Industrially, piperidine is produced by the hydrogenation of pyridine, usually over a molybdenum disulfide catalyst: C5H5N + 3 H2 → C5H10NH. 5382-16-1, formula is C5H11NO, Name is 4-Piperidinol. Pyridine can also be reduced to piperidine via a modified Birch reduction using sodium in ethanol. Category: piperidines.
Patel, Piyush A.;Bruun, Tanja;Ilina, Polina;Makkyla, Heidi;Lempinen, Antti;Yli-Kauhaluoma, Jari;Tammela, Paivi;Kiuru, Paula S. research published 《 Synthesis and Cytotoxicity Evaluation of Spirocyclic Bromotyrosine Clavatadine C Analogs》, the research content is summarized as follows. Marine-originated spirocyclic bromotyrosines are considered as promising scaffolds for new anticancer drugs. In a continuation of research to develop potent and more selective anticancer compounds, authors synthesized a library of 32 spirocyclic clavatadine analogs by replacing the agmatine, i.e., 4-(aminobutyl)guanidine, side chain with different substituents. These compounds were tested for cytotoxicity against skin cancer using the human melanoma cell line (A-375) and normal human skin fibroblast cell line (Hs27). The highest cytotoxicity against the A-375 cell line was observed for dichloro compound I (CC50 0.4 ± 0.3μM, selectivity index (SI) 2). The variation of selectivity ranged from SI 0.4 to reach 2.4 for the pyridin-2-yl derivative II and hydrazide analog of 2-picoline III. The structure-activity relationships of the compounds in respect to cytotoxicity and selectivity toward cancer cell lines are discussed.
Category: piperidines, 4-Hydroxypiperidine is a molecule with a carbonyl group. It is the most active and selective CCR5 receptor antagonist that has been studied to date. 4-Hydroxypiperidine inhibits HIV infection by preventing the binding of HIV to its receptor on the surface of white blood cells, thereby preventing it from entering these cells. 4-Hydroxypiperidine also acts as an anti-inflammatory agent in chronic bronchitis patients, due to its ability to inhibit prostaglandin synthesis. The chemical ionization mass spectra of this molecule show peaks for methyl ethyl, malic acid, and hydroxyl groups. These properties make 4-hydroxypiperidine a useful candidate for drug development against inflammatory diseases and several cancers.
The molecular structure, vibrational spectra, NBO and UV-spectral analysis of 4-Hydroxypiperidine have been studied. The compounds with a substituted 4-piperidinol core have been found to be potent antagonists of the human H receptor., 5382-16-1.
