Scaffold hopping for identification of novel D-2 antagonist based on 3D pharmacophore modelling of illoperidone analogs

The dopamine D-2 receptor is involved in the etiology of a number of disorders, such as Parkinson’s disease, Huntington’s Chorea, tardive dyskinesia and schizophrenia. Antagonism of D-2 receptors is implicated in the treatment of various psychiatric disorders. In order to understand essential structural features required for D-2 antagonism, this research article elaborates on the generation of a four-point 3D pharmacophore model which was extracted from a series of 45 novel 3-[[(aryloxy)alkyl]piperidinyl]-1,2-benzisoxazole derivatives. The best pharmacophore model generated consisted of four PRRR features: a positively charged group (P), and three aromatic rings (R). Based on the model generated, a statistically valid 3D-QSAR with good predictability (Q(2) = 0.756) was derived. For the validation of the pharmacophore hypothesis, active compounds were docked against the 3D structure of the D-2 receptor which was constructed through homology modeling. Further, the derived pharmacophore was used as a query to search the Zinc ‘clean drug-like’ database. Hits retrieved were passed progressively through filters, such as fitness score, predicted activity and docking scores. The resulting hits present new scaffolds with a strong potential for D-2 antagonist.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 79-14-1, you can contact me at any time and look forward to more communication. Recommanded Product: 79-14-1.

Discovery of benzisoxazoles as potent inhibitors of chaperone heat shock protein 90

Heat shock protein 90 (Hsp90) is a molecular chaperone that is responsible for activating many signaling proteins and is a promising target in tumor biology. We have identified small-molecule benzisoxazole derivatives as Hsp90 inhibitors. Crystallographic studies show that these compounds bind in the ATP binding pocket interacting with the Asp93. Structure based optimization led to the identification of potent analogues, such as 13, with good biochemical profiles.

Surface-enhanced Raman scattering and density functional theoretical study of anthranil adsorbed on colloidal silver particles

Surface-enhanced Raman spectrum of anthranil (2,1-benzisoxazole) in activated silver colloid was recorded and compared with the conventional Raman spectrum. The experimentally observed Raman bands along with their corresponding infrared bands were assigned based on the results of density functional theory (DFT) calculations. The significant changes evidenced between the SER and normal Raman spectra combined with the theoretical data obtained for Ag-anthranil model systems demonstrated that this molecule is adsorbed on the colloidal silver particles through the lone pair electrons of the nitrogen atom. The contribution of the chemical mechanism to the SERS enhancement was proved by the behavior of the electronic absorption spectrum of the mixture of activated silver colloid and anthranil solution. The orientation of the adsorbed species with respect to the metal surface was also predicted.

Effect of anti-inflammatory bowel disease drug, E3040, on urate transport in rat renal brush border membrane vesicles

To confirm the assumption that 6-hydroxy-5,7-dimethyl-2-methylamino-4-(3-pyridylmethyl)benzothiazole (E3040) acts on urate reabsorption by inhibiting urate-anion exchange at the luminal membrane of renal tubules, we investigated the inhibitory effect of E3040 and its two conjugated metabolites on hydroxyl ion (OH-) gradient-dependent urate uptake into brush border membrane vesicles from rat renal cortex and compared it with other uricosuric agents. The order of potency was AA193 (5-chloro-7,8-dihydro-3-phenylfuro[2,3-g]-1,2-benzisoxazole-7-carboxylic acid)> benzbromarone > E3040 > probenecid > E3040 sulfate > E3040 glucuronide. Furthermore, kinetic analysis revealed that E3040 may be a competitive inhibitor of the OH- gradient-dependent uptake of urate into brush border membrane vesicles. (C) 2000 Elsevier Science B.V.

A Tandem Strategy for the Synthesis of 1H-Benzo[g]indazoles and Naphtho[2,1-d]isoxazoles from o-Alkynylarene Chalcones

o-Alkynylarene chalcones when treated with hydrazines and hydroxylamine in the presence of iodine gave 1H-benzo[g]indazoles and naphtho[2,1-d]isoxazoles, respectively. The transformations involve tandem oxidative cyclocondensation/electrophilic hydroarylation. The methodology was applied to quinoline-based chalcones, which also afforded the corresponding quinoline-fused benzindazole and benzisoxazole.

Zonisamide reduces nigrostriatal dopaminergic neurodegeneration in a mouse genetic model of Parkinson’s disease

Parkinson’s disease (PD) is a chronic neurodegenerative disorder characterized by the loss of nigrostriatal dopaminergic neurons and consequent motor dysfunction. Zonisamide (1,2-benzisoxazole-3-methanesulfonamide), which was originally developed as an antiepileptic drug, has been found to have therapeutic benefits for PD. However, the pharmacological mechanisms behind the beneficial actions of zonisamide in PD are not fully understood. Here, we investigated the neuroprotective effects of zonisamide on nigrostriatal dopaminergic neurons of the Engrailed mutant mouse, a genetic model of PD. Chronic administration of zonisamide in Engrailed mutant mice was shown to improve the survival of nigrostriatal dopaminergic neurons compared with that under saline treatment. In addition, dopaminergic terminals in the striatum and the motor function were improved in zonisamide-treated Engrailed mutant mice to the levels of those in control mice. To clarify the mechanism behind the neuroprotective effects of zonisamide, the contents of neurotrophic factors were determined after chronic administration of zonisamide. Brain-derived neurotrophic factor content was increased in the striatum and ventral midbrain of the zonisamide-treated mice compared to saline-treated mice. These findings imply that zonisamide reduces nigrostriatal dopaminergic cell death through brain-derived neurotrophic factor signaling and may have similar beneficial effects in human parkinsonian patients as well.

Substituent effect on the reductive N-dearylation of 3-(indol-1-yl)-1,2-benzisoxazoles by rat liver microsomes

The reductive metabolism of a series of 3-(indol-1-yl)-1,2-benzisoxazoles was examined in vitro using rat liver microsomes. 3-(Indol-1-yl)-1,2-benzisoxazole was reduced to the corresponding amidine (resulting from N-O bond cleavage) under anaerobic conditions. The reaction required viable microsomes and NADPH and was inhibited by carbon monoxide, air, and ketoconazole, suggesting the involvement of cytochrome P450 enzymes. The amidine was subsequently nonenzymatically hydrolyzed to 1-salicylindole, which in turn was hydrolyzed to indole. Addition of electron-withdrawing substituents (Cl-, MeSO2-) at the 6-position of the benzisoxazole ring resulted in a significant increase in the rate of substrate reduction. Introduction of electron-withdrawing substituents on the indole ring likewise increased the rate of substrate consumption but caused a substituent-dependent shift of the site of bond cleavage from the 1,2-isoxazole N-O bond to the C-N bond linking the 1,2-benzisoxazole to the indole moiety. In the case of 3-(2-chloro-3-methanesulfoxylindol-1-yl)-1,2-benzisoxazole, C-N bond cleavage was nearly quantitative, and products resulting from N-O bond reduction were not observed. The overall rates of 3-(indol-1-yl)-1,2-benzisoxazoles reduction were found to be substrate concentration-dependent and observed Michaelis-Menten-type behavior. The apparent V-max of substrate reduction by rat liver microsomes correlated negatively with the free energy of the lowest unoccupied molecular orbitals (E-LUMO) calculated semiempirically using a parameterized model 3 (PM3), and suggested that the initial electron transfer was rate-determining and that the E-LUMO could be used as an indication of the susceptibility of 1,2-isoxazoles to undergo reductive metabolism.

Zonisamide suppresses the tonic phase but not the clonic phase of generalized seizures in developing rats

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.

Risperidone as a treatment for Tourette’s syndrome

Background: An open-label trial was performed to assess the efficacy and safety of risperidone, a benzisoxazole derivative with potent D-2 and 5-HT2 antagonism, for treatment of Tourette’s syndrome. Method: Thirty-eight patients with Tourette’s syndrome volunteered to take risperidone for treatment of their tics. All patients had failed to respond adequately to conventional treatments (with neuroleptics such as haloperidol and/or with the alpha(2)-adrenergic agonist clonidine) or had suffered from intolerable side effects from such treatments. Patients were rated for tic severity by the Yale Global Tic Severity Scale (YGTSS) before treatment and after 1 month of treatment with risperidone. Patients were monitored carefully for side effects and clinical response. Results: Of the 38 patients, 8 discontinued risperidone treatment before the end of the trial because of intolerable side effects. At the end of the 4-week trial, 22 patients (58%) were improved, 7 patients (18%) had no appreciable change in their symptoms, and 1 patient (3%) had a documented worsening of tics. Doses of risperidone at the end of the trial ranged from 0.5 mg to 9 mg/day (mean = 2.7 mg/day). Conclusion: This open clinical trial suggests that risperidone may be a promising alternative to conventional medications used for treating the symptoms of Tourette’s syndrome.
