Prifuroline is a benzofuran derivative patented by French pharmaceutical company Laboratoires Jacques Logeais S. A. As an antiarrhythmic agent. After intravenous administration to pentobarbital-anesthetized dogs, Prifuroline produced a significant dose-related decrease in heart rate and in sinus node recovery time. Prifuroline dose-dependently antagonizes the arrhythmogenic action of aconitine in rats when administered either intravenously or intraduodenally. Prifuroline also diminishes ventricular susceptibility to electrical stimulation in open-chest rats; its effect is comparable to that of disopyramide and amiodarone at the same dose levels. Prifuroline was also able to restore sinus rhythm in guinea-pigs after intracardiac conduction blockade with acetylcholine, although being devoid of anticholinergic activity.

Myfadol is a phenacylpiperidine derivative patented by Tanabe Seiyaku Co., Ltd as low molecular weight non-peptide analgesic. Myfadol produces hot-plate analgesia in rodents with minimal side-effects, and when given parenterally in humans produces analgesia to experimentally-produced and postoperative pain.

Odalasvir (previously known as ACH-3102) is a second-generation inhibitor of the nonstructural protein 5A (NS5A) of hepatitis C virus (HCV). It was reported that HCV NS5A is associated with interferon signaling related to HCV replication and hepatocarcinogenesis. HCV NS5A inhibitors efficiently inhibited HCV replication. It is known that HCV is a leading cause of hepatocellular carcinoma (HCC) in Japan and is one of the major causes of end-stage liver disease, HCC, and liver transplantation in the United States and Europe. Odalasvir completed phase II clinical trial, where was evaluated efficacy and safety of its combinations with AL-335, and simeprevir in the treatment of chronic hepatitis C Infection.

HCI-2084 (wider known as TP-0903) is developing by Tolero Pharmaceuticals for the treatment of different cancers. HCI-2084 is a small molecule AXL receptor tyrosine kinase (RTK) inhibitor. AXL is involved in maintaining a mesenchymal phenotype in cancer cells that enhanced cell survival in stressed environments, and increased resistance to targeted therapies compared to epithelial cells. AXL overexpression has been observed in multiple tumor types that have acquired resistance to various agents. TP-0903 is participating in phase I/II clinical trial in patients with previously treated chronic lymphocytic leukemia (CLL). This study will investigate the safety, pharmacokinetics, pharmacodynamics, and clinical activity of TP-0903. Besides, phase I is currently being conducted in patients with advanced solid tumors in the presence of TP-0903. In addition, TP-0903 was investigated in neuroblastoma (NB) cells, where this drug makes NB cells more vulnerable to the conventional chemotherapeutics.
