Moxaprindine is a antiarrhythmic drug for the treatment of ventricular arrhythmias patented by Manufacture de Produits Pharmaceutiques A. Christiaens, S. A. In clinical studies Moxaprindine shows high efficacy in suppressing ventricular arrhythmias occurring before, during and after maximal exercise stress testing. This effect was obtained both in subjects with clinically normal hearts and in a limited number of patients with ischemic heart disease.

FENPYROXIMATE is a pyrazole acaricide widely used in the prevention of acarids (mites) in fruit plant gardens. It is a potent inhibitor of the mitochondrial proton-translocating NADH-quinone oxidoreductase (complex I).

Rabeximod is an indolo[2,3-b]quinoxaline derivative patented by OxyPharma AB as anti-inflammatory agent useful for the treatment of autoimmune disease. Rabeximod impaired monocyte differentiation into monocyte-derived dendritic cells and pro-inflammatory allostimulated macrophages. Monocyte-derived dendritic cells that were treated with Rabeximod resulted in a significant decrease in their ability to pinocytose antigens, while no effect was exerted by the drug on the ability of allostimulated macrophages and anti-inflammatory macrophages to phagocytose. Rabeximod reduces the severity of arthritis in rodent models of rheumatoid arthritis and multiple sclerosis. Rabeximod efficiently prevented arthritis during the time window when TLR2 or TLR4 ligands activate inflammatory macrophages.

Raxatrigine also known as GSK1014802 and CNV-1014802, is a novel analgesic under development by Convergence Pharmaceuticals for the treatment of lumbosacral radiculopathy (sciatica) and trigeminal neuralgia (TGN). It is a novel state dependent small molecule sodium channel blocker that preferentially inhibits the Nav 1.7 ion channel, a therapeutic target implicated by genetics in human pain conditions. Raxatrigine is thought to penetrate the central nervous system and block Nav channels in a novel manner. CNV1014802 was granted orphan drug designation in 2013 by the US Food and Drug Administration (FDA) for the treatment of trigeminal neuralgia.

Soterenol [(+)-1-(3-methanesulphonamido, 4-hydroxyphenyl)-2-isopropylaminoethanol, MJ 1992] is a directly acting sympathomimetic amine which has been shown to display Beta2-adrenoceptor selectivity. Soterenol, a methanesulfonamido-phenethanolamine related structurally to isoproterenol, was a highly effective bronchodilator agent in several animal species by various routes of administration. The bronchodilator potency of soterenol was equivalent to, or greater than, that of isoproterenol. Soterenol also had potent stimulant action on the alpha-receptor of the smooth muscle.

Ameltolide (ADD 75073, LY 201116) is a 4-aminobenzamide anticonvulsant patented by Research Corporation Technologies in the USA. Ameltolide is a sodium channel antagonist, it represents a potential therapy for the treatment of epilepsy. Ameltolide had been in phase I clinical trials by Research Corporation Technologies for the treatment of epilepsy. However, this research has been discontinued.

Suricainide (also known as AHR 10718) is an aminoalkylurea derivative patented by A. H. Robins Co., Inc. as an antiarrhythmic agent. Suricainide induces a use-dependent decrease in Vmax and significantly decreased Purkinje fiber conduction velocity and action potential duration. Suricainide had no effect on slow response action potentials induced by isoproterenol but ventricular muscle action potentials were significantly prolonged by Suricainide. Suricainide significantly decreased normal automaticity, catecholamine-enhanced automaticity, and abnormal automaticity induced by barium or myocardial infarction. In preclinical modes, Suricainide suppresses the aconitine-induced canine atrial arrhythmia.

Cizolirtine is a potent analgesic in mice and rats, with an efficacy superior to that of aspirin and other nonsteroid anti-inflammatory drugs. Recent studies have shown that the analgesic effect of cizolirtine could be related, at least partially, to an inhibition of spinal substance P and calcitonin gene-related peptide release. Cizolirtine has been in clinical trials for the treatment of pain and overactive bladder. Reported adverse events are: dry mouth, dizziness, nausea, vomiting, blurred vision.
