Is subnanomolar binding affinity required for the in vivo imaging of acetylcholinesterase? Studies on F-18-labeled G379

Acetylcholinesterase (AChE) is an important cholinergic marker of Alzheimer’s disease (AD) and shows reduced activity in postmortem AD brain tissues. 1-(4-Fluorobenzyl)-4-[(5,6-dimethoxy-l-oxoindan-2-fluoro-2-yl)methyl]piperidine (G379, 1), an AChE inhibitor with a subnanomolar IC50 (0.56 nM), was prepared as a F-18-labeled radioligand ([F-18]1) and evaluated in mice. Metabolism studies of [F-18]1 showed no metabolites in the mouse brain. Tissue distribution studies demonstrated its uniform regional distribution in the mouse brain, suggesting that this radioligand is not suitable for the in vivo imaging of AChE. This result along with reports on radiolabeled AT-benzylpiperidine lactam benzisoxazole (IC50 < 1 nM) and other radiolabeled benzylpiperidme derivatives (IC50 > 1 nM) suggested that a subnanornolar IC50 may not be the only important factor in determining the suitability of a radioligand for in Vivo Studies of AChE.

Iloperidone: a new benzisoxazole atypical antipsychotic drug. Is it novel enough to impact the crowded atypical antipsychotic market?

Iloperidone is a new-generation atypical antipsychotic agent, acting as a serotonin/dopamine (5-HT2A/D-2) antagonist, under development by Vanda Pharmaceuticals for the treatment of schizophrenia, bipolar disorder and other psychiatric conditions. Chemically, iloperidone is a benzisoxazole, like risperidone, and shows a multiple receptor binding profile, sharing this feature with the other atypical antipsychotic agents. Administered orally, the drug is highly bound to plasma proteins and extensively metabolised. Several clinical trials have been carried out, to check efficacy, safety and side effects. in order to introduce iloperidone as an agent for the treatment of schizophrenia, a short overview of the disease and of the most important antipsychotic drugs available or under development will be reported. Iloperidone pharmacokinetics and pharmacodynamics are presented herein, together with an evaluation of clinical safety and efficacy results.

Isoxazole -> benzisoxazole rearrangement promoted cascade reactions affording stereodefined polycycles

[GRAPHICS] A new chemo-, regio-, and stereoselective cascade reaction features a novel isoxazole –> benzisoxazole rearrangement and affords highly functionalized, differentially protected compounds. The products of this reaction are directly converted to a number of complex, structurally diverse polycyclic molecules. These transformations highlight the unique chemistry inherent to readily prepared fused isoxazoles.

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.

In a patnet, author is WANG, GJ, once mentioned the new application about 68-04-2.

A family of non-cross-linked and cross-linked copolymers containing decyl, octyl, and hexyl groups as side chains ((CL)-CopolC1-10, (CL)-CopolC1-8, and (CL)-CopolC1-6, respectively) were synthesized by radical-initiated cyclocopolymerization of alkylmethyldiallylammonium bromide monomers without and with a small amount of N,N’-methylenebisacrylamide as a cross-linking agent in aqueous solution. Their H-1 NMR and IR spectra indicated the presence of five-membered rings cross-linked without and with N,N’-methylenebisacrylamide in the macromolecules. Viscosity measurements showed that the cross-linked copolymers exhibit a larger reduced viscosity in aqueous solution with increasing cross-linking agent content in the copolymers. For(CL)-CopolC1-10, the conformational transition to compact coils was indicated by changes of the reduced viscosity in dilute aqueous solutions. At higher concentrations, intermolecular aggregation was also revealed and increased with increasing the percentage of cross-linking for CL-CopolC1-10. (CL)-CopolC1-8 and (CL)-CopolC1-6 showed extented molecular dimensions in aqueous solution. The hydrophobic microdomains of the non-cross-linked and cross-linked copolymers were probed by hypsochromic shifts of the long-wavelength absorption band of Methyl Orange as a solvatochromic agent, noncovalently bound to the macromolecule. The unimolecular decarboxylation of 6-nitrobenzisox-azole-3-carboxylate (6-NBIC), catalyzed by these copolymers in aqueous solution, was used as a model reaction to study the influence of polysoap microenviroment on reactivity. Depending on the hydrophobic group content, (CL)-CopolC1-10 led to a remarkably large rate enhancement, whereas (CL)-CopolC1-8 induced only modest rate acceleration for the decarboxylation of 6-NBIC. A small rate enhancement was observed in the presence of(CL)-CopolC1-6. The decarboxylation rate is also sensitive to changes of the percentage of cross-linking in the macromolecules. A maximum in rate constant was found at about 0.2% (w/w) cross-linking agent for CL-CopolC1-10 and at about 0.4% (w/w) for CL-CopolC1-8 in plots of the rate constant vs cross-linking agent content.

Rather efficient catalysis of the decomposition of 5-nitro-benzisoxazole to the cyanophenol was observed with antibodies elicited against a cationic hapten structurally unrelated to the benzisoxazole substrate. The rate enhancement by the most active antibody is better than 10(4) and the reaction is catalyzed by a carboxylate group associated with a hydrophobic binding site. (C) 1997 Elsevier Science Ltd.

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.
