Targets:
Otenzepad is the first competitive muscarinic M2 antagonist that is cardioselective and had been in phase III clinical trials for the treatment of arrhythmias and bradycardia. Otenzepad was originally developed by Boehringer Ingelheim Pharma KG (Boehringer Ingelheim) in Germany. The parent company is developing oral and IV formulations of the drug for use in symptomatic bradycardia, sinus bradycardia, sick sinus syndrome and symptomatic arrhythmias after intoxication. However, all these research has been discontinued. Otenzepad binds to muscarinic cholinergic receptors in a simple competitive manner. Its affinity for cardiac (M2) muscarinic receptors is about 7 times greater than for ganglionic (M1) receptors and about 36 times greater than for glandular (M3) receptors. The (+)-enantiomer of otenzepad is about 8 times more potent at M2-receptors than the (−)-enantiomer. In a double-blind study, 48 healthy male volunteers were randomised to single oral doses of placebo or otenzepad (120, 240 or 480mg). Heart-rate (HR) was significantly increased by the 250 and 480mg doses (by 15 and 21 beats/minute, respectively). The 480mg dose also increased Diastolic Blood Pressure (DBP) significantly compared with placebo. The oral pharmacokinetics of otenzepad were investigated in a double-blind study in which 48 healthy male volunteers were randomised to single oral doses of placebo or otenzepad (120, 240 or 480mg). Otenzepad bioavailability was 45%, mean residence time (MRT) was 12.5 hours and tmax occurred 2.5 hours postdose.

Rivanicline (also known as RJR-2403 or TC-2403) is a partial neuronal nicotinic acetylcholine receptor agonist. This compound binds primarily to the α4β2 receptor subtype. Rivanicline was originally developed for Alzheimer’s disease and shows pronounced anti-amnesic and increased recognition memory in rats. Because rivanicline also inhibits Interleukin-8 production, it has been further developed as a potential anti-inflammatory treatment for ulcerative colitis (in which nicotine is of therapeutic value but has adverse events). Rivanicline effectively inhibited TNF- and LPS-induced IL-8 production in different cell types, without toxic effects. Rivanicline was also evaluated as a potential compound for the development of nicotinic therapeutics to treat neurological diseases in cases of compromised cholinergic neurotransmission.

Facinicline (MEM-63908 or R-4996) is a selective nicotinic alpha-7 receptor (α7nAChR) partial agonist. It also has properties of a serotonin 3 receptor antagonist. It has hydrochloride form: RG3487 (formerly MEM3454). Facinicline enhances DA efflux by nAChR stimulation, whereas ACh efflux is primarily mediated via 5-HT3 receptor antagonism. It improves cognition and sensorimotor gating in rodents. It has been tested in Alzheimer's disease and cognitive symptoms of schizophrenia.

Vanoxerine, also known as GBR-12909, is a piperazine derivative exhibiting potent selective inhibition of sodium-dependent dopamine reuptake transporters. Vanoxerine has been in clinical trials for Parkinsonism, depression and cocaine addiction but lacked efficacy. Vanoxerine has also been observed as a potent blocker of the following channels: cardiac hERG/IKr potassium channel, Calcium channel, voltage-dependent, L type, alpha 1C subunit (also known as Cav1.2) and voltage-gated sodium channel Nav 1.5. Vanoxerine was studied as a potential treatment for atrial fibrillation. However, phase III clinical trials for this condition were terminated because of cardiac safety concerns. Research also indicates that vanoxerine may have additional mechanisms of action including antagonist action at nicotinic acetylcholine receptors (nAChRs).

Esaprazole, also known as hexaprazole, was developed in the 1980s as a drug for the treatment of gastric and duodenal ulcers. Esaprazole exerts a dose-dependent cytoprotective effect on the gastric mucosa in man. It was shown to have a dose-dependent antisecretory activity, which was particularly evident on secretion volume and acid output. Esaprazole completed phase II clinical trials with only a few minor side effects being reported, but was shown to be less effective than Cimetidine and Ranitidine at healing ulcers. Esaprazole is a weak sigma opioid receptor and muscarinic acetylcholine receptors M3 and M5 ligand. Esaprazole analogs with many compounds showing neuroprotective properties.
