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 polymeric nanoparticle (PNP) formulation containing the taxane docetaxel, a semi-synthetic analogue of paclitaxel, with antineoplastic activity. Docetaxel binds specifically to the beta-tubulin subunit of the microtubule, stabilizing tubulin and inhibiting microtubule disassembly, which results in cell-cycle arrest at the G2/M phase, preventing cell proliferation. This agent also inhibits pro-angiogenic factors such as vascular endothelial growth factor (VEGF) and induces various mediators of the inflammatory response. Compared to docetaxel alone, the PNP formulation may enhance stability and improve delivery.
Industry:Pharmaceutical
A polyglutamatable folate antagonist analogue of methotrexate with antineoplastic activity. Edatrexate inhibits dihydrofolate reductase, thereby increasing cellular levels of polyglutamates, inhibiting thymidylate synthase and glycinamide ribonucleotide formyl transferase, impairing synthesis of purine nucleotides and amino acids, and resulting in tumor cell death. Edatrexate may overcome tumor resistance to methotrexate, which loses its activity after it is polyglutamated.
Industry:Pharmaceutical
A polyethylene glycol-based solution containing polyethylene glycol (PEG) 3350 (macrogol 3350) and electrolytes with laxative activity. As an orally administered nonabsorbable osmotic agent, PEG 3350 increases fecal water content and decreases gastrointestinal transit time.
Industry:Pharmaceutical
A polyethylene glycol (PEG) conjugate of 7-ethyl-10-hydroxycamptothecin with potential antineoplastic activity. After hydrolysis in vivo, 7-ethyl-10-hydroxycamptothecin (SN38), an active metabolite of irinotecan, is released from polyethyleneglycol-7-ethyl-10-hydroxycamptothecin (PEG-SN38); 7-ethyl-10-hydroxycamptothecin selectively stabilizes topoisomerase I-DNA covalent complexes, resulting in single-stranded and double-stranded DNA breaks, the inhibition of DNA replication, and the induction of apoptosis. This agent is designed to deliver the active metabolite to tumor cells without the need for conversion as is the case with irinotecan. Compared to unPEGylated 7-ethyl-10-hydroxycamptothecin, PEGylation improves solubility and allows for parental delivery, and may result in a longer half-life and higher exposure for tumor cells.
Industry:Pharmaceutical
A polycarbonate-based semicylindrical plaque impregnated with yttrium Y 90 with radioisotopic and antineoplastic activities. An yttrium-90 polycarbonate brachytherapy plaque may be applied to a tumor site with a special brachytherapy applicator for a predetermined interval of time, selectively delivering a cytotoxic dose of beta-emitting yttrium Y 90.
Industry:Pharmaceutical
A polydeoxyribonucleotide with antithrombotic, thrombolytic, and fibrinolytic properties. Defibrotide induces the release of prostaglandin 12 and reduces the expression of adhesion molecules on endothelial cells, thereby interfering with platelet and leukocyte adhesion to the endothelium.
Industry:Pharmaceutical
A poly(ADP-ribose) polymerase (PARP) -1 and -2 inhibitor with chemosensitizing and antitumor activities. With no antiproliferative effects as a single agent at therapeutic concentrations, ABT-888 inhibits PARPs, thereby inhibiting DNA repair and potentiating the cytotoxicity of DNA-damaging agents. PARP nuclear enzymes are activated by DNA single or double strand breaks, resulting in the poly(ADP-ribosyl)ation of other nuclear DNA binding proteins involved in DNA repair; poly(ADP-ribosyl)ation contributes to efficient DNA repair and to survival of proliferating cells exposed to mild genotoxic stresses as induced by as oxidants, alkylating agents or ionizing radiation.
Industry:Pharmaceutical
A polar organic solvent. DMSO is a free radical scavenger that has been used to treat extravasation damage caused by anthracycline-based chemotherapy.
Industry:Pharmaceutical
A plasmid vaccine encoding wild type human carcinoembryonic antigen (CEA) fused to a tetanus toxoid T helper epitope, with potential antineoplastic activity. Upon vaccination and subsequent intradermal electroporation, CEA/tetanus toxoid T helper epitope fusion protein-expressing DNA plasmid vaccine may stimulate the immune system to mount a cytotoxic T-lymphocyte (CTL) response against CEA-expressing tumor cells. CEA, a tumor associated antigen, is overexpressed in a variety of cancer cell types. The tetanus toxoid helper peptide epitope, obtained from the bacterial Clostridium tetani toxoid, binds to class II MHC molecules and increases the helper T-cell response thereby inducing an increased and long-term immune response.
Industry:Pharmaceutical
A platinum(IV) analogue with antineoplastic activity. Ormaplatin alkylates DNA, forming both inter- and intra-strand platinum-DNA crosslinks, which result in inhibition of DNA replication and transcription and cell-cycle nonspecific cytotoxicity.
