In this study, a novel functional monomer N-(1-(2,4-difluorophenyl)-2-(1H-1,2,4-triazol-1-yl)ethyl)acrylamide (NDTEA) was designed and synthesized, and was used to prepare Ni(II) ion-imprinted polymers (Ni(II)-IIPs). Sixteen kinds of Ni(II)-IIP (Ni(II)-IIP1 – 16) and corresponding non-imprinted polymers (NIP1 – 16) were prepared by precipitation polymerization method. After optimized condition experiment, Ni(II)-IIP5 possessed maximum adsorption capacity and better imprinting factor under optimal exptl. conditions which indicated by equilibrium adsorption experiments The morphol. and structural characteristics of Ni(II)-IIP5 were characterized by SEM and Brunauer-Emmett-Teller (BET). The adsorption selectivity of Ni(II)-IIP5 was analyzed by ICP-OES, and the results showed that Ni(II)-IIP5 had favorable selectivity recognition ability for Ni(II) when Cu(II), Co(II), and Cd(II) are used as competitive ions. The kinetic experiment indicated that the performance of Ni(II) adsorption on the surface of Ni(II)-IIP5 obeyed the pseudo-first-order model, and adsorption equilibrium was attained after 15 min. Isothermal adsorption process fitted to Langmuir and Freundlich isothermal adsorption models, simultaneously. The results showed that Ni(II)-IIP5 prepared by using a new functional monomer had better permeation selectivity and higher affinity for Ni(II), which also verified the rationality of the functional monomer design. At the same time, it also provided a broad application prospect for removal of Ni(II) in complex samples.

Reference of 1-(2,4-Difluorophenyl)-2-(1H-1,2,4-triazol-1-yl)ethanone. So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic. Compound: 1-(2,4-Difluorophenyl)-2-(1H-1,2,4-triazol-1-yl)ethanone, is researched, Molecular C10H7F2N3O, CAS is 86404-63-9, about Spray-dried voriconazole-cyclodextrin complexes: Solubility, dissolution rate and chemical stability.

The present work investigates the effect of complexation with hydroxypropyl-beta-cyclodextrin (HPBCD) and 2-O-methyl-beta-cyclodextrin (2-O-MBCD), on voriconazole solubility, dissolution rate and chem. stability. Drug-cyclodextrin complexes were prepared as aqueous solutions, which were spray-dried, and their properties were compared to wet ground samples and phys. mixtures DSC anal. revealed absence of crystalline voriconazole from spray-dried complexes. FTIR spectroscopy indicated changes in the H-bonding network of the hydroxyl groups of cyclodextrin following drug inclusion. Dissolution rate of voriconazole was significantly higher from spray-dried complexes with either cyclodextrin in comparison with free drug, phys. mixtures, or wet ground mixtures However, two degradation impurities were found in aged samples, with slightly higher impurity level with HPBCD. Performed solubility studies suggested that 2-O-MBCD is more efficient solubilizer. Mol. docking simulations showed a difference in the 1:1 binding affinities and sites, with HPBCD surprisingly forming complexes of much lower energy, thus suggesting a multiple rather than a 1:1 complexation.

A compound: 86404-63-9, is researched, SMILESS is FC1=CC=C(C(CN2N=CN=C2)=O)C(F)=C1, Molecular C10H7F2N3OJournal, Article, Research Support, Non-U.S. Gov’t, European Journal of Medicinal Chemistry called Design, synthesis, and biological evaluation of novel triazole derivatives as inhibitors of cytochrome P450 14α-demethylase, Author is Chai, Xiaoyun; Zhang, Jun; Hu, Honggang; Yu, Shichong; Sun, Qingyan; Dan, Zhigang; Jiang, Yuanying; Wu, Qiuye, the main research direction is triazole preparation cytochrome P 450 14 alpha demethylase inhibitor; mol modeling triazole cytochrome P 450 14 alpha demethylase.Application In Synthesis of 1-(2,4-Difluorophenyl)-2-(1H-1,2,4-triazol-1-yl)ethanone.

Based on the results of computational docking to the active site of the cytochrome P 450 14α-demethylase (CYP51), a series of 1-(1H-1,2,4-triazole-1-yl)-2-(2,4-difluorophenyl)-3-substituted-2-propanols I (R = H, 2-F, 2,4-Cl2, 4-MeO2C, PhO2C, etc.) as analogs of fluconazole were designed, synthesized, and evaluated as antifungal agents. The MIC80 values indicate that compounds I (R = H, 2-F, 4-Me, etc.) exhibited higher activity against nearly all fungi tested except Aspergillus fumigatus than fluconazole, while I (R = COOR1, R1 = Me, Et, iso-Pr, COOAr, etc.; Ar = Ph, 3-O2NC6H4, 4-ClC6H4, 2-MeO2CC6H4, etc.) showed no activity or only moderate activity against all fungi tested. Noticeably, the MIC value of I (R = H, 2-F, 4-Cl) is 64 times lower than that of fluconazole against Microsporum gypseum in vitro. And I (R = H, 2-F, CO2Et) showed 128 times higher activity (with the MIC80 value of 0.0039 μg/mL) than that of fluconazole against Candida albicans and also showed higher activity than that of the other pos. controls. Computational docking experiments indicated that the inhibition of CYP51 involves a coordination bond with iron of the heme group, the hydrophilic H-bonding region, the hydrophobic region, and the narrow hydrophobic cleft. In addition, the activity of the compounds would be enhanced when the side chains were shorter.

The catalytic, enantioselective N-oxidation of substituted pyridines is described. The approach is predicated on a biomol.-inspired catalytic cycle wherein high levels of asym. induction are provided by aspartic acid-containing peptides as the aspartyl side chain shuttles between free acid and peracid forms. Desymmetrizations of bis(pyridine) substrates bearing a remote pro-stereogenic center are demonstrated, presenting a new entry into chiral pyridine frameworks in a heterocycle-rich mol. environment. Representative functionalizations of the enantioenriched pyridine N-oxides further document the utility of this approach. Demonstration of the asym. N-oxidation in two venerable drug-like scaffolds, Loratadine and Varenicline, show the likely generality of the method for highly variable and distinct chiral environments, while also revealing that the approach is applicable to both pyridines and 1,4-pyrazines.
