Background: Triple Negative Breast Cancer (TNBC) tends to be more aggressive than other types of breast cancer. Resistance to chemotherapy is a major obstacle hence there is a significant need for new antineoplastic drugs with multi-target potency. Numerous Benzoisoxazole moieties have been found to possess a broad spectrum of pharmacological activities. In the present study, we have synthesized 9 novel derivatives of Benzisoxazole 7(a-i) and screened them for their biological potential. Methods: Chemical synthesis, Mass spectrometry (HRMS), cell proliferation and cytotoxicity assay, wound healing assay, flow cytometry and nuclear staining. Angio-inhibitory activity assessed by corneal micropocket assay and in vivo peritoneal angiogenesis assay. Results: The Benzisoxazole derivatives 7(a-i) were synthesized and screened for their biological potency by both in vitro and in vivo experimental models. Among the series, compound 3-(1-((3-(3(Benzyloxy)-4-methoxyphenyl)4,5-dihydroisoxazole-5-yl) methyl)piperidine-4-yl)6-fluorobenzo[d] isoxazole (7e) was found to be most promising, with an average IC50 value of 50.36 +/- 1.7 mu M in MTT assay and showed 81.3% cell death. The compound 7e also showed 60-70% inhibition on a recombinant Metastasis-Associated protein (MTA1) induced proliferation and cell migration in MDAMB-231 cells, which is known to play a major role in angiogenesis. The anti-tumour studies inferred the regression of tumour activity. This was due to inhibition of neovascularization and evoking apoptosis process as assessed by corneal vascularization, peritoneal angiogenesis and apoptotic hallmarks in 7e treated cells. Conclusion: These findings not only show the biological efficacy of compound 7e but it is also an effective beginning to explore the mechanism of metastasis and cancer therapy strategy targeting MTA1. The observed biological activity makes compound 7e an attractive drug candidate.

Photochemistry of 3-chloro-1,2-benzisoxazole 1 in N-2 and Ar matrices at 10 K leads to N-chloro-ketenimine 3 and 2-cyanophenyl-hypochlorite 4. The reaction kinetics and the observed photoisomerization of 3 to 4 indicate that ketenimine 3, possibly formed via an elusive vinylnitrene VN, is an intermediate in the formation of hypochlorite 4. A new pathway involving the formation of 2-cyanophenoxyl radical 5, which was captured only in Ar matrix, was also observed. Radical 5 is possibly formed via photo detachment of CI atom from I (or VN) and might explain the formation of 3-chloro-6-oxocyclohexa-1,4-dienecarbonitrile 2 in N2 and Ar matrices. All the species were characterized by IR spectroscopy and theoretical calculations. The computed geometric and electronic structure of radical 5 is discussed. Overall, the results provided further insight into the mechanism of the photochemistry of 1,2-benzisoxazoles and allowed characterization of new interesting reactive intermediates.

The influence of solvent donor-acceptor properties and polarity on the rates of decarboxylation of benzisoxazole-3-carboxylate ions is analyzed with the unified solvation model. When the dissolved species is a separated ion pair, solvent polarity decreases the rate. When an equilibrium exists between an ion pair and the dissociated ion pair, solvent polarity and donor strength increase the rate by increasing the extent of dissociation. Hydrogen bonding to the carboxylate functionality causes a significant decrease in rate. When using this probe to measure the solvation properties of solvents, micelles, polymers, or biological assemblies, these different effects must be sorted out to interpret the influence of the medium on the observed rate. The unified solvation model provides a means of sorting out these various contributions.

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 6009-70-7, in my other articles.

In recent year syria rejuvenate interest in chemical warfare agents (CWAs) for terrorist attacks. Nerve agents are the most scandalous chemicals and can cause death of a person owing to the inhibition of acetyl cholinesterase activity. In this article, we report a colorometric and ratiometric fluorescent probe 4-diphenylamino-2-hydroxy benzaldehyde oxime (TPOD) that could be efficient of instant and real-time recording of DCP vapour. Upon reaction with DCP, bathochromic shift from similar to 463 to similar to 532 nm was observed due to the inhibition of PET from oxime-hydroxyl to the triphenyl amine moiety and cyclization to the benzisoxazole. The transformation from oxime to benzisoxazole was confirmed by NMR and HRMS data. The probe TPOD can be applied on a portable and cost effective test kits where in presence of DCP vapour dramatic color and fluorescence change were observed within 30 s. Furthermore, the probe can efficiently detect DCP in presence of other nerve agents and electrophile and the detection limit is 0.14 mu M. Moreover to evaluate the sensing mechanism we have prepared a control compound TPD whose crystal structure and non covalent interactions have been incorporated. To achieve the on-site application of TPOD we have performed an experiment in soil sample to detect trace amount of DCP. Moreover the probe can be useful in cellular imaging of DCP containing bio-samples. Thus the probe TPOD is an auspicious, instant and on site monitoring ratiometric fluorescent probe for selective DCP detection in presence of other interfering nerve agents.

Zonisamide is increasingly used in pediatric neurology but there are no experimental data for immature animals. Zonisamide (12.5-100 mg/kg i.p.) was tested against pentetrazol-induced seizures in 7-, 12-, 18-, 25- and 90-day-old rats. Minimal clonic seizures were not suppressed by zonisamide. Selective suppression of tonic phase of generalized tonic-clonic seizures was demonstrated in all age groups. This effect indicates possible action of zonisamide against generalized tonic-clonic seizures during brain maturation. (C) 2010 Published by Elsevier B.V.

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. A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction.
