Check for active clinical trials using this agent. (NCI Thesaurus)
valrubicin: A semisynthetic derivative of the antineoplastic anthracycline antibiotic doxorubicin. With a mechanism of action that appears to differ from doxorubicin, valrubicin is converted intracytoplasmically into N-trifluoroacetyladriamycin, which interacts with topoisomerase II, stabilizing the complex between the enzyme and DNA; consequently, DNA replication and repair and RNA and protein synthesis are inhibited and the cell cycle is arrested in the G2 phase. In addition, this agent accumulates in the cell cytoplasm where it inhibits protein kinase C (PKC). Valrubicin is less cardiotoxic than doxorubicin when administered systemically; applied topically, this agent shows excellent tissue penetration. Structurally, the trifluoro-acetyl moiety on the amino group of the glycoside and the valerate moiety appear to result in a lipophilicity that is greater than of doxorubicin, resulting in increased intracytoplasmic concentrations. Check for active clinical trials using this agent. (NCI Thesaurus)

Upon intra-arterial hepatic artery administration of vandetanib (VTB)-eluting radiopaque beads (VERBs) BTG-002814, the DEBs occlude the tumor blood vessels and deprive tumor cells of oxygen and nutrients, thereby causing hepatic arterial embolization and direct tumor cell death. The VERBs release vandetanib from the beads in a sustained manner. Vandetanib selectively inhibits the tyrosine kinase activity of both VEGFR and EGFR, thereby blocking both VEGF/VEGFR- and EGF/EGFR-stimulated signaling and inhibiting cell proliferation, migration and angiogenesis in VEGFR/EGFR-expressing hepatic tumor cells. The DEBs, controlled release microspherical devices, cause low systemic exposure and prevent systemic toxicity of vandetanib. DEBs also deliver high concentrations of vandetanib in the tumor for a controlled and extended period of time. Use of radiopaque DEBs allows for visualization of both the bead location and the degree of embolization upon imaging.

vecabrutinib: An orally available second-generation, reversible inhibitor of Bruton's tyrosine kinase (BTK; Bruton agammaglobulinemia tyrosine kinase), with potential antineoplastic activity. Upon administration, vecabrutinib non-covalently binds to and inhibits the activity of both wild-type and the C481S mutated form of BTK, a resistance mutation in the BTK active site in which cysteine is substituted for serine at residue 481. This prevents the activation of the B-cell antigen receptor (BCR) signaling pathway and BTK-mediated activation of downstream survival pathways. This leads to an inhibition of the growth of malignant B-cells that overexpress BTK. Compared to other BTK inhibitors, vecabrutinib does not require interaction with the BTK C481 site and inhibits the proliferation of cells harboring the BTK C481S mutation. Other irreversible BTK inhibitors covalently bind to the C481 site to inhibit BTK’s activity; the C481S mutation prevents that binding.

vepoloxamer: A purified form of the non-ionic polyoxypropylene-based copolymer poloxamer 188 comprised of a hydrophobic core with hydrophilic side chains, with cytoprotective, hemorrheologic, anti-inflammatory, anti-thrombotic and fibrinolytic activities. Although the exact mechanism of action is not fully elucidated, upon intravenous administration, the hydrophobic polyoxypropylene core of vepoloxamer reversibly adheres to hydrophobic sites of damaged cell membranes, thereby fully covering the damaged sites. This prevents the attachment of other hydrophobic molecules, cell leakage of contents, such as ions, and restores the integrity of the damaged cell. Binding of vepoloxamer to damaged cells in the blood vessel walls prevents cell aggregation and improves blood flow. By occupying damaged sites, this agent also prevents inflammatory processes, inhibits thrombosis, and induces fibrinolysis. As the hydrophobic region of the lipid cell membrane is not exposed in healthy cells, vepoloxamer does not adhere to healthy cells. Check for active clinical trialsusing this agent. (NCI Thesaurus)

Votrient: (Other name for: pazopanib hydrochloride)
VSL#3: (Other name for: live freeze-dried lactic acid bacteria probiotic)
VSV-hIFNbeta-NIS: A recombinant, replication competent form of the oncolytic RNA virus vesicular stomatitis virus (VSV), based on the Indiana strain of VSV, that is genetically engineered to express the genes for the human cytokine interferon beta (IFNbeta) and the human thyroidal sodium-iodide symporter (NIS), with potential oncolytic and imaging activities. Upon intravenous administration, VSV-hIFNbeta-NIS is preferentially taken up by tumor cells, resulting in tumor cell infection, viral replication and a direct virus-mediated cytolytic effect against the infected tumor cells. IFN-mediated signaling is defective in tumor cells and tumor cells are unable to exert an anti-viral response against VSV. As normal, healthy cells secrete and respond normally to IFNbeta and are able to activate IFN-mediated anti-viral pathways, the expressed IFNbeta from the VSV-infected tumor cells helps protect normal cells from VSV infection. Upon subsequent administration of certain isotope-containing imaging agents, NIS expression by the infected tumor cells allows visualization and tracking of VSV biodistribution, and analysis and quantification of VSV-infected tumor cells by positron emission tomography (PET). Also, upon subsequent administration of the radioisotope iodine I 131 (I131), I131 can be taken up by NIS and allows for a cytotoxic dose of radiation to accumulate in the NIS-expressing VSV-infected tumor cells, which also leads to tumor cell death.
