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. Note: The old CAT# for this product was 201350A

Eniluracil, also known as GW776 and GW776C85, is an orally active and irreversible inhibitor of dihydropyrimidine dehydrogenase. Eniluracil inhibits dihydropyrimidine dehydrogenase, the rate-limiting enzyme that catabolizes and inactivates 5-fluorouracil (5-FU) in the liver. Co-administration of ethynyluracil permits the oral administration of 5-FU. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus).

Efaproxiral, also known as RSR13, is an analogue of the cholesterol drug bezafibrate developed for the treatment of depression, traumatic brain injury, ischemia, stroke, myocardial infarction, diabetes, hypoxia, sickle cell disease, hypercholesterolemia and as a radio sensitiser. One use for efaproxiral is to increase the efficacy of certain chemotherapy drugs which have reduced efficacy against hypoxic tumours, and can thus be made more effective by increased offloading of oxygen into the tumour tissues

Darinaparsin, also know as ZIO-101 and SP-02, is a small-molecule organic arsenical with potential antineoplastic activity. Although the exact mechanism of action is unclear, darinaparsin, a highly toxic metabolic intermediate of inorganic arsenicals (iAs) that occurs in vivo, appears to generate volatile cytotoxic arsenic compounds when glutathione (GSH) concentrations are low. The arsenic compounds generated from darinaparsin disrupt mitochondrial bioenergetics, producing reactive oxygen species (ROS) and inducing ROS-mediated tumor cell apoptosis; in addition, this agent or its byproducts may initiate cell death by interrupting the G2/M phase of the cell cycle and may exhibit antiangiogenic effects.

CVT-6883, also known as GS6201 is a selective A2B adenosine antagonist, represents a novel potential approach to treating cardiopulmonary diseases. A pre-clinical study showed that CVT-6883 significantly reduced elevated markers of inflammation, fibrosis and pulmonary injury in in vivo preclinical models.

Crolibulin, also known as EPC2407 and crinobulin, is a small molecule tubulin polymerization inhibitor with potential antineoplastic activity. Microtubulin inhibitor EPC2407 binds to the colchicine-binding site on beta-tubulin and inhibits the polymerization of tubulin into microtubules, which may result in cell cycle arrest, the induction of apoptosis, and the inhibition of tumor cell proliferation. As a vascular disruption agent (VDA), this agent also disrupts tumor neovascularization, which may result in a reduction in tumor blood flow and tumor hypoxia and ischemic necrosis.

Becatecarin, also known as BMY-27557, XL119 and BMS-181176, is a synthetic diethylaminoethyl analogue of the indolocarbazole glycoside antineoplastic antibiotic rebeccamycin. Becatecarin intercalates into DNA and stabilizes the DNA-topoisomerase I complex, thereby interfering with the topoisomerase I-catalyzed DNA breakage-reunion reaction and initiating DNA cleavage and apoptosis.

Sardomozide HCl, also known as SAM486A or CGP48664, is a second-generation polyamine synthesis inhibitor, which inhibits the activity of the polyamine biosynthetic enzyme S-adenosylmethionine decarboxylase (SAMDC). SAM486 is more potent and specific than the first-generation SAMDC inhibitor methylglyoxal (bis) guanylhydrazone (MGBG). Preclinical testing confirmed promising antiproliferative activity. The in vitro tests showed that p53 wild-type NB cells were highly sensitive to SAM486A treatment. Most notably, SAM486A treatment resulted in the rapid accumulation of proapoptotic proteins p53 and Mdm2.

Apricoxib, also known as Benzenesulfonamide 42(4ethoxyphenyl)4methyl1Hpyrrol1yl, is an orally bioavailable nonsteroidal anti-inflammatory agent (NSAID) with potential antiangiogenic and antineoplastic activities. Apricoxib binds to and inhibits the enzyme cyclooxygenase-2 (COX-2), thereby inhibiting the conversion of arachidonic acid into prostaglandins. Apricoxib-mediated inhibition of COX-2 may induce tumor cell apoptosis and inhibit tumor cell proliferation and tumor angiogenesis. COX-related metabolic pathways may represent crucial regulators of cellular proliferation and angiogenesis.

Alanosine, also known as L-alanosine, is an amino acid analogue and antibiotic derived from the bacterium Streptomyces alanosinicus with antimetabolite and potential antineoplastic activities. L-alanosine inhibits adenylosuccinate synthetase, which converts inosine monophospate (IMP) into adenylosuccinate, an intermediate in purine metabolism. L-alanosine-induced disruption of de novo purine biosynthesis is potentiated by methylthioadenosine phosphorylase (MTAP) deficiency. The clinical use of this agent may be limited by its toxicity profile. MTAP is a key enzyme in the adenine and methionine salvage pathways.

Triptorelin is a gonadotropin-releasing hormone agonist (GnRH agonist) used as the acetate or pamoate salts. By causing constant stimulation of the pituitary, it decreases pituitary secretion of gonadotropins luteinizing hormone (LH) and follicle stimulating hormone (FSH). Like other GnRH agonists, triptorelin may be used in the treatment of hormone-responsive cancers such as prostate cancer or breast cancer, precocious puberty, estrogen-dependent conditions (such as endometriosis or uterine fibroids), and in assisted reproduction. It is also used as therapy in cases of gender dysphoria.

Miriplatin (MPT) is a novel platinum complex used in TACE that shows promise for the treatment of hepatocellular carcinoma (HCC). Miriplatin is a lipophilic platinum complex that can be easily suspended in Lipiodol and gradually releases active platinum compounds in tumor tissue. Miriplatin is less severe toxicity profile compared to other platinum anticancer agents.

Mitoxantrone is an anthraquinone that intercalates in DNA and inhibits topoisomerase II (IC50 = 5.3 μM), thus inhibiting cell proliferation. It also inhibits HIV-1 integrase (IC50 = 3.8 μM). Mitoxantrone is exported from cells in an ATP- and glutathione-dependent manner by multidrug resistance protein-1.4 Formulations containing mitoxantrone have been used in the treatment of cancer and multiple sclerosis.

Misonidazole is a radiosensitizer used in radiation therapy to cause normally resistant hypoxic tumor cells to become sensitive to the treatment.

Amikacin is an antibiotic used for a number of bacterial infections. This includes joint infections, intraabdominal infections, meningitis, pneumonia, sepsis, and urinary tract infections. It is also used for the treatment of multidrug-resistant tuberculosis. It is used either by injection into a vein or muscle. Amikacin is in the aminoglycoside family of medications. It works by blocking the function of the bacteria's 30S ribosomal subunit, making it unable to make protein.

Triptorelin, a decapeptide (pGlu-His-Trp-Ser-Tyr-D-Trp-Leu-Arg-Pro-Gly-NH2), is a gonadotropin-releasing hormone agonist (GnRH agonist) used as the acetate or pamoate salts. By causing constant stimulation of the pituitary, it decreases pituitary secretion of gonadotropins luteinizing hormone (LH) and follicle stimulating hormone (FSH). Like other GnRH agonists, triptorelin may be used in the treatment of hormone-responsive cancers such as prostate cancer or breast cancer, precocious puberty, estrogen-dependent conditions (such as endometriosis or uterine fibroids), and in assisted reproduction. It is also used as therapy for gender identity disorder.

Pipobroman (trade names Vercite, Vercyte) is an anti-cancer drug that probably acts as an alkylating agent. It is marketed by Abbott Laboratories. Pipobroman (PB) has well documented clinical activity in polycythemia vera (PV) and essential thrombocythemia (ET).
