Effect of vesicles of dimethyldioctadecylammonium chloride and phospholipids on the rate of decarboxylation of 6-nitrobenzisoxazole-3-carboxylate

Sonicated mixtures of dimethyldioctadecylammonium chloride (DODAC), egg phosphatidylcholine (PC), dimyristoyl phosphatidylcholine (DMPC), and dipalmitoyl phosphatidylcholine (DPPC) were used to analyze vesicle effects on the rate of decarboxylation of 6-nitrobenzisoxazol-3-carboxylic acid (Nboc). Electron microscopic images of the vesicles were obtained with trehalose, a know cryoprotector. Phase diagrams and phase transitions temperatures of the vesicle bilayers were determined. Nboc decarboxylation rates increased in the presence of vesicles prepared with both phospholipids and DODAC/phospholipid mixtures. Quantitative analysis of vesicular effects was done using pseudophase models. Phospholipids catalyzed up to 140-fold while the maximum catalysis by DODAC/lipid vesicles reached 800-fold. Acceleration depends on alkyl chain length, fatty acid insaturation of the lipids, and the DODAC/phospholipid molar ratio. Catalysis is not related to the liquid crystalline-gel state of the bilayer and may be related to the relative position of Nboc with respect to the interface.

ZONISAMIDE: A NEW DRUG FOR PARKINSON’S DISEASE

Zonisamide, a benzisoxazole derivative, is an antiepileptic drug with a long half-life. Three nationwide, double-blind, placebo-controlled studies carried out in Japan prompted the approval of zonisamide as an antiparkinsonian agent in early 2009. The addition of zonisamide at 25-50 mg/day to currently used antiparkinsonian drugs significantly improved cardinal symptoms in patients with advanced Parkinson’s disease. The effects were maintained over more than 1 year even in patients with advanced disease. Zonisamide has multiple modes of action, and its effects on Parkinson’s disease include activation of dopamine synthesis, inhibition of monoamine oxidase, inhibition of T-type calcium channels and inhibition of an indirect pathway in the basal ganglia through the delta opioid receptor Furthermore, zonisamide exhibits neuroprotective effects in animal models of Parkinson’s disease. It strongly inhibits quinoprotein formation and markedly increases glutathione S-transferase levels in the striatum by enhancing the astroglial cysteine transport system and/or astroglial proliferation via S100 beta production and secretion.

Synthesis of elastin based peptides conjugated to benzisoxazole as a new class of potent antimicrobials – A novel approach to enhance biocompatibility

The peptides of elastin sequences chosen for the present study included tetrapeptides, pentapeptides and tricosapeptides (30 amino acids), synthesized by classical solution phase method and conjugated to [3-(4-piperidyl)-6-fluoro-1,2-benzisoxazole]. The structures of the compounds were confirmed by physical and spectroscopic techniques followed by the antimicrobial evaluation by both agar well diffusion and microdilution methods. Here we wish to report the effect of conjugation of these moieties which enabled us to identify a novel set of peptides conjugated to heterocycle which have exhibited more potent antimicrobial activity than the conventional drugs used. Further, conjugates of tricosamers 34 and 35 were able to inhibit the growth of fungal species at 3-5 mu g/mL which is nearly 5 fold more potent than the reference drug. (C) 2010 Elsevier Masson SAS.

Benzisoxazole: a privileged scaffold for medicinal chemistry

The benzisoxazole analogs represent one of the privileged structures in medicinal chemistry and there has been an increasing number of studies on benzisoxazole-containing compounds. The unique benzisoxazole scaffold also exhibits an impressive potential as antimicrobial, anticancer, anti-inflammatory, anti-glycation agents and so on. This review examines the state of the art in medicinal chemistry as it relates to the comprehensive and general summary of the different benzisoxazole analogs, their use as starting building blocks of multifarious architectures on scales sufficient to drive human drug trials. The number of reports describing benzisoxazole-containing highly active compounds leads to the expectation that this scaffold will further emerge as a potential candidate in the field of drug discovery.

SYNTHESIS AND ANTIMICROBIAL ACTIVITY OF NOVEL SULFIDES AND SULFONES OF METHYLENE-BRIDGED BENZISOXAZOLYLIMIDAZO[2,1-b][1,3,4]THIADIAZOLES

Novel classes of 3-(6-Aryl-5-phenylsulfanylimidazo[2,1-b][1,3,4]thiadiazol-2-yl-methyl)-benzo[d]isoxazoles (2a-f) and 3-(5-Benzenesulfonyl-6-arylimidazo[2,1-b][1,3,4] thiadiazol-2-yl-methyl)-benzo[d]isoxazoles (3a-f) have been synthesized. The sulfide derivatives (2a-f) were obtained by the nucleophilic substitution of bromo derivatives (1a-f) with thiophenols, and sulfone derivatives (3a-f) were obtained by the oxidation of 2a-f. All the newly synthesized compounds were characterized by elemental analysis, infrared, nuclear magnetic resonance, and mass spectroscopic data. Furthermore, these novel sulfide and sulfone derivatives were screened for their antibacterial and antifungal activities against various microorganisms.

Synthesis and evaluation of radioiodine-labelled CP-118,954 for the in-vivo imaging of acetylcholinesterase

Objectives Alzheimer’s disease (AD) is characterized by reduced acetylcholinesterase (AChE) activity in the postmortem tissues of AD patients. Therefore, AChE has been an attractive target for the diagnosis of AD. In the present study, 5,7-dihydro-3-[2-(1-(phenyimethyl)-4piperidinyl)ethyl]-6H-pyrrolo[3,2-f]-1,2-benzisoxazol-6-one (CP-118,954), a potent AChE inhibitor, was labelled with radiolodine and evaluated as an AChE imaging agent for SPECT. Methods Radioiodine-labelled CP-118,954 was prepared from CP-144,885 and [I-125]iodobenzyl bromide, and anti-AChE activities of iodine-substituted CP-118,954 were measured. Metabolism studies were carried out in samples of blood and whole brain of mice injected with 2[I-123]iodo-CP-118,954 (I-123-1). Tissue distribution studies were also performed in mice injected with I-125-1, and samples of blood, thyroid, stomach, and brain tissue (cerebellum, striatum and cortex) were removed, weighed and counted. Results Of the ligands, 2-iodo-CP-118,954 exhibited higher binding affinity for AChE (IC50 = 24 nM) than the other positional isomers. 2-[I-125]lodo-CP-118,954 was found to have a lipophilicity (log P=2.1) favouring brain permeability and metabolic stability in mouse brain, but a marginal target (striatum) to non-target (cerebellum) uptake ratio (1.1) in mouse brain. Conclusion This result demonstrates that 2-[I-125]iodo-CP-118,954 may be unsuitable for AChE imaging. These findings suggest that radioligands suitable for AChE imaging should have not only a specific structure but also a sub-nanomolar to low nanomolar IC50.

REDUCTIVE METABOLISM OF THE ANTICONVULSANT AGENT ZONISAMIDE, A 1,2-BENZISOXAZOLE DERIVATIVE

1. The metabolism of zonisamide in vitro was characterized through aerobic and anaerobic incubations with rat liver subcellular fractions and cultured gastrointestinal microflora. 2. Zonisamide reacted with rat hepatic microsomal cytochrome P-450 and exhibited a Type I binding spectrum. 3. Metabolism of zonisamide in vitro by hepatic subcellular fractions and cultured gastrointestinal flora produced a single metabolite, 2-(sulphamoylacetyl)-phenol (2-SMAP), by reductive cleavage of the 1,2-benzisoxazole ring. 4. The reductive metabolism of zonisamide was primarily mediated by microsomal cytochrome P-450. The soluble fraction enhanced reduction when combined with the microsomal fraction but itself possessed only weak reductive activity. 5. Reduction of zonisamide by the most enzymically active liver fractions required NADPH, was stimulated by FMN and SKF-525A, and was inhibited by CO or air, as well as by n-octylamine. 6. Unlike their involvement in the reduction of numerous nitro, azo, and N-oxide compounds, cultured aerobic and anaerobic intestinal flora were not principally involved in the reduction of zonisamide.

STUDIES ON URICOSURIC DIURETICS .5. CONVENIENT AND EFFICIENT SYNTHESIS OF 2,3-DIHYDROBENZOFURAN DERIVATIVES

A practical procedure for synthesis of a new uricosuric agent, 5-chloro-7,8-dihydro-3-phenylfuro[2,3-g]-1,2-benzisoxazole-7-carboxylic acid (1, AA-193) is described, which starts from 2,5-dichlorophenol (3b) and involves 5-chloro-6-hydroxy-3-phenyl-1,2-benzisoxazole (2) as the key intermediate. Successive treatment of 3b with benzoyl chloride-aluminum chloride (AlCl3) and hot ethanolic sodium hydroxide gives 4-benzoyl-2,5-dichlorophenol (8, 61%), which is oximated with hydroxylamine hydrochloride and then transformed into the benzisoxazole 2 (88%) with potassium hydroxide in N,N-dimethylformamide (DMF) (method C). The reaction of 2 with aqueous formaldehyde and dimethylamine affords the Mannich base Ila (97%), which is treated with a sulfonium ylide 12, 14 or 15 followed by heating with sodium hydroxide (NaOH) in ethanol (EtOH) to give 1 in high yield (method E).

ZONISAMIDE – A REVIEW OF ITS PHARMACODYNAMIC AND PHARMACOKINETIC PROPERTIES, AND THERAPEUTIC POTENTIAL IN EPILEPSY

Zonisamide is a 1.2 benzisoxazole derivative and the first agent of this chemical class to be developed as an antiepileptic dry. It has shown activity in various animal models of epilepsy, and although a detailed mode of action awaits clarification it appears to block the propagation/spread of seizure discharges and to suppress the epileptogenic focus. Clinical experience with zonisamide in Japan has documented its efficacy in the treatment of partial seizures (partial-onset generalised tonic-clonic, simple partial and/or complex partial seizures), and to a more variable extent, generalised tonic-clonic, generalised tonic (mainly seen in symptomatic generalised epilepsies including Lennox-Gastaut Syndrome) and compound/combination seizures (including those refractory to treatment with other antiepileptic drugs). Other generalised seizure types have also responded to therapy with zonisamide, although only small patient numbers were studied. Zonisamide has demonstrated efficacy equivalent to that of carbamazepine in patients with (mainly) partial seizures, and to that of valproic acid in a small study of children (n = 32) with generalised seizures. Animal studies suggest that zonisamide possesses a more favourable therapeutic index than most other antiepileptic drugs. However, clinical trials conducted to date, have not confirmed any overt tolerability advantage. Indeed, whereas the recommended therapeutic plasma zonisamide concentration is 20 mg/L, clinical investigations have associated adverse events with plasma zonisamide concentrations of >30 mg/L. suggesting the usefulness of therapeutic drug monitoring. Moreover, although plasma concentrations of zonisamide are empirically regarded to be proportional to therapeutic doses in patients in Japan, nonlinear pharmacokinetics have been reported for this drug in patients in the US and may further complicate its use in this patient population. Additional pharmacokinetic studies will help to establish the change in pharmacokinetic profile that occurs with dosage titration in patients outside Japan. Among 700 patients treated with zonisamide in Europe/US, a high incidence of renal calculi (1.9%) has been noted however, the causal relationship to zonisamide is disputed. Indeed, although urinary lithiasis has also been recorded for patients in Japan, the aetiology, incidence and spontaneous regression of this condition suggest that it is not a serious problem for this patient population. Until this difference is clarified, it is likely that zonisamide will find its greatest use in the treatment of patients in Japan. Like many other established antiepileptic drugs, available data suggest the propensity for zonisamide to alter the pharmacokinetic profile of other anticonvulsant agents, although severe interactions appear to be unlikely. The ultimate positioning of zonisamide in the therapy of epilepsy awaits clearer definition of its pharmacokinetic, efficacy (particularly in comparison with other antiepileptics) and tolerability profiles. At present therefore, available data do not support the use of this drug in individuals outside of Japan, except in formal clinical studies involving careful monitoring. However, for patients in Japan with epilepsies refractory to established therapy, zonisamide would appear a valid alternative, particularly in the treatment of partial seizures.
