Dacuronium is an aminosteroid, acting as a competitive antagonist of nicotinic acetylcholine receptors. In animals, dacuronium worked as a short-acting muscle relaxant with a rapid onset of action. In a clinical trial, dacuronium was markedly less potent than tubocurarine and did not show a rapid recovery from its action.

CEP-11981 is an orally bioavailable inhibitor of vascular endothelial growth factor receptor (VEGFR) and Tie2 receptor tyrosine kinases with potential antiangiogenic and antineoplastic activities. Preclinical studies have shown that CEP-11981 exhibits promising permeability, metabolic stability, and pharmacokinetic properties across multiple species. Studies of pharmacologic activity across angiogenesis assays, animal tumor models, and human tumor models have shown sustained, dose-related antiangiogenic and antitumor inhibition. In clinical trals CEP-11981 administration leads to disease stabilization in patients with recurrent or refractory solid tumors. Despite acceptable tolerability of CEP-11981 at the MTD, further development by the sponsor has ceased.

AT-406 (DEBIO-1143, SM-406), is a potent and orally bioavailable Smac mimetic and an antagonist of the inhibitor of apoptosis proteins (IAPs). AT-406 inhibits cancer cell growth in various human cancer cell lines. It has good oral bioavailability in mice, rats, non-human primates, and dogs, is highly effective in induction of apoptosis in xenograft tumors, and is capable of complete inhibition of tumor growth. Debiopharm under a licence from Ascenta Therapeutics is developing AT-406 for the treatment of cancers.

Dihydrexidine, a novel full efficacy D1 dopamine receptor agonist. Dihydrexidine was shown to stimulate cyclic AMP synthesis just as well or better than dopamine. It was the first dopamine D1 receptor agonist that had potent antiparkinsonian activity in a primate model of Parkinson's disease. Dihydrexidine produces hypothermia. Dihydrexidine has been shown to alleviate cognitive deficits or enhance cognitive performance in a number of animal models of cognition. It is under investigation for the improving the cognitive and working memory deficits in schizophrenia and schizotypal disorder.

I-BET-762 (GSK 525762) is a small molecule benzodiazepine, by 'mimicking' acetylated histones interferes with the recognition of acetylated histones by BET family of bromodomains (BRD2, BRD3, and BRD4), which disrupts chromatin remodeling and gene expression. Prevention of the expression of certain growth-promoting genes may lead to an inhibition of tumour cell growth. GlaxoSmithKline is developing GSK 525762 for the oral treatment of solid tumours and haematological malignancies.

TIC10 (TIC10 isomer or ONC201 isomer) is a potent, orally active, and stable small molecule and is an efficacious antitumor therapeutic agent that acts on tumor cells and their microenvironment to enhance the concentrations of the endogenous tumor necrosis factor-related apoptosis-inducing ligand (TRAIL). The isomeric structure of TIC10/ONC201 is critical to its activity: anti-cancer activity is associated with the angular structure and not the linear TIC10 isomer. TIC10 transcriptionally induces a sustained up-regulation TRAIL in tumors and normal cells in a p53-independent manner. TIC10 inactivates kinases Akt and extracellular signal-regulated kinase (ERK), leading to the translocation of Foxo3a into the nucleus, where it binds to the TRAIL promoter to up-regulate gene transcription. TIC10 crosses the blood-brain barrier. TIC10 treatment caused tumor regression in the HCT116 p53−/− xenograft, RKO human colon cancer xenograft–bearing mice and human triple-negative breast cancer xenografts and significantly prolonged the survival of Eμ-myc transgenic mice, which spontaneously develop metastatic lymphoma from weeks 9 to 12 of age by 4 weeks.

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.
