Zinc telluride is a binary chemical compound with the formula ZnTe. Zinc telluride (ZnTe) is a wide-band-gap II–VI semiconductor (E g=2.25 eV at 300 K) crystallizing in the cubic, zinc-blende structure. This material is promising for application as a purely green light-emitting diode. As Zinc telluride can be easily doped, and for this reason it is one of the more common semiconducting materials used in optoelectronics. Zinc telluride finds applications in the following: LEDs and laser diodes Solar cells Tetrahertz imaging Electro-optic detector Holographic interferometry Laser optical phase conjugation devices. Gold–zinc telluride (Au–ZnTe) core–shell nanoparticles were synthesized to support surface modifications for enhanced drug delivery in cancer therapeutics.

GlaxoSmithKline is developing GSK-356278 as a selective, brain-penetrant phosphodiesterase 4 (PDE4) inhibitor that demonstrates anxiolytic and cognition-enhancing effects. Small molecule phosphodiesterase (PDE) 4 inhibitors have long been known to show therapeutic benefit in various preclinical models of psychiatric and neurologic diseases because of their ability to elevate cAMP in various cell types of the central nervous system. The drug was studied for the treatment of Huntington's disease, depressive and anxiety disorders. GSK-356278 has completed phase I clinical trials for evaluation of the safety, tolerability, and pharmacokinetics in male volunteers with the therapeutic dose for future clinical development.

Dideoxyadenosine (2′,3′-dideoxyadenosine) is a prodrug form of didanosine (2',3'-dideoxyinosine), a nucleoside reverse transcriptase inhibitor analog of adenosine. 2',3'-Dideoxyadenosine and 2',3'-dideoxyinosine were shown to be equally effective in the inhibition of HIV proliferation in human T cells. Dideoxyadenosine competitively inhibits adenylyl cyclase, thereby reducing levels of cyclic adenosine monophosphate (cAMP). By inhibiting cAMP-mediated gene activation in tumor cells, this agent may retard tumor cell proliferation. 2',3'-dideoxyadenosine inhibits retroviral DNA synthesis and mRNA expression in T cells exposed to the virus that causes acquired immunodeficiency syndrome, and affords such cells long-term protection in vitro under conditions of substantial viral excess. 2',3'-dideoxyadenosine appears to completely block reverse transcription from viral RNA to viral DNA. 2',3'-dideoxyadenosine was also shown not only to possess antibacterial activity in vitro against a variety of Enterobacteriaceae, but also to be effective in vivo, dideoxyadenosine was active in experimental mouse infections by the oral route against 5 Salmonella strains, 2 of 3 Arizona strains, 5 of 7 Citrobacter strains, 3 of 8 Klebsiella strains, 3 of 5 Escherichia strains, 1 of 3 Shigella strains, and 3 of 15 Serratia strains at concentrations generally well below the toxic level.

ITX-5061, an arylketoamide derivative, is a scavenger receptor B1 antagonist and a potent hepatitis C virus (HCV) entry inhibitor. It entered phase I clinical trial in liver transplant recipients with HCV but the trial was terminated.

Tungstic acid is a fairly strong acid, it catalyzes the oxidation by hydrogen peroxide of alkenes to the corresponding epoxides. Tungstic acid is widely used in the production of tungsten metal, alloys, and is used as a mordant for textiles and plastics. Tungstic acid has been reported to rapidly precipitate the quaternary ammonium cations in cholinergic nerve terminals, such as ACh or choline. Also, tungsten dietary supplementation has successfully been used to reduce xanthine oxide (XO) activity, resulting in decreased gastrointestinal (GI) mucosal damage because of lowered XO activity. Tungstic acid has been shown to effectively antagonize stress-induced gastric ulcers, possibly by decreasing motility and mass cell degranulation. Tungstic acid gel has been used as an epileptogenic agent since 1960. Epilepsy produced by this agent is characterized by good localization, short latency and limited duration. It is effective in cerebral cortex, brain stem and spinal cord.

T-2000 is an oxopyrimidine derivative patented by Taro Pharmaceutical Industries Ltd. as a tranquilizing agent. T-2000 acts as a modulator of GABA A receptor with well-documented anticonvulsant activity and little sedation in animal models. In vitro, equimolar concentrations of T-2000 and phenobarbital produce equivalent enhancement of GABA-evoked chloride currents. Unfortunately, in clinical trials T-2000 failed to demonstrate efficacy in older patients with essential tremor. Moreover, daily administration of T2000 resulted in higher total blood barbiturate levels, likely accounting for the poor tolerability.

Gantacurium (GW280430A) is an ultrashort-acting neuromuscular blocking agent with a rapid onset and a wide safety margin, and is one of the most recent neuromuscular blocking agents that have shown potential for clinical application. It is an asymmetric enantiomeric isoquinolinium diester of chlorofumaric acid. The neuromuscular properties of gantacurium (such as spontaneous recovery of a neuromuscular block induced by the compound) were comparable with the depolarizing neuromuscular blocking drug succinylcholine, but without the unwanted side effects of this depolarizing neuromuscular blocking drug. Gantacurium is, due to its unique metabolism, rapidly inactivated by cysteine adduction and alkaline hydrolysis.

GPX-150 is an anthracycline compound that is being tested for treatment in patients with soft-tissue sarcomas. This doxorubicin (DOX) analog does not show the cumulative dose-dependent cardiotoxicity of DOX. It works by reducing the formation of reactive oxygen species and the cardiotoxic metabolite, doxorubiciniol, the two pathways that are linked to the irreversible cardiotoxicity seen with DOX. Phase 1 clinical trials showed no irreversible, cumulative dose-dependent cardiotoxicity. A phase 2 study investigating the safety and efficacy of GPX-150 in patients with soft tissue sarcoma has been completed. No patients developed any evidence of irreversible, cumulative dose-dependent chronic cardiotoxicity. Toxicities reported include grade 3 anemia, neutropenia, and grade 4 leukopenia.

LY2452473 is a selective androgen receptor modulator (SARM), with potential tissue-selective androgenic/anti-androgenic activity. Upon oral administration, LY2452473 acts as an agonist in select tissues and organs, including skeletal muscle, bone and the penis, thereby binding to and activating androgen receptor (AR) while acting as an antagonist in the prostate, thereby blocking AR activation and AR-mediated cellular proliferation. This may improve muscle mass and strength, bone formation, and erectile dysfunction while not stimulating growth of the prostate. Eli Lilly was developing LY 2452473/tadalafil combination for the treatment of erectile dysfunction. In addition, Eli Lilly is studying the use of a targeted LY 2452473 therapy, as a possible improvement in quality of life for prostate cancer patients who have undergone radical prostatectomy.
