New antiepileptic drugs: what’s in the future? Zonisamide

Zonisamide (1,2-benzisoxazole-3-methanesulphonamide) is structurally unrelated to other current or investigational antiepilepsy drugs (AEDs). It is marketed in Japan and South Korea and is undergoing clinical trials in the US and Europe. Substantial information has been collected about zonisamide from studies and from its widespread therapeutic use in Japan.

Absorption, distribution, metabolism and elimination of 14C-ETX0914, a novel inhibitor of bacterial type-II topoisomerases in rodents

1. ETX0914 is a novel bacterial topoisomerase inhibitor that has a novel mode-of-inhibition and is in clinical development for the treatment of infections caused by Neisseria gonorrhoeae. 2. The in vitro biotransformation studies of ETX0914 using mouse, rat, dog and human hepatocytes showed moderate intrinsic clearance in mouse and rat and low intrinsic clearance in dog and human. 3. Following intravenous administration of [C-14]-ETX0914 in rats, the mean recovery of administered dose in urine, bile and feces was approximately 15%, 55% and 24%, respectively. Unchanged ETX0914 recovered in urine and bile was less than 5% of the dose, indicating that ETX0914 underwent extensive metabolism in rats. Metabolites M1, M2, M4, M6 and M12 detected in both rat and mouse urine samples were not detected in mouse urine when predosed with 1-aminobenzotriazole, indicating that these metabolites were cytochrome P450 mediated products. The major fecal metabolites observed in rats were not formed when ETX0914 was incubated with fresh feces from germ free rats under sterile condition or in incubations with rat intestinal microsome and cytosol, suggesting that most likely ETX0914 was directly excreted into gut lumen where metabolites were formed as intestinal microflora-mediated products. The major sites of metabolism by CYP enzymes were in the morpholine and oxazolidinone rings while it was benzisoxazole reduction with the gut microflora.

Formation of 2-sulphamoylacetylphenol from zonisamide under aerobic conditions in rat liver microsomes

1. The antiepileptic agent zonisamide, 1,2-benzisoxazole-3-methanesulphonamide, was metabolized reductively to 2-sulphamoyl-acetylphenol (SMAP) not only under anaerobic conditions but also under aerobic conditions in liver microsomes of rat pretreated with phenobarbital or dexamethasone. 2. NADPH was required for the formation of SMAP from zonisamide under aerobic conditions. In addition, the reductive metabolism of zonisamide under these conditions was substantially inhibited by carbon monoxide, ketoconazole, and cimetidine, known inhibitors of cytochrome P450. 3. The formation of SMAP under aerobic conditions in liver microsomes was increased by pretreatment of rat with triacetyloleandomycin (TAO) and was increased by the treatment of the microsomes with ferricyanide. 4. These results imply that zonisamide is metabolized reductively to SMAP by a cytochrome P450 belonging to the 3A subfamily under aerobic conditions as well as anaerobic conditions.

Mechanism and Origins of Product Selectivity of Au-Catalyzed Coupling Benzisoxazoles with Ynamides: A Computational Study

Au(I)-catalyzed coupling of benzisoxazoles and ynamides was recently reported to synthesize challenging indoloquinoline core structures. In this report, we employed DFT methods to elucidate the mechanistic details of this reaction. The results reveal that the catalytic cycle involves initial coupling of ynamide with benzisoxazole, simultaneous ring opening of the isoxazole unit and attack of the dimethoxybenzene (DMOB) unit to gold carbenoid, proton transfer from the DMOB group to hydroxyl group, thioether migration, ring closure, and proton transfer. The experimentally observed ligand-controlled product selectivity is reproduced well by the calculations. The product selectivity-determining step is the ring opening of the isoxazole unit. The flexible P(t-Bu)(2)(o-biphenyl) ligand facilitates the approach of the DMOB group to gold carbenoid, which brings about significant C-H/pi interactions in the transition state for ring opening, and thus leads to the indoloquinoline product. The rigid 1,3-bis(diisopropylphenyl)imidazol-2-ylidene ligand prefers keeping the DMOB group away from the gold carbenoid, which can cause strong orbital interaction in the transition state for ring opening, and thus results in indole product.

Role of Water in the Multifaceted Catalytic Antibody 4B2 for Allylic Isomerization and Kemp Elimination Reactions

Specificity toward a single reaction is a well-known characteristic of catalytic antibodies. However, contrary to convention, catalytic antibody 4B2 possesses the ability to efficiently catalyze two unrelated reactions: a Kemp elimination and an allylic isomerization of a beta,gamma-unsaturated ketone. To elucidate how this multifaceted antibody operates, mixed quantum and molecular mechanics calculations coupled to Monte Carlo simulations were carried out. The antibody was determined to derive its adaptability for the mechanistically different reactions through the rearrangement of water molecules in the active site into advantageous geometric orientations for enhanced electrostatic stabilization. In the case of the Kemp elimination, a general base, Glu L34, carried out the proton abstraction from the isoxazole ring of 5-nitro-benzisoxazole while water molecules delivered specific stabilization at the transition state. The role of water was found to be more pronounced in the allylic isomerization because the solvent actively participated in the stepwise mechanism. A rate-limiting abstraction of the a-proton from the beta,gamma-unsaturated ketone via Glu L34 led to the formation of a neutral dienol intermediate, which was rapidly reprotonated at the gamma-position via a solvent hydronium ion. Preferential channeling of H3O+ in the active site ensured a stereoselective proton exchange from the alpha- to the gamma-position, in good agreement with deuterium exchange NMR and HPLC experiments. Ideas for improved water-mediated catalytic antibody designs are presented. In a technical advancement, improvements to a recent polynomial fitting and integration technique utilizing free energy perturbation theory delivered greater accuracy and speed gains.

Review of zonisamide development in Japan

Zonisamide is a benzisoxazole-based compound first synthesized in the early 1970s by the research laboratories of Dainippon Pharmaceutical Company in Osaka, Japan. Identified as an anticonvulsant during exploratory research, zonisamide has since been characterized as having broad-spectrum antiepitepsy and neuroprotective effects. Early clinical studies in Japan demonstrated that zonisamide has a long elimination half-life and is well tolerated; Phase II and III clinical trials established the drug’s efficacy and safety for the treatment of partial and generalized seizures. In 1989, zonisamide was approved and marketed in Japan under the trade name of Excegran(R). Data from postmarketing surveillance studies and clinical observations over 10 years of use have continued to support zonisamide’s efficacy and safety, identified its usefulness as monotherapy, and characterized its effectiveness for various seizure types and epilepsy syndromes.
