Different 7-amino-3-methyl-5-(3′-aryl prop-2′-enoyl)-1,2-benzisoxazoles were synthesized by the interaction of appropriate 5-acetyl-7-amino-3-methyl-1,2-benzisoxazole with different aromatic aldehydes using piperidine. Tetra-O-acetyl-alpha-D-glucopyranosyl bromide was prepared by the reaction of powdered glucose pentaacetate and bromine in the presence of chloroform. Condensation of tetra-O-acetyl-alpha-D-glucopyranosyl bromide with 7-amino-3-methyl-5-(3′-aryl prop-2′-enoyl)-1,2-benzisoxazoles furnished 7-amino-(2,3,4,6-tetra-O-acetyl-beta-D-glucopyranosyl)-3-methyl-5-(3′-aryl prop-2′-enoyl)-1,2-benzisoxazoles which on deprotection gave 7-amino-(beta-D-glucopyranosyl)-3-methyl-5-(3′-aryl prop-2′-enoyl)-1,2-benzisoxazoles. Polarographic studies revealed the presence of reducible groups with distinguished E-1/2 values. All compounds were screened for antimicrobial activities, and some compounds showed potent antibacterial and antifungal activities. [GRAPHICS]

Oxadisilole-fused benzisoxazoles or naphthisoxazoles were obtained through 1,3-dipolar cycloaddition of arynes with nitrile oxides in good yields at room temperature. Key to the procedure is the simultaneous in situ generation of reactive nitrile oxides from arenecarbohydroximoyl chlorides and aryne reactants from benzobis(oxadisilole) or 2,3-naphthoxadisilole. One oxadisilole-fused benzisoxazole is a new precursor of a benzyne formed by a phenyliodination/fluoride-induced elimination protocol. By using this benzyne, cycloadducts were synthesized in good yields. The de-oxadisilole reaction of some of the oxadisilole-fused benzisoxazoles could be easily conducted with a 1.0 M solution of tetrabutylammonium fluoride in THF at room temperature.

A rigidification strategy was applied to the preclinical candidate donecopride, an acetylcholinesterase inhibitor possessing 5-HT4R agonist activity. Inspired by promising bioactive benzisoxazole compounds, we have conducted a pharmacomodulation study to generate a novel series of multitarget directed ligands. The chemical synthesis of the ligand was optimized and compounds were evaluated in vitro against each target and in cellulo. Structure-activity relationship was supported by docking analysis in human acetylcholinesterase binding site. Among the synthesized compounds, we have identified a novel hybrid 32a (3-[2-[1-(cyclohexylmethyl)-4-piperidyl]ethyl]-4-methoxy-1,2-benzoxazole) able to display nanomolar acetylcholinesterase inhibitory effects and nanomolar Ki for 5-HT4R.

Liver X receptors (LXRs) are nuclear receptors that are central regulators of cholesterol homeostasis, and synthetic LXR agonists have shown promise as promoters of reverse cholesterol transport and anti-inflammatory agents. Here, we present three X-ray structures of three different agonists bound to the ligand binding domain of LXR alpha. These compounds are GW3965, F(3)methylAA, and a benzisoxazole urea, and we show that these diverse chemical scaffolds address common structural themes, leading to high binding affinity for LXR. Our structures show the LXR ligand binding domain in its homodimeric form, an arrangement previously thought to be stereochemically difficult. A comparison with existing structures of the LXR beta homodimer and LXR alpha:RXR (retinoid X receptor) heterodimers explains differences in dimer affinity and leads us to propose a model for allosteric activation in nuclear receptor dimers, in which an unactivated RXR partner provides an inhibitory tail wrap to the cofactor binding pocket of LXR.

Au(I)-catalyzed selective reactions of Et- and Bu-t-substituted propiolates (1a and 1a’) with 1,2-benzisoxazole(2a) provide a new strategy for purposefully access to desired bioactive heterocycles. Using DFT calculations, we have systematically investigated the detailed mechanisms and origins of the ester-controlled chemoselectivity. The calculated results indicated that both reactions are initiated by LAu+ pi-coordination, N nucleophilic attack, and NTf2–assisted stepwise H-shift, generating a nitrilium species identified as a common and requisite intermediate, which is significantly different from the experimentally proposed 6-alkoxy-1,3-oxazin-1-ium intermediate. Starting from the nitrilium intermediate, the newly established nucleophilic cyclization, alkene release, and NTf2–assisted stepwise protodeauration provides [4 + 2]-annulation product P-1, while the nitrilum dissociation, O nucleophilic attack, and NTf2–assisted stepwise protodeauration generates Michael-type product P-2. Further explorations showed that Bu-t-controlled chemoselectivity of P-1 over P-2 can be attributed to the energy favorable aromaticity of selective-determining nucleophilic cyclization TS. With substitution of Bu-t by Et group, the reversal of chemoselectivity to P-2 formation might be closely related to the presence of extremely unstable Et cation in ethylene release TS leading to P-1.

Chemical Research Letters, May 2021. In classical electrochemical theory, both the electron transfer rate and the adsorption of reactants at the electrode control the electrochemical reaction. In an article, author is Pokhodylo, Nazariy T., once mentioned the application of 1191-25-9, Name is 6-Hydroxyhexanoic acid, molecular formula is C6H12O3, molecular weight is 132.1577, MDL number is MFCD00046560, category is benzisoxazole. Now introduce a scientific discovery about this category, Safety of 6-Hydroxyhexanoic acid.

Reaction of 1-nitro-4-(1,2,3-triazolyl/tetrazolyl)benzenes with arylacetonitriles in an alcoholic medium in the presence of excess alkali gives novel 2,1-benzisoxazoles. These findings indicate a high reactivity of nitroarenes activated by the azole ring due to their electron-deficient character. Moreover, it was found that annulation of the isoxazole ring occurred regioselectively in disubstituted nitroarenes. In the case of 1-(4-nitrophenyl)-1H-tetrazole, the tetrazole ring cleaved faster than the sigma(H)-adduct was formed.

Objectives: Zonisamide (ZnS) is a new generation antiepileptic agent used in the treatment of epilepsy patients with partial and generalized seizures. In this study, we aim to investigate the safety and efficacy of ZnS in the treatment of patients with refractory epilepsy who were being followed. Methods: Forty-five refractory epilepsy patients who received ZnS treatment were included in this study. Patients who received ZnS treatment for less than six months were excluded. Age, sex, types of seizures, examination findings, magnetic resonance imaging and electroencephalography findings, concurrent use of non-ZnS antiepileptic drugs, decrease in the seizure frequency and side effects of the drug were recorded. Results: Thirty-nine patients, whose mean age was 34.3 +/- 9.3 years, were evaluated. Complex partial seizures (CPS) and generalized tonic-clonic seizure (GTCS) were observed in 74.4% of the patients, whereas 10.3% had GTCS alone, 7.7% had CPS alone, 5.2% had GTCS and myoclonia and 2.6% of them had absence and myoclonia. In the follow-up, treatment was observed to be discontinued in 19 of the 39 patients due to drug side effects, or where there was an increase, or no change, in seizure frequency. Twenty patients responded to treatment. Seizure frequency was decreased by 25% in one patient; 50% in five patients, and 75% in seven patients. Three patients were seizure-free. Although there was no change in seizure frequency, seizure duration was shortened in four patients. Treatment-responsive patients were using ZnS at doses that ranged from 100 to 400 mg/day for 7 to 80 months. Conclusion: ZnS is a safe, tolerable and effective option for the additional treatment of refractory epilepsy patients at our center.

Electric Literature of 99-14-9, Because enzymes can increase reaction rates by enormous factors and tend to be very specific, typically producing only a single product in quantitative yield, they are the focus of active research.you can also check out more blogs about 99-14-9.

The widespread use of toxic phosphates and phosphonates as insecticides, and their use as chemical weapons, has led to investigation of fast detoxification and decontamination methods. Micelles, microemulsions, cyclodextrines and liposomes have been used to accelerate phosphate ester decomposition by nucleophiles. Here, hydrolysis, methanolysis and hexanolysis of Tris-p-nitrophenyl phosphate (TNPP), a model for reactive phosphate esters. were studied in homogeneous phase, aqueous and reverse micelles. Kinetic micellar effects were quantitatively analyzed using pseudo-phase models. TNPP hydrolysis was catalyzed by cetyltrimethylammonium chloride (CTAC), cetyltrimethylammonium bromide (CTAB). and hexadecylammonium propanesulfonate (HPS), micelles by factors of five, CTAC, and three. CTAB, HPS, respectively. The calculated rate constants for spontaneous and acetate-catalyzed hydrolysis in the micellar phase were significantly higher than those in the aqueous phase. While in water and in methanol the effect of the acetate cation was negligible, the catalytic efficiency of acetate for hexanolysis depended on the nature of the cation with the K+ salt being ca. 20 times more efficient than the tetraethylammonium salt in non-polar solvents. Sodium dodecylsulfate, SDS. micelles inhibited TNPP hydrolysis by a factor of eigth. Reverse micelles of CTAB in n-hexanol/isooctane (10:90, v/v) did not catalyze TNPP hydrolysis, but changed the bis-p-nitrophenyl phosphate/hexyl-bis-p-nitrophenylphosphate product ratio depending of CTAB concentration and water/detergent ratio.
