Cancer Drugs

- D -

  • D1/3-MAGE-3-His fusion protein

  • A recombinant, chimeric protein derived from a melanoma antigenic epitope (MAGE-3) and recognized by specific cytotoxic T lymphocytes. MAGE-3, a human peptide epitope present in the cytosol of melanoma cells, may be expressed as the fusion protein D1/3-Mage-3; this fusion protein may boost antitumoral immune responses when used in a vaccine formulation.

  • dacarbazine

  • A triazene derivative with antineoplastic activity. Dacarbazine alkylates and cross-links DNA during all phases of the cell cycle, resulting in disruption of DNA function, cell cycle arrest, and apoptosis.

  • daclizumab

  • A recombinant monoclonal antibody interleukin-2 receptor antagonist. Daclizumab binds specifically to the alpha subunit of the human interleukin-2 (IL-2) receptor expressed on the surface of activated lymphocytes in vivo, thereby inhibiting IL-2 binding and IL-2-mediated lymphocyte activation, a critical cellular immune response pathway.

  • Dacogen

  • (Other name for: decitabine)

  • dactinomycin

  • A chromopeptide antineoplastic antibiotic isolated from the bacterium Streptomyces parvulus. Dactinomycin intercalates between adjacent guanine-cytosine base pairs, blocking the transcription of DNA by RNA polymerase; it also causes single-strand DNA breaks, possibly via a free-radical intermediate or an interaction with topoisomerase II.

  • dalteparin

  • A low molecular weight, synthetic heparin. As an anticoagulant/antithrombotic agent, dalteparin binds to antithrombin and enhances the inhibition of Factor Xa. Compared to unfractionated heparins, the use of dalteparin is associated with lower incidences of osteoporosis and heparin-induced thrombocytopenia.

  • dapsone

  • A synthetic derivative of diamino-sulfone with anti-mycobacterial and anti-malarial properties. A structural analog of p-aminobenzoic acid (PABA), dapsone inhibits dihydropteroate synthase (DHPS), an enzyme important in folate synthesis, resulting in a depletion of the folate pool and a reduction in the amount of thymidylate available for DNA synthesis.

  • daptomycin

  • A semi-synthetic cyclic lipopeptide antibiotic isolated form the bacterium Streptomyces roseosporus with broad-spectrum anitbiotic activity against Gram-positive bacteria. Daptomycin has a distinct mechanism of action, in which it binds to bacterial membrane and causes rapid depolarization of the cell membrane due to calcium-dependant potassium efflux; the loss of membrane potential leads to inhibition of DNA, RNA and protein synthesis, resulting in bacterial cell death. This agent does not penetrate the outer membrane of gram-negative bacteria.

  • darbepoetin alfa

  • A recombinant analog of the endogenous cytokine erythropoietin, an erythropoiesis-stimulating protein. Due to the addition of two carbohydrate chains, darbepoetin alfa exhibits a three-fold greater half-life than does erythropoietin. Similar to erythropoietin, darbopoietin alfa binds to and activates epoetin receptors, thereby inducing the differentiation and maturation of erythrocyte progenitors, stimulating endothelial cell proliferation, and stimulating B-cell proliferation and immunoglobulin production.

  • dasatinib

  • An orally bioavailable synthetic small molecule-inhibitor of SRC-family protein-tyrosine kinases. Dasatinib binds to and inhibits the growth-promoting activities of these kinases. Apparently because of its less stringent binding affinity for the BCR-ABL kinase, dasatinib has been shown to overcome the resistance to imatinib of chronic myeloid leukemia (CML) cells harboring BCR-ABL kinase domain point mutations. SRC-family protein-tyrosine kinases interact with variety of cell-surface receptors and participate in intracellular signal transduction pathways; tumorigenic forms can occur through altered regulation or expression of the endogenous protein and by way of virally-encoded kinase genes.

  • daunorubicin hydrochloride

  • The hydrochloride salt of an anthracycline antineoplastic antibiotic with therapeutic effects similar to those of doxorubicin. Daunorubicin exhibits cytotoxic activity through topoisomerase-mediated interaction with DNA, thereby inhibiting DNA replication and repair and RNA and protein synthesis.

  • DaunoXome

  • (Other name for: liposomal daunorubicin citrate)

  • D-cycloserine

  • An analogue of the amino acid D-alanine with broad-spectrum antibiotic and glycinergic activities. D-cycloserine interferes with bacterial cell wall synthesis by competitively inhibiting two enzymes, L-alanine racemase and D-alanine:D-alanine ligase, thereby impairing peptidoglycan formation necessary for bacterial cell wall synthesis. This agent may be bactericidal or bacteriostatic, depending on its concentration at the infection site and the susceptibility of the organism. In addition, D-cycloserine is an excitatory amino acid and partial agonist at the glycine binding site of the NMDA receptor in the central nervous system (CNS); binding to the central NMDA receptor may result in amelioration of neuropathic pain.

  • Decaspray

  • (Other name for: dexamethasone)

  • decitabine

  • A cytidine antimetabolite analogue with potential antineoplastic activity. Decitabine incorporates into DNA and inhibits DNA methyltransferase, resulting in hypomethylation of DNA and intra-S-phase arrest of DNA replication.

  • Deenar

  • (Other name for: dexamethasone)

  • deferasirox

  • A synthetic, orally available, achiral, tridentate triazole derived from salicylic acid with iron chelator properties. Deferasirox chelates iron at a 2:1 (ligand:iron) ratio. Because of its oral availablity,and long plasma half-life, this agent may be superior to desferrioxamine (desferal, DFO), which is orally inactive and has a short plasma half-life.

  • defibrotide

  • 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.

  • degarelix

  • A long-acting, synthetic peptide with gonadotrophin-releasing hormone (GnRH) antagonistic properties. Degarelix targets and blocks GnRH receptors located on the surfaces of gonadotroph cells in the anterior pituitary, thereby reducing secretion of luteinizing hormone (LH) by pituitary gonadotroph cells and so decreasing testosterone production by interstitial (Leydig) cells in the testes.

  • dehydroepiandrosterone

  • A synthetic form of dehydroepiandrosterone with potential chemopreventive activity. Produced endogenously, dehydroepiandrosterone (DHEA) is an intermediate in the conversion of cholesterol to androgens and estrogens. Although the mechanisms of action of exogenously administered DHEA have not been fully illuminated, they may result in both direct and indirect physiologic effects. Direct effects include GABA-a receptor complex and NMDA receptor modulation, and enhanced pancreatic beta cell insulin secretion and antiglucocorticoid activities.

  • Delatestryl

  • (Other name for: therapeutic testosterone)

  • delta-8-tetrahydrocannabinol

  • An analogue of tetrahydrocannabinol (THC) with antiemetic, anxiolytic, appetite-stimulating, analgesic, and neuroprotective properties. Delta-8-tetrahydrocannabinol (delta-8-THC) binds to the cannabinoid G-protein coupled receptor CB1, located in the central nervous system; CB1 receptor activation inhibits adenyl cyclase, increases mitogen-activated protein kinase activities, modulates several potassium channel conductances and inhibits N- and P/Q-type Ca2+ channels. This agent exhibits a lower psychotropic potency than delta-9-tetrahydrocannabinol (delta-9-THC), the primary form of THC found in cannabis.

  • Delta-Cortef

  • (Other name for: prednisolone)

  • Deltasone

  • (Other name for: prednisone)

  • demineralized bone matrix

  • Demineralized allograft bone with osteoinductive activity. Demineralized bone matrices are prepared by acid extraction of allograft bone, resulting in loss of most of the mineralized component but retention of collagen and noncollagenous proteins, including growth factors. The efficacy of a demineralized bone matrix (DBM) as a bone-graft substitute or extender may be related to the total amount of bone morphogenetic protein (BMP) present, and the ratios of the different BMPs present. BMPs belong to the transforming growth factor (TGF) superfamily of proteins.

  • dendritic cell-CEA peptide vaccine

  • A cancer vaccine consisting of dendritic cells harvested from a patient with cancer and pulsed or transduced with a peptide fragment of carcinoembryonic antigen (CEA), a tumor-associated antigen expressed by a wide range of cancers. When the altered dendritic cells are returned to the patient, they may stimulate the host immune system to mount a cytotoxic T-lymphocyte immune response against tumor cells expressing CEA.

  • dendritic cell-MART-1 peptide vaccine

  • A cancer vaccine consisting of dendritic cells harvested from a patient with cancer and pulsed or transduced with a peptide fragment of MART-1 (melanoma antigen recognized by T-cells), an antigen expressed by melanoma cells. When the altered dendritic cells are returned to the patient, they stimulate the host immune system to mount a cytotoxic T-lymphocyte immune response against tumor cells expressing MART-1.

  • denileukin diftitox

  • A cytotoxic recombinant protein consisting of interleukin-2 (IL-2) protein sequences fused to diphtheria toxin. The IL-2 protein sequence moiety of denileukin difitox directs the cytocidal action of diphtheria toxin to cells that express IL-2 receptors. After the toxin moiety is internalized into target IL-2 receptor-expressing cells, its catalytic domain catalyzes the transfer of the ADP-ribose moiety of NAD to a posttranslationally modified histidine residue of elongation factor 2 (EF-2), called diphthamine. This covalent modification inactivates EF-2 and disrupts polypeptide chain elongation, resulting in cell death.

  • denosumab

  • A humanized monoclonal antibody directed against the receptor activator of nuclear factor kappa beta ligand (RANKL) with antiosteoclast activity. Denosumab specifically binds to RANKL and blocks the interaction of RANKL with RANK, a receptor located on osteoclast cell surfaces, resulting in inhibition of osteoclast activity, a decrease in bone resorption, and a potential increase in bone mineral density. RANKL, a protein expressed by osteoblastic cells, plays an important role in osteoclastic differentiation and activation.

  • Depakene

  • (Other name for: valproic acid)

  • DepoFoam

  • (Other name for: cytarabine (liposomal))

  • Depo-Medrol

  • (Other name for: methylprednisolone)

  • Depo-Provera

  • (Other name for: medroxyprogesterone)

  • Dermacort

  • (Other name for: hydrocortisone)

  • Deronil

  • (Other name for: dexamethasone)

  • deslorelin

  • A synthetic nonapeptide analogue of the natural gonadotrophin releasing hormone (GnRH) with potential antineoplastic activity. Deslorelin binds to and activates pituitary gonadotropin releasing hormone (GnRH) receptors. Continuous, prolonged administration of goserelin in males results in pituitary GnRH receptor desensitization and inhibition of pituitary secretion of follicle stimulating hormone (FSH) and luteinizing hormone (LH), leading to a significant decline in testosterone production; in females, prolonged administration results in a decrease in estradiol production.

  • Detox-B adjuvant

  • A cancer vaccine adjuvant that consists of an oil droplet emulsion of monophosphoryl lipid A and mycobacterial cell wall skeleton. Detox-B adjuvant is a non-specific immunostimulant that may enhance the host immune response to certain cancer vaccines. Detox-B differs from Detox adjuvant in that Detox-B contains lecithin.

  • dexamethasone

  • A synthetic adrenal corticosteroid with potent anti-inflammatory properties. In addition to binding to specific nuclear steroid receptors, dexamethasone also interferes with NF-kB activation and apoptotic pathways. This agent lacks the salt-retaining properties of other related adrenal hormones.

  • dexrazoxane hydrochloride

  • The hydrochloride salt of a bisdioxopiperazine with cardioprotective and antineoplastic activities. After hydrolysis to an active form that is similar to ethylenediaminetetraacetic acid (EDTA), dexrazoxane chelates iron, thereby preventing the metal-catalyzed formation of reactive oxygen radicals produced by anthracycline antibiotics such as doxorubicin. This agent also inhibits the catalytic activity of topoisomerase II, resulting in cell growth inhibition.

  • dextroamphetamine-amphetamine

  • A combination of two synthetic agents with central nervous system stimulant activity. Both agents are non-catecholamine, sympathomimetic agents that elevate blood pressure and cause bronchodilation. These agents are commonly abused psychostimulant drugs that induce psychologic dependence manifested by elevated mood, increased wakefulness, concentration, physical performance and a feeling of well-being. Tolerance to various effects develops unequally, so that tachycardia and enhanced alertness diminish while psychotoxic effects (hallucinations and delusions) may occur.

  • Dezone

  • (Other name for: dexamethasone)

  • DHA-paclitaxel

  • A prodrug comprised of the naturally occurring omega-3 fatty acid docosahexaenoic acid (DHA) covalently conjugated to the anti-microtubule agent paclitaxel. Because tumor cells take up DHA, DHA-paclitaxel is delivered directly to tumor tissue, where the paclitaxel moiety binds to tubulin and inhibits the disassembly of microtubules, thereby resulting in the inhibition of cell division. Paclitaxel also induces apoptosis by binding to and blocking the function of the apoptosis inhibitor protein Bcl-2 (B-cell Leukemia 2). DHA-paclitaxel exhibits improved pharmacokinetic and toxicity profiles when compared to conventional paclitaxel and has demonstrated antineoplastic activity in animal models of cancer.

  • diazoxide

  • A benzothiadiazine derivate with antihypertensive and hyperglycemic activities. Diazoxide increases membrane permeability to potassium ions in vascular smooth muscle, thereby stabilizing the membrane action potential and preventing vascular smooth muscle contraction; this results in peripheral vasodilatation and decreases in peripheral vascular resistance. This agent also inhibits insulin release by interacting with ATP-sensitive potassium channels of pancreatic islet beta-cells.

  • Difflam

  • (Other name for: benzydamine hydrochloride)

  • Diflucan

  • (Other name for: fluconazole)

  • digoxin

  • A cardiac glycoside. Digoxin inhibits the sodium potassium adenosine triphosphatase (ATPase) pump, thereby increasing intracellular calcium and enhancing cardiac contractility. This agent also acts directly on the atrioventricular node to suppress conduction, thereby slowing conduction velocity. Apparently due to its effects on intracellular calcium concentrations, digoxin induces apoptosis of tumor cells via a pathway involving mitochondrial cytochrome c and caspases 8 and 3.

  • dihydrotestosterone

  • The most potent androgen, required for sex development. Dihydrotestosterone is synthesized from testosterone in the prostate gland, testes, hair follicles and adrenal glands by 5-alpha reductase. Dihydrotestosterone exerts its action similar to testosterone, which binds to and activates specific nuclear androgen receptors. After translocation into the nucleus, the activated hormone-receptor complex binds to the androgen response elements on the DNA and activates gene expressions that are required for sex development. Dihydrotestosterone is responsible for the formation of male primary sex characteristics and most male secondary sex characteristics during puberty, such as muscular growth, facial and body hair growth, and deepening of the voice.

  • diindolylmethane

  • A phytonutrient and plant indole found in cruciferous vegetables including broccoli, brussels sprouts, cabbage, cauliflower and kale, with potential antiandrogenic and antineoplastic activities. As a dimer of indole-3-carbinol, diindolylmethane (DIM) promotes beneficial estrogen metabolism in both sexes by reducing the levels of 16-hydroxy estrogen metabolites and increasing the formation of 2-hydroxy estrogen metabolites, resulting in increased antioxidant activity. Although this agent induces apoptosis in tumor cells in vitro, the exact mechanism by which DIM exhibits its antineoplastic activity in vivo is unknown.

  • Dimericine

  • (Other name for: T4N5 liposomal lotion)

  • dimesna

  • A synthetic derivative of dithio-ethane sulfonate with uroprotective properties. In the kidney, dimesna undergoes reduction to the free thiol compound, mesna, which reacts chemically with the urotoxic ifosfamide metabolites acrolein and 4-hydroxy-ifosfamide, resulting in their detoxification. This agent also inhibits cyclophosphamide-induced hemorrhagic cystitis.

  • dimethylxanthenone acetic acid

  • A fused tricyclic analogue of flavone acetic acid with potential antineoplastic activity. Dimethylxanthenone acetic acid induces the cytokines tumor necrosis alpha (TNF-alpha), serotonin and nitric oxide, resulting in hemorrhagic necrosis and a decrease in angiogenesis. This agent also stimulates the anti-tumor activity of tumor-associated macrophages.

  • Diovan

  • (Other name for: valsartan)

  • Disalcid

  • (Other name for: sodium salicylate)

  • Disulone

  • (Other name for: dapsone)

  • DJ-927

  • A semi-synthetic orally-available taxane derivative with potent antineoplastic properties. DJ-927 binds to tubulin, promoting microtubule assembly and stabilization and preventing microtubule depolymerization, thereby inhibiting cell proliferation. As it represents poor substrate for P-glycoprotein-related drug resistance mechanisms, this agent may be useful for treating multi-drug resistant tumors. DJ-927I is more potent than paclitaxel and docetaxel and is the first oral taxane derivative.

  • docetaxel

  • A semi-synthetic, second-generation taxane derived from a compound found in the European yew tree, Taxus baccata. Docetaxel displays potent and broad antineoplastic properties; it binds to and stabilizes tubulin, thereby inhibiting microtubule disassembly which results in cell- cycle arrest at the G2/M phase and cell death. This agent also inhibits pro-angiogenic factors such as vascular endothelial growth factor (VEGF) and displays immunomodulatory and pro-inflammatory properties by inducing various mediators of the inflammatory response. Docetaxel has been studied for use as a radiation-sensitizing agent.

  • dolasetron mesylate

  • An indole derivative with antiemetic activity. As a selective serotonin receptor antagonist, dolasetron mesylate competitively blocks the action of serotonin at 5HT3 receptors, resulting in suppression of chemotherapy- and radiotherapy-induced nausea and vomiting.

  • Domolene-HC

  • (Other name for: hydrocortisone)

  • donepezil hydrochloride

  • The hydrochloride salt of a piperidine derivative with neurocognitive-enhancing activity. Donepezil reversibly inhibits acetylcholinesterase, thereby blocking the hydrolysis of the neurotransmitter acetylcholine and, consequently, increasing its activity. This agent may improve neurocognitive function in Alzheimer's disease, reduce sedation associated with opioid treatment of cancer pain, and improve neurocognitive function in patients who have received radiation therapy for primary brain tumors or brain metastases.

  • doxercalciferol

  • A synthetic analog of vitamin D with potential antineoplastic activity. In the liver, doxercalciferol is converted to its biologically active vitamin D metabolites, which control the intestinal absorption of dietary calcium, the tubular reabsorption of calcium by the kidney and, in conjunction with parathyroid hormone (PTH), the mobilization of calcium from the skeleton. Through interaction with specific receptor proteins in target tissues, these vitamin D metabolites act directly on osteoblasts to stimulate skeletal growth, and on the parathyroid glands to suppress PTH synthesis and secretion. This agent has also been shown to inhibit the growth of retinoblastomas, and may exhibit some antiproliferative activity against prostate cancer cells.

  • doxifluridine

  • A fluoropyrimidine derivative and oral prodrug of the antineoplastic agent 5-fluorouracil (5-FU) with antitumor activity. Doxifluridine, designed to circumvent the rapid degradation of 5-FU by dihydropyrimidine dehydrogenase in the gut wall, is converted into 5-FU in the presence of pyrimidine nucleoside phosphorylase. 5-FU interferes with DNA synthesis and subsequent cell division by reducing normal thymidine production and interferes with RNA transcription by competing with uridine triphosphate for incorporation into the RNA strand.

  • DOXIL

  • (Other name for: doxorubicin hydrochloride liposome)

  • doxorubicin hydrochloride

  • The hydrochloride salt of doxorubicin, an anthracycline antineoplastic antibiotic isolated from the fungus Streptococcus peucetius var. caesius. Doxorubicin intercalates into DNA and interacts with topoisomerase II, thereby inhibiting DNA replication and repair and RNA and protein synthesis. This agent also produces toxic free-radical intermediates and interacts with cell membrane lipids causing lipid peroxidation.

  • doxorubicin hydrochloride liposome

  • A liposome-encapsulated form of the hydrochloride salt of the anthracycline antineoplastic antibiotic doxorubicin. Liposomal delivery of doxorubicin improves drug penetration into tumors and decreases drug clearance, thereby increasing the duration of therapeutic drug effects. Doxorubicin intercalates into DNA and interacts with topoisomerase II, consequently inhibiting DNA replication and repair and RNA and protein synthesis. This agent also produces toxic free-radical intermediates and interacts with cell membrane lipids causing lipid peroxidation.

  • doxorubicin-magnetic targeted carrier complex

  • Anthracycline antineoplastic antibiotic doxorubicin bound to microscopic beads of activated carbon and iron (magnetic targeted carriers). With placement of a magnet on the body surface overlying a tumor site, this carrier complex delivers doxorubicin directly to the tumor, thereby prolonging the duration of the therapeutic effects while decreasing its systemic toxicity. Doxorubicin intercalates into DNA and interacts with topoisomerase II, thereby inhibiting DNA replication and repair and RNA and protein synthesis. This agent also produces toxic free-radical intermediates and interacts with cell membrane lipids causing lipid peroxidation.

  • Dox-SL

  • (Other name for: doxorubicin hydrochloride liposome)

  • dronabinol

  • A synthetic form of delta-9-tetrahydrocannabinol, a psychoactive substance found in Cannabis sativa. Dronabinol acts directly on the appetite and vomiting control centers in the brain to stimulate appetite and prevent emesis.

  • Droxia

  • (Other name for: hydroxyurea)

  • DTIC-Dome

  • (Other name for: dacarbazine)

  • dutasteride

  • A synthetic 4-azasteroid compound. Dutasteride competitively and specifically binds to isoenzymes 1 and 2 of 5-alpha-reductase, forming stable enzyme complexes and inhibiting the conversion of testosterone to 5α-dihydrotestosterone (DHT); the reduction in DHT activity may mitigate or prevent enlargement of the prostate gland. The type 2 5-alpha-reductase isoenzyme is primarily active in the reproductive tissues, while the type 1 isoenzyme is also active in skin and the liver.
