ranolazine
An orally available, piperazine derivative with anti-anginal and potential antineoplastic activities. Ranolazine’s mechanism of action for its anti-ischemic effects has yet to be fully elucidated but may involve the alteration of the trans-cellular late sodium current in the ischemic myocyte. By preventing the rise of intracellular sodium levels, ranolazine may affect the transport activity of sodium-dependent calcium channels and prevent the calcium overload during myocardial ischemia, thereby preventing cellular injury. Ranolazine’s potential antineoplastic effect may depend on its inhibitory effect on fatty acid oxidation, which may sensitize tumor cells to apoptosis and decrease tumor cell proliferation; fatty acid oxidation provides energy and promotes tumor cell proliferation and survival.

A recombinant fusion protein composed of the full-length extracellular domain (soluble) of human receptor tyrosine kinase ephrin type-B receptor 4 (sEphB4) and fused, at its C-terminus, to full-length human serum albumin (HSA), with potential antineoplastic and anti-angiogenic activities. sEphB4-HSA functions as a decoy receptor for the membrane-bound ligand Ephrin-B2 (Efnb2) and interferes with the binding of Efnb2 to its native receptors, including EphB4 and EphA3. This may result in a reduction of angiogenesis and a reduction in cell growth of Efnb2 and/or EphB4 over-expressing tumor cells.

Due to the heterologous HRV2 IRES in this recombinant virus, PVS-RIPO only propagates in susceptible, nonneuronal cells (e.g., GBM).
recombinant oxytocin
A synthetic cyclic peptide form of the naturally occurring posterior pituitary hormone oxytocin. Oxytocin binds to oxytocin receptors in the uterine myometrium, which triggers the G-protein coupled receptor signal transduction cascade that causes increased intracellular calcium concentrations. Increased calcium concentration levels activate myosin light chain kinase which, in turn, induces the formation of the contractile protein actomyosin. This stimulates uterine smooth muscle contractions. This agent also stimulates smooth muscles in the mammary glands, thereby causing lactation. Check for active clinical trials using this agent.

recombinant parathyroid hormone
A recombinant therapeutic agent that is identical or similar to an 84-amino-acid polypeptide produced by the parathryoid gland which functions to maintain a constant concentration of calcium ions (Ca2+) in the extracellular fluid. In target tissues, parathyroid hormone (PTH) binds to and activates the parathryorid hormone receptor (PTHR), a cell surface G protein-coupled receptor; there are two types of receptors, parathyroid hormone receptor 1 (PTH1R) found in bone and the kidney and parathyroid hormone receptor 2 (PTH2R) found primarily in the central nervous system (CNS), pancreas, testis, and placenta. Activation of PTHRs results in the activation of adenylyl cyclase and phospholipase C in target tissue cells, which, depending upon the specific target tissue, results in the enhancement of intestinal Ca2+ absorption, mobilization of bone Ca2+, and renal Ca2+ reabsorption.

recombinant vesicular stomatitis virus-expressing interferon-beta
A recombinant, replicating oncolytic vesicular stomatitis virus (VSV) carrying the human interferon-beta (IFN-b) gene, with potential immunomodulating and antineoplastic activities. Upon intratumoral administration, recombinant VSV expressing IFN-b replicates in the tumor environment specifically, partially due to defective innate antiviral host defense mechanisms in tumor cells, involving type I IFNs, and exerts its cytolytic activity towards the tumor cells.

retinoid 9cUAB30
A synthetic analogue of 9-cis retinoic acid with potential antineoplastic and chemopreventive activities. Retinoid 9cUAB30 binds to and activates retinoid X receptor (RXR) homodimers and/or and retinoic acid receptor (RAR)/RXR heterodimers, which may result in the dissociation of corepressor protein and the recruitment of coactivator protein, followed by transcription of downstream target genes into mRNAs and protein translation. Gene transcription regulated by these transcription factors may result in inhibition of cell proliferation, induction of cell differentiation, and apoptosis of both normal cells and tumor cells.

retinoid X receptor agonist IRX4204
A second generation rexinoid and agonist of retinoid X receptor (RXR), with potential antineoplastic, neuroprotective, immunoregulatory, and disease-modifying activities. Upon administration, IRX4204 specifically binds to and activates RXRs, thereby activating RXR-mediated signaling pathways and inducing changes in gene expression that lead to cell differentiation. In responsive cancer cells, IRX4204 induces cell differentiation, decreases cell proliferation, and induces apoptosis, which leads to cancer regression. IRX4204 enhances the differentiation of CD4-positive T lymphocytes into inducible regulatory T cells (iTreg) and suppresses the development of inflammatory T helper 17 (Th17) cells. In addition, IRX4204 is able to cross the blood-brain barrier (BBB) and induces the differentiation of oligodendrocyte precursor cells (OPCs) into oligodendrocytes, promotes repair of myelin, and enhances the survival of dopaminergic neurons.
retinol
The fat soluble vitamin retinol. Vitamin A binds to and activates retinoid receptors (RARs), thereby inducing cell differentiation and apoptosis of some cancer cell types and inhibiting carcinogenesis. Vitamin A plays an essential role in many physiologic processes, including proper functioning of the retina, growth and differentiation of target tissues, proper functioning of the reproductive organs, and modulation of immune function. Check for active clinical trials using this agent. (NCI Thesaurus)
retinyl acetate
A naturally-occurring fatty acid ester form of retinol (vitamin A) with potential antineoplastic and chemopreventive activities. Retinyl acetate binds to and activates retinoid receptors, inducing cell differentiation and decreasing cell proliferation. This agent also inhibits carcinogen-induced neoplastic transformation in some cancer cell types and exhibits immunomodulatory properties. Check for active clinical trials using this agent.

retrovector encoding mutant anti-cyclin G1
A replication-incompetent, pathotropic, tumor matrix (collagen)-targeted, retroviral vector encoding an N-terminal deletion mutant form of the cyclin G1 gene with potential antineoplastic activity. Under the control of a hybrid long-terminal repeat/cytomegalovirus (CMV) promoter, retrovector encoding mutant anti-cyclin G expresses the mutant cyclin G1 construct, resulting in disruption of tumor cell cyclin G1 activity and decreased cellular proliferation and angiogenesis. This agent preferentially targets collagen of the tumor matrix because of the incorporation of the collagen-binding domain of von Willebrand factor (vWF) on the retrovector surface. Exploiting the collagen-targeting mechanism of vWF permits delivery of the retrovector to tumor sites where angiogenesis and collagen matrix exposure occur. Check for active clinical trials using this agent. (NCI Thesaurus)
