Amicibone is an antitussive agent.

Volixibat (SHP626; formerly LUM002) is a potent inhibitor of the apical sodium-dependent bile acid transporter (ASBT) that was developed for the treatment of nonalcoholic steatohepatitis. Volixibat participated in phase II clinical trial to investigate its safety, effectiveness in adults with nonalcoholic steatohepatitis. However, this study was discontinued, without any further explanation for the possible causes. In addition, volixibat was studied in a clinical trial in healthy adults and in patients with type 2 diabetes mellitus, where was shown that the drug was generally well tolerated.

Encenicline (EVP-6124; MT-4666) acts as a potent partial and selective agonist at alpha-7 nicotinic acetylcholine receptor. Encenicline significantly improved memory function in animal models. FORUM Pharmaceuticals (formerly EnVivo Pharmaceuticals) is developing encenicline for the treatment of cognition disorders such as schizophrenia and for Alzheimer's disease.

Bradanicline (formerly known as ATA-101 or TC-5619), a selective full agonist for the alpha7 neuronal nicotinic receptor (NNR) subtype was developed for the treatment of central nervous system diseases and disorders. Bradanicline participated in phase II clinical trials for patients with negative and cognitive symptoms of schizophrenia; however, results did not support a benefit of the drug. The development was also discontinued for Alzheimer's disease and attention-deficit hyperactivity disorder. In addition, it was announced that the first patient had been treated in Phase 2 clinical trial in chronic cough with bradanicline. Phase 2 will test the efficacy and safety of bradanicline in up to 49 patients with refractory chronic cough. Refractory chronic cough is defined as a cough that persists for eight weeks or more. In the plans will conduct additional clinical trials to test the safety and efficacy of bradanicline.

Trodusquemine (MSI-1436) is a "first-in-class" highly selective non-competitive, allosteric inhibitor of PTP1B that can cross the blood-brain barrier to suppress feeding and promote insulin sensitivity and glycemic control. Trodusquemine is a naturally occurring cholestane that can be purified from the liver of the dogfish shark, Squalus acanthias, but it can also be manufactured synthetically by a fairly laborious process that requires several weeks. Trodusquemine has potential hypoglycemic, anti-diabetic, anti-obesity, and antineoplastic activities. Upon administration, trodusquemine selectively targets and inhibits PTP1B, thereby preventing PTP1B-mediated signaling. This prevents the dephosphorylation of the insulin receptor, which improves insulin signaling and insulin sensitivity, and decreases blood glucose levels. In susceptible cancer cells, inhibition of PTP1B causes a reduction of tumor cell proliferation.

Droxicainide is a new antiarrhythmic agent. When given intravenously droxicainide suppressed ouabain-induced arrhythmias in pentobarbital-anesthetized guinea pigs. The initial experimental studies reported that droxicainide appears to have a more potent antiarrhythmic activity and fewer side effects than lidocaine. In local anesthetic tests and following intradermal administration to rabbits, droxicainide produced less local tissue irritation than lidocaine. Droxicainide is a class 1 anti-arrhythmic drug.

IROXANADINE, a pyridine derivative, is under development for the treatment of atherosclerosis and the complications of atherosclerosis such as ischaemic heart disease, peripheral arterial disease, and restenosis. It induces phosphorylation of p38 stress-activated protein kinase, which plays an important role in endothelial cells (EC) homeostasis. EC function plays a central role in vascular diseases.
