A series of 1,2-benzisoxazole-3-carboxamides derived from tertiary cycloalkylamines was synthesized and evaluated for affinity for serotonergic (5-HT3 and 5-HT4) and dopaminergic (D-2) receptors using radioligand binding assays. The majority of compounds displayed a very weak affinity for the studied neurotransmitter receptors. Only amides containing a conformationally rigid system retained a relative 5-HT3 receptor affinity. The presence of a quinuclidine group affected receptor interaction more favorably than the tropane framework.

In order to understand better the relationship between auxin structure and activity on morphogenesis and cell elongation, six different auxins were tested on the regeneration of tomato (Lycopersicon esculentum Miller var. Alice) from cotyledons and on pea (Pisum sativum L. var. Alaska) stem elongation. The auxins were: indole-3-acetic acid (IAA), indole-3-butyric acid (IBA), 1, 2-benzisoxazole-3-acetic acid (BOA), 1,2-benzisothiazole-3-acetic acid (BIA), 1-naphthalenacetic acid (NAA), 2,4-dichlorophenoxyacetic acid (2,4-D). All these compounds obey the minimum requirement rules for auxin activity and all were effective on cell elongation. At the dose of 10-mu-M and in the absence of cytokinin, they all, except 2,4-D, induced roots, while in the presence of cytokinin they induced shoots, roots, hairy root-like filaments (HRLF) or callus depending on their concentration. The morphogenetic pattern did not change by varying cytokinin concentration. We conclude that auxin structure plays a minor role in morphogenesis or cell elongation, because it is only responsible for variations in the level of auxin activity.

Cyclic voltammetry and controlled-potential (bulk) electrolysis have been used to explore the electrochemical reduction of o-nitrobenzaldehyde (o-NBA) and 8 other aldehydes and ketones at glassy carbon cathodes in dimethylformamide containing various tetraalkylammonium tetrafluoroborate salts along with a proton donor (4-chlorophenol). Cyclic voltammograms for reduction of o-NBA exhibit three cathodic peaks attributable in succession to (a) one-electron generation of the nitro radical-anion, (b) three-electron formation of the hydroxylamine, and (c) two-electron production of benzisoxazole (anthranil). These findings have been employed to develop efficient controlled-potential (bulk) electrosyntheses of the following compounds: benzisoxazole, methylbenzo[c]isoxazole, [1,3]dioxolo[4 ‘,5 ‘,4,5]benzo[1,2-c]isoxazole, naphtho[2,3-c]isoxazole, 6-chlorobenzo[c]isoxazole, 6-methoxybenzo[c]isoxazole, 3-methyl-benzo[c]isoxazole, 3-isopropylbenzo[c]isoxazole, and 3-phenylbenzo[c]isoxazole. In addition, we have examined the use of a variety of proton donors to optimize the production of the desired product, and we have been able to recover the proton donor at the conclusion of the electrosynthesis. In each case, the synthesized product was separated by means of normal phase chromatography and identified with the aid of NMR spectros-copy, gas chromatography (GC), and gas chromatography-mass spectrometry (GC-MS). Isolated yields of the desired products range from 63 to 92 %. Moreover, our electrosyntheses are catalyst-free, environmentally green, and rapid (similar to 30 min).

Although the majority of people with epilepsy have a good prognosis and their seizures can be well controlled with pharmacotherapy, up to one-third of patients can develop drug-resistant epilepsy, especially those patients with partial seizures. This unmet need has driven considerable efforts over the last few decades aimed at developing and testing newer antiepileptic agents to improve seizure control. One of the most promising antiepileptic drugs of the new generation is zonisamide, a benzisoxazole derivative chemically unrelated to other anticonvulsant agents. In this article, the authors present the results of a systematic literature review summarizing the current evidence on the efficacy and tolerability of zonisamide for the treatment of partial seizures. Of particular interest within this updated review are the recent data on the use of zonisamide as monotherapy, as they might open new therapeutic avenues.

Objective: Delirium is a life-threatening neuropsychiatric syndrome characterised by disturbances in consciousness, attention, cognition and perception. Antipsychotics are considered the drugs of choice in managing the symptoms of delirium. Paliperidone is a benzisoxazole derivative and the principal active metabolite of risperidone. In this study, we aimed to evaluate the efficacy of paliperidone for the treatment of delirium. Methods: A prospective open-label study of paliperidone for delirium treatment was performed with 6-day follow-up. Fifteen patients who met Diagnostic and Statistical Manual of Mental disorders, Fourth Edition criteria for delirium and had a score of 13 on the Delirium Rating Scale were recruited. The starting dose was 3 mg once a day and the dose was adjusted depending on the status of delirium. Daily assessments of the severity of delirium were evaluated using Memorial Delirium Assessment Scale (MDAS). Results: The mean daily maintenance dose of paliperidone was 3.75 +/- 1.06. The MDAS scores before and after treatment (day 7) were 23.60 +/- 6.31 and 11.33 +/- 5.45 (t = 6.78, p < 0.001), respectively. The intensity of delirium showed a statistically significant reduction in MDAS scores from the first day of treatment. No serious adverse effects were observed, and none of the patients discontinued paliperidone because of adverse effects. Conclusions: This study shows that low-dose paliperidone is effective in reducing behavioural disturbances and symptoms in delirium and is well tolerated in delirious patients. This trial is an open-label study with a small sample size, and further controlled studies will be necessary. A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction.

Since it was first reported approximately 40 years ago that putative amino acid neurotransmitters, including GABA, would likely be inactivated by synaptic high-affinity transporters, there has been an exponential increase in interest in delineating the pharmacological characteristics of these transporters. During the 1980s and 1990s a large series of publications was devoted to a detailed characterization of neuronal and astroglial GABA transporters demonstrating important differences between these, a notion that turned out to be of relevance for the development of anticonvulsants targeting GABA transporters. The cloning era, leading to the identification of four proteins capable of transporting GABA across plasma membranes, has further boosted this research. Ultimately the clinically active antiepileptic drug, tiagabine, was developed and it was established that its mechanism of action involved inhibition of the GABA transporter-I (GATI). Current and future research is directed towards a better understanding of how extrasynaptic GABA receptors may be regulated via manipulation of extrasynaptic GABA levels, possibly involving extrasynaptic GABA transporters, most likely non-GATI transporters.

A series of novel 6-fluoro-3-(4-piperidinyl)-1,2-benzisoxazole derivatives 5(a-m) were synthesized with different substituted aromatic/heterocyclic acid chlorides (R-CO-Cl) and characterized by H-1 NMR, LC/MS, FTIR and elemental analyses. All the compounds synthesised were evaluated for their antiproliferative activity by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) assay. The antiproliferative effects of the synthesised compounds were tested against viable human skin fibroblast cells and carcinoma cells namely HeLa cells, HT-29 cells, MCF-7 cells, HepG-2 cells by adopting positive and negative control. The importance of the aromatic and heterocyclic moiety was confirmed. From the SAR studies, it reveals that, the substitution at N-terminal of 6-fluoro-3-(4-piperidinyl)-1,2-benzisoxazole by the heterocyclic ring plays a dominant role and was responsible for the antiproliferative activity. Among the synthesized compounds 5a, 5d and 5k have showed potent antiproliferative activity on all the carcinoma cells tested.
