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.

Famitinib, an orally active, small molecule, is a tyrosine kinase inhibitor against multiple targets, including vascular endothelial growth factor receptor 2/3, platelet-derived growth factor receptor, and stem cell factor receptor (c-kit). Jiangsu Hengrui Medicine Co is developing famitinib against a wide variety of advanced-stage solid cancers. Famitinib is participating in phase III clinical trials to evaluate its safety and efficacy in patients with advanced colorectal adenocarcinoma. The other phase III clinical trial for patients with non-squamous non-small cell lung cancer was terminated because of the difficulty in recruitment. In addition, the drug is involved in phase II clinical trials for the treatment of cervical cancer, endometrial cancer, fallopian tube cancer, gastrointestinal stromal tumors, nasopharyngeal cancer, and neuroendocrine tumors.

LANEPITANT is a selective nonpeptide antagonist for the neurokinin-1 receptor. It inhibits neurogenic dural inflammation. LANEPITANT was under development as a potential analgesic drug for the treatment of migraine, arthritis and diabetic neuropathy. However, it failed to show sufficient efficacy to support further development.

Ravatirelin is a thiazolyl-alanine derivative patented by Japanese pharmaceutical company Shionogi & Co., Ltd. as a thyrotropin-releasing compound with improved central nerve activating effects such as sustained acetylcholine-releasing effect, and spontaneous motility increasing effect. Rovatirelin binds to the human thyrotropin-releasing hormone receptor with nanomolar affinity and increases the spontaneous firing of action potentials in the acutely isolated noradrenergic neurons of rat locus coeruleus. In in vivo studies, oral administration of Ravatirelin increased both c-Fos expression in the LC and extracellular levels of noradrenaline in the medial prefrontal cortex of rats. Furthermore, Ravatirelin increased locomotor activity. The increase in noradrenaline level and locomotor activity by Ravatirelin was more potent and longer acting than those by taltirelin. In phase I studies in healthy adult males, Ravatirelin exhibited linear pharmacokinetics in a single-ascending dose (0.1 to 10 mg) and a benign safety profile supportive of once-daily oral administration. From results of Phase II and III studies to evaluate the efficacy and safety of Ravatirelin in spinocerebellar degeneration patients, a daily dose of 1.6 to 3.2 mg of Ravatirelin has been considered to be dosage level intended for clinical use as once-daily oral administration.

TrioxBio's API, S-ethylisothiouronium diethylphosphate, MTR-104 (MTR- 105), is a nitric oxide synthase (NOS) inhibitor which blocks the production of nitric oxide, preventing the dilation of blood vessels and the other detrimental effects caused by excessive NOS activity. MTR-105, a fast-acting synthetic NOS inhibitor with rapid onset of action when administered parenterally, has been effective in alleviating hypotension experimentally and in several observational studies while reducing NO production. MTR-105 is registered and approved for clinical use in the Republic of Moldova where data have been collected from 434 patients exposed to the drug in pre- and postapproval clinical investigations.
