Evenamide (NW-3509) is a blocker of voltage-gated sodium channels. Evenamide modulates sustained repetitive firing, without inducing impairment of normal neuronal excitability. It normalizes glutamate release induced by aberrant sodium channel activity. The potential benefits of the compound have been demonstrated in numerous preclinical models predictive of efficacy in psychiatric diseases, including models of psychosis such as amphetamine-induced hyperactivity, sensorimotor gating and information processing deficits (pre-pulse inhibition impairment induced by different stimuli), mania and depression. Evenamide is being evaluated in a Phase II trial as add-on treatment to 5HT2/D2 blocking antipsychotics in schizophrenic patients.

Dicarbine is an orally active drug approved in Russia under the trade name Карбидин, is used for the treatment patients with schizophrenia and alcoholic psychosis. This drug blocks dopamine receptors in various brain parts, which leads to a reduction in the productive symptoms of psychosis: delusions and hallucinations.

Telupidine (GR53992B), a dihydropyridine derivative is a calcium channel blocker. This is an antihypertensive and cardiovascular agent. Information about the current use of this compound is not available.

Lanicemine is a low-trapping NMDA channel blocker, which was developed by Fisons Pharmaceuticals and later by AstraZeneca for the treatment of the major depressive disorder. The development was terminated in phase II as the drug did not meet the primary endpoint.

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.

Priralfinamide, also known as Ralfinamide, FCE-26742A; NW-1029; PNU-0154339E, is a Na-channel blocker for the treatment of neuropathic pain and other pain conditions such as post-operative dental pain. It has a relatively complex pharmacology, acting as a mixed voltage-gated sodium channel blocker (including Nav1.7), N-type calcium channel blocker, noncompetitive NMDA receptor antagonist, and monoamine oxidase B inhibitor. Priralfinamide is in phase Ⅲ clinical trials by Newron for the treatment of chronic neuropathic pain.

Fostedil (KB-944) is a phosphonic acid derivative with potent vasodilator activity. KB-944 has been demonstrated to produce long lasting coronary vasodilator and hypotensive effects in conscious and anesthetized dogs; increase coronary blood flow in isolated, blood perfused heart preparations of dogs; and reduce systemic pressure in conscious normotensive and hypertensive rats. Slow channel calcium entry blockade is thought to contribute to the vasodilator activity of KB-944. Fostedil is longer acting in hypertensive animals than either nifedipine or diltiazem suggesting a potential clinical advantage for this compound. Unexpectedly, fostedil was shown to produce atrial fibrillation in 3 of 10 hypertensive patients in a placebo controlled study. Fostedil had been in phase II clinical trials for the treatment of angina pectoris. However, this research has been discontinued.

Troxacitabine is a synthetic nucleoside analogue. It is a poor substrate for nucleoside transporters and gains entry into cells by passive diffusion. Intracellular conversion to its active triphosphate form is via deoxycytidine kinase. Incorporation of this metabolite into DNA results in immediate chain termination and apoptosis induction. It is the first nucleoside analog with anticancer activity that has an unnatural stereochemical configuration. The dose-limiting adverse reactions were stomatitis and hand–foot syndrome.

Vincanol is an alkaloid derived from vinca. The drug possesses hypotensive and vasodilating properties which justify its use in cardiovascular therapy. In vitro studies in rats demonstrated that vincanol may act by blocking voltage-gated Na+ channels.

ABT-639 is a T-type calcium (Cav3.2) channel antagonist that was in development with AbbVie for the treatment for pain. ABT-639 is a potent and selective T-type calcium channel blocker. ABT-639 effectively reduces nociceptive and neuropathic pain in rats. ABT-639 produces robust antinociceptive activity in experimental pain models at doses that do not significantly alter psychomotor or hemodynamic function in the rat. ABT-639 blocks recombinant human T-type (Cav3.2) Ca2+ channels in a voltage-dependent fashion (IC50=2 uM) and attenuates low voltage-activated (LVA) currents in rat DRG neurons (IC50=8 uM). ABT-639 was significantly less active at other Ca²⁺ channels (e.g. Ca(v)1.2 and Ca(v)2.2) (IC₅₀ > 30 uM). ABT-639 has high oral bioavailability (%F = 73), low protein binding (88.9%) and a low brain:plasma ratio (0.05:1) in rodents.
