Research and development of zonisamide, a new type of antiepileptic drug

Zonisamide (1,2-benzisoxazole-3-methanesulfonamide, AD-810) is a broad spectrum antiepileptic drug which has been launched in Japan and South Korea. It lacks the ureide structure included in most of the existing antiepileptic drugs. Zonisamide was synthesized by the sulfonation and the successive amination of 1,2-benzisoxazole-3-acetic acid in a very poor yield. After several efforts to optimaize the compound, zonisamide was selected based on the balance of the efficacy and safety. The yield was greatly improved by the development of new synthetic routes. Zonisamide suppressed maximal electroshock seizures in mice, rats, rabbits and dogs. Its therapeutic plasma concentration range between anticonvulsant and neurotoxic effects was much wider than that of the existing antiepileptic drugs. In electroencephalographic studies on animal models of epilepsy, zonisamide, like phenytoin and carbamazepine, restricted the spread or propagation of seizures and, like sodium valproate, it suppressed the epileptogenic focus activity. Zonisamide was effective in several kindling models. In clinical studies, zonisamide exerted the efficacy against partial seizures (simple, complex, secondarily generalized seizures and some generalized seizures (tonic-clonic, tonic, atypical absence seizures) that were comparable to that of carbamazepine and sodium valproate, respectively. Zonisamide was also effective in monotherapy. The adverse effects related with zonisamide were mainly drowsiness, ataxia, loss of appetite and gastrointestinal symptoms. Serious adverse effects which may be life-threatening have not been reported.

A convenient method for the preparation of 2-aminobenzophenone derivatives under ultrasonic irradiation

A quick and convenient method for the preparation of 2-aminobenzophenone derivatives is described. This approach consists of the nucleophilic substitution reaction of nitrobenzenes by phenylacetonitrile under conventional and ultrasonic conditions followed by reduction of the produced 2,1-benzisoxazole to 2-aminobenzophenone. This 2-step reaction was studied by changing the reaction parameters (reaction temperature, ultrasound power, and reaction time). The results clearly demonstrated that using ultrasound irradiation results in a high yield within a short reaction time.

Development of OPLS-AA Force Field Parameters for 68 Unique Ionic Liquids

OPLS-AA force field parameters have been developed and validated for use in the simulation of 68 unique combinations of room temperature ionic liquids featuring 1-alkyl-3-methylimidazolium [RMIM] (R = Me, Et, Bu, Hex, Oct), N-alkylpyridinium [RPyr], and choline cations, along with Cl-, PF6-, BF4-, NO3-, AlCl4-, Al2Cl7-, TfO-, saccharinate, and acesulfamate anions. The new parameters were fit to conformational profiles from gas-phase ab initio calculations at the LMP2/cc-pVTZ(-f)//HF/6-31 G(d) theory level and compared to experimental condensed-phase structural and thermodynamic data. Monte Carlo simulations of the ionic liquids, gave relative deviations from experimental densities of ca. 1-3% at 25 degrees C for most combinations and also yielded close agreement over a temperature range of 5 to 90 degrees C. Predicted heats of vaporization compared well with available experimental data and estimates. Transferability of the new parameters to multiple alkyl side-chain lengths for [RMIM] and [RPyr] was determined to give excellent agreement with charges and torsion potentials developed specific to desired alkyl lengths in 35 separate ionic liquid simulations. As further validation of the newly developed parameters, the Kemp elimination reaction of benzisoxazole via piperidine was computed in 1-butyl-3-methylimidazolium hexafluorophosphate [BMIM][PF6] using mixed quantum and molecular mechanics (QM/MM) simulations and was found to give close agreement with the experimental free energy of activation.

Molecular docking and simulation studies of 3-(1-chloropiperidin-4-yl)-6-fluoro benzisoxazole 2 against VP26 and VP28 proteins of white spot syndrome virus

White spot syndrome virus (WSSV), an aquatic virus infecting shrimps and other crustaceans, is widely distributed in Asian subcontinents including India. The infection has led to a serious economic loss in shrimp farming. The WSSV genome is approximately 300 kb and codes for several proteins mediating the infection. The envelope proteins VP26 and VP28 play a major role in infection process and also in the interaction with the host cells. A comprehensive study on the viral proteins leading to the development of safe and potent antiviral therapeutic is of adverse need. The novel synthesized compound 3-(1-chloropiperidin-4-yl)-6-fluoro benzisoxazole 2 is proved to have potent antiviral activity against WSSV. The compound antiviral activity is validated in freshwater crabs (Paratelphusa hydrodomous). An in silico molecular docking and simulation analysis of the envelope proteins VP26 and VP28 with the ligand 3-(1-chloropiperidin-4-yl)-6-fluoro benzisoxazole 2 are carried out. The docking analysis reveals that the polar amino acids in the pore region of the envelope proteins were involved in the ligand binding. The influence of the ligand binding on the proteins is validated by the molecular dynamics and simulation study. These in silico approaches together demonstrate the ligand’s efficiency in preventing the trimers from exhibiting their physiological function.

Overview of Japanese experience-controlled and uncontrolled trials

Zonisamide is a new type of benzisoxazole derivative, first marketed in Japan in 1989. This study analyzed: (1) the drug’s efficacy by seizure and epilepsy type in a total of 1008 patients treated during the development of zonisamide in Japan; (2) the effectiveness of zonisamide for 726 newly-diagnosed patients treated with zonisamide postmarketing; and (3) 50 patients with generalized epilepsies and epileptic syndromes (idiopathic generalized epilepsies, symptomatic generalized epilepsies, Lennox-Gastaut syndrome, Doose syndrome, and West syndrome), and 19 patients with undetermined epilepsies and specific syndromes (refractory grand mat in childhood, severe myoclonic epilepsy in infancy, other undetermined epilepsy, familial. essential myoclonic epilepsy, and mitochondrial encephalomyopathy with ragged-red fibers). Analysis of study results showed that among all patients treated, zonisamide was highly effective for the treatment of idiopathic generalized epilepsy, temporal lobe epilepsy, and other partial epilepsies. The compound was also effective for other symptomatic generalized epilepsies. In 50 patients with generalized epilepsies, and 19 with undetermined epilepsies and specific syndromes, seizure frequency was reduced by >50% with monotherapy or two-drug therapy with zonisamide. Zonisamide was effective not only for partial epilepsies and generalized epilepsies but also for undetermined epilepsies and specific syndromes such as myoclonus epilepsy. (C) 2004 BEA Trading Ltd.

Aromaticity of anthranil and its isomers, 1,2-benzisoxazole and benzoxazole

Direct computation of the pi-current density, that is, the ‘ring current’, of anthranil (1) and its isomers 1,2-benzisoxazole (2) and benzoxazole (3) reveals different patterns of current flow: isomers 2 and 3 sustain strong benzene-like currents in the six-membered and bifurcated flow in the five-membered ring, whereas, in keeping with its lower thermodynamic stability, 1 has only a perimeter circulation without separate monocycle currents. Although the ring current criterion does not offer a sharp distinction between 2 and 3, their difference in thermodynamic stability is identical to that between isoxazole (4) and oxazole (5) suggesting an aromaticity order 1 < 2 approximate to 3.

Biotransformation of post-clozapine antipsychotics – Pharmacological implications

The need to develop new antipsychotics that have fewer motor adverse effects and offer better treatment of negative symptoms has led to a new generation of drugs. Most of these drugs undergo extensive first-pass metabolism and are cleared almost exclusively by metabolism, except for amisulpride whose clearance is largely due to urinary excretion. Risperidone has metabolic routes in common with ziprasidone but shows differences in regard to other main pathways: the benzisoxazole moiety of risperidone is oxidised by cytochrome P450 (CYP) 2D6 to the active 9-hydroxyrisperidone, whereas the benzisothiazole of ziprasidone is primarily oxidised by CYP3A4, yielding sulfoxide and sulfone derivatives with low affinity for target receptors in vitro. Olanzapine, quetiapine and zotepine also have some common metabolic features. However, for the thienobenzodiazepine olanzapine a main metabolic route is direct conjugation at the benzodiazepine nucleus, whereas for the dibenzothiazepine quetiapine and the dibenzothiepine zotepine iris CYP3A4-mediated oxidation, leading to sulfoxidation, hydroxylation and dealkylation for quetiapine, but N-demethylation to the active nor-derivative for zotepine. Although the promising benzisoxazole (iloperidone) and benzisothiazole (perospirone) antipsychotics share some metabolic routes with the structurally related available drugs, they too have pharmacologically relevant compound-specific pathways. For some of the new antipsychotics we know the isoenzymes involved in their main metabolic pathways and the endogenous and exogenous factors that, by affecting enzyme activity, can potentially modify steady-state concentrations of the parent drug or its metabolite(s), but we know very little about others (e.g. amisulpride isomers, nemonapride). For yet others, information is scarce about the activity of the main metabolites and whether and how these contribute to the effect of the parent drug. Aging reduces the clearance of most antipsychotics, except amisulpride (which requires further evaluation) and ziprasidone. Liver impairment has little or no effect on the pharmacokinetics of olanzapine, quetiapine, risperidone (and 9-hydroxy-risperidone) and ziprasidone, but information is lacking for amisulpride. Renal impairment significantly reduces the clearance and prolongs the elimination half-life of amisulpride and risperidone. Again, studies are still not available for some drugs (zotepine) and have focused on the parent drug for others (olanzapine, quetiapine, ziprasidone) despite the fact that renal impairment would be expected to lower the clearance of more polar metabolites. Addressing these issues may assist clinicians in the design of safe and effective regimens for this group of drugs, and in selecting the best agent for each specific population.
