Talibegron (ZD2079) is a β3 adrenoceptor agonist and insulin sensitiser. It was developed as a potential treatment for obesity and non-insulin-dependent diabetes mellitus. Talibegron hydrochloride had been in phase II clinical trials by AstraZeneca for the treatment of type 2 diabetes and obesity. However, this research has been discontinued.

The BET-bromodomain inhibitor OTX015 (MK-8628) was initially developed by Mitsubishi Tanabe Pharma Corporation, but then was licensed by OncoEthix, privately held biotechnology company. OTX015 is a selective bromodomains: BRD2, BRD3, and BRD4 inhibitor and inhibits their binding to AcH4. Bromodomains have an important role in the targeting of chromatin-modifying enzymes to specific sites, including methyltransferases, HATs and transcription factors and regulate diverse biological processes from cell proliferation and differentiation to energy homeostasis and neurological processes. OTX015 has potent antiproliferative activity accompanied by c-MYC down-regulation in several tumor types, and has demonstrated synergism with the mTOR inhibitor everolimus in different models. Oral administration of OTX-015 markedly inhibited tumor growth and reduced tumor volume. OTX015 is currently in Phase 1b studies for the treatment of hematological malignancies and advanced solid tumors such as Triple Negative Breast Cancer, Non-small Cell Lung Cancer, Castrate-resistant Prostate Cancer (CRPC) and Pancreatic Ductal Adenocarcinoma. In addition, OTX015 was in phase II for the treatment of Glioblastoma Multiforme, but there were not detected clinical activity of the drug in the treatment populations and trial was closed.

Danusertib is a serine/threonine kinase inhibitor of multiple kinases, including aurora-A, B, and C. It also inhibits several cancer related tyrosine kinases as well as Abl, Trk-a, fibroblast growth receptor-1 and Ret. Danusertib is in phase II trials for the treatment of solid tumours, prostate cancer and chronic myeloid leukemia (CML). The most frequently reported side effects were neutropenia, nausea, anorexia, fatigue, and diarrhea.

Ipatasertib, an investigational Akt inhibitor, is currently in clinical development based on its potential to specifically target Akt in tumors with activated Akt signaling. Preclinical data have shown that ipatasertib selectively decreased cell viability and increased apoptosis in tumor cell lines characterized by activated Akt. Ipatasertib is advancing in clinical development including three Phase 2 trials in patients with breast cancer, gastric cancer and prostate cancer. The most commonly reported adverse events associated with Ipatasertib were Grade 1-2 diarrhea, nausea, fatigue, vomiting, decreased appetite and rash.

Ezutromid (SMTC-1100) is a small molecule utrophin upregulator. Ezutromid was identified from an iterative analoging approach from initial hits identified using a human muscle-specific utrophin A promoter cell-based assay. It increases both utrophin RNA and protein resulting in a significant reduction in dystrophic symptoms and increased muscle function in dystrophin-deficient mdx mice ( a mouse model of Duchenne muscular dystrophy (DMD)). Ezutromid was deemed safe and well tolerated in a Phase 1a healthy volunteer study and successfully completed a Phase 1b study in DMD boys. Summit Therapeutics is developing Ezutromid for the treatment of Duchenne muscular dystrophy.

Refametinib (RDEA-119, BAY- 869766) is a highly potent and selective inhibitor of mitogen-activated ERK kinase (MEK1/2) activity, Refametinib binds to an allosteric pocket adjacent to the ATP binding site, locking the enzyme in a catalytically inactive conformation. This compound is highly efficacious at inhibiting cell proliferation in several tumor cell lines in vitro. In vivo, Refametinib exhibits potent activity in xenograft models of cancers. Ardea Biosciences (a subsidiary of AstraZeneca) and Bayer HealthCare are developing refametinib for the treatment of cancer. The sulfonamide agent was originally developed by Valeant Pharmaceuticals International. Refametinib is in phase II development for hepatocellular carcinoma, and phase I/II development for pancreatic cancer and other solid tumours.

Ralimetinib (LY2228820), a trisubstituted imidazole derivative, is a potent and selective, ATP-competitive inhibitor of the α- and β-isoforms of p38 mitogen-activated protein kinase. LY2228820 produced significant tumor growth delay in multiple in vivo cancer models (melanoma, non-small cell lung cancer, ovarian, glioma, myeloma, breast). Eli Lilly is developing ralimetinib for the treatment of cancer.

Vipadenant (V2006) is a small molecule, adenosine A2A receptor antagonist that was being investigated in Parkinson's disease. Due to safety concerns development ceased in 2010 and the rights were regained from Biogen Idec in 2011 with no further investment made. In October 2014, RedoxTherapies licensed Vipadenant as it has the potential to disrupt an immunosuppressive mechanism of tumour protection, generating improved efficacy for immunotherapies of certain cancers when used in combination with other drugs.

Bimosiamose, discovered by Encysive Pharmaceutical and presently being developed by Revotar Biopharmaceuticals, is an 863 g/mol molecular weight dimer with minimal carbohydrate content and is, to date, the leading selectin inhibitor in clinical development. It was developed as anti-inflammatory drug fir the treatment of acute chronic inflammatory disorders including COPD. This compound has shown promise in a phase IIa 'proof of concept' trial in patients with asthma, reducing airway recruitment of eosinophils after intravenous administration. In acute lung injury, neutrophils (a type of white blood cells, thus belonging to the group of cells of the body’s defence system-the immune system) are drawn to the small lung bloodvessels and migrate into the air sacs (alveoli). There they release substances, which cause the inflammation leading to further destruction of the lung tissue. Bimosiamose disodium is expected to hinder the migration of these neutrophils into the alveoli.

Dacinostat (also known as LAQ824), is a hydroxamate histone deacetylase inhibitor with potential anticancer activity. Dacinostat inhibits histone deacetylase enzymatic activities in vitro and transcriptionally activated the p21 promoter in reporter gene assays. Tumor cells treated with Dacinostat caused acetylation of HSP90 and degradation of its cargo oncoproteins. Flow cytometry studies revealed that both tumor cell lines and normal diploid fibroblasts arrested in the G2/M phase of the cell cycle after Dacinostat treatment. However, an increased sub-G1 population at 48 h (reminiscent of apoptotic cells) was only observed in the cancer cell lines treated with Dacinostat. Dacinostat exhibited antitumor effects in a xenograft animal models. In phase I trials, Dacinostat was well tolerated at doses that induced accumulation of histone acetylation, with higher doses inducing changes consistent with HSP90 inhibition. In another phase 1 in patients with advanced solid tumors, grade 3 or 4 toxicities were observed. Dacinostat had been in phase II clinical trials by Novartis for the treatment of solid tumors but further studies were discontinued.
