SYNTHESIS AND EVALUATION OF A SERIES OF 3,5-DISUBSTITUTED BENZISOXAZOLE-4,7-DIONES – POTENT RADIOSENSITIZERS INVITRO

A series of 3,5-disubstituted-2,1-benzisoxazole-4,7-diones was synthesized and evaluated as radiosensitizers both in vitro and in vivo. These compounds were designed as non-nitro electron-affinic agents in an effort to alleviate some of the toxicities seen with the 2-nitroimidazole radiosensitizers evaluated in the clinic. Several compounds in this series were potent radiosensitizers in vitro, with sensitizer enhancement ratios of 2.0-2.3 at concentrations < 0.5 mM. Compounds with potent in vitro activity were also evaluated in vivo. However, none of these compounds showed radiosensitizing activity in vivo. The reduction potentials of these compounds were determined by cyclic voltammetry and compared to other electron-affinic radiosensitizers. In general, the reduction potentials of this series of compounds was slightly more positive than the 2-nitroimidazoles, but they fell within the range postulated as acceptable to yield in vivo activity. The results suggest that factors other than reduction potential may be responsible for the lack of in vivo radiosensitizing activity observed for this class of radiosensitizers. We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, 627-03-2. The above is the message from the blog manager. Formula: C4H8O3.

Novel monoamine oxidase inhibitors, 3-(2-aminoethoxy)-1,2-benzisoxazole derivatives, and their differential reversibility

Although possible usefulness of non-selective monoamine oxidase (MAO) inhibitors for Parkinson’s disease therapy has been suggested in the literature, MAO inhibitors whose inhibition is reversible and have dual action to both MAO-A and -B subtypes is not available yet. Subtype selectivity and reversibility of a series of novel MAO inhibitors, 3-(2-aminoethoxy)-1,2-benzisoxazole derivatives, were studied. Several dual MAO inhibitors, which inhibit both MAO-A and -B, were obtained. When administered to mice, their effects were generally reversible. Among the derivatives, RS-1636 and RS-1653 had much longer duration of brain MAO-B inhibition than that of MAO-A. In vitro, the inhibited MAO-A activity by these compounds was partially recovered by buffer change at 4degreesC, while little MAO-B activity was recovered. Although it is not fully elucidated yet, the reversibility of these inhibitors is probably determined primarily by this dissociation profile. This unique differential reversibility indicates that optimization of the balance of actions can be achieved by differentiating reversibility to each target molecule.

Synthetic Route of 52356-01-1, Consequently, the presence of a catalyst will permit a system to reach equilibrium more quickly, but it has no effect on the position of the equilibrium as reflected in the value of its equilibrium constant.I hope my blog about 52356-01-1 is helpful to your research.

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.

HDAC and NF-kappa B mediated cytotoxicity induced by novel N-Chloro beta-lactams and benzisoxazole derivatives

Novel N-chloro a-Lactam and benzisoxazole derivatives were successfully synthesized with excellent yields (92-96%) under simple and mild reaction conditions. The beta-lactams as a class acquired importance since the discovery of penicillin which contains beta-lactam unit as an essential structural feature of its molecule, this interest continued unabated because of the therapeutic importance of beta-lactam antibiotics. In silico studies of the compounds with cancer drug target enzymes showed the inhibition of HDAC (Histone Deacetylase) and NF-kappa B (nuclear factor kappa-light-chain-enhancer of activated B cells) significantly. The compounds were then investigated for the inhibitory potential against the same enzymes in vitro. NF-kappa B inhibition was investigated by trans activation assay using HEK293/NF-kappa B-luc cells. Overall, the synthesized compounds induce the cancer cell toxicity by restraining the NF-kappa B transcription factor mediated by HDAC inhibition and thus the compounds act as dual inhibitors.

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.

Optimization and in vitro toxicity evaluation of G4 PAMAM dendrimer-risperidone complexes

Risperidone is an approved antipsychotic drug belonging to the chemical class of benzisoxazole. This drug has low solubility in aqueous medium and poor bioavailability due to extensive first-pass metabolism and high protein binding (>90%). As new strategies to improve treatments efficiency are needed, we have studied cationic G4 PAMAM dendrimers’ performance to act as efficient nanocarriers for this therapeutic drug. In this respect, we explored dendrimer risperidone complexation dependence on solvent, temperature, pH and salt concentration, as well as in vitro cytotoxicity measured on L929 cell line and human red blood cells. The best dendrimer risperidone incorporation was achieved when a mixture of 70:30 and 90:10 v/v chloroform:methanol was used, obtaining 17 and 32 risperidone molecules per dendrimer, respectively. No cytotoxicity on L929 cells was found when dendrimer concentration was below 3 x 10(-2) mu M and risperidone concentration below 5.1 mu M. Also, no significant hemolysis or morphological changes were observed on human red blood cells. Finally, attempting to obtain an efficient drug delivery system for risperidone, incorporation in G4 PAMAM dendrimers was optimized, improving drug solubility with low cytotoxicity.

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.
