Dexefaroxan is a selective alpha 2-adrenergic receptor antagonist. Вexefaroxan improved TgCRND8 (protein-transgenic mouse model of Alzheimer's disease) behavioral phenotypes and increased BDNF mRNA expression without affecting amyloid-β peptide levels. Dexefaroxan treatment also enhanced the number and complexity of the dendritic arborizations of polysialated neural cell adhesion molecule-positive neurons. The trophic effects of dexefaroxan on newborn cells might involve an increase in brain-derived neurotrophic factor, which was upregulated in afferent noradrenergic fiber projection areas and in neurons in the granule cell layer. By promoting the survival of new endogenously formed neurons, dexefaroxan treatment represents a potential therapeutic strategy for maintaining adult neurogenesis in neurodegenerative conditions, such as Alzheimer's disease, that affect the hippocampus. Dexefaroxan increases neuron survival in the olfactory bulb of the adult rat in vivo, putatively as a result of reducing the apoptotic fate of telencephalic stem cell progenies.

Posaraprost is the anti-inflammatory compound.

Anacetrapib is a CETP inhibitor being developed by Merck to treat hypercholesterolemia (elevated cholesterol levels) and prevent cardiovascular disease. Anacetrapib is a cholesterol ester transfer protein (CETP) inhibitor that blocks the transfer of cholesterol from highdensity lipoprotein to other lipoproteins. This results in an increase in high-density lipoprotein cholesterol (HDL-C) and a decrease in lowdensity lipoprotein cholesterol (LDL-C), which may reduce the development of atherosclerosis. Anacetrapib has not been approved for sale in Canada or the United States. Clinical evidence to support the use of anacetrapib for dyslipidemia has been reported in two clinical trials. REVEAL is an ongoing, large-scale phase 3 trial evaluating the effectiveness of anacetrapib with a statin for the secondary prevention of major coronary events in patients who have a history of cardiovascular disease. Results are anticipated in January 2017.

Declenperone is an antagonist of 5-HT2 receptors, developed by Janssen Pharmaceutica. The compound is claimed to have strong neuroleptic activity, as evidenced by experimental data obtained in apomorphine-tryptamine and norepinephrine test in rats, and the apomorphine test in dogs. Declenperone was used in a veterinary as a sedative.

Enzastaurin is a serine/threonine kinase inhibitor that showed antiangiogenic, antiproliferative, and proapoptotic properties in vitro and antitumor activity in vivo in a xenograft Waldenström macroglobulinemia (WM) model. Enzastaurin (LY317615) is a potent PKCβ selective inhibitor. Enzastaurin suppresses angiogenesis and was advanced for clinical development based upon this antiangiogenic activity. Enzastaurin suppresses tumor growth through multiple mechanisms: direct suppression of tumor cell proliferation and the induction of tumor cell death coupled to the indirect effect of suppressing tumor-induced angiogenesis. Enzastaurin is an orally administered drug that was intended for the treatment of solid and haematological cancers. Enzastaurin had shown encouraging preclinical results for the prevention of angiogenesis, inhibition of proliferation and induction of apoptosis as well as showing limited cytotoxicity within phase I clinical trials. However, during its assessment in phase II and III clinical trials the efficacy of enzastaurin was poor both in combination with other drugs and as a single agent. Eli Lilly discontinued development of enzastaurin after top-line data from the double-blind, international Phase III PRELUDE trial in 758 DLBCL patients showed that enzastaurin missed the primary endpoint of improving DFS vs. placebo.

Debropol is an aliphatic nitro compound, synthesized by The Boots Company. Debropol possesses antimicrobial activity against Pseudomonas aeruginosa.

Epervudine (5-isopropyl-2'-deoxyuridine) is an antiviral compound. The antiviral effect of epervudine on herpes viruses (HSV-1 and HSV-2) is based on the sensitivity of virus DNA to nucleases due to epervudine incorporation into the virus DNA and the resulting change in DNA conformation. Virus selectivity is based on virus induced thymidine kinase activity and on HSV induction of polymerase enzymes catalyzing the incorporation. Epervudine (HEVIZOS) ointment is used to treat herpetic skin infections.

Carabersat is an anticonvulsant devoid of cardiovascular side effects with minimal central nervous system adverse actions. Carabersat does not bind to ion channels, purinergic, aminergic, opioid and other peptidergic receptors. It selectively interacts with its own binding site, which is not yet elucidated. Carabersat has no effect on sodium channels, GABAergic or glutamate pathways. Carabersat had been in phase II clinical trials for the treatment of epilepsy. It has a potential action in preventing migraines because it acts through an inhibition of the cortical spreading depression trigeminal nerve-induced vasodilatation in cats. Its good therapeutic index and the markedly reduced neurological impairments could make it a useful agent for migraine prophylaxis pending efficacy parameters of controlled studies, which are underway.

Elgodipine (IQB-875, CAS 119413-55-7) is a phenyldihydropyridine derivative acting as a calcium channel antagonist. Elgodipine inhibited both T- and L-type calcium channels in a concentration-dependent manner. Elgodipine was in clinical trials for the treatment of cardiovascular diseases however its development has been discontinued.

Rimoprogin (VUFB-9244) is an antimycotic (antifungal) compound that was first reported in the literature in the 1970’s. It has been mentioned as a possible active agent in a plaster against dysfunctional nail growth, but there is no information on current development of rimoprogin for clinical use.
