Reference of 1-(Bis(4-chlorophenyl)methyl)piperazine. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: 1-(Bis(4-chlorophenyl)methyl)piperazine, is researched, Molecular C17H18Cl2N2, CAS is 27469-61-0, about Validation of Model of Cytochrome P450 2D6: An in Silico Tool for Predicting Metabolism and Inhibition. Author is Kemp, Carol A.; Flanagan, Jack U.; van Eldik, Annamaria J.; Marechal, Jean-Didier; Wolf, C. Roland; Roberts, Gordon C. K.; Paine, Mark J. I.; Sutcliffe, Michael J..

There has been much interest in the development of a predictive model of cytochrome P 450 2D6 particularly because this enzyme is involved in the oxidation of at least 50 drugs. Previously we have described the combined use of homol. modeling and mol. docking to correctly position a range of substrates in the CYP2D6 active site with the known sites of metabolism above the heme. Here, our approach identifies correctly the site of metabolism of the atypical (no basic nitrogen) cytochrome P 450 2D6 substrate, spirosulfonamide. The same method is used to screen a small compound database for cytochrome P 450 2D6 inhibition. A database containing 33 compounds from the National Cancer Institute database was docked into our cytochrome P 450 2D6 homol. model using the program GOLDv2.0. Exptl. IC50 values for the 33 compounds were determined; comparison with the corresponding docked scores revealed a correlation with a regression coefficient of r2 = 0.61 (q2 = 0.59). The method was able to discriminate between tight and weak binding compounds and correctly identified several novel inhibitors. The results therefore suggest that our approach, which combines homol. modeling with mol. docking, has produced a useful predictive in silico tool for cytochrome P 450 2D6 inhibition, which is best used as one filter in a multifilter database screen.

Safety of 2-Chloro-1,3-bis(2,6-diisopropylphenyl)-1H-imidazol-3-ium chloride. The mechanism of aromatic electrophilic substitution of aromatic heterocycles is consistent with that of benzene. Compound: 2-Chloro-1,3-bis(2,6-diisopropylphenyl)-1H-imidazol-3-ium chloride, is researched, Molecular C27H36Cl2N2, CAS is 1228185-09-8, about Norbornene polymerization and copolymerization with 1-alkenes by neutral palladium complexes bearing aryloxide imidazolin-2-imine ligand. Author is Li, Mingyuan; Zhang, Hu; Cai, Zhengguo; Eisen, Moris S..

A series of novel aryloxide imidazolin-2-imine bidentate neutral Pd(II) complexes with different substituents on the imidazolin-2-imine ligand were synthesized and characterized. In the single crystal X-ray diffraction anal., the complexes Pd1 and Pd2 adopted almost square-planar geometries, while Pd3 bearing the bulkier 2,6-bis(diphenylmethyl)-4-methylphenyl substituent was obtained as the allyl adducted base-free η3 coordination mode. In the presence of very low EtAlCl2 loadings (100 equivalent), these Pd(II) complexes exhibited high activity (∼106 g mol-1 h-1) and good thermal stability (up to 100°C) toward the addition polymerization of norbornene. Most importantly, these Pd(II) catalysts were able to promote the copolymerization of norbornene with 1-dodecene and 1-octadecene with high activity (>105 g mol-1 h-1) to yield high-mol.-weight (Mn up to 5.59 x 104 g mol-1) copolymers. The 1-alkene incorporation of resulting copolymers was modulated in a wide range (5.1-15.3%) by changing the comonomer feed ratio, accompanied by the control of the glass transition temperature (Tg = 231.6-309.6°C). These complexes are rare examples of neutral Pd(II) complexes toward the efficient synthesis of norbornene-based cyclic olefin copolymers (COCs).
