GSK1059615 is a phosphoinositide 3-kinase (PI3K) inhibitor with potential antineoplastic activity. PI3K inhibitor GSK1059615 inhibits PI3K in the PI3K/AKT kinase signaling pathway, which may trigger the translocation of cytosolic Bax to the mitochondrial outer membrane and an increase in mitochondrial membrane permeability, followed by apoptosis. Bax is a member of the proapoptotic Bcl-2 family of proteins. PIK3, an enzyme often overexpressed in cancer cells, plays a crucial role in tumor cell regulation and survival. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus).

TH9402 is a dibrominated rhodamine derivative and potent photosensitizer and useful in photodynamic therapy. TH9402 eradicates multiple myeloma (MM) and BC cell lines, while sparing more than 50% of normal pluripotential blood stem cells from healthy volunteers. TH9402 offers an excellent potential as an ex vivo photodynamic purging agent for autologous transplantation in MM and BC treatment.

Methyl-5-aminolevulinate hydrochloride cream is a topical cream formulation containing the hydrochloride salt of methyl-5-aminolevulinate, a lipophilic methyl ester of 5-aminolevulinic acid, with photosensitizer prodrug activity. Upon topical administration, methyl-5-aminolevulinate in the cream is selectively absorbed by tumor cells where it is converted to the photosensitizer protoporphyrin IX (PpIX). Upon photoirradiation, PpIX is activated and transfers energy to oxygen, generating singlet oxygen and superoxide and hydroxyl radicals, which may result in free-radical-mediated DNA damage and cell death.

Apoptone, also known as HE3235, is an orally bioavailable adrenal steroid analogue with potential antineoplastic activity. Androstane steroid HE3235 appears to bind the androgen receptor (AR), down-regulating anti-apoptotic genes, such as Bcl-2, while increasing the expression of pro-apoptotic genes, such as caspases. In vitro and in vivo studies indicate that this agent inhibits androstenediol-dependent LNCaP cell tumor growth. In addition, HE3235 may potentiate chemotherapeutic agents by down-regulating ABCG2, the gene encoding the multi-drug resistant (MDR) protein MDR2.

Eflornithine, also known as Difluoromethylornithine, is a difluoromethylated ornithine compound with antineoplastic activity. Eflornithine irreversibly inhibits ornithine decarboxylase, an enzyme required for polyamine biosynthesis, thereby inhibiting the formation and proliferation of tumor cells. Polyamines are involved in nucleosome oligomerization and DNA conformation, creating a chromatin environment that stimulates neoplastic transformation of cells. This agent has been shown to induce apoptosis in leiomyoma cells.

Bevonium methylsulfate, also known as CG201, is an antimuscarinic agent.

Xaliproden, also known as SR57746, is a drug which acts as a 5HT1A agonist. It has neurotrophic and neuroprotective effects in vitro, and has been proposed for use in the treatment of several neurodegenerative conditions including amyotrophic lateral sclerosis and Alzheimer's disease.

Vinflunine is a bi-fluorinated derivative of the semi-synthetic vinca alkaloid vinorelbine with antitubulin, antineoplastic, and antiangiogenic activities. Vinflunine inhibits tubulin assembly without any stablization of assembled microtubules at concentrations comparable to those of other vinca alkaloids such as vincristine, vinblastine and vinorelbine; this effect on microtubule dynamics results in cell cycle arrest in mitosis and apoptosis. Compared to other vinca alkaloids, this agent binds weakly to the vinca-binding site, indicating that vinflunine may exhibit reduced neurotoxicity.

Uridine triacetate is a drug used in the treatment of hereditary orotic aciduria and to treat patients following an overdose of chemotherapy drugs 5-fluorouracil or capecitabine, or in patients exhibiting early-onset, severe or life-threatening toxicity affecting the cardiac or central nervous system, and/or early-onset, unusually severe adverse reactions (e.g., gastrointestinal toxicity and/or neutropenia) within 96 hours following the end of 5-fluorouracil or capecitabine administration. Uridine triacetate was granted breakthrough therapy designation by FDA in 2015. Uridine triacetate is a prodrug of uridine.

Timcodar, also known as VX-853, is a novel multidrug resistance Inhibitor. Timcodar was under clinical trials to treat cancaners and other diseases. Timcodar potentiated the activity of ethidium bromide (EtBr), a model efflux substrate, against three clinically significant gram-positive pathogens: Staphylococcus aureus, Enterococcus faecalis, and Streptococcus pneumoniae. Similar to reserpine, VX-853 directly blocked EtBr efflux in S. aureus. Furthermore, VX-853 was effective in lowering the MICs of several clinically used antibiotics, including fluoroquinolones, suggesting that VX-853 are representatives of a new class of bacterial efflux inhibitors with the potential for use in combination therapy.

Terameprocol, also known as EM-1421, is a semi-synthetic tetra-methylated derivative of nordihydroguaiaretic acid (NDGA) and transcriptional inhibitor with potential antiviral, antiangiogenic, and antineoplastic activities. Terameprocol competes with the transcription factor Sp1 for specific Sp1 DNA binding domains within gene promoter regions during DNA synthesis. In virally-infected cells, blocking of the Sp1 binding site suppresses Sp1-regulated viral promoter activity and gene expression, thereby inhibiting viral transcription and replication.

Taltobulin, also known as HTI-286 and SPA-110, is a fully synthetic analog of the natural tripeptide hemiasterlin, inhibits tubulin polymerization and circumvents transport-based resistance to taxanes. HTI-286 was a potent inhibitor of proliferation (mean IC50 = 2.5 ?± 2.1 nm in 18 human tumor cell lines) and had substantially less interaction with multidrug resistance protein (P-glycoprotein) than currently used antimicrotubule agents, including paclitaxel, docetaxel, vinorelbine, or vinblastine.

Talaporfin sodium is a natural chlorophyll-based, and water soluble PDT photosensitizer consisting of chlorin e6, derived from chlorophyll, and L-aspartic acid with photosensitizing activity. After intratumoral activation by light emitting diodes, talaporfin sodium forms an extended high energy conformational state that generates singlet oxygen, which can kill target tissues with minimal side effects through vascular closure and apoptosis. Constant illumination can activate each molecule of talaporfin many times, resulting in a continuous supply of singlet oxygen molecules. Talaporfin kills all tumour cells in the targeted zone, rather than only the minority of cells undergoing rapid division, as in the case of chemotherapy.

Stannsoporfin ( SnMP), also known as Tin mesoporphyrin, is a porphyrin-Sn(IV) complex, is also a potent heme oxygenase inhibitor, that inhibits HO-1–mediated heme catabolism with potential medicinal application for the treatment of both neonatal jaundice and inherited hyperbilirubinemia syndromes. It was developed to possess unique structural and photophysical properties that make it a particularly potent and bioavailable in vivo inhibitor suitable for clinical use in newborns and studies to date have revealed a very favorable therapeutic profile with no significant adverse side effects.

Rubitecan is a semisynthetic agent related to camptothecin with potent antitumor and antiviral properties. Rubitecan binds to and inhibits the enzyme topoisomerase I and induces protein-linked DNA single-strand breaks, thereby blocking DNA and RNA synthesis in dividing cells; this agent also prevents repair of reversible single-strand DNA breaks.

Quinagolide is a selective, D2 receptor agonist (or prolactin-release inhibitor) that is used for the treatment of elevated levels of prolactin. Quinagolide (Norprolac) was approved in European Community, but not in USA as of December, 2011. Quinagolide prevents the production of a chemical called prolactin. Prolactin is involved in many processes within the body, such as milk production after childbirth and altering levels of hormones involved with controlling the menstrual cycle and fertility. Quinagolide is therefore helpful in reducing prolactin levels to reduce milk production for certain medical reasons and to treat some types of infertility, breast problems and menstrual disorders.

Sonolisib, also known as PX-866, is a small-molecule wortmannin analogue inhibitor of the alpha, gamma, and delta isoforms of phosphoinositide 3-kinase (PI3K) with potential antineoplastic activity. PI3K inhibitor PX-866 inhibits the production of the secondary messenger phosphatidylinositol-3,4,5-trisphosphate (PIP3) and activation of the PI3K/Akt signaling pathway, which may result in inhibition of tumor cell growth and survival in susceptible tumor cell populations. Activation of the PI3K/Akt signaling pathway is frequently associated with tumorigenesis and dysregulated PI3K/Akt signaling may contribute to tumor resistance to a variety of antineoplastic agents.

Picoplatin is a new generation organic platinum analog with an extended spectrum of antineoplastic activity. Designed to overcome platinum drug resistance, picoplatin alkylates DNA, forming both inter- and intra-strand cross-linkages, resulting in inhibition of DNA replication and transcription, and the induction of apoptosis.

Pelitrexol is a GARFT inhibitor, and is also a water soluble antifolate with anti-proliferative activity. Pelitrexol inhibits activity of glycinamide ribonucleotide formyltransferase (GARFT), the first folate-dependent enzyme of the de novo purine synthesis pathway essential for cell proliferation. Enzyme inhibition reduces the purine nucleotides pool required for DNA replication and RNA transcription. As a result, this agent causes cell cycle arrest in S-phase, and ultimately inhibits tumor cell proliferation.

Palifosfamide, also known as ZIO201, is a synthetic mustard compound with potential antineoplastic activity. An active metabolite of ifosfamide covalently linked to the amino acid lysine for stability, palifosfamide irreversibly alkylates and cross-links DNA through GC base pairs, resulting in irreparable 7-atom inter-strand cross-links; inhibition of DNA replication and cell death follow. Unlike ifosfamide, this agent is not metabolized to acrolein or chloroacetaldehyde, metabolites associated with bladder and CNS toxicities. In addition, because palifosfamide does not require activation by aldehyde dehydrogenase, it may overcome the tumor resistance seen with ifosfamide.

ONT-093, also known as OC-144-093, is an orally bioavailable P-glycoprotein pump inhibitor, for the potential reversal of multidrug resistance in patients undergoing cancer chemotherapy. ONT-093 could inhibit P-gp and reverse multidrug resistance at nM concentrations with no effect on paclitaxel pharmacokinetics. OC144-093 is the least non-specifically toxic Pgp inhibitor described to date, with an average cytostatic IC50 of >60 microM in 15 cell types. OC144-093 may represent an ideal candidate for use in enhancement of AED blood-brain barrier penetration.

NOV-002, also known as Glutathione disulfide, GSSG; oxidized glutathione, is a dimer of glutathione with potential chemoprotective and immunomodulating activities. Mimicking endogenous GSSG, glutathione disulfide acts as a competitive substrate for gamma-glutamyl-transpeptidase (GGT), which may result in the S-glutathionylation of proteins, predominantly actin, a redox stress on endoplasmic reticulum (ER), and ER stress-induced apoptosis; S-glutathionylation may be stimulated by reactive oxygen species (ROS) liberated by a glutathione disulfide NOV-002-induced increase in GGT activity.

Motexafin lutetium is a texaphyrin, marketed as Antrin by Pharmacyclics Inc. Motexafin lutetium is structurally a pentadentate aromatic metallotexaphyrin with photosensitizing properties. Motexafin lutetium preferentially accumulates in tumor cells due to their increased rates of metabolism and absorbs light, forming an extended high energy conformational state that produces high quantum yields of singlet oxygen, resulting in local cytotoxic effects. M otexafin lutetium is a photosensitiser for use in photodynamic therapy to treat skin conditions and superficial cancers. It has also been tested for use in photoangioplasty (photodynamic treatment of diseased arteries). It is photoactivated by 732 nm light which allows greater depth of penetration.

Lasofoxifene, also known as CP 336156, is a non-steroidal selective estrogen receptor modulator (SERM) for the prevention and treatment of osteoporosis and for the treatment of vaginal atrophy. In September 2005, Pfizer received a non-approvable letter from the U.S. Food and Drug Administration regarding lasofoxifene (trade name Oporia), a selective estrogen receptor modulator for the prevention of osteoporosis. Lasofoxifene was approved in the EU under the brand name Fablyn by the EMEA in March 2009. Lasofoxifene is a desmethyl dihydro analog of nafoxidine.

INSM-18, also known as nordihydroguaiaretic acid, NDGA and masoprocol, is a naturally occurring antioxidant dicatechol originally derived from the creosote bush Larrea divaricatta with antipromoter, anti-inflammatory, and antineoplastic activities. NDGA directly inhibits activation of two receptor tyrosine kinases (RTKs), the insulin-like growth factor receptor (IGF-1R) and the c-erbB2/HER2/neu receptor, resulting in decreased proliferation of susceptible tumor cell populations.

Aldoxorubicin, also known as INNO-206 and Doxo-EMCH, is the 6-maleimidocaproyl hydrazone derivative prodrug of the anthracycline antibiotic doxorubicin with antineoplastic activity. INNO-206 binds selectively to the cysteine-34 position of albumin via its maleimide moiety. Doxorubicin is released from the albumin carrier after cleavage of the acid-sensitive hydrazone linker within the acidic environment of tumors and, once located intracellularly, intercalates DNA, inhibits DNA synthesis, and induces apoptosis. Albumin tends to accumulate in solid tumors as a result of high metabolic turnover, rapid angiogenesis, hyervasculature, and impaired lymphatic drainage. Because of passive accumulation within tumors, this agent may improve the therapeutic effects of doxorubicin while minimizing systemic toxicity.

Iincyclinide, also known as CMT-3 and COL-3, is a MMP inhibitor and a chemically-modified tetracycline with potential antineoplastic activity. Incyclinide inhibits matrix metalloproteinases (MMPs), thereby inducing extracellular matrix degradation, and inhibiting angiogenesis, tumor growth and invasion, and metastasis. This agent also causes mitochondrial depolarization in tumor cells and induces both cellular apoptosis and tissue necrosis.

Symadex, also known as imidazoacridone; XLS-002 and C-1311, is a member of the novel imidazoacridinone family of anticancer agents. Imidazoacridone has shown activity in experimental tumour models both in vitro and in nude mice. C-1311 at the EC(99) dose delayed progression of cells through the S phase which was followed by G2 arrest. C-1311 does not induce rapid apoptosis in HT-29 cells, instead drug exposure leads to prolonged G2 arrest followed by G2 to M transit and cell death during mitosis in the process of mitotic catastrophe.

Hypothemycin is a resorcylic acid lactone polyketide that has fungicidal, kinase inhibitory, and anticancer properties. Hypothemycin inhibits MEK and other protein kinases containing a conserved cysteine residue in the ATP-binding domain. Hypothemycin inhibits proliferation of cancer cell lines dependent on activating mutations.

Exherin, also known as ADH-1, is a small, cyclic pentapeptide vascular-targeting agent with potential antineoplastic and antiangiogenic activities. ADH-1 selectively and competitively binds to and blocks N-cadherin, which may result in disruption of tumor vasculature, inhibition of tumor cell growth, and the induction of tumor cell and endothelial cell apoptosis. N-cadherin, a cell- surface transmembrane glycoprotein of the cadherin superfamily of proteins involved in calcium-mediated cell-cell adhesion and signaling mechanisms; may be upregulated in some aggressive tumors and the endothelial cells and pericytes of some tumor blood vessels.
