G207
A neuroattenuated, replication-competent, recombinant herpes simplex virus-1 (HSV-1) with potential oncolytic activity. Upon intracerebral administration, oncolytic HSV-1 G207 preferentially replicates within glioma cells, which may elicit tumor-specific systemic immune and cytotoxic T lymphocyte (CTL) responses in addition to direct cytopathic effects. Derived from wild-type HSV-1 strain F, this agent has been neuroattenuated by deletions in both copies of the gamma34.5 gene, the major determinant of HSV neurovirulence. In addition, the HSV-1 gene UL39, encoding the viral ribonucleotide reductase large subunit infected cell protein 6 (ICP6), has been inactivated through the insertion of the Escherichia coli lacZ gene. By inactivating UL39, viral ribonucleotide reductase activity is disrupted, resulting in the inhibition of nucleotide metabolism and viral DNA synthesis in nondividing cells but not in dividing cells.

gallium maltolate
An orally bioavailable form of the element gallium (Ga) composed of a trivalent gallium cation (Ga3+) coordinated to three maltolate ligands, with anti-inflammatory, anti-proliferative, antineoplastic, analgesic, antiresorptive and antibacterial activities. Upon administration of gallium maltolate, Ga3+, which is structurally similar to the ferric ion (Fe3+), competes with and replaces Fe3+ in many vital Fe 3+-mediated biological reactions.. Unlike Fe3+, Ga3+ cannot be reduced, cannot participate in redox reactions and cannot mimic Fe3+ functions. In rapidly proliferating cells, such as cancer cells, high amounts of iron are needed for DNA synthesis. The incorporation of Ga3+ inactivates the Fe3+-dependent enzyme ribonucleotide reductase (RR), an enzyme essential for DNA synthesis, leading to an inhibition of DNA synthesis and induction of cell death in rapidly proliferating cells. Gallium similarly reduces bacterial cell growth. In addition, Ga3+ is able to suppress inflammation through the down-regulation of pro-inflammatory cells and the inhibition of pro-inflammatory cytokine secretion. Gallium also exerts analgesic effects due to the inhibition of Fe3+-dependent enzymes involved in inflammation and may interfere with the activity of certain metalloproteinases and neuropeptides that are implicated in pain.

gemcitabine 5'-elaidic acid ester
A lipophilic, unsaturated fatty acid ester derivative of gemcitabine (dFdC), an antimetabolite deoxynucleoside analogue, with potential antineoplastic activity. Upon hydrolysis intracellularly by esterases, the prodrug gemcitabine is converted into the active metabolites difluorodeoxycytidine di- and tri-phosphate (dFdCDP and dFdCTP) by deoxycytidine kinase. dFdCDP inhibits ribonucleotide reductase, thereby decreasing the deoxynucleotide pool available for DNA synthesis; dFdCTP is incorporated into DNA, resulting in DNA strand termination and apoptosis. Due to its lipophilicity, gemcitabine 5'-elaidic acid ester exhibits an increased cellular uptake and accumulation, resulting in an increased conversion to active metabolites, compared to gemcitabine. In addition, this formulation of gemcitabine may be less susceptible to deamination and deactivation by deoxycytidine deaminase. Check for active clinical trials using this agent. (NCI Thesaurus)

Further, dFdCDP inhibits ribonucleotide reductase and reduces the deoxynucleotide pool available for DNA synthesis. Compared to gemcitabine alone, the emulsion allows for increased oral bioavailability and decreases its susceptibility to deamination and deactivation by cytidine deaminase. Check for active clinical trials using this agent. (NCI Thesaurus)
gemcitabine prodrug LY2334737
An orally available valproic acid ester of gemcitabine, a broad-spectrum antimetabolite with antineoplastic activity. Upon administration, gemcitabine prodrug LY2334737 is hydrolyzed by carboxylesterase 2 (CES2) and releases gemcitabine systemically over a period of time consistent with formation rate-limited kinetics. In turn, gemcitabine is converted into the active metabolites difluorodeoxycytidine diphosphate and triphosphate (dFdCDP and dFdCTP) by deoxycytidine kinase. dFdCDP inhibits ribonucleotide reductase, thereby decreasing the deoxynucleotide pool available for DNA replication; dFdCTP is incorporated into DNA, resulting in premature termination of DNA replication and eventually the induction of apoptosis. Compared to gemcitabine, this prodrug is able to avoid hydrolysis in enterocytes and the portal circulation thus avoiding first pass metabolism and increasing systemic gemcitabine availability. In addition, the slow release of gemcitabine may enhance efficacy while lowering toxicity.

genetically engineered HSV-1 expressing IL-12
A genetically engineered, replication selective, infected cell protein (ICP) 34.5 gene-deleted, oncolytic human simplex virus type 1 (HSV-1) expressing the human immunostimulating cytokine interleukin-12 (IL-12), with potential antineoplastic activity. Upon intratumoral administration of HSV-1 expressing IL-12, the IL-12-expressing HSV-1 preferentially infects and replicates in tumor cells of neuronal origin causing viral-mediated tumor cell lysis. The released virus particles, in turn, infect and replicate in neighboring tumor cells. In addition, the IL-12-expressing HSV-1 promotes the secretion of IL-12 by the tumor cells. IL-12 promotes the activation of natural killer cells, which induces both the secretion of interferon-gamma and a cytotoxic T-lymphocyte (CTL) response against the tumor cells. This results in both immune-mediated tumor cell death and further inhibition of tumor cell proliferation. Deletion of the gene encoding for ICP34.5 imparts tumor selectivity by preventing replication in healthy cells. Check for active clinical trials using this agent. (NCI Thesaurus)

glyburide
A sulfonamide urea derivative with antihyperglycemic activity that can potentially be used to decrease cerebral edema. Upon administration, glyburide binds to and blocks the sulfonylurea receptor type 1 (SUR1) subunit of the ATP-sensitive inwardly-rectifying potassium (K(ATP)) channels on the membranes of pancreatic beta cells. This prevents the inward current flow of positively charged potassium (K+) ions into the cell, and induces a calcium ion (Ca2+) influx through voltage-sensitive calcium channels, which triggers exocytosis of insulin-containing granules. In addition, glyburide also inhibits the SUR1-regulated nonselective cation (NC) Ca-ATP channel, melastatin 4 (transient receptor potential cation channel subfamily M member 4; (TRPM4)), thereby preventing capillary failure and brain swelling. SUR1-TRPM4 channels are formed by co-assembly of SUR1 with TRPM4 in neurons, astrocytes, and capillary endothelium during cerebral ischemia. Upon ischemia-induced ATP depletion, channels open which results in sodium influx, cytotoxic edema formation, capillary fragmentation and necrotic cell death. SUR1-TRPM4 is not expressed in normal, uninjured tissues. Check for active clinical trials using this agent.

(Other name for: miglitol)
GlyT2/5HT2a antagonist VVZ-149
An antagonist of both glycine transporter type 2 (GlyT2) and serotonin receptor 2A (5HT2A), with potential anti-nociceptive activity. Upon administration, GlyT2/5HT2A antagonist VVZ-149 binds to and blocks both GlyT2 and 5HT2A. Blockage of GlyT2 prevents the re-uptake of the inhibitory neurotransmitter glycine in the synaptic cleft, thereby potentiating glycine-mediated inhibitory signaling, and inhibiting the firing of neurons, which suppresses the transmission of pain signals to the brain and induces analgesia. Blockage of 5HT2A prevents both the binding of its ligand serotonin and 5HT/5HT2A-mediated signaling. This also suppresses pain signaling and induces analgesia. GlyT2 and 5HT2A play key roles in the induction and transmission of pain signals. GlyT2, a glycine plasma membrane transporter, modulates glycine-mediated inhibition of synaptic transmission in the spinal cord and mediates pain signal transmission to the brain; inhibition of GlyT2 potentiates glycinergic mediated pain signaling.

A recombinant, oncolytic serotype 5/3 capsid-modified adenovirus encoding the immunostimulatory cytokine granulocyte-macrophage colony-stimulating factor (GM-CSF) with potential antineoplastic activity. Upon administration, the oncolytic adenovirus selectively infects and replicates in tumor cells, which may result in tumor cell lysis. Synergistically, GM-CSF (sargramostim) expressed by the oncolytic adenovirus enhances antigen presentation, promotes natural killer (NK) cell-mediated killing and causes a cytotoxic T cell (CTL) response against tumor cells harboring the oncolytic adenovirus, resulting in an immune-mediated tumor cell death. CGTG-102 is designed to replicate only in cells with defects in the p16/Rb/E2F pathway, attributed to a mutation common in many solid tumors. Replacement of the Ad5 capsid protein knob with a knob domain from serotype 3 causes higher transduction in cancer cells as compared to normal cells.

GM-K562 cell vaccine
A cell-based vaccine comprised of K562 cells transfected with the granulocyte macrophage-colony stimulating factor (GM-CSF) gene with potential immunopotentiating properties. Vaccination with GM-K562 cells may stimulate the host immune system to produce an antitumoral T-lymphocyte response, thereby inhibiting tumor growth. K562 cells are derived from the human erythroleukemia cell line K562. GM-CSF (also known as sagramostim) expressed by vaccine cells binds to specific cell surface receptors, modulating the proliferation and differentiation of a variety of hematopoietic progenitor cells with some specificity towards stimulation of leukocyte production. GM-CSF also promotes antigen presentation, up-regulates antibody-dependent cellular cytotoxicity (ADCC), and increases interleukin-2-mediated lymphokine-activated killer cell function; it may also augment host antitumoral immunity.

gold sodium thiomalate
The sodium salt of gold thiomalic acid, an organogold compound with antirheumatic and potential antineoplastic activities. Gold sodium thiomalate (GST) appears to inhibit the activity of atypical protein kinase C iota (PKCiota) by forming a cysteinyl-aurothiomalate adduct with the cysteine residue Cys-69 within the PB1 binding domain of PKCiota. This prevents the binding of Par6 (Partitioning defective protein 6) to PKCiota, thereby inhibiting PKCiota-mediated oncogenic signaling, which may result in the inhibition of tumor cell proliferation, the promotion of tumor cell differentiation, and the induction of tumor cell apoptosis. Atypical PKCiota, a serine/threonine kinase overexpressed in numerous cancer cell types, plays an important role in cancer proliferation, invasion, and survival; Par6 is a scaffold protein that facilitates atypical PKC-mediated phosphorylation of cytoplasmic proteins involved in epithelial and neuronal cell polarization.

gonadotrophin releasing hormone analogue
A synthetic analog of the endogenous hormone gonadotropin-releasing hormone (GnRH), with potential antineoplastic activity. Upon administration, GnRH analog mimics endogenous GnRH and strongly binds to and activates pituitary GnRH receptors, which stimulates the synthesis and secretion of the gonadotropic hormones, follicle stimulating hormone (FSH) and luteinizing hormone (LH). Continuous, prolonged activation by the GnRH analog results in pituitary GnRH receptor desensitization and receptor downregulation. This causes inhibition of pituitary gonadotropin secretion of LH and FSH. In males, the inhibition of LH secretion prevents the production and release of testosterone from Leydig cells in the testes and causes a significant decline in testosterone production that is near the levels seen after castration. This may inhibit androgen receptor-positive tumor progression. In females, this results in a decrease in estradiol production. GnRH, also called luteinizing hormone-releasing hormone (LH-RH), is normally synthesized in and secreted by the hypothalamus. Synthetic analogs of GnRH have a stronger receptor binding affinity than the endogenous form. Check for active clinical trials using this agent. (NCI Thesaurus)

gp96-secreting allogeneic bladder cancer cell vaccine HS-410
An allogeneic urothelial bladder cancer cell vaccine expressing a recombinant secretory form of the immunoadjuvant heat shock protein gp96 fused with an immunoglobulin Fc domain (gp96-Ig) protein, with potential antineoplastic activity. Upon administration of the gp96-Ig-secreting allogeneic bladder cancer cell vaccine HS-410, the live, irradiated tumor cells continuously secrete gp96-Ig along with its chaperoned tumor associated antigens (TAAs). This enhances antigen cross presentation to cytotoxic T-lymphocytes (CTLs) and, upon expansion, leads to the induction of a potent CTL response against the TAAs on the endogenous bladder cancer cells. This vaccine also induces a memory T cell response that could fight recurring cancer cells. gp96-Ig is constructed by replacing the KDEL endoplasmic reticulum (ER) retention sequence of gp96 with the Fc portion of the IgG1 protein.
