Application of 86404-63-9. Aromatic compounds can be divided into two categories: single heterocycles and fused heterocycles. Compound: 1-(2,4-Difluorophenyl)-2-(1H-1,2,4-triazol-1-yl)ethanone, is researched, Molecular C10H7F2N3O, CAS is 86404-63-9, about 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.

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.

Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. 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.Formula: C10H7F2N3O.

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.

As far as I know, this compound(86404-63-9)Formula: C10H7F2N3O can be applied in many ways, which is helpful for the development of experiments. Therefore many people are doing relevant researches.

Recommanded Product: 1-(2,4-Difluorophenyl)-2-(1H-1,2,4-triazol-1-yl)ethanone.

The incidence of life-threatening fungal infections is increasing dramatically. In an attempt to develop novel antifungal agents, our previously synthesized phenoxyalkylpiperazine triazole derivatives were used as lead structures for further optimization. By means of structure-based bioisosterism, triazolone was used as a new bioisostere of oxygen atom. This type of bioisosteric replacement can improve the water solubility without loss of hydrogen-bonding interaction with the target enzyme. A series of triazolone-containing triazoles were rationally designed and synthesized. As compared with fluconazole, several compounds showed higher antifungal activity with broader spectrum, suggesting their potential for further evaluations.

Antifungal azole derivatives are known to have potential for inhibition of host P 450 systems, and, in the attempts to increase the antifungal specificity of the inhibitor by identification of extra receptor binding within the enzyme complex, initial synthesis was guided by the structural requirements of the natural lanosterol substrate. With the aid of computer graphics, the 3′-styryl functionality was identified as a key structural element. For metabolically stable systems, in vitro-in vivo correlations exist, but optimizing oral activity resulted in the production of compounds with unacceptably long elimination half-lives. A disconnection of this relationship was achieved in pairs of structural isosteres with metabolic nonequivalence (CN:CONH2/OCH3:OCF3) and led to the identification of ICI 195,739 (I), a novel 3′-tetrafluoropropoxystyryl-substituted bistriazole tertiary alc., as the compound of choice.
