Chemistry is traditionally divided into organic and inorganic chemistry. name: N,N-Dimethylpiperidin-4-amine. The former is the study of compounds containing at least one carbon-hydrogen bonds.In a patent，Which mentioned a new discovery about 50533-97-6
A novel series of 2-(6-alkyl-pyrazin-2-yl)-1H-benzo[d]imidazole analogs (3a?3j) derived from 2-(6-chloropyrazin-2-yl)-1H-benzo[d]imidazole (2) by reacting with various substituted cyclic and acyclic secondary amines in presence of Pd-PEPPSI Mes catalyst by using Buchwald?Hartwig amination in excellent yield. The structures of newly synthesized compounds were elucidated by Fourier transform infrared spectroscopy, 1H-nuclear magnetic resonance, 13C-nuclear magnetic resonance, electrospray ionisation mass spectrometry and high-resolution mass spectrometry spectral data. All the title compounds (3a?3j) were evaluated for in vitro screening against cyclooxygenase-1 and cyclooxygenase-2 by colorimetric COX (human ovine) inhibition assay and in vivo anti-inflammatory activity against cyclooxygenase-2 enzyme by means of the carrageenan-induced rat paw edema. The compound 3i was found to have potent anti-inflammatory activity than standard Ibuprofen. The compounds 3a, 3e, and 3j showed appreciable activity against cyclooxygenase-2 enzyme. However the compounds 3a, 3e, 3g, 3h, and 3j were showed maximum activity within 15 to 24 h and 3g and 3i were showed good DPPH scavenging activity. Moreover, the docking studies were also performed and the results are well agreement with the biological data, suggested that compound 3i was a potential anti-inflammatory agent for further development.
Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.name: N,N-Dimethylpiperidin-4-amine, you can also check out more blogs about50533-97-6
