NMED-160 (also known as MK-6721, NP-118809, Z-160) is a potent N-type calcium channel blockers, which has good selectivity over L-type calcium channels. Neuromed Pharmaceuticals developed this compound for the treatment of the chronic pain. However, that study was discontinued in 2007 in spite of absence of adverse events, but because drug did not demonstrate the ideal, pharmaceutical characteristics considered necessary to advance the compound further in development. Then Zalicus, Inc. was developing that drug for the treatment of chronic neuropathic pain associated with lumbosacral radiculopathy and post-herpetic neuralgia and drug was in the phase II clinical trial. Nevertheless, based on the result from trials, where Z160 did not meet the primary endpoint, Zalicus was also discontinuing the Z160 program.

Zoniporide hydrochloride is a novel, potent and selective NHE-1 inhibitor (IC50 = 14 nM). Reduces infarct size in the isolated heart (EC50 = 0.25 nM). Attenuates post-ischemic cardiac contractile dysfunction and ischemia-reperfusion-induced ventricular fibrillation in vivo. Zoniporide hydrochloride represents a novel class of potent and selective human NHE-1 inhibitors with potential utility for providing cardioprotection in a clinical setting.

Posizolid (AZD2563 or AZD5847) is an oxazolidinone, identified from an antibiotic research programme which aimed to synthesise agents that inhibited all Gram-positive bacteria, including multiresistant strains likely to be encountered clinically. Oxazolidinones bind to the 50S ribosomal subunit and inhibit the initiation phase of translation. Posizolid had been in phase II clinical trials for the treatment of tuberculosis. However, this study was discontinued.

DB05448 (PX-12, 1-methyl propyl 2-imidazolyl disulfide) is a small molecule irreversible inhibitor of the redox protein thioredoxin, which has been associated with cancer and tumor growth. DB05448 stimulates apoptosis, down-regulates HIF-1α and vascular endothelial growth factor (VEGF) and inhibits tumor growth in animal models. Since high levels of Trx-1 have been associated with colorectal, gastric and lung cancers, DB05448 is indicated as a potential cancer treatment in combination with chemotherapy for patients with advanced metastatic cancer. Initial trials correlated doses of DB05448 with increased patient survival.

Tecadenoson is a novel selective A1 adenosine receptor agonist that is currently being evaluated for the conversion of paroxysmal supraventricular tachycardia (PSVT) to sinus rhythm. Adenosine is a naturally occurring compound that stimulates all adenosine receptor subtypes in the body, including the A2 adenosine receptor which lowers blood pressure. In non-clinical trials, tecadenoson selectively stimulated the A1 adenosine receptor in the Atrioventricular node (AV node) and slowed the speed of electrical conduction across the AV node, reducing the number of electrical impulses that reached the ventricle, without affecting blood pressure. Clinical studies to date with intravenous tecadenoson suggest that it may slow the speed of AV nodal conduction by selectively stimulating the A1 adenosine receptor, and may avoid blood pressure lowering by not stimulating the A2 adenosine receptor. Thus, it may be possible to use intravenous tecadenoson to convert patients from PSVT to normal sinus rhythm without lowering blood pressure or causing adverse events related to vasodilation such as flushing, palpitations or a headache.

Darinaparsin is a novel mitochondrial-targeted agent being developed for the treatment of various hematologic and solid cancers. In a Phase II study in the US, intravenous darinaparsin demonstrated evidence of clinical activity in malignant lymphoma, and in particular peripheral T-cell lymphoma (PTCL). Darinaparsin was granted Orphan Drug Designation in the US and Europe as a treatment of PTCL. The oral formulation is also being tested in Phase I for the treatment of solid tumors. Darinaparsin induces G2/M cell cycle arrest and apoptosis in tumor cells, primarily through disruption of mitochondrial functions, increased reactive oxygen species (ROS) production and modulation of signal transduction pathways.
CI 1040 is an inhibitor of the mitogen-activated protein (MAP) kinase signal transduction pathway and has been shown to specifically inhibit MAP kinase kinase (MEK). CI 1040 was being developed by Parke-Davis (formerly a division of WarnerLambert, Now Pfizer) as an anticancer agent. It was the initial MEK inhibitor to undergo clinical evaluation based on promising preclinical activity. However, its development has been discontinued.

Forasartan (also known as SC-52458) was developed as an orally active, competitive angiotensin (Ang) II subtype 1 (AT1)-receptor antagonist for the treatment of hypertension. Forasartan competes with angiotensin II for binding at the AT1 receptor subtype. It is known that angiotensin II is a vasoconstrictor and stimulates the synthesis and release of aldosterone, and blockage of its effects results in a decrease in systemic vascular resistance. Information about the further development of forasartan is not available.

Fialuridine I-124 is an isotope-labeled form of fialuridine, or 1-(2-deoxy-2-fluoro-1-D-arabinofuranosyl)-5-iodouracil (FIAU), a thymidine nucleoside analog with activity against various herpesviruses and hepatitis B virus (HBV) in vitro and in vivo. Bacterial or herpes virus thymidine kinase (TK) considered to be a target of FIAU. Fialuridine I-124 is a positron emission tomography/computed tomography (PET/CT) tracer that was developed for imaging of cells transfected with the herpes simplex virus 1 (HSV1) thymidine kinase reporter gene. This enzyme transfers a γ phosphate group fom ATP to the 5’ hydroxyl group of pyrimidine deoxynucleosides. The lipophilic tracer diffuses into the cell and is trapped in the cell with HSV1-TK activity, because the phosphorylated tracer cannot pass the plasma membrane. TK gene of bacteria was sufficiently similar to that of the viral TK of HSV1 and fialuridine I-124 could also be phosphorylated by the endogenous bacterial TK. Once phosphorylated by TK, fialuridine I-124 becomes trapped within bacteria and can be detected with positron emission tomography/computed tomography (PET/CT).
Lomeguatrib is a O6-methylguanine-DNA-methyl-transferase inhibitor which was developed by AstraZeneca for the treatment of cancer. It was tested in phase I and II of clinical trials for the treatment of colorectal cancer, melanoma and other solid tumors.
