In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Preparation and adsorption properties of Ni(II) ion-imprinted polymers based on synthesized novel functional monomer, published in 2021, which mentions a compound: 86404-63-9, Name is 1-(2,4-Difluorophenyl)-2-(1H-1,2,4-triazol-1-yl)ethanone, Molecular C10H7F2N3O, Quality Control of 1-(2,4-Difluorophenyl)-2-(1H-1,2,4-triazol-1-yl)ethanone.

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.

Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 86404-63-9, is researched, Molecular C10H7F2N3O, about Development and validation of a liquid chromatographic method for the stability study of a pharmaceutical formulation containing voriconazole using cellulose tris(4-chloro-3-methylphenylcarbamate) as chiral selector and polar organic mobile phases, the main research direction is liquid chromatog voriconazole cellulose chloromethylphenylcarbamate chiral selector; Chiral stability; Chiral stationary phase; Liquid chromatography; Validation; Voriconazole.Computed Properties of C10H7F2N3O.

The ophthalmic solution of voriconazole, i.e. (2R,3S)-2-(2,4-difluorophenyl)-3-(5-fluoropyrimidin-4-yl)-1-(1H-1,2,4-triazol-1-yl)butan-2-ol, made from an injection formulation which also contains sulfobutylether-β-cyclodextrin sodium salt as an excipient (Vfend), is used for the treatment of fungal keratitis. A liquid chromatog. (LC) method using polar organic mobile phase and cellulose tris(4-chloro-3-methylphenylcarbamate) coated on silica as chiral stationary phase was successfully developed to evaluate the chiral stability of the ophthalmic solution The percentage of methanol (MeOH) in the mobile phase containing acetonitrile (ACN) as the main solvent significantly influenced the retention and resolution of voriconazole and its enantiomer ((2S,3R)-2-(2,4-difluorophenyl)-3-(5-fluoropyrimidin-4-yl)-1-(1H-1,2,4-triazol-1-yl)butan-2-ol). The optimized mobile phase consisted of ACN/MeOH/diethylamine/trifluoroacetic acid (80/20/0.1/0.1; volume/volume/volume/volume). The method was found to be selective not only regarding the enantiomer of voriconazole but also regarding the specified impurities described in the monograph from the European Pharmacopoeia. The LC method was then fully validated applying the strategy based on total measurement error and accuracy profiles. Under the selected conditions, the determination of 0.1% of voriconazole enantiomer could be performed. Finally, a stability study of the ophthalmic solution was conducted using the validated LC method.

Safety of 1-(2,4-Difluorophenyl)-2-(1H-1,2,4-triazol-1-yl)ethanone. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. 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. Author is Miletic, Tijana; Kyriakos, Kachrimanis; Graovac, Adrijana; Ibric, Svetlana.

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.

Reference of 6-Methylnicotinic acid. The fused heterocycle is formed by combining a benzene ring with a single heterocycle, or two or more single heterocycles. Compound: 6-Methylnicotinic acid, is researched, Molecular C7H7NO2, CAS is 3222-47-7, about Catalytic deoxygenative coupling of aromatic esters with organo-phosphorus compounds. Author is Kurosawa, Miki B.; Isshiki, Ryota; Muto, Kei; Yamaguchi, Junichiro.

We have developed a deoxygenative coupling of aromatic esters with diarylphosphine oxides/dialkyl phosphonates under palladium catalysis. Reaction of Ph aromatic esters ArCO2Ph with hydrophosphoryl compounds HP(O)R2 (R = Ph, aryl, BuO) in the presence of PdCl2/dcype and HCO2Na reductant afforded benzyl phosphine oxides, phosphonates and phosphinates ArCH2P(O)R2. In this reaction, aromatic esters can work as novel benzylation reagents to give the corresponding benzylic phosphorus compounds The key of this reaction is the use of Ph esters, an electron-rich diphosphine as a ligand, and sodium formate as a hydrogen source. Arylcarboxylic acids were also applicable in this reaction using (Boc)2O as an additive. Palladium/dcype worked as a bifunctional catalyst to activate the acyl C-O bond of the ester and to support the reduction with sodium formate.

SDS of cas: 86404-63-9. 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 Synthesis and structure-activity relationships of a novel antifungal agent, ICI 195,739.

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.

Voriconazole is a new triazole antifungal agent with potent, wide-spectrum activity. Its pharmacokinetics and metabolism have been studied in mouse, rat, rabbit, dog, guinea pig, and humans after single and multiple administration by both oral and i.v. routes. Absorption of voriconazole is essentially complete in all species. The elimination of voriconazole is characterized by non-linear pharmacokinetics in all species. Consequently, pharmacokinetic parameters are dependent upon dose, and a superproportional increase in area under the curve is seen with increasing dose in rat and dog toxicol. studies. Following multiple administration, there is a decrease in systemic exposure. This is most pronounced in mouse and rat, less so in dog, and not observed in guinea pig or rabbit. Repeat-dose toxicol. studies in mouse, rat, and dog have demonstrated that induction of cytochrome P 450 by voriconazole (autoinduction of metabolism) is responsible for the decreased exposure in these species. Autoinduction of metabolism is not observed in humans, and plasma steady-state concentrations remain constant with time. Voriconazole is extensively metabolized in all species. The major pathways in humans involve fluoropyrimidine N-oxidation, fluoropyrimidine hydroxylation, and Me hydroxylation. Also, N-oxidation facilitates cleavage of the mol., resulting in loss of the fluoropyrimidine moiety and subsequent conjugation with glucuronic acid. Major pathways are represented in animal species. The major circulating metabolite in rat, dog, and human is the N-oxide of voriconazole. It is not thought to contribute to efficacy since it is at least 100-fold less potent than voriconazole against fungal pathogens in vitro.
