We have synthesized new fluconazole analogs containing two different 1,2,3-triazole units in the side chain. The synthesis of new amide analogs using a variety of acids is also described. All the compounds showed very good antifungal activity. A hemolysis study of the most active compounds I and II showed that both compounds did not cause any hemolysis at the dilutions tested. These compounds did not exhibit any toxicity to L929 cells at MIC and lower concentrations In the docking study, the overall binding mode of I and II appeared to be reasonable and provided a good insight into the structural basis of inhibition of Candida albicans Cyp51 by these compounds

Most of the natural products isolated at present are heterocyclic compounds, so heterocyclic compounds occupy an important position in the research of organic chemistry. A compound: 86404-63-9, is researched, SMILESS is FC1=CC=C(C(CN2N=CN=C2)=O)C(F)=C1, Molecular C10H7F2N3OJournal, Chromatographia called Direct resolution of a new antifungal agent, voriconazole (UK-109,496) and its potential impurities, by use of coupled achiral-chiral high-performance liquid chromatography, Author is Ferretti, R.; Gallinella, B.; La Torre, F.; Zanitti, L., the main research direction is voriconazole resolution HPLC; enantiomer separation voriconazole HPLC.HPLC of Formula: 86404-63-9.

Coupled achiral-chiral high-performance liquid chromatog. (HPLC) with an achiral amino-based column coupled with a chiral amylose-based column was used for qual. and quant. determination of the potential chiral and achiral impurities of voriconazole (UK-109,496), a new antifungal agent with two stereogenic centers. The effect of the organic mobile-phase modifier, ethanol, was studied. The assay response was linearly dependent on concentration over the range 1.2-40.4 μg for voriconazole and 2.5-104.0 ng for the impurities. The limit of detection was 2.5 ng for each analyte.

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.

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.
