4-Piperidinyl compounds

Tirofiban, sold under the brand name Aggrastat, is an antiplatelet medication. It belongs to a class of antiplatelets named glycoprotein IIb/IIIa inhibitors. Tirofiban is a small molecule inhibitor of the protein-protein interaction between fibrinogen and the platelet integrin receptor GP IIb/IIIa and is the first drug candidate whose origins can be traced to a pharmacophore-based virtual screening lead.

Crizotinib, sold under the brand name Xalkori among others, is an anti-cancer medication used for the treatment of non-small cell lung carcinoma (NSCLC). Crizotinib inhibits the c-Met/Hepatocyte growth factor receptor (HGFR) tyrosine kinase, which is involved in the oncogenesis of a number of other histological forms of malignant neoplasms. It also acts as an ALK (anaplastic lymphoma kinase) and ROS1 (c-ros oncogene 1) inhibitor.

Azacyclonol (trade names Ataractan, Calmeran, Frenoton, Frenquel, Psychosan), also known as γ-pipradrol, is a drug which is an ataractive; an agent which diminishes hallucinations in psychotic individuals. It has also been called a tranquilizer and antipsychotic, though these definitions are not accurate as it does not actually possess such properties. Despite being a positional isomer of pipradrol, it is not a psychostimulant, and instead has mild depressant effects.

Immepip is a histamine H3 receptor agonist.

Indalpine, sold under the brand name Upstène, is a selective serotonin reuptake inhibitor (SSRI) that was briefly marketed as an antidepressant for treatment of depression. It was marketed in France and a few other European countries.

chemical compound

Ceritinib (INN, trade name Zykadia ) is a prescription-only drug used for the treatment of non-small cell lung cancer (NSCLC). It was developed by Novartis and received FDA approval for use in April 2014.

Brofaromine (proposed brand name Consonar) is a reversible inhibitor of monoamine oxidase A (RIMA) discovered by Ciba-Geigy. The compound was primarily researched in the treatment of depression and anxiety but its development was dropped before it was brought to market.

Relebactam is a chemical compound used in combination with antibiotics to improve their efficacy. As a beta-lactamase inhibitor, it blocks the ability of bacteria to break down a beta-lactam antibiotic. In the United States, relebactam is approved for use in the combination imipenem/cilastatin/relebactam (Recarbrio by Merck).

Litoxetine (developmental code names SL 81-0385, IXA-001) is an antidepressant which was under clinical development for the treatment of depression in the early 1990s but was never marketed. It acts as a potent serotonin reuptake inhibitor (Ki for = 7 nM) and modest 5-HT3 receptor antagonist (Ki = 315 nM). It has antiemetic activity, and unlike the selective serotonin reuptake inhibitors (SSRIs), appears to have a negligible incidence of nausea and vomiting. The drug is structurally related to indalpine. Development of litoxetine for depression was apparently ceased in the late 1990s

Pipequaline (INN; development code PK-8165) is an anxiolytic drug that was never marketed. It possesses a novel chemical structure that is not closely related to other drugs of this type. The drug has a similar pharmacological profile to the benzodiazepine family of drugs, but with mainly anxiolytic properties and very little sedative, amnestic or anticonvulsant effects, and so is classified as a nonbenzodiazepine anxiolytic.

Tedatioxetine (developmental code name Lu AA24530) is an experimental antidepressant developed by H. Lundbeck A/S for the treatment of major depressive disorder (MDD) and generalized anxiety disorder (GAD). It acts as a triple reuptake inhibitor (TRI) with preference for serotonin and norepinephrine over dopamine, and as an antagonist at 5-HT2A, 5-HT2C, 5-HT3, and α1A-adrenergic receptors. In 2007 Lundbeck and Takeda entered into a partnership that included tedatioxetine but was focused on another, more advanced Lundbeck drug candidate, vortioxetine.

Norfentanyl is an inactive synthetic opioid analgesic drug precursor. It is an analog and metabolite of fentanyl with the removal of the phenethyl moiety (or functional group) from fentanyl chemical structure.

4-Benzylpiperidine is a drug and research chemical used in scientific studies. It has been encountered as a designer drug.
