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 protein-bound polysaccharide derived from the mushroom Trametes versicolor (Turkey Tail) with immunoadjuvant and potential antitumor activities. Although its mechanism of action has yet to be fully elucidated, in vitro and in vivo studies indicate that polysaccharide-K induces peripheral blood monocyte secretion of IL-8 and TNF-alpha, induces T cell proliferation, and prevents cyclophosphamide-induced immunosuppression. This agent has also been reported to stimulate macrophages to produce reactive nitrogen intermediates and superoxide anions and to promote apoptosis in the promyelocytic leukemia cell line HL-60.

A protein that resides in the microbial wall of staphylococcus aureus and interferes with opsonization by binding to the Fc portion of immunoglobulin. The protein has a deleterious effect on the epithelial cells that line the respiratory tract, and plays a role in the induction of pneumonia. Protein A also initiates polymorphonuclear cell migration into airway passages via TNFR1 activation.
Industry:Pharmaceutical
A protein kinase inhibitor specific for the Raf and MEK mitogen-activated protein kinases (MAPKs) with potential anti-neoplastic activity. Raf/MEK dual kinase Inhibitor RO5126766 specifically inhibits the kinase activities of Raf and MEK, resulting in the inhibition of of target gene transcription that promotes malignant transformation of cells. Both Raf and MEK are serine/threonine-specific kinases that respond to extracellular stimuli, such as mitogens, and are involved in the regulation of cellular processes, such as gene expression, mitosis, differentiation, and apoptosis.
Industry:Pharmaceutical
A protein kinase inhibitor specific for the cyclin-dependent kinase 4 (CDK4) with potential antineoplastic activity. CDK4 inhibitor P1446A-05 specifically inhibits CDK4-mediated G1-S phase transition, arresting cell cycling and inhibiting cancer cell growth. The serine/threonine kinase CDK4 is found in a complex with D-type G1 cyclins and is the first kinase to become activated upon mitogenic stimulation, releasing cells from a quiescent stage into the G1/S growth cycling stage; CDK-cyclin complexes have been shown to phosphorylate the retinoblastoma (Rb) transcription factor in early G1, displacing histone deacetylase (HDAC) and blocking transcriptional repression.
Industry:Pharmaceutical
A protein comprised of segments of the extracellular domains of human vascular endothelial growth factor receptors 1 (VEGFR1) and 2 (VEGFR2) fused to the constant region (Fc) of human IgG1 with potential antiangiogenic activity. Afilbercept, functioning as a soluble decoy receptor, binds to pro-angiogenic vascular endothelial growth factors (VEGFs), thereby preventing VEGFs from binding to their cell receptors. Disruption of the binding of VEGFs to their cell receptors may result in the inhibition of tumor angiogenesis, metastasis, and ultimately tumor regression.
Industry:Pharmaceutical
A protease inhibitor used against human immunodeficiency virus (HIV). Lopinavir competitively inhibits the HIV-1 protease, an enzyme that mediates the cleavage of Gag, Gag-Pol and Nef precursor polypeptides into their mature proteins, including protease, reverse transcriptase, and integrase. Inhibition of HIV-1 protease prevents cleavage of the viral polyprotein precursor and results in the release of immature, noninfectious virions.
Industry:Pharmaceutical
A prostate cancer vaccine containing mRNAs encoding prostate specific antigen (PSA), prostate specific membrane antigen (PSMA), prostate stem cell antigen (PSCA) and six-transmembrane epithelial antigen of the prostate (STEAP), with potential antitumor activity. Upon administration, mRNA-derived prostate cancer vaccine CV9103 may stimulate the immune system to mount a cytotoxic T lymphocyte response (CTL) against PSA-, PSMA-, PSCA- and STEAP-expressing prostate tumor cells. The mRNA used in this vaccine is modified and formulated to have enhanced translational potency and adjuvant activities. . PSA, PSMA, PSCA and STEAP may be upregulated in prostate cancer cells; their expression in prostate cancer has been correlated with disease progression.

A proprietary, oral Chinese medicinal herb preparation with potential antioxidant, immunomodulating, and antineoplastic activities. THL-P (Tien-Hsien Liquid-P) contains fourteen Chinese medicinal herbs including: Cordyceps sinensis, Oldenlandia diffusa, Indigo pulverata levis, Polyporus umbellatus, Radix astragali, Panax ginseng, Solanum nigrum L. , Pogostemon cablin, Atractylodis macrocephalae rhizoma, Trichosanthes radix, Clematis radix, Margarite, Ligustrum lucidum Ait and Glycyrrhiza radix. Administered as an oral liquid, THL-P may modulate the activity of natural killer (NK) cells, cytotoxic T-lymphocytes (CTLs), macrophages and polymorphonuclear leukocytes, and enhance the secretion of interleukins (ILs) and interferon-gamma (IFN-gamma). This agent may also induce G2/M cell cycle arrest and downregulate several important oncogenic signaling pathways.
Industry:Pharmaceutical
A proprietary, miniature biodegradable polymeric matrix containing small-interfering RNAs for the mutated KRAS oncogene, KRASG12D, (siG12D), with potential antitumor activity. Upon intratumoral injection, siG12D is released locally, thereby preventing translation of KRAS proteins and potentially inhibiting growth of tumor cells overexpressing KRAS. KRAS, a member of the small GTPase superfamily, is mutated in over 90% of human pancreatic ductal adenocarcinomas (PDAC) and is associated with tumor cell proliferation and reduced survival.
Industry:Pharmaceutical
A proprietary transferrin receptor-targeted nanoparticle preparation of a non-chemically modified small-interfering RNA (siRNA) directed against the M2 subunit of ribonucleotide reductase (RRM2) with potential antineoplastic activity. Upon administration, transferrin receptor-targeted anti-RRM2 siRNA CALAA-01 binds to transferrin receptors (TfRs), releasing anti-RRM2 siRNA after endocytosis; anti-RRM2 siRNA silences the expression of RRM2 via the RNAi pathway, impeding the assembly of the holoenzyme ribonucleotide reductase (RR) which catalyzes the production of deoxyribonucleotides. As a result, inhibition of cellular proliferation may occur in cells expressing TfR, a cell surface protein overexpressed on various cancer cell types.
