Filgotinib (GLPG0634) is a highly selective JAK1 inhibitor. GLPG0634 is a promising drug candidate for the future treatment of autoimmune and inflammatory disorders. It is in phase III clinical trials (initiated mid-2016) for the treatment of rheumatoid arthritis, Crohn's disease and ulcerative colitis. Most common adverse events observed were infections, gastrointestinal disorders and nervous system disorders.

Encenicline (EVP-6124; MT-4666) acts as a potent partial and selective agonist at alpha-7 nicotinic acetylcholine receptor. Encenicline significantly improved memory function in animal models. FORUM Pharmaceuticals (formerly EnVivo Pharmaceuticals) is developing encenicline for the treatment of cognition disorders such as schizophrenia and for Alzheimer's disease.

Ruboxistaurin is an orally bioavailable, selective, potent inhibitor of protein kinase C β developed for treating diabetic retinopathy. In vitro and in vivo non-clinical models have demonstrated that Ruboxistaurin decreases PKC β activity and ameliorates many of the effects of PKC β on pathologic processes in the retina. Ruboxistaurin prevents the slowing of retinal blood flow that is observed by fluorescein video angiography in the eyes of diabetic rats. It is also reported to cause regression of retinal neovascularization produced by laser-induced major branch vein occlusions in a porcine model. Ruboxistaurin positively affected the diabetes-induced retinal blood flow abnormalities in a Phase Ib study in diabetic patients. Ruboxistaurin is in phase III clinical trials for the treatment of diabetic nephropathy and diabetic macular edema. Eli Lilly had submitted Ruboxistaurin for approval in the US and the EU; however, the company subsequently discontinued development as it was unable to demonstrate sufficient efficacy

Flumatinib (HHGV678) is an orally bioavailable antineoplastic tyrosine kinase inhibitor. Flumatinib inhibits the wild-type forms of Bcr-Abl, platelet-derived growth factor receptor (PDGFR) and mast/stem cell growth factor receptor (SCFR; c-Kit) and forms of these proteins with certain point mutations. Flumatinib was extensively metabolized after oral administration, and the major metabolic pathways observed were amide hydrolysis, demethylation, oxidation, and glucuronide conjugation. It is in phase III clinical trials for the treatment of Chronic myeloid leukemia (in China).

Sumanirole is a novel dopamine agonist with high affinity and efficacy at D2 dopamine receptors and has a substantial degree of selectivity for the D2 receptor over other dopamine receptor subtypes. It had been in clinical trials for the treatment of Parkinson’s disease and restless leg syndrome but these studies were terminated for the efficacy reason.

Fipamezole is a fluorine substituted imidazole compound with high antagonist specificity for the presynaptic alpha2-adrenoceptor. There were no significant differences between the affinity of Fipamezole for the different subtypes, thus characterizing Fipamezole as a non-subtype–selective alpha2 antagonist. Fipamezole had been in phase III clinical trials for the treatment of dyskinesia associated with Parkinson’s disease. Detected side effects are hypertension, nausea, vomiting, dysgeusia, facial flushing.

Dexverapamil (R-verapamil) is an enantiomer of verapamil. R-isomer behaved as an inhibitor of multidrug-resistant protein MRP1 (involved in the cancer cell multidrug resistance phenotype). It was developed by Knoll (BASF Pharma) as a chemosensitiser and/or modulator of multidrug resistance for use in combination with cancer chemotherapy. Dexverapamil was undergoing phase II clinical studies in France, Italy, Spain, United Kingdom and the US in patients with various cancers. It was also undergoing phase I clinical trials in Japan where it was licensed to Mitsui and Mitsui Toatsu Chemicals. However, development was discontinued. Dexverapamil (R-verapamil) has been developing by AGI therapeutics for the treatment of Irritable bowel syndrome however development was discontinued.

Elesclomol (also known as STA-4783), originally identified in a cell-based phenotypic screen for pro-apoptotic activity, is a novel small-molecule that potently induces apoptosis of cancer cells through the rapid generation of reactive oxygen species (ROS) and the induction of unmanageable levels of oxidative stress. Elesclomol exhibits antitumor activity against a broad spectrum of types of cancer cell in human tumour xenograft models due to its excessive ROS production and elevated levels of oxidative stress leading to the death of cancer cells. Elesclomol is currently being studied as novel cancer therapeutic, in which it has demonstrated the ability to prolong progression-free survival in study subjects. Elesclomol induces oxidative stress by provoking a buildup of reactive oxygen species within cancer cells. Elesclomol requires a redox-active metal ion to function; the Cu(II) complex is 34 times more potent than the Ni(II) complex and 1040-fold more potent than the Pt(II) complex. Elesclomol is an HSP-90 Inhibitor with pro-apoptotic and potential antineoplastic activities. Elesclomol induces oxidative stress and triggers mitochondrial-induced apoptosis in cancer cells. Elesclomol is being developed by Synta Pharmaceuticals and GlaxoSmithKline as a chemotherapy adjuvant and has received both fast track and orphan drug status from the U.S. Food and Drug Administration for the treatment of metastatic melanoma. Synta Pharmaceuticals announced on February 26, 2009, the suspension of all clinical trials involving Elesclomol due to safety concerns. In March 2010, Synta announced that the FDA had approved resuming clinical development of elesclomol, and that they expected to initiate one or more clinical trials for elesclomol in the second half of the year. In a small, randomized phase II study, elesclomol was shown to significantly increase progression-free survival in people with metastatic melanoma when given in addition to paclitaxel (Taxol).

TAK-875 (Fasiglifam) is the potent, selective and orally bioavailable GPR40 agonist. The drug was in Phase III clinical trials for the treatment of type 2 diabetes mellitus. Termination phase III development of TAK-875 for the potential treatment of type-2 diabetes mellitus was announced in 2013 due to concerns about liver safety.
