Piperdine

Molfile expand, piperdine. A molecular entity having an available pair of electrons capable of forming a covalent bond with a hydron Br o nsted base or with the vacant orbital of some other molecular entity Lewis base. A substance that increases the rate of a reaction without modifying the overall piperdine Gibbs energy change in the reaction, piperdine.

Piperidine is an organic compound with the molecular formula CH 2 5 NH. This heterocyclic amine consists of a six-membered ring containing five methylene bridges —CH 2 — and one amine bridge —NH—. It is a colorless liquid with an odor described as objectionable, typical of amines. Piperidine was first reported in by the Scottish chemist Thomas Anderson and again, independently, in by the French chemist Auguste Cahours , who named it. Industrially, piperidine is produced by the hydrogenation of pyridine , usually over a molybdenum disulfide catalyst: [12].

Piperidines are among the most important synthetic fragments for designing drugs and play a significant role in the pharmaceutical industry. Their derivatives are present in more than twenty classes of pharmaceuticals, as well as alkaloids. The current review summarizes recent scientific literature on intra- and intermolecular reactions leading to the formation of various piperidine derivatives: substituted piperidines, spiropiperidines, condensed piperidines, and piperidinones. Moreover, the pharmaceutical applications of synthetic and natural piperidines were covered, as well as the latest scientific advances in the discovery and biological evaluation of potential drugs containing piperidine moiety.

Piperine and piperidine are the two major alkaloids extracted from black pepper Piper nigrum ; piperidine is a heterocyclic moiety that has the molecular formula CH 2 5 NH. Over the years, many therapeutic properties including anticancer potential of these two compounds have been observed. Piperine has therapeutic potential against cancers such as breast cancer, ovarian cancer, gastric cancer, gliomal cancer, lung cancer, oral squamous, chronic pancreatitis, prostate cancer, rectal cancer, cervical cancer, and leukemia. Whereas, piperidine acts as a potential clinical agent against cancers, such as breast cancer, prostate cancer, colon cancer, lung cancer, and ovarian cancer, when treated alone or in combination with some novel drugs. Both of these phytochemicals lead to inhibition of cell migration and help in cell cycle arrest to inhibit survivability of cancer cells.
