Ibutamoren (L-163,191 MK-0677) is a spiropiperidine agonist of the ghrelin receptor and a growth hormone secretagogue. Ibutamoren mimics the actions of growth hormone releasing peptide-6 to increase serum levels of serum insulin-like growth factor-I (IGF-I). Orally active Ibutamoren was being developed by Merck & Co. for a variety of indications, including fibromyalgia, muscle wasting/weakness in patients with chronic kidney disease, Alzheimer's disease and fractures.However, there has been no recent development reported or development has been discontinued for these indications.

Sonepiprazole exhibits highly specific binding to the D4 dopamine receptor with more than 100-fold selectivity for the D4 receptor over other receptors, including dopamine, serotonin, and adrenergic receptors. It is a neutral antagonist at the D4 dopamine receptor and is devoid of dopamine agonist activity. Sonepiprazole selectively induces c-fos expression in the prefrontal cortex and blocks behavioral, biochemical, and genomic effects of repeated amphetamine administration in rats. Sonepiprazole was investigated as an antipsychotic for the treatment of schizophrenia in a placebo-controlled clinical trial, but in contrast to its comparator olanzapine no benefits were found and it was not researched further for this indication.

Ibiglustat (GZ/SAR402671 or Genz-682452) is a small molecule inhibitor of glucosylceramide synthase. Ibiglustat has been demonstrated to effectively lower glycosphingolipid synthesis. Genzyme, a Sanofi Company is developing Ibiglustat for the treatment of Parkinson's Disease, Gaucher Disease, and Fabry Disease.

Aplindore (DAB-452) is a small molecule that displays potent dopamine D2 receptor partial agonist activity in in vitro and in vivo assays and is predicted to have antipsychotic efficacy without motor side effects. Aplindore had been in phase II clinical trials for the treatment of Parkinson's disease and restless legs syndrome. Aplindore was generally well tolerated and there were no withdrawals due to adverse events and no serious adverse events.

Varlitinib (Alternative Names: ARRY-334543; ARRY-543; ASLAN-001; Varlitinib tosylate) is a small molecule based reversible pan-HER inhibitor of EGFR, HER2 and HER4. In response to the binding of various ligands, these kinases undergo heterodimerisation and homodimerization, resulting in activation of numerous growth factor signaling pathways, by inhibiting the activation of the HER receptors via drug, effects such as shrinkage of the tumor and longer survival can be anticipated. In a large variety of cancers, the overexpression and/or constitutive activation of EGFR and HER2 are often observed and frequently correlate with poor clinical prognosis. Licensed from Array BioPharma with global rights for all indications, varlitinib is being developed as first-in-class drug for cholangiocarcinoma, gastric and colorectal cancer, and as best-in-class drug for breast cancer.

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.

Altinicline (SIB-1508Y, SIB-1765F) is a drug which acts as an agonist at neural nicotinic acetylcholine receptors with high selectivity for the α4β2 subtype. It stimulates release of dopamine and acetylcholine in the brain in both rodent and primate models, and progressed as far as Phase II clinical trials for Parkinson's disease, where "no antiparkinsonian or cognitive-enhancing effects were demonstrated", although its current status is unclear.

Tesofensine (also known as NS-2330) is a novel triple monoamine reuptake inhibitor with intrinsic inhibitory activity on norepinephrine (NE), serotonin (5-HT), and dopamine (DA) transporter function. It was development by NeuroSearch as a potential therapy for Alzheimer's disease (AD) and Parkinson's diseases, but these efforts have been discontinued. In phase II clinical trials with tesofensine in obese individuals, dose-related reductions in body weight, body fat and waist circumference, as well as improvements in other obesity-related endocrine factors were observed and the FDA recently endorsed the phase III trial program for this agent.

SU-14813 is an oral, multitargeted tyrosine kinase inhibitor (TKI) targeting vascular endothelial growth factor receptors (VEGFR), platelet-derived growth factor receptors (PDGFR), KIT, and fms-like tyrosine kinase 3 (FLT-3). SU-14813 was developed as a next-generation TKI agent following sunitinib (SU-11248) designed to demonstrate optimized pharmacokinetic (PK) and tolerability profiles. SU14813 demonstrated broad and potent antitumor activity equivalent to that of sunitinib, which resulted in tumor regression, growth arrest, growth delay, and prolonged survival in established xenograft cancer models in mice. A phase II trial of SU-14813 in patients with breast cancer was completed. However, according to the Pfizer pipeline development has been discontinued.
