DFT calculations have shown that the N-O dipole of benzene- and naphthalene-fused 1,2-oxazole N-oxides causes a distortion of their sigma and pi frame, concentrated on the 1,2-oxazole ring, such that it increases its susceptibility to opening. The distortion forces the benzene ring into some diene geometry, thus, reducing pi delocalization over the bi- or tricyclic structure and ultimately their aromatic character. C-3 substitution has a marked influence mainly on the naphthalene-fused N-oxides. C-5 and particularly C-6 substitution, as the position of most extended interaction with the N-O dipole through the pi ring density, contribute to the distortion of the 1,2-oxazole geometry and thereby to the decrease of aromaticity of the structure. Bond uniformity (I (A)), average bond order (ABO) and Harmonic Oscillator Model of Aromaticity (HOMA) indices have been recruited to measure aromaticity changes. I (A) and ABO appear to be more credible to 1,2-benzoxazole N-oxides and 1,2-naphthoxazole N-oxides, respectively, while HOMA has been found equally reliable to both. Hardness and dipole moments follow similar trends. Energies, localization and separation of the four frontiers orbitals, i.e. HO, HO-1, and LU, LU+1, indicate a rather notable aromatic character of the N-oxides. Their reactivity profile, portrayed by descriptors such as Fukui and electro(nucleo)philicity Parr functions, shows good agreement with experimental outcomes towards electrophiles but succumbs to discrepancies towards nucleophiles due to the susceptibility of the hetero-ring to opening. The push-pull character of the N-O dipole and more importantly the extent of its double bonding direct site selectivity.

Zonisamide (ZNS; 3-sulfamoylmethyl-1,2-benzisoxazole), as one of the newer antiepileptic drugs, has been demonstrated its broad-spectrum clinical efficacy on various neuropsychiatric disorders. However, little is known regarding the mechanism of ZNS actions on ion currents in neurons. We thus investigated its effect on ion currents in differentiated hippocampal 19-7 cells. In whole-cell configuration of patch-clamp technology, the ZNS (30 mu M) reversibly increased the amplitude of K+ outward currents, and paxilline (1 mu M) was effective in suppressing the ZNS-induced increase of K+ outward currents. In inside-out configuration, ZNS (30 mu M) applied to the intracellular face of the membrane did not alter single-channel conductance; however, it did enhance the activity of large-conductance Ca2+-activated K+ (BKCa) channels primarily by decreasing mean closed time. In addition, the EC50 value for ZNS-stimulated BK Ca channels was 34 mu M. This drug caused a left shift in the activation curve of BK Ca channels, with no change in the gating charge of these channels. Moreover, ZNS at a concentration greater than 100 mu M also reduced the amplitude of A-type K+ current in these cells. A simulation modeling based on hippocampal CA3 pyramidal neurons (Pinsky-Rinzel model) was also analyzed to investigate the inhibitory effect of ZNS on the firing of simulated action potentials. Taken together, this study suggests that, in hippocampal neurons during the exposure to ZNS, the ZNS-mediated effects on BK Ca channels and A-type K+ current could be potential mechanisms through which it affects neuronal excitability.

Zonisamide (1,2-benzisoxazole-3-methanesulfonamide) an anticonvulsant agent, is primarily metabolized to 2-sulfamoylacetyl-phenol by reductive cleavage of the 1,2-benzisoxazole ring. Rabbit liver cytosol with an electron donor of aldehyde oxidase exhibited a significant zonisamide reductase activity that was sensitive to inhibition by menadione, an inhibitor of aldehyde oxidase, The result suggested that the cytosolic activity is caused by aldehyde oxidase, a cytosolic enzyme. In fact, rabbit and rat liver aldehyde oxidase had the ability to reduce zonisamide when supplemented with its electron donor, Apparent K-M and V-max values of aldehyde oxidase for zonisamide were 217 mu M and 42 nmol/10 min/mg protein in the case of the rabbit liver enzyme, and 542 mu M and 382 nmol/10 min/mg protein in the case of the rat liver enzyme, respectively. In rabbits, hamsters, mice, and guinea pigs, zonisamide reductase activity of the liver cytosols with 2-hydroxypyrimidine, an electron donor of aldehyde oxidase, was much higher than that of the liver microsomes with NADPH. In rats, zonisamide reductase activity was examined with liver microsomes and cytosols from seven strains. The 2-hydroxypyrimidine-dependent cytosolic activity exhibited marked strain differences, unlike the NADPH-dependent microsomal activity, 1,2-Benzisoxazole was also reduced to salicylaldehyde by rabbit liver cytosol and aldehyde oxidase in the presence of 2-hydroxypyrimidine, Stoichiometric studies showed that 2-sulfamoylacetylphenol was formed accompanying nearly equimolar ammonia from zonisamide.

CONSPECTUS: We describe here a family of coordination cages with interesting structural, guest-binding, and catalytic properties. Flexible bridging ligands containing two bidentate pyrazolylpyridine termini assemble with transition-metal dications to afford coordination cages containing a metal ion at each vertex, a bridging ligand spanning each edge, and a 2:3 metal:ligand ratio. This stoichiometry is expressed in structures ranging from M4L6 tetrahedra to M16L24 tetracapped truncated tetrahedra, which are stabilized by the formation of pi-stacked arrays between electron-rich and electron-poor ligand segments that form around the cage periphery. In some cases concentration- and/or temperature-dependent equilibria between multiple cage structures occur, arising from a balance between entropy, which favors the formation of a larger number of smaller assemblies, and enthalpy, which maximizes both interligand aromatic stacking and solvophobic effects in the larger assembles. The cages are hollow and can accommodate guests often anions or solvent molecules in the central cavity. For one cage family, M8L12 species with an approximately cubic structure and a ca. 400 angstrom(3) cavity, the guest binding properties have been studied extensively. This cage can accommodate a wide range of neutral organic guests, with binding in water being driven principally by the hydrophobic effect, which leads to binding constants of up to 10(8) W-1. The accumulation of a large amount of empirical data on guest binding in the M8L12 cage in water provided the basis for a predictive tool for in silico screening of potential guests using the molecular docking program GOLD; this methodology has allowed the identification of numerous new guests with accurately predicted binding constants and provides a transformative new approach to exploring the host/guest chemistry of cages. Binding of benzisoxazole inside the M8L12 cage results in substantial rate enhancements by a factor of up to 2 x 10(3) -of the Kemp elimination, in which benzisoxazole reacts to give 2-cyanophenolate. Catalysis arises because the 16+ cage cation accumulates anions around the surface by ion pairing, leading to a high effective concentration of hydroxide ions surrounding the guest even when the bulk pH is modest. Thus, the catalysis relies on the operation of two orthogonal interactions that bring the reaction partners together: hydrophobic guest binding in the cavity, which is lined with CH groups from the ligands, and ion pairing around the highly cationic cage surface. A consequence of this is that under some conditions the product of the cage catalyzed Kemp elimination (the 2-cyanophenolate anion) itself accumulates around the cage surface and deprotonates another benzisoxazole guest, perpetuating the reaction in an autocatalytic manner. Thus, different anions accumulating around the cage can act as partners for reaction with a cavity-bound guest, opening up the possibility that the M8L12 cage can act as a general catalyst for reactions of electrophilic guests with surface-bound anions.

The reductive metabolism of 1,2-benzisoxazole-3-methanesulfonamide (zonisamide) to 2-sulfamoylacetylphenol (SMAP) was observed in liver microsomes from female rats, as well as male rats, but the SMAP-producing activity in female rats was 4-fold lower than that found in male rats. In addition, the reductive metabolism of zonisamide in liver microsomes was induced by the treatment of male rats with phenobarbital. However, the SMAP-producing activity did not correlate positively with the amounts of P-450 2B1 and P-450 2C11 immunochemically determined. In contrast, the reductive metabolism of zonisamide was also found to be induced by the pretreatment of male rats with pregnenolone 16alpha-carbonitrile, triacetyloleandomycin, and dexamethasone. Furthermore, the SMAP-producing activity correlated highly with the amount of P-450 cross-reactive with antihuman P-450 3A4 antibody, suggesting that P-450 3A1/2 may function in the reductive metabolism of zonisamide. In addition, the P-450 PCNa (3A2) exhibited the SMAP-producing activity in a reconstituted system. The antihuman P-450 3A4 antibody inhibited markedly the formation of SMAP from zonisamide in male rat liver microsomes. These results indicate that cytochrome(s) P-450 belonging to P-450 3A subfamily may be predominantly responsible for the reductive metabolism of zonisamide in rat liver microsomes.

A selective and sensitive liquid chromatographic method was developed for the determination of zonisamide in small volumes of plasma. Zonisamide and the internal standard methyl 4-hydroxybenzoate were extracted from 0.2 mL. of plasma with solid-phase extraction columns and eluted with methanol. Analysis of the extracts was performed on a Symmetry C-18 column with ultra-violet spectrophotometric detection. The calibration curve was linear over the concentration range of 0.05-5 mug mL(-1) in plasma. Recoveries were reasonable for routine analyses; the limit of quantification was 0.05 mug mL(-1) with a signal-to-noise ratio of 5. This method could be useful for the pharmacokinetic study of zonisamide in a limited volume of human plasma and for therapeutic drug monitoring.
