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.

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.

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.

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.
