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.

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. Check for active clinical trials using this agent. (NCI Thesaurus)

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. Check for active clinical trials using this agent. (NCI Thesaurus)

bendamustine-containing nanoparticle-based formulation RXDX-107

A nanoparticle-based formulation containing the alkyl ester of bendamustine, a bifunctional mechlorethamine derivative, encapsulated in human serum albumin (HSA), with potential alkylating and antineoplastic activities. Upon administration of the alkyl ester bendamustine-containing nanoparticle formulation RXDX-107, the nanoparticle formulation permits high concentrations of the alkyl ester of bendamustine be localized at the tumor site. The modified bendamustine alkylates and crosslinks macromolecules, resulting in DNA, RNA and protein synthesis inhibition, and, subsequently, apoptosis. Check for active clinical trials using this agent. (NCI Thesaurus)

bendamustine-vorinostat fusion molecule EDO-S101

An alkylating histone-deacetylase inhibitor (HDACi) fusion molecule composed of the alkylating agent bendamustine fused to the pan-HDACi vorinostat, with potential bi-functional antineoplastic activity. Upon administration of the bendamustine-vorinostat fusion molecule EDO-S101, the vorinostat moiety targets and binds to HDACs. This leads to an accumulation of highly acetylated histones, which results in an induction of chromatin remodeling, a modulation of gene expression, an inhibition of tumor cell division and the induction of tumor cell apoptosis. The bendamustine moiety binds to, alkylates and crosslinks macromolecules, inhibiting DNA, RNA and protein synthesis, which also results in tumor cell apoptosis. Thus, EDO-S101 shows superior efficacy compared to the activity of either agent alone. In addition, the inhibition of HDAC6 activity by EDO-S101 induces the activation of inositol-requiring enzyme 1 (IRE-1), the key regulatory protein for the unfolded protein response (UPR). Induction of the UPR increases the sensitivity of certain cancer cell types to certain chemotherapeutic agents, such as proteasome inhibitors. Therefore, EDO-S101 may work synergistically with proteasome inhibitors. HDACs, enzymes that deacetylate chromatin histone proteins, are overexpressed in various cancers and play a key role in proliferation and resistance of tumor cells.

The activation of b-lap also causes hyperactivation of poly (ADP-ribose) polymerase-1 (PARP-1), an enzyme that facilitates DNA repair, accompanied by rapid depletion of NAD+/ATP nucleotide levels. As a result, a caspase-independent and endoplasmic reticulum (ER) stress-induced mu-calpain-mediated cell death occurs in NQO1-overexpressing tumor cells. In addition, b-lap induces expression of the checkpoints activator E2F transcription factor 1 (E2F1) and thereby activates the E2F1-mediated checkpoint pathway that directly triggers apoptosis. As ARQ 761 is soluble and requires less solvent, this formulation may cause less hemolytic anemia associated with administration of the synthetic b-lap ARQ 501.

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.

Botox cosmetic

(Other name for: botulinum toxin type A)

botulinum toxin type A

An injectable formulation of a neurotoxin derived through the fermentation of the Hall strain of Clostridium botulinum type A with neuromuscular transmission inhibitory and analgesic activities. Upon injection into the affected muscle, the heavy chain portion of onabotulinumtoxinA binds to the cell membrane of the motor nerve and is internalized via endocytosis.

BP-Cx1-platinum complex BP-C1

A combination agent composed of the benzo-poly-carbonic-acid polymer BP-Cx1 chelated to platinum with potential antineoplastic activity. Upon intramuscular injection, the polymer moiety of BP-Cx1-Platinum Complex BP-C1 (BP-C1) alters the permeability of the cell membranes, which allows for increased penetration of platinum into tumor cells. In turn, platinum binds to nucleophilic groups such as GC-rich sites in DNA and induces intrastrand and interstrand DNA cross-links, as well as DNA-protein cross-links. These cross-links result in apoptosis and cell growth inhibition. In addition, the BP-Cx1 ligand is able to stimulate the innate immune system and upregulates a variety of cytokines including interferon, tumor necrosis factor-alpha (TNF-alpha), granulocyte macrophage-colony stimulating factor (GM-CSF), and various interleukins (ILs) such as IL-6 and IL-25.

B-Raf/VEGFR-2 inhibitor RAF265 binds and inhibits Raf kinases, which may result in a reduction of tumor cell growth and proliferation, and tumor cell death. In addition, this agent inhibits vascular endothelial growth factor receptor type 2 (VEGFR-2), thereby disrupting tumor angiogenesis. Raf kinases are critical enzymes in the Ras/Raf/MEK/ERK signaling pathway and are frequently upregulated in neoplasms. Check for active clinical trials using this agent. (NCI Thesaurus)

BRAFV600/PI3K inhibitor ASN003

A selective inhibitor of mutated forms of B-RAF kinase at amino acid position 600 (BRAFV600), including BRAFV600E, the alpha, delta and, to a lesser extent, beta isoforms of phosphatidylinositide 3-kinase (PI3K), including mutated forms of PI3KCA, which encodes the p110-alpha catalytic subunit of the class I PI3K, and the phosphatase and tensin homologs (PTEN) with loss-of-function mutation, with potential antineoplastic activity. Upon administration of ASN003, this agent selectively targets, binds to and inhibits the activity of BRAFV600 mutants as well as mutated isoforms of PI3K. This inhibits signaling through B-RAF- and PI3K/mechanistic target of rapamycin (mTOR)-mediated pathways and inhibits cellular proliferation in tumor cells with BRAFV600 mutations, those expressing PI3K and/or those driven by PTEN. Dysregulation of the B-RAF- and PI3K-mediated pathways is frequently seen in a variety of tumors and results in increased tumor cell growth and survival. Dual targeting of both pathways may increase efficacy and anti-tumor potential compared to the targeting of just one pathway by a selective B-RAF inhibitor or selective PI3K pathway inhibitor alone.

brain tumor initiating cell vaccine

A cell-based cancer vaccine comprised of brain tumor initiating cells (BTICs), with potential immunostimulating and antineoplastic activity. BITCs are from the glioblastoma multiforme (GBM) cell line GBM-6 and contain glioma stem-like cell-associated antigens. Upon administration, the BITC vaccine may stimulate a specific anti-tumoral cytotoxic T –lymphocyte (CTL) response against brain tumor cancer cells and brain tumor stem like cells, resulting in tumor cell lysis. BITC have unique antigenicity and have the ability to self-renew; vaccination against BITC antigens may kill these cells and may prevent tumor recurrences.

Brakiva

(Other name for: liposomal topotecan hydrochloride)

branched chain amino acid supplement

A nutritional supplement containing essential branched-chain amino acids (BCAAs), including leucine, isoleucine and valine, with potential anti-cachectic, antiangiogenic, hepatocellular carcinoma (HCC)-inhibiting and hepatoprotective activities. Upon oral administration, BCAAs inhibit the expression of both hypoxia-inducible factor 1-alpha subunit (HIF-1a) and vascular endothelial growth factor (VEGF), which prevents VEGF-mediated angiogenesis in HCC cells. In addition, BCAAs inhibit proliferation and induce apoptosis of HCC cells by both suppressing the expression of insulin-like growth factor (IGF), and inhibiting the phosphatidylinositol 3-kinase (PI3K)/Akt/mammalian target of rapamycin (mTOR) pathway. BCAAs also correct the plasma amino acid imbalance and promote protein metabolism, including the synthesis of albumin and glycogen. They reduce oxidative stress by inducing the activation of genes involved in antioxidant defenses, which prevent the production of reactive oxygen species (ROS). BCAAs also strengthen the immune system by increasing hepatic lymphocytes and stimulating natural killer (NK) cell activity. This supplement is able to improve insulin resistance and promote ammonia detoxification through increased glutamine (Gln) production. Check for active clinical trials using this agent.

Brassica vegetable

A vegetable belonging to the Brassica genus of plants in the mustard family with potential chemopreventive activity. Brassica vegetables, including broccoli, cabbage, kale, Brussel sprouts, turnip and cauliflower, contain a significant amount of glucosinolates. Glucosinolate metabolites, such as sulforaphane and indole-3-carbinol, act as antioxidants and may stimulate endogenous phase II detoxifying enzymes, including glutathione S-transferase and quinone reductase. These biotransformation enzymes play major roles in the detoxification of carcinogenic agents. Check for active clinical trials using this agent. (NCI Thesaurus)

BRD4 inhibitor PLX2853

An orally bioavailable inhibitor of the bromodomain-containing protein 4 (BRD4), with potential antineoplastic activity. Upon oral administration, the BRD4 inhibitor PLX2853 binds to the acetylated lysine recognition motifs in the bromodomains of the BRD4 protein, thereby preventing the binding of BRD4 to acetylated lysines on histones. This disrupts chromatin remodeling and dyregulates gene expression. This may lead to the downregulation of the expression of certain growth-promoting genes, which may induce apoptosis and inhibit the proliferation of BRD4-overexpressing tumor cells. BRD4, a member of the human bromodomain and extra-terminal (BET) family of proteins, is a transcriptional regulator that is overexpressed in certain tumor cells and plays an important role in cellular proliferation.

BRD4 inhibitor PLX51107

An inhibitor of the bromodomain-containing protein 4 (BRD4), with potential antineoplastic activity. Upon administration, the BRD4 inhibitor PLX51107 binds to the acetylated lysine recognition motifs in the bromodomains of the BRD4 protein, thereby preventing the binding of BRD4 to acetylated lysines on histones. This disrupts chromatin remodeling and gene expression. Prevention of the expression of certain growth-promoting genes may lead to an induction of apoptosis and an inhibition of proliferation in BRD4-overexpressing tumor cells. BRD4, a member of the human bromodomain and extra-terminal (BET) family of proteins, is a transcriptional regulator that is overexpressed in certain tumor cells and plays an important role in cellular proliferation.
