WARF Compound 42
(Other name for: warfarin)
warfarin
A synthetic anticoagulant. Warfarin appears to inhibit the regeneration of vitamin K1 epoxide and so the synthesis of vitamin K dependent clotting factors, which include Factors II, VII, IX and X, and the anticoagulant proteins C and S. This inhibition results in a sequential depression of Factors VII, IX, X and II activities. Vitamin K is an essential cofactor for the post ribosomal synthesis of the vitamin K dependent clotting factors. The vitamin promotes the biosynthesis of gamma-carboxyglutamic acid residues in these proteins which are essential for biological activity. Check for active clinical trials using this agent.

water O-15
An inert, radiopharmaceutical of oxygen-15 (O-15) labeled water used as a tracer molecule with positron emission tomography (PET). Upon administration, water O-15 is freely diffusible and its distribution, as well as its clearance, are completely dependent on the rate of blood flow. Water O-15 can be imaged using PET to measure tissue or tumor blood flow/perfusion. This cyclotron product has a very short half life of about 2 minutes thereby allowing for multiple, serial measurements. Check for active clinical trials using this agent. (NCI Thesaurus)
water-based vaginal lubricant

WEE1 inhibitor AZD1775
A small molecule inhibitor of the tyrosine kinase WEE1 with potential antineoplastic sensitizing activity. AZD1775 selectively targets and inhibits WEE1, a tyrosine kinase that phosphorylates cyclin-dependent kinase 1 (CDK1, CDC2) to inactivate the CDC2/cyclin B complex. Inhibition of WEE1 activity prevents the phosphorylation of CDC2 and impairs the G2 DNA damage checkpoint. This may lead to apoptosis upon treatment with DNA damaging chemotherapeutic agents. Unlike normal cells, most p53 deficient or mutated human cancers lack the G1 checkpoint as p53 is the key regulator of the G1 checkpoint and these cells rely on the G2 checkpoint for DNA repair to damaged cells. Annulment of the G2 checkpoint may therefore make p53 deficient tumor cells more vulnerable to antineoplastic agents and enhance their cytotoxic effect. Check for active clinical trials using this agent. (NCI Thesaurus)
Welchol
(Other name for: colesevelam hydrochloride)
Wellbutrin
(Other name for: bupropion hydrochloride)
Wellcovorin

wheatgrass juice
The juice extracted from the mature sprouts of wheatgrass, Triticum aestivum, which is a member of the Poaceae family, with potential anti-inflammatory, immunomodulating and chemopreventive activities. Wheatgrass juice contains many vitamins, including A, B vitamins, C and E, minerals, including selenium, iron, magnesium, calcium, manganese, copper and zinc, amino acids, chlorophyll and a number of antioxidant enzymes, including superoxide dismutase and cytochrome oxidase. Although the exact mechanism(s) of action through which wheatgrass juice exerts its effect(s) has yet to be fully elucidated, the components in the juice may scavenge free radicals, reduce chemotherapy-induced myelotoxicity, neutralize toxins and carcinogens and modulate the levels of certain pro-inflammatory cytokines, such as interleukin (IL)- 6, IL-8, IL-10 and IL-12. Check for active clinical trials using this agent. (NCI Thesaurus)
whey protein isolate
A biologically active, cystine-rich, whey-based protein isolate. Whey protein isolate is broken down in the body into cystine and glutamylcystine, which travel safely in the blood stream, upon cell entry, deliver a sustained amount of free cysteine to the cells. The available cysteine allows cells to synthesize glutathione (GSH), a tripeptide containing amino acids glycine, glutamate and cysteine, thereby maintaining and increasing intracellular GSH concentrations. GSH plays a major role as an antioxidant, thereby protecting cells from oxidative damage due to harmful substances such as free radicals and reactive oxygen compounds. Check for active clinical trials using this agent. (NCI Thesaurus)
white button mushroom extract
A heat-stable extract of white button mushrooms (Agaricus bisporus) with potential chemopreventive and immunomodulating activities. Phytochemicals, such as polysaccharides and especially beta-D-glucans found in the white button mushroom extract, bind to and inhibit the activity of aromatase, an enzyme responsible for the conversion of androgens to estrogens and which is often upregulated in breast cancer cells. The consequent decrease in estrogen production may result in the suppression of estrogen-dependent cellular proliferation. In addition, this extract may promote dendritic cell (DC) maturation, increase interferon gamma (IFN-gamma) and tumor necrosis factor alpha (TNF-alpha) production, and may enhance natural killer (NK) cell activity, thus amplifying both innate and T cell-mediated immune responses against cancer cells. Check for active clinical trials using this agent. (NCI Thesaurus)
white carrot
A vegetable, also known as Arracacha, with potential chemoprevenitve, anti-oxidant and protective activities. White carrot contains a variety of nutrients, including minerals and vitamins. Polyacetylenes, including falcarinol, falcarindiol and falcarindiol-3-acetate are mainly responsible for its potential anti-cancer activity. Check for active clinical trials using this agent. (NCI Thesaurus)
white wine
An alcoholic beverage made from fermented white grapes with potential orexigenic activity. Although not well understood, the mechanism for white wine's potential orexigenic activity may be due, in part, to its alcohol content and may involve alterations in neurotransmitter and hormone activities related to appetite regulation. Check for active clinical trials using this agent. (NCI Thesaurus)
wild-type reovirus
A serotype 3 Dearing strain (T3D) of reovirus (Respiratory Enteric Orphan virus) with potential oncolytic activity. Reovirus, a dsRNA virus, is able to replicate specifically in cancer cells bearing an activated Ras pathway. In contrast to normal cells, two-thirds of human cancer cells are Ras-activated. Unlike normal cells, Ras-activated tumor cells are deficient in host cellular protein kinase R (PKR) activity and so are unable to mount an antiviral response. In Ras-activated tumor cells, reovirus freely replicates and induces apoptosis; tumor cell lysis frees progeny viral particles to infect surrounding tumor cells. A cycle of infection, replication and cell death may continue until Ras-activated tumor cells are eradicated. PKR (eukaryotic translation initiation factor 2-alpha kinase 2) is activated by viral synthesis of double-stranded RNA and is an important component of innate immunity in vertebrates, protecting against viral infection.

Winobanin
(Other name for: danazol)
WinRho SDF
(Other name for: therapeutic immune globulin)
Wnt-5a mimic hexapeptide foxy-5
A formylated, six amino acid, Wnt5a-derived peptide and wnt-5a mimetic with potential anti-metastatic activity. Upon intravenous administration, Wnt-5a mimic hexapeptide foxy-5 binds to and activates the wnt-5a receptors, Frizzled-2 and -5, which activates wnt-5a-mediated signaling. Increased wnt-5a signaling may inhibit endothelial tumor cell migration and invasion. This may decrease metastasis of susceptible tumor cells. However, foxy-5 does not affect tumor cell proliferation or apoptosis. Foxy-5 lacks a heparan sulfate-binding domain and contains a formyl group on its NH2-terminal methionine residue which decreases in vivo degradation. Decreased expression of wnt-5a protein is associated with increased motility of certain tumor cell types. Check for active clinical trials using this agent. (NCI Thesaurus)
