Imidafenacin (INN) is a urinary antispasmodic of the anticholinergic class. Pharmacol: [1]
Thioridazine is a first generation antipsychotic drug belonging to the phenothiazine drug group and was previously widely used in the treatment of schizophrenia and psychosis. The branded product was withdrawn worldwide in 2005 because it caused severe cardiac arrhythmias. However, generic versions are still available in the US.
In stereochemistry, a chiral auxiliary is a stereogenic group or unit that is temporarily incorporated into an organic compound in order to control the stereochemical outcome of the synthesis. The chirality present in the auxiliary can bias the stereoselectivity of one or more subsequent reactions. The auxiliary can then be typically recovered for future use.
Arecoline is a nicotinic acid-based mild parasympathomimetic stimulant alkaloid found in the areca nut, the fruit of the areca palm. It is an odourless oily liquid. It can bring a sense of enhanced alertness and energy, euphoria and relaxation. The psychoactive effects are comparable to that of nicotine.
Piritramide(R-3365, trade names Dipidolor, Piridolan, Pirium and others) is a synthetic opioid analgesic that is marketed in certain European countries including: Austria, Belgium, Czech Republic, Slovenia, Germany and the Netherlands. It comes in free form, is about 0.75x times as potent as morphine and is given parenterally for the treatment of severe pain. Nausea, vomiting, respiratory depression and constipation are believed to be less frequent with piritramide than with morphine, and it produces more rapid-onset analgesia when compared to morphine and pethidine. After intravenous administration the onset of analgesia is as little as 1–2 minutes, which may be related to its great lipophilicity. The analgesic and sedative effects of piritramide are believed to be potentiated with phenothiazines and its emetic (nausea/vomiting-inducing) effects are suppressed. The volume of distribution is 0.7-1 L/kg after a single dose, 4.7-6 L/kg after steady-state concentrations are achieved and up to 11.1 L/kg after prolonged dosing.
Bifeprunox (INN) (code name DU-127,090) is an atypical antipsychotic which, similarly to aripiprazole, combines minimal D2 receptor agonism with serotonin receptor agonism. It was under development for the treatment of schizophrenia but has since been abandoned.
Cloperastine (INN) or cloperastin, in the forms of cloperastine hydrochloride (JAN) and cloperastine fendizoate, is an antitussive and antihistamine that is marketed as a cough suppressant in Japan, Hong Kong, and in some European countries. It was first introduced in 1972 in Japan, and then in Italy in 1981.
Linopirdine is a putative cognition-enhancing drug with a novel mechanism of action. Linopirdine blocks the KCNQ2\3 heteromer M current with an IC50 of 2.4 micromolar disinhibiting acetylcholine release, and increasing hippocampal CA3-schaffer collateral mediated glutamate release onto CA1 pyramidal neurons. In a murine model linopirdine is able to nearly completely reverse the senescence-related decline in cortical c-FOS, an effect which is blocked by atropine and MK-801, suggesting Linopirdine can compensate for the age related decline in acetylcholine release. Linopirdine also blocks homomeric KCNQ1 and KCNQ4 voltage gated potassium channels which contribute to vascular tone with substantially less selectivity than KCNQ2/3. Linopirdine also acts as a glycine receptor antagonist in concentrations typical for Kv7 studies in the brain.
Budipine is an antiparkinson agent marketed for the treatment of Parkinson's disease.
Tandospirone is an anxiolytic and antidepressant drug used in China and Japan, where it is marketed by Dainippon Sumitomo Pharma. It is a member of the azapirone class of drugs and is closely related to other azapirones like buspirone and gepirone.
Ramatroban (INN) is a thromboxane receptor antagonist.
Talipexole is a dopamine agonist that is marketed as a treatment for Parkinson's Disease in Japan by Boehringer Ingelheim; it was introduced in 1996. As of December 2014 it was not approved for marketing in the US nor in Europe.
Monatepil is a calcium channel blocker and α1-adrenergic receptor antagonist used as an antihypertensive.
Pipotiazine (Piportil), also known as pipothiazine, is a typical antipsychotic of the phenothiazine class used in the United Kingdom and other countries for the treatment of schizophrenia. Its properties are similar to those of chlorpromazine. A 2004 systematic review investigated its efficacy for people with schizophrenia:
Igmesine (JO-1,784) is a sigma receptor agonist (IC50 = 39 nM (rat brain)). It has neuroprotective and antidepressant-like effects in animal studies, as well as nootropic effects in models of age-related cognitive decline. In two phase II clinical trials, igmesine was found to be effective in the treatment of depression and was as active as the comparator fluoxetine. However, in a large phase III clinical trial, igmesine failed to show significant effectiveness for depression. The drug has not been developed further.
Tazomeline (LY-287,041) is a drug which acts as a non-selective muscarinic acetylcholine receptor agonist. It was in clinical trials for the treatment of cognitive dysfunction such as that seen in Alzheimer's disease and schizophrenia, but development was apparently scrapped for unknown reasons. Another of the patented uses is for the treatment of "severe painful conditions".
Mazapertine (RWJ-37796) is an antipsychotic agent that was developed by Johnson & Johnson but never marketed. It exerts its pharmacological effect through affinity for dopamine D2, serotonin 5-HT1A, and α1-adrenergic receptors.
Ciprefadol is an opioid analgesic that is an isoquinoline derivative most closely related to cyclazocine and picenadol, with a number of other related compounds known. Ciprefadol is a mixed agonist–antagonist at μ-opioid receptors and can partly block the effects of morphine at low doses, though at higher doses it acts more like a full agonist. It is also a potent κ-opioid agonist, unlike the corresponding N-methyl and N-phenethyl derivatives which are reasonably μ-selective agonists.
NE-100 or 4-methoxy-3-(2-phenylethoxy)-N,N-dipropylbenzeneethanamine is a selective sigma-1 receptor antagonist, with a reported binding affinity of Ki = 1.03 ± 0.01 nM, and more than 205 times selectivity over the sigma-2 receptor.
Lomerizine (INN) is a diphenylpiperazine class L-type and T-type calcium channel blocker. This drug is currently used clinically for the treatment of migraines, while also being used experimentally for the treatment of glaucoma and optic nerve injury.
Vibegron, sold under the brand name Gemtesa, is a medication for the treatment of overactive bladder. Vibegron is a selective beta-3 adrenergic receptor agonist.
