Microwave-promoted synthesis of 3-amino-substituted 1,2-benzisoxazoles

Background: 1,2-benzisoxazole derivatives have been the focus of numerous studies, due to their biological and chemical interest. Results: We demonstrate an efficient synthesis of a series of 3-amino-substituted 1,2-benzisoxazoles from a 3-chloro-1,2-benzisoxazole by microwave-promoted nucleophilic aromatic substitution. The 3-amino-1,2-benzisoxazoles prepared were obtained in 1-6 h in good-to-high yields of 54-90%. The 3-chloro-1,2-benzisoxazoles were also prepared by heating with microwave irradiation in quantitative yields in 2 h, from the corresponding 3-hydroxy-1,2-benzisoxazoles. Conclusion: This efficient microwave-assisted pathway could be applied to a variety of substrates in the further development of substituted 1,2-benzisoxazoles.

Synthesis of 1,2-benzisoxazole tethered 1,2,3-triazoles that exhibit anticancer activity in acute myeloid leukemia cell lines by inhibiting histone deacetylases, and inducing p21 and tubulin acetylation

1,2,3-Triazole-based heterocycles have previously been shown to possess significant anticancer activity in various tumor models. In the present study, we attached a 1,2,3-triazole moiety to the third position of a 1,2-benzisoxazole heterocycle via copper(I)-catalyzed azide-alkyne cycloaddition (CuAAC) with various alkynes and established for the title compounds significant antiproliferative effect against human acute myeloid leukemia (AML) cells. Among the tested compounds, 3-(4-(4-phenoxyphenyl)-1H-1,2, 3-triazol-1-yl) benzo[d] isoxazole (PTB) was found to be the most potent antiproliferative agent with an IC50 of 2 mu M against MV4-11 cells using MTT assay. Notably, PTB induced cytotoxicity in MOLM13, MOLM14 and MV4-11 cells with selectivity over normal bone marrow cells (C57BL/6). Furthermore, PTB was found to induce cytotoxicity by increasing apoptosis of AML cells (MOLM13, MOLM14 and MV4-11) as well as sub-G1 cell population and apoptotic cells at submicromolar concentrations, as shown by flow cytometry and Annexin-V staining, respectively. On the protein level we suggested histone deacetylases (HDACs) as the potential protein target of those compounds in silico, and the predicted target was next experimentally validated by measuring the variations in the levels of p21, cyclin D and acetylation of histone H3 and tubulin. Molecular docking analysis of the title compounds with the second deacetylase domain of HDAC6 displayed high degree of shape complementarity to the binding site of the enzyme, forming multiple molecular interactions in the hydrophobic region as well as a hydrogen bond to the phenol side-chain of Tyr-782. Thus, 1,2,3-triazole derivatives appear to represent a class of novel, biologically active ligands against histone deacetylases which deserve to be further evaluated in their applications in the cancer field.

Methoxylation modifies the activity of 1,2-benzisoxazole-3-acetic acid: 6,7-dimethoxy-1,2-benzisoxazole-3-acetic acid is an auxin antagonist in cytokinin mediated processes

The insertion of a methoxy group in different positions of the aromatic ring modifies the activity of 1,2-benzisoxazole-3-acetic acid (BOAA), a specific morphogenetic compound with no activity on cell elongation or root growth. Monomethoxylation in the 4- and 7-position is critical in determining the kind of activity: 4-OMeBOAA induces stem elongation, inhibits root growth and does not improve shoot production; 7-OMeBOAA inhibits stem elongation and shoot production and is unable to induce root growth. 6,7-OMeBOAA, inactive on stem elongation and root growth, is unable to induce the expression of Pg5-GUS gene in the presence of BAP and inhibits the expression of this gene when induced by BAP plus IAA. Furthermore, 6,7-OMeBOAA inhibits completely shoot production and can therefore be regarded as an auxin antagonist in these cytokinin-mediated processes.

Low-Dose Risperidone-Induced Facial Edema in a Child with Conduct Disorder

Risperidone, a benzisoxazole derivate, is a widely prescribed antipsychotic agent that binds with high affinity to dopamine D2, serotonin type 2 (5-HT2) and al-adrenergic receptors, and causes antagonism at these receptor sites. Although risperidone has several side effects such as weight gain and sedation, edema is a very rarely observed side effect in children and adolescents. Here, we report a case of facial edema in a child with conduct disorder (CD) who was receiving low-dose of oral solution risperidone. Three days after risperidone discontinuation, the facial edema resolved entirely. Because a plausible mechanism of risperidone-induced edema remains unknown, further investigation is warranted to elucidate the risk factors and potential mechanisms of the edema.

Molecular docking and simulation studies of 3-(1-chloropiperidin-4-yl)-6-fluoro benzisoxazole 2 against VP26 and VP28 proteins of white spot syndrome virus

White spot syndrome virus (WSSV), an aquatic virus infecting shrimps and other crustaceans, is widely distributed in Asian subcontinents including India. The infection has led to a serious economic loss in shrimp farming. The WSSV genome is approximately 300 kb and codes for several proteins mediating the infection. The envelope proteins VP26 and VP28 play a major role in infection process and also in the interaction with the host cells. A comprehensive study on the viral proteins leading to the development of safe and potent antiviral therapeutic is of adverse need. The novel synthesized compound 3-(1-chloropiperidin-4-yl)-6-fluoro benzisoxazole 2 is proved to have potent antiviral activity against WSSV. The compound antiviral activity is validated in freshwater crabs (Paratelphusa hydrodomous). An in silico molecular docking and simulation analysis of the envelope proteins VP26 and VP28 with the ligand 3-(1-chloropiperidin-4-yl)-6-fluoro benzisoxazole 2 are carried out. The docking analysis reveals that the polar amino acids in the pore region of the envelope proteins were involved in the ligand binding. The influence of the ligand binding on the proteins is validated by the molecular dynamics and simulation study. These in silico approaches together demonstrate the ligand’s efficiency in preventing the trimers from exhibiting their physiological function.

Chemoselective Reductive Heterocyclization by Controlling the Binomial Architecture of Metal Particles and Acid-Base Properties of the Support

2,1-Benzisoxazoles have been selectively synthesized through reductive heterocyclization of 2-nitroacylarenes using Pt supported nanoparticles. The reaction involves a cascade process in which the first step is the reduction of the nitro group into hydroxylamine followed by heterocyclization through the nucleophilic attack of the hydroxylamine group to the carbonyl of the acyl group and further dehydration. The reaction was performed on Pt/C, Pt/TiO2, and Pt/MgO using hydrogen as the reducing agent under mild reaction conditions. The results showed that Pt/MgO was the most active and selective catalyst. The study of the influence of the crystal size of the metal on the activity and selectivity, combined with the reaction mechanism examined by in situ Fourier transform infrared spectroscopy of the adsorbed reactant, showed that the maximum activity and selectivity to the target compound can be achieved by controlling the architecture of metal particles and acid base properties of the support. The effect of temperature on selectivity, the stability of the Pt/MgO catalyst, and the scope of the reaction have been studied. Finally, reductive heterocyclization using different metals (Pd and Au) supported on MgO has also been performed.

Electrochemical reduction of 3-phenyl-1, 2-benzisoxazole 2-oxide on boron-doped diamond

The bioreduction of N-oxide compounds is the basis for the mode of action of a number of biologically active molecules. These compounds are thought to act by forming a reactive oxygen species through an intracellular reduction and subsequent redox cycling process within the organism. With these results in mind, the preliminary investigation into the electrochemical reduction of the benzisoxazole 2-oxide ring system was undertaken, with the thought that this class of compounds would reduce in a similar fashion to other N-oxide heterocycles. The electrochemical reduction of 3-phenyl-1,2-benzisoxazole 2-oxide on boron-doped diamond was studied using cyclic and square wave voltammetry as well as controlled potential electrolysis and HPLC for qualitative identification of the reaction products. It was found that the reduction proceeded with an initial quasi-reversible one-electron reduction followed by the very fast cleavage of either the endocyclic or exocyclic N-O bond. Subsequent electron transfer and protonation resulted in an overall two-electron reduction and formation of the 2-hydroxyaryl oxime and benzisoxazole. These results are analogous to those observed in the electrochemical reduction of other heterocyclic N-oxides albeit the reduction of the benzisoxazole N-oxides takes place at a more negative potential. However, these encouraging results warrant further investigation into the reduction potential of substituted benzisoxazole N-oxides as well as to elucidate and characterize the nature of the intermediate species involved.
