What is a piperidine ring?
Piperidine is an organic compound with the molecular formula (CH2)5NH. This heterocyclic amine consists of a six-membered ring containing five methylene bridges (–CH2–) and one amine bridge (–NH–). It is a colorless liquid with an odor described as objectionable, and typical of amines.
Which drugs contain piperidine ring?
Use in pharmaceutical drugs Many pharmaceutical drugs contain a piperidine ring because the group tends to impart pharmacokinetics such as water solubility and bioavailability. Examples of drugs that contain piperidines include mesoridazine, thioridazine, haloperidol, droperidol, PCP, benperidol, and risperidone.
Where does piperidine come from?
Piperidine itself has been obtained from black pepper, from Psilocaulon absimile (Aizoaceae), and in Petrosimonia monandra. The piperidine structural motif is present in numerous natural alkaloids. These include piperine, which gives black pepper its spicy taste. This gave the compound its name.
What are the uses of piperidine?
Piperidine derivatives are being utilized in different ways as anticancer, antiviral, antimalarial, antimicrobial, antifungal, antihypertension, analgesic, anti-inflammatory, anti-Alzheimer, antipsychotic and/or anticoagulant agents.
What is are the roles of piperidine?
Piperidine is an azacycloalkane that is cyclohexane in which one of the carbons is replaced by a nitrogen. It is a metabolite of cadaverine, a polyamine found in the human intestine. It has a role as a reagent, a protic solvent, a base, a catalyst, a plant metabolite, a human metabolite and a non-polar solvent.
What is piperidine made from?
What is piperidine drug?
A derivative of piperidine, astemizole is a long-acting, non-sedative histamine H1-receptor antagonist used for the symptomatic relief of allergic conditions including seasonal allergic rhinitis … From: xPharm: The Comprehensive Pharmacology Reference, 2007.
What does piperidine smell like?
Piperidine is a clear, colorless liquid and has a strong pepper- or amine-like pungent odor (Lewis 1993; Trochimowicz et al. 1994).
Is piperidine an acid or base?
base
Piperidine is the stronger base, with a pKb about 4. The pKb for morpholine would be about 6. In aqueous solution at pH 9, which amine would exist mainly as an ammonium ion? Piperidine remains protonated up to pH about 10.
Why is piperidine a strong base?
But in the piperidine molecule, these lone pairs are present in the sp3 orbitals of the nitrogen, that is, secondary amine and there is no resonance in the ring. This makes it easy for the nitrogen to share its electrons and is highly basic. Therefore, the strongest base is option (D)- piperidine.
