1,2-Benzisoxazole compounds: a patent review (2009-2014)

Introduction: Benzisoxazoles represent a class of heterocyclic compounds of great importance for the preparation of biologically active compounds. Benzisoxazoles are an important structure and some benzisoxazole-based medicines have been approved for human clinical use, including atypical antipsychotics (risperidone, paliperidone and iloperidone) and an anticonvulsant (zonisamide). Areas covered: This review puts emphasis on the recent progress in therapeutically attractive benzisoxazole derivatives especially 1,2-benzisoxazoles, which were published in the patent literature between 2009 and 2014. As for the class of medicines, the main focus is on atypical antipsychotics and potential therapeutic treatments for other CNS disorders. This review also covers the examples of benzisoxazole-based kinase inhibitors. Moreover, novel benzisoxazoles with significant therapeutic interest are also mentioned. Expert opinion: More recent examples of structural modification of existing drugs led to the discovery of some promising benzisoxazoles for antipsychotic use. The design of multi-target ligands is important for the manipulation of pharmacological properties and safety profiles for the use of antipsychotics. Benzisoxazoles have been widely used as pharmacophores in the search for novel drug candidates in a variety of therapeutic area. It is fair to assume that the wide and frequent use of benzisoxazoles in drug discovery and development will continue into the future.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 4246-51-9, in my other articles.

A STAGE-SPECIFIC BLOCK IS PRODUCED IN CARROT SOMATIC EMBRYOS BY 1,2-BENZISOXAZOLE-3-ACETIC ACID

1,2-Benz-isoxazol-3-acetic acid is slightly toxic to unorganized growing carrot cells and completely prevents somatic embryogenesis beyond the globular stage. Its action is time dependent: if added early, it affects the determination of the early stages; if added later, after determination has occurred, it has practically no effect. The blocked forms can evolve, in the presence of the compound, creating secondary embryos that, in turn, are arrested at the globular stage. Since the secondary embryos adhere to the primary ones, irregular polyembryonic masses of typical appearance are created. The internal structures of the blocked globular embryos were examined and were shown to be enlarged, vacuolized and detached from the central cells. The protoderm also displayed an altered appearance. These data, when considered together with the effects of the compound on rooting and callus formation, suggest that benz-isoxazol acetic acid acts as a weak auxin.

A synthetic route to novel 3-substituted-2,1-benzisoxazoles from 5-(2-nitrobenzylidene)(thio)barbiturates

2,1-Benzisoxazoles, also called anthranils, are one of the two types of aromatic bicyclic heterocycles having a benzene ring fused with an isoxazole, which are particularly recognized as valuable intermediates in organic synthesis. Nevertheless several methods can be found in the literature to prepare 2,1-benzisoxazoles, we herein report a new, efficient, simple, mild, and alternative procedure to prepare 3-substituted-2,1-benzisoxazoles from 5-(2-nitrobenzylidene)barbiturates in moderate to good yields (51-82%). All the novel benzisoxazoles showed spectral data fully consistent with the assigned structures, which were unequivocally confirmed by single crystal X-ray analysis. A possible mechanism of the reaction is proposed. In addition, a screening of the bioactivity of these benzisoxazoles as xanthine oxidase inhibitors, antioxidants, and cytotoxic compounds was performed. The benzisoxazole formed from barbituric acid revealed moderate xanthine oxidase inhibitory effects (IC50 = 22.10 mu M). (C) 2017 Academie des sciences. Published by Elsevier Masson SAS.

Bacterial Degradation of Risperidone and Paliperidone in Decomposing Blood

The stability of two benzisoxazole antipsychotics was determined in vitro in decomposing porcine blood inoculated with bacteria, utilizing a high-performance liquid chromatography with ultraviolet and fluorescence detection method for drug quantitation. Stability experiments for risperidone and paliperidone were conducted at 7, 20 and 37 degrees C for 4 days using sterile and bacterially inoculated porcine blood. The drugs were stable in sterile blood at each temperature and in inoculated blood at 7 degrees C, but degraded significantly in inoculated blood at 20 and 37 degrees C. Complete loss occurred within 2 days when incubated at 37 degrees C. The benzisoxazole-cleaved degradation products for both drugs were identified as 2-hydroxybenzoyl-risperidone and 2-hydroxybenzoyl-paliperidone utilizing liquid chromatography quadrupole-time-of-flight mass spectrometry and accurate mass measurements. The degradation products have been found in postmortem case studies, including one case where risperidone and paliperidone were not detected, indicating complete conversion can occur in situ.

Cocrystals of zonisamide: physicochemical characterization and sustained release solid forms

We report four cocrystals of the antiepileptic drug, zonisamide (ZNS), which encounters half-life fluctuation when administered adjunctly with other antiepileptic drugs. Single crystals for two of the novel cocrystals of ZNS were successfully prepared from solvent evaporation experiments and their crystal structures were determined. Pharmaceutically acceptable cocrystals were analyzed for their dissolution rate, solubility and stability to draw conclusions on the impact of cocrystallization on the physicochemical properties of ZNS. It was found that the cocrystals showed lower solubility and dissolution rates and offer potential benefits in the development of sustained release formulations of ZNS which could address issues regarding its half-life fluctuation. Recent attempts to explore newer therapeutic applications have suggested ZNS as a potential drug for weight loss management. In this regard, the cocrystal of ZNS with caffeine, which has also been used in weight loss management, promises potential applications in the development of a novel fixed-dose combination drug which could offer synergistic therapeutic benefits in the treatment of obesity.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 135236-72-5 is helpful to your research. Formula: C10H18CaO6.

Evaluation of zonisamide for the treatment of focal epilepsy: a review of pharmacokinetics, clinical efficacy and adverse effects

Introduction: Zonisamide is a benzisoxazole with 3-methanesulfonamide side chain, chemically unrelated with other anticonvulsants, and approved as mono-therapy of newly diagnosed focal epilepsy with or without secondary generalization in adults or adjunctive therapy in the treatment of partial seizures, with or without secondary generalization, in adults, adolescents, and children aged 6 years and above. Areas covered: Pharmacokinetics, clinical efficacy, and the adverse effects of zonisamide are discussed in the article. The discussion is based on data from published preclinical studies, clinical trials, observational studies, systematic reviews, and approved summary of product characteristics. Expert opinion: Zonisamide is an anticonvulsant with multiple mechanisms of action on neuronal tissue, which achieves seizure freedom in more than 80% of patients with newly-onset focal epilepsy and in 6.2 to 18.1% of patients with focal onset seizures inadequately controlled by first-line anticonvulsants. Within the recommended dose range, it follows linear kinetic of elimination; it is metabolized in the liver by two cytochrome isoforms, so pharmacokinetic interactions are rare and with little clinical significance. Up to 10% of patients taking zonisamide will have problems with weight loss and more than 10% with irritability, confusion or depression, and long-lasting therapy may cause renal calculi in 1.2% of patients.

Synthesis and evaluation of amide, sulfonamide and urea – benzisoxazole derivatives as potential atypical antipsychotics

In this paper, we report the optimization of a series of novel, potential antipsychotic derivatives combining potent dopamine D-2, D-3 and serotonin 5-HT1A, 5-HT2A receptor affinities. The pharmacological features of compound 27 are a high affinity for dopamine D-2, D-3 and serotonin 5-HT1A, 5-HT2A receptors. Moreover it possesses low affinity for 5-HT2C and H-1 receptors (to reduce the risk of obesity associated with chronic treatment) and hERG channels (to reduce the incidence of torsade des pointes). Furthermore, compound 27 inhibited apomorphine-induced climbing, MK-801-induced hyperactivity and DOI-induced head twitch without observable catalepsy at the highest dose tested in mice. Taken together, among the amide derivatives, we identified compound 27 as a potential antipsychotic lead candidate.

A PHARMACOLOGICAL, PHARMACOKINETIC AND CLINICAL OVERVIEW OF RISPERIDONE, A NEW ANTIPSYCHOTIC THAT BLOCKS SEROTONIN 5-HT2 AND DOPAMINE D-2 RECEPTORS

Risperidone is a benzisoxazole derivative with antipsychotic activity that is chemically unrelated to other currently available antipsychotic agents, Its neuropharmacological properties, characterized by potent central antagonism of both serotonin 5-HT2 and dopamine D-2 receptors, also differ from those of most other antipsychotic drugs, The pharmacokinetics of risperidone are well understood, having been studied in healthy subjects as well as in psychotic patients. The absolute oral bioavailability of risperidone is nearly 70%, and after oral administration, it is rapidly absorbed with the plasma level reaching a peak at about 1 h. 9-Hydroxyrisperidone, one of the metabolites of risperidone, is equally active with the parent compound and so the clinical activity of a dose of risperidone is due to the combined actions of both moieties, The plasma concentrations of risperidone and its active metabolite remain dose proportional even at doses exceeding the therapeutic range. In clinical trials with chronic schizophrenia patients, risperidone has an overall therapeutic activity comparable with that of haloperidol, but at doses that produce similar improvements in the positive symptoms of schizophrenia, risperidone has a greater effect on the negative symptoms and produces less extrapyramidal side effects than does haloperidol, However, additional controlled clinical studies are needed before the claims that risperidone is therapeutically superior to haloperidol cah be considered to be established firmly, Although risperidone is effective in acute schizophrenia and in non-treatment-resistant schizophrenics, studies adequately comparing risperidone with clozapine in treatment-resistant schizophrenic patients remain to be published. In addition, risperidone has been reported to be of value in patients with schizodepressive disorders, The clinical success of risperidone suggests that the development of compounds with selective affinity for 5-HT2 or other serotonin receptors may result in even further improvements in the pharmacotherapy of psychiatric disorders.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 427-49-6. Safety of alpha-Cyclopentylmandelic Acid.
