Fc receptors on antigen presenting cells (APCs) such as macrophages and dendritic cells (DCs). FBTA05 brings T cells, CD20-expressing tumor B-cells and APCs together into tricellular complexes, which may result in a potent cytotoxic T-lymphocyte (CTL) response against CD20-expressing tumor B-cells. Fc-mediated binding of APCs in the tricellular complex potentiates CD20 antigen presentation to T cells and the activation of anti-tumor cytotoxic T cells.
Industry:Pharmaceutical
A triglyceride prodrug of butyric acid with potential antineoplastic activity. Butyrate, the active metabolite of tributyrin, inhibits histone deacetylase, resulting in increased differentiation, decreased proliferation, cell cycle arrest, and apoptosis in some tumor cell lines.

A tripeptide comprised of three amino acids (cysteine, glutamic acid, and glycine) present in most mammalian tissue. Glutathione acts as an antioxidant, a free radical scavenger and a detoxifying agent. Glutathione is also important as a cofactor for the enzyme glutathione peroxidase, in the uptake of amino acids, and in the synthesis of leukotrienes. As a substrate for glutathione S-transferase, this agent reacts with a number of harmful chemical species, such as halides, epoxides and free radicals, to form harmless inactive products. In erythrocytes, these reactions prevent oxidative damage through the reduction of methemoglobin and peroxides. Glutathione is also involved in the formation and maintenance of disulfide bonds in proteins and in the transport of amino acids across cell membranes.

A tripeptide consisting of tyrosine, serine, and leucine with potential antineoplastic activity. Although the mechanism of its antitumor activity has yet to be fully elucidated, tyroserleutide appears to inhibit the expression of ICAM-1 (CD54), a cell adhesion factor of the immunoglobulin (Ig) superfamily that plays an important role in the invasion, adhesion, and metastasis of tumor cells. In addition, this agent may influence the Ca2+/calmodulin pathway, inhibiting phosphatidylinositol 3 kinase (PI3K); PI3K is upregulated in tumor cells and is involved in cellular proliferation.
Industry:Pharmaceutical
A triterpene quassinoid antineoplastic antibiotic isolated from the plant Brucea antidysenterica. Bruceantin inhibits the peptidyl transferase elongation reaction, resulting in decreased protein and DNA synthesis. Bruceantin also has antiamoebic and antimalarial activity.
