B16alphaGal melanoma vaccine

A whole cell melanoma cancer vaccine with potential immunostimulating and antineoplastic activities. B16alphaGal melanoma vaccine contains three types of human melanoma cell lines that are genetically engineered to express the alpha(1,3)-galactosyl (alphaGal) epitope on cell surfaces. The agent stimulates a hyperacute rejection of whole melanoma cancer cells expressing alphaGal epitopes, initiated by opsonization by anti-alphaGal antibodies and followed by antibody-dependent cell-mediated cytotoxicity (ADCC) and cell lysis. This results in the stimulation of a broader cytotoxic T-lymphocyte response (CTL) directed against tumor antigens on melanoma cells that do not express alphaGal. AlphaGal is not normally expressed in humans because alpha(1,3)-galactosyltransferase (Alpha-GT), the enzyme that catalyzes the synthesis of alphaGal epitopes on glycoproteins and glycolipids, is not naturally present in humans and other primates.

B43-PAP immunotoxin

A mouse-derived anti-human CD19 monoclonal antibody linked to pokeweed (Phytolacca americana) antiviral protein (PAP) with antileukemic activity. The monoclonal antibody portion specifically binds to the CD19 antigen, a cell surface molecule normally expressed only by B lymphocytes and follicular dendritic cells and over-expressed in B-lineage lymphocytic leukemia cells. Following internalization, PAP, a plant hemitoxin and a ribosome-inactivating protein, is cleaved from the immunoconjugate and released into the cytoplasm where it enzymatically removes a single adenine base from a conserved, surface exposed loop sequence of rRNA leading to inhibition of protein synthesis and cell growth, but not necessarily cell death.

B7-DC cross-linking antibody rHIgM12B7

A recombinant form of the monoclonal IgM antibody M12 isolated from a Waldenstrom macroglobulinaemia patient (rHIgM12) with potential immunomodulating activity. B7-DC cross-linking antibody rHIgM12B7 binds and crosslinks the B7 co-stimulatory family member B7-DC (PD-L2) on dendritic cells (DCs), antigen presenting cells (APCs) that play a crucial role in the human immune response. This results in enhanced activation of DCs; enhanced antigen-presenting activity; and increased production of immunomodulatory cytokines (especially interleukin 12); and may potentiate a specific cytotoxic T lymphocyte (CTL) response against Waldenstrom macroglobulinaemia B cells.

bacitracin

A complex of cyclic polypeptide antibiotics, mainly bacitracin A, produced by spore-forming organisms belonging to the licheniformin group of the Bacillus subtilis with antibacterial activity. Bacitracin binds to C55-isoprenyl pyrophosphate, a biphosphate lipid transport molecule that carries the building blocks of the peptidoglycan bacterial cell wall. The binding interferes with the enzymatic dephosphorylation of the C55-isoprenyl pyrophosphate and prevents peptidoglycan synthesis, thereby inhibiting bacterial cell growth.

baclofen

A synthetic chlorophenyl-butanoic acid derivative with muscle relaxant activity. Baclofen acts as a gamma-aminobutyric acid (GABA) agonist specific for GABA-B receptors in the central nervous system (CNS). At spinal and supraspinal sites, this agent reduces excitatory transmission.

baclofen/amitriptyline/ketamine gel

A topical preparation of baclofen, amitriptyline, and ketamine compounded in a penetration-enhancing polaxamer-lecithin organogel (PLO) with potential antineuralgic activity. The gamma-aminobutyric acid (GABA) analogue baclofen appears to activate the inhibitory GABA(B) receptor, a G protein-coupled receptor, which may result in hyperpolarization of the neuronal cell membrane and inhibition of neurotransmitter release. Amitriptyline likely produces antineuralgic effects via modulation of multiple subtypes of glutamate (Glu) receptors, independent of its antidepressant actions. Ketamine displays complex pharmacologic actions including biogenic amine uptake inhibition, interaction with opioid receptors, and inhibition of N-methyl D-aspartate (NMDA) receptors. Stimulation of GABA(B) receptor activity, modulation of Glu receptor activity, and inhibition of NMDA receptor activity may be of benefit in managing neuropathic pain.

Bactrim

(Other name for: trimethoprim-sulfamethoxazole)

bafetinib

An orally bioavailable 2-phenylaminopyrimidine derivative with potential antineoplastic activity. Bafetinib specifically binds to and inhibits the Bcr/Abl fusion protein tyrosine kinase, an abnormal enzyme produced by Philadelphia chromosomal translocation associated with chronic myeloid leukemia (CML). This agent also inhibits the Src-family member Lyn tyrosine kinase, upregulated in imatinib-resistant CML cells and in a variety of solid cancer cell types. The inhibitory effect of bafetinib on these specific tyrosine kinases may decrease cellular proliferation and induce apoptosis in tumor cells that overexpress these kinases. CML patients may be refractory to imatinib, which sometimes results from point mutations occurring in the kinase domain of the Bcr/Abl fusion product. Due to its dual inhibitory activity, the use of bafetinib has been shown to overcome this particular drug resistance.

Bag Balm

(Other name for: 8-hydroxyquinoline sulfate ointment)

banoxantrone

A bioreductive, alkylaminoanthraquinone prodrug with antineoplastic activity. Under hypoxic conditions, often seen in solid tumors, banoxantrone (AQ4N) is converted and activated by cytochrome P450 enzymes, which are upregulated in certain tumors, to the cytotoxic DNA-binding agent AQ4. Banoxantrone intercalates into and crosslinks DNA, and inhibits topoisomerase II. This results in an inhibition of DNA replication and repair in tumor cells. Combined with conventional therapeutic agents, both oxygenic and hypoxic regions of tumors can be targeted.

Baraclude

(Other name for: entecavir)

bardoxolone

A synthetic triterpenoid compound with potential antineoplastic and anti-inflammatory activities. Bardoxolone blocks the synthesis of inducible nitric oxide synthase (iNOS) and inducible cyclooxygenase (COX-2), two enzymes involved in inflammation and carcinogenesis. This agent also inhibits the interleukin-1 (IL-1)-induced expression of the pro-inflammatory proteins matrix metalloproteinase-1 (MMP-1) and matrix metalloproteinase-13 (MMP-13) and the expression of Bcl-3; Bcl-3 is an IL-1-responsive gene that preferentially contributes to MMP-1 gene expression.

batabulin sodium

A synthetic pentafluorophenylsulfonamide with potential antineoplastic activity. Batabulin sodium covalently binds to and selectively modifies the beta 1, beta 2, beta 3, and beta 4 isotypes of beta tubulin at a conserved cysteine residue, resulting in disruption of microtubule polymerization, collapse of the cytoskeleton, an increase in chromosomal ploidy, cell cycle arrest, and tumor cell apoptosis.

bavituximab

An IgG3 monoclonal antibody directed against anionic phospholipids with potential antineoplastic activity. Chimeric anti-phosphotidylserine monoclonal antibody binds to anionic phospholipids in a beta 2-glycoprotein I-dependent manner, inhibiting tumor growth by stimulating antibody-dependent cellular cytotoxicity (ADCC) to tumor vessels.

BAY 56-3722

A water-soluble camptothecin derivative conjugated to a carbohydrate moiety exhibiting antineoplastic activity. BAY 56-3722 stabilizes the topoisomerase I-DNA covalent complex and forms an enzyme-drug-DNA ternary complex. As a consequence of the formation of this complex, both the initial cleavage reaction and religation steps are inhibited and subsequent collision of the replication fork with the cleaved strand of DNA results in inhibition of DNA replication, double strand DNA breakage and triggering of apoptosis. The peptide carbohydrate moiety of this agent stabilizes the lactone form of camptothecin in blood.

BayGam

(Other name for: therapeutic immune globulin)

BCG intravesical solution

A solution containing an attenuated, live culture preparation of the Bacillus Calmette Guerin (BCG) strain of Mycobacterium bovis with potential immunostimulating activity. Although the precise mechanism of action is unknown, upon intravesical administration, attenuated, live BCG bacteria in the solution come into direct contact with the bladder wall, inciting an antitumor granulomatous inflammatory reaction.

BCG vaccine

A vaccine containing bacillus Calmette-Guerin (BCG), an attenuated strain of Mycobacterium bovis, with non-specific immunoadjuvant and immunotherapeutic activities. Although the mechanism of its anti-tumor activity is unclear, immunization with BCG vaccine likely activates a Th1 cytokine response that includes the induction of interferon. Vaccination with BCG vaccine may be immunoprotective against infection with Mycobacterium tuberculosis.

bcr-abl (b2a2)-derived peptide vaccine

A peptide vaccine consisting of the bcr-abl b2a2 fusion oncoprotein, frequently expressed in chronic myelogenous leukemia (CML), with potential antineoplastic activity. Vaccination with the bcr-abl (b2a2)-derived peptide vaccine may stimulate the host immune system to mount a cytotoxic T lymphocyte (CTL) response against tumor cells that express the bcr-abl b2a2 fusion protein. Fusion genes in CML typically result from the fusion of either BCR exon b2 or BCR exon b3 to ABL exon a2, a 'b3a2' or a 'b2a2' fusion.

bcr-abl (b3a2)-derived peptide vaccine

A peptide vaccine consisting of the bcr-abl b3a2 fusion oncoprotein, frequently expressed in chronic myelogenous leukemia (CML), with potential antineoplastic activity. Vaccination with the bcr-abl (b3a2)-derived peptide vaccine may stimulate the host immune system to mount a cytotoxic T lymphocyte (CTL) response against tumor cells that express the bcr-abl b3a2 fusion protein. Fusion genes in CML typically result from the fusion of either BCR exon b2 or BCR exon b3 to ABL exon a2, a 'b3a2' or a 'b2a2' fusion.

bcr-abl p210-b3a2 breakpoint-derived multipeptide vaccine

A multipeptide vaccine consisting of five peptides derived from the bcr-abl p210-b3a2 breakpoint fusion protein with potential antineoplastic activity. Vaccination with bcr-abl p210-b3a2 breakpoint-derived multipeptide vaccine may stimulate the host immune system to mount a cytotoxic T lymphocyte (CTL) response against tumor cells that express the bcr-abl p210-b3a2 breakpoint fusion protein. In chronic myelogenous leukemia (CML), fusion genes typically result from the fusion of either bcr exon b2 or exon b3 to abl exon a2, resulting in either a b3a2 or a b2a2 gene fusion product.

Beclovent

(Other name for: beclomethasone dipropionate)

Beconase

(Other name for: beclomethasone dipropionate)

Beesix

(Other name for: pyridoxine hydrochloride)

belagenpumatucel-L

A transforming growth factor beta2 (TGF-beta2) antisense gene-modified allogeneic tumor cell vaccine with potential immunostimulatory and antineoplastic activities. Belagenpumatucel-L is prepared by transfecting allogeneic non-small cell lung cancer (NSCLC) cells with a plasmid containing a TGF-beta2 antisense transgene, expanding the cells, and then irradiating and freezing them. Upon administration, this agent may elicit a cytotoxic T lymphocyte (CTL) response against host NSCLC cells, resulting in decreased tumor cell proliferation; vaccine immunogenicity may be potentiated by suppression of tumor TGF-beta2 production by antisense RNA expressed by the vaccine plasmid TGF-beta2 antisense transgene. Elevated levels of TGF-beta2 are frequently linked to immunosuppression in cancer patients and may be inversely correlated with prognosis in patients with NSCLC.

belimumab

A fully human IgG1 monoclonal antibody directed against B-Lymphocyte stimulator protein (BlyS or TNFSF13B) with potential immunomodulating activity. Belimumab specifically recognizes and inhibits the biological activity of BlyS, thereby preventing the binding of BlyS to B-lymphocytes. This inhibits the maturation of B-lymphocytes and may induce apoptosis in B-lymphocytes. In addition, it may decrease B-lymphocyte proliferation and/or survival. BlyS, a member of TNF family supporting B-lymphocyte maturation and survival, has been implicated in the pathogenesis of autoimmune diseases and B-lymphocyte malignancies.

belinostat

A novel hydroxamic acid-type histone deacetylase (HDAC) inhibitor with antineoplastic activity. Belinostat targets HDAC enzymes, thereby inhibiting tumor cell proliferation, inducing apoptosis, promoting cellular differentiation, and inhibiting angiogenesis. This agent may sensitize drug-resistant tumor cells to other antineoplastic agents, possibly through a mechanism involving the down-regulation of thymidylate synthase.

belotecan hydrochloride

The hydrochloride salt of the semi-synthetic camptothecin analogue belotecan with potential antitumor activity. Belotecan binds to and inhibits the activity of topoisomerase I, stabilizing the cleavable complex of topoisomerase I-DNA, which inhibits the religation of single-stranded DNA breaks generated by topoisomerase I; lethal double-stranded DNA breaks occur when the topoisomerase I-DNA complex is encountered by the DNA replication machinery, DNA replication is disrupted, and the tumor cell undergoes apoptosis. Topoisomerase I is an enzyme that mediates reversible single-strand breaks in DNA during DNA replication.

bemiparin sodium

The sodium salt of bemiparin, a second generation, synthetic, low-molecular-weight heparin (LMWH) with anticoagulant activity. Derived, after depolymerisation and fractionation, from medical-grade porcine unfractionated heparin (UFH), bemiparin has an average molecular weight of 3,600 daltons and has a higher anti-factor Xa/anti-factor IIa ratio (8:1) than first-generation LMWHs. This anticoagulant binds to antithrombin III, thereby enhancing the inactivation of activated Factor X (Factor Xa) and, to a lesser extent, activated factor II (Factor IIa). Compared to unfractionated heparins, the use of bemiparin is associated with lower incidences of major bleeding, osteoporosis, and heparin-induced thrombocytopenia. Bemiparin also promotes a greater release of tissue factor pathway inhibitor than UFH or dalteparin.

Benadryl

(Other name for: diphenhydramine hydrochloride)

benazepril hydrochloride

The hydrochloride salt of benazepril, a carboxyl-containing angiotensin-converting enzyme (ACE) inhibitor with antihypertensive activity. As a prodrug, benazepril is metabolized to its active form benazeprilat. Benazeprilat competitively binds to and inhibits ACE, thereby blocking the conversion of angiotensin I to angiotensin II. This prevents the potent vasoconstrictive actions of angiotensin II, resulting in vasodilation. Benazeprilat also decreases angiotensin II-induced aldosterone secretion by the adrenal cortex, which leads to an increase in sodium excretion and subsequently increases water outflow.

bendamustine hydrochloride

The hydrochloride salt of bendamustine, a bifunctional mechlorethamine derivative with alkylator and antimetabolite activities. Bendamustine possesses three active moieties: an alkylating group; a benzimidazole ring, which may act as a purine analogue; and a butyric acid side chain. Although its exact mechanism of action is unknown, this agent appears to act primarily as an alkylator. Bendamustine metabolites alkylate and crosslink macromolecules, resulting in DNA, RNA and protein synthesis inhibition, and, subsequently, apoptosis. Bendamustine may differ from other alkylators in that it may be more potent in activating p53-dependent stress pathways and inducing apoptosis; it may induce mitotic catastrophe; and it may activate a base excision DNA repair pathway rather than an alkyltransferase DNA repair mechanism. Accordingly, this agent may be more efficacious and less susceptible to drug resistance than other alkylators.

Bendopa

(Other name for: levodopa)

Benefin

(Other name for: shark cartilage)

Benemid

Unlike other anthracycline derivatives, this agent crosses the blood-brain barrier (BBB).

beta carotene

A naturally-occurring retinol (vitamin A) precursor obtained from certain fruits and vegetables with potential antineoplastic and chemopreventive activities. As an anti-oxidant, beta carotene inhibits free-radical damage to DNA. This agent also induces cell differentiation and apoptosis of some tumor cell types, particularly in early stages of tumorigenesis, and enhances immune system activity by stimulating the release of natural killer cells, lymphocytes, and monocytes.

beta-glucan

A polysaccharide isolated from the cell walls of bacteria, plants, and fungi with immunostimulant and antineoplastic activities. In a solubilized form, beta-glucan binds to a lectin site within complement receptor 3 (CR3) on leukocytes, priming the receptor to trigger cytotoxic degranulation of leukocytes when leukocyte CR3 binds to complement 3 (iC3b)-coated tumors. Thus, the attachment of beta-glucan to CR3 of circulating leukocytes simulates leukocytes to kill iC3b-coated tumor cells in the same way as they kill iC3b-coated yeast.

beta-glucan MM-10-001

A powder formulation containing a triple helix beta-glucan, isolated from the cell walls of the shiitake mushroom (Lentinula edodes), with potential immunostimulating activity. The beta-glucan in beta-glucan MM-10-001 binds to a lectin site within the complement receptor 3 (CR3 or iC3b receptor) on leukocytes, priming the receptor to trigger cytotoxic degranulation of leukocytes when leukocyte CR3 binds to iC3b-opsonized tumor cells. iC3b is the proteolyticly inactive product of the complement cleavage fragment C3b.

beta-lapachone

A poorly soluble, ortho-naphthoquinone with potential antineoplastic and radiosensitizing activity. Beta-lapachone (b-lap) is bioactivated by NAD(P)H:quinone oxidoreductase-1 (NQO1), creating a futile oxidoreduction that generates high levels of superoxide. In turn, the highly reactive oxygen species (ROS) interact with DNA, thereby causing single-strand DNA breaks and calcium release from endoplasmic reticulum (ER) stores. Eventually, the extensive DNA damage causes hyperactivation of poly(ADP-ribose) polymerase-1 (PARP-1), an enzyme facilitating DNA repair, accompanied by rapid depletion of NAD+/ATP nucleotide levels. As a result, a caspase-independent and ER-stress induced mu-calpain-mediated cell death occurs in NQO1-overexpressing tumor cells. NQO1, a flavoprotein and two-electron oxidoreductase, is overexpressed in a variety of tumors.

beta-thioguanine deoxyriboside

A thiopurine nucleoside derivative with antineoplastic activity. After conversion to the triphosphate, beta-thioguanine deoxyriboside is incorporated into DNA, resulting in inhibition of DNA replication.

As a result, there is an overall reduction in chronic inflammation and autoimmune reactions.

Betaseron

(Other name for: recombinant interferon beta)

betulinic acid

A pentacyclic lupane-type triterpene derivative of betulin (isolated from the bark of Betula alba, the common white birch) with antiinflammatory, anti-HIV and antineoplastic activities. Betulinic acid induces apoptosis through induction of changes in mitochondrial membrane potential, production of reactive oxygen species, and opening of mitochondrial permeability transition pores, resulting in the release of mitochondrial apogenic factors, activation of caspases, and DNA fragmentation. Although originally thought to exhibit specific cytotoxicity against melanoma cells, this agent has been found to be cytotoxic against non-melanoma tumor cell types including neuroectodermal.and brain tumor cells.

bevacizumab

A recombinant humanized monoclonal antibody directed against the vascular endothelial growth factor (VEGF), a pro-angiogenic cytokine. Bevacizumab binds to VEGF and inhibits VEGF receptor binding, thereby preventing the growth and maintenance of tumor blood vessels.

BI 2536

A small molecule compound with potential antineoplastic activities. BI 2536 binds to and inhibits Polo-like kinase 1 (Plk1), resulting in mitotic arrest, disruption of cytokinesis, and apoptosis in susceptible tumor cell populations. Plk1, a serine/threonine-protein kinase, is a key regulator of multiple processes fundamental to mitosis and cell division.

bi-shRNA-furin/GMCSF-expressing autologous tumor cell vaccine

Autologous tumor cells transfected with a plasmid expressing recombinant human granulocyte macrophage-colony stimulating factor (rhGM-CSF) and bifunctional short hairpin RNA (bi-shRNA) against furin, with potential immunostimulatory and antineoplastic activities. Upon intradermal vaccination of bi-shRNA-furin/GM-CSF-expressing autologous tumor cell vaccine, expressed GM-CSF protein, a potent stimulator of the immune system, recruits immune effectors to the site of injection and promotes antigen presentation. The furin bifunctional shRNA blocks furin protein production. Decreased levels of furin lead to a reduction in the conversion of transforming growth factor (TGF) beta into TGF beta1 and beta2 protein isoforms. In turn, as part of the negative feedback mechanism, reduced furin protein levels inhibit TGFbeta1 and TGFbeta2 gene expression, thereby further decreasing TGF levels. As TGFs are potent immunosuppressive cytokines, reducing their levels may activate the immune system locally and this may eventually cause a cytotoxic T-lymphocyte (CTL) response against the tumor cells.

Biaxin

(Other name for: clarithromycin)

BIBX 1382

A pyrimido-pyrimidine with antitumor activity.

This bispecific monoclonal antibody brings CD19-expressing tumor B-cells and cytotoxic T lymphocytes (CTLs) and helper T lymphocytes (HTLs) together, which may result in the CTL- and HTL-mediated cell death of CD19-expressing B-lymphocytes.

blue citrus-based herbal capsule

An oral capsule formulation of a traditional Chinese herbal medicine with potential analgesic activity. In addition to other herbs, seeds and fruits, blue citrus-based herbal capsule contains the Chinese herb blue citrus (qing pi), which is produced from the dried immature green peel of the tangerine Citrus reticulata Blanco. Blue citrus contains large amounts of limonene, citral and synephrine, which may attribute to its analgesic activity. However, due to the complexity of its chemical components, the exact mechanism of action of this agent remains to be determined.

BMS-214662

A nonsedating benzodiazepine derivative with potential antineoplastic activity. Farnesyltransferase inhibitor BMS-214662 inhibits the enzyme farnesyltransferase and the post-translational farnesylation of number of proteins involved in signal transduction, which may result in the inhibition of Ras function and apoptosis in susceptible tumor cells. This agent may reverse the malignant phenotype of H-Ras-transformed cells and has been shown to be active against tumor cells with and without Ras mutations.

bone metastasis targeting peptide-11

A peptide that mimics naturally occurring interleukin-11 (IL-11) with interleukin receptor binding activity. Upon administration, bone metastasis targeting peptide-11 (BMTP-11) binds to interleukin-11 receptor alpha (IL-11Ra) BMTP-11. This agent might be used to deliver therapeutic agents specifically to IL-11Ra-expressing tumor cells while sparing normal cells. IL-11Ra is a cell surface receptor that may be overexpressed by osteosarcoma cells and by prostate cancer cells in prostate cancer bone metastases.

boronophenylalanine-fructose complex

A boronated phenylalanine complexed with fructose to increase its solubility. When exposed to neutron irradiation, boronophenylalanine absorbs neutrons and self-destructs releasing short-range alpha radiation and 'recoil' lithium in tumor cells, resulting in alpha radiation-induced tumor cell death. This highly selective, localized radiotargeting of tumor cells, known as boron neutron capture therapy (BNCT), spares adjacent normal tissues.
