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.

Normal phase liquid chromatog. combined with particle beam mass spectrometry has been applied to the anal. of fluconazole, an anti-fungal agent, [2-(2,4-difluorophenyl)-1,3-bis(1H-1,2,4-triazol-1-yl)propan-2-ol] and a related intermediate, UK-51060 [2-(2,4-difluorophenyl)-1-(1H-1,2,4-triazol-1-yl)ethan-2-one]. Electron ionization and chem. ionization have been investigated in combination with quadrupole ion trap and magnetic sector mass spectrometers and the spectra obtained compared with those for direct probe anal. A novel method for the introduction of the chem. ionization reagent gas via the interface is described for particle beam-magnetic sector mass spectrometry. Multi-stage scan routines have been implemented on the ion trap for the selective storage of analyte species and removal of solvent ions. Detection limits for both spectrometers have been determined and are discussed in terms of interface geometry and analyte transport characteristics. Normal phase HPLC on silica provided a good separation of the intermediate from the later eluting fluconazole peak.

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 Synthesis and structure-activity relationships of a novel antifungal agent, ICI 195,739, published in 1988, which mentions a compound: 86404-63-9, Name is 1-(2,4-Difluorophenyl)-2-(1H-1,2,4-triazol-1-yl)ethanone, Molecular C10H7F2N3O, Computed Properties of C10H7F2N3O.

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.

Computed Properties of C10H7F2N3O. The mechanism of aromatic electrophilic substitution of aromatic heterocycles is consistent with that of benzene. Compound: 1-(2,4-Difluorophenyl)-2-(1H-1,2,4-triazol-1-yl)ethanone, is researched, Molecular C10H7F2N3O, CAS is 86404-63-9, about Improved model of lanosterol 14α-demethylase by ligand-supported homology modeling: validation by virtual screening and azole optimization. Author is Sheng, Chunquan; Wang, Wenya; Che, Xiaoying; Dong, Guoqiang; Wang, Shengzheng; Ji, Haitao; Miao, Zhenyuan; Yao, Jianzhong; Zhang, Wannian.

Lanosterol 14α-demethylase (CYP51) is an important target for antifungal drugs. An improved three-dimensional model of CYP51 from Candida albicans (CACYP51) was constructed by ligand-supported homol. modeling and mol. dynamics simulations. The accuracy of the constructed model was evaluated by its performance in a small-scale virtual screen. The results show that known CYP51 inhibitors were efficiently discriminated by the model, and it performed better than our previous CACYP51 model. The active site of CACYP51 was characterized by multiple copy simultaneous search (MCSS) calculations On the basis of the MCSS results, a series of novel azoles were designed and synthesized, and they showed good in vitro antifungal activity with a broad spectrum. The MIC80 value of four of these compounds against C. albicans is 0.001 μg mL-1, indicating that they are promising leads for the discovery of novel antifungal agents.
