5-ARYLOXYBENZISOXAZOLE ESTERS – SYNTHESIS AND HERBICIDAL ACTIVITY

A series of benzisoxazole glycolate and acetate ester diphenyl ethers were prepared. The preparation of intermediate 5-hydroxybenzisoxazoleacetic acid from 4,6-dihydroxycoumarin was improved by reaction in the presence of excess hydroxylamine hydrochloride. The resultant diphenyl ether herbicides were potent total vegetation control pre- and postemergence herbicides.

Application of 298-12-4, 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 298-12-4.

Highly efficient catalysis of the Kemp elimination in the cavity of a cubic coordination cage

The hollow cavities of coordination cages can provide an environment for enzyme-like catalytic reactions of small-molecule guests. Here, we report a new example (catalysis of the Kemp elimination reaction of benzisoxazole with hydroxide to form 2-cyanophenolate) in the cavity of a water-soluble M8L12 coordination cage, with two features of particular interest. First, the rate enhancement is among the largest observed to date: at pD 8.5, the value of k(cat)/k(uncat) is 2 x 10(5), due to the accumulation of a high concentration of partially desolvated hydroxide ions around the bound guest arising from ionpairing with the 16+ cage. Second, the catalysis is based on two orthogonal interactions: (1) hydrophobic binding of benzisoxazole in the cavity and (2) polar binding of hydroxide ions to sites on the cage surface, both of which were established by competition experiments.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 546-89-4 is helpful to your research. Quality Control of Lithiumacetate.

Zonisamide as a Treatment for Partial Epileptic Seizures: A Systematic Review

Although the majority of people with epilepsy have a good prognosis and their seizures can be well controlled with pharmacotherapy, up to one-third of patients can develop drug-resistant epilepsy, especially those patients with partial seizures. This unmet need has driven considerable efforts over the last few decades aimed at developing and testing newer antiepileptic agents to improve seizure control. One of the most promising antiepileptic drugs of the new generation is zonisamide, a benzisoxazole derivative chemically unrelated to other anticonvulsant agents. In this article, the authors present the results of a systematic literature review summarizing the current evidence on the efficacy and tolerability of zonisamide for the treatment of partial seizures. Of particular interest within this updated review are the recent data on the use of zonisamide as monotherapy, as they might open new therapeutic avenues.

Novel indole-based peroxisome proliferator-activated receptor agonists: Design, SAR, structural biology, and biological activities

The synthesis and structure-activity relationship studies of novel indole derivatives as peroxisome proliferator-activated receptor (PPAR) agonists are reported. Indole, a druglike scaffold, was studied as a core skeleton for the acidic head part of PPAR agonists. The structural features (acidic head, substitution on indole, and linker) were optimized first, by keeping benzisoxazole as the tail part, based on binding and functional activity at PPAR gamma protein. The variations in the tail part, by introducing various heteroaromatic ring systems, were then studied. In vitro evaluation led to identification of a novel series of indole compounds with a benzisoxazole tail as potent PPAR agonists with the lead compound 14 (BPR1H036) displaying an excellent pharmacokinetic profile in BALB/c mice and an efficacious glucose lowering activity in KKA(y) mice. Structural biology studies of 14 showed that the indole ring contributes strong hydrophobic interactions with PPAR gamma and could be an important moiety for the binding to the protein.

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.

REDUCTIVE METABOLISM OF THE ANTICONVULSANT AGENT ZONISAMIDE, A 1,2-BENZISOXAZOLE DERIVATIVE

1. The metabolism of zonisamide in vitro was characterized through aerobic and anaerobic incubations with rat liver subcellular fractions and cultured gastrointestinal microflora. 2. Zonisamide reacted with rat hepatic microsomal cytochrome P-450 and exhibited a Type I binding spectrum. 3. Metabolism of zonisamide in vitro by hepatic subcellular fractions and cultured gastrointestinal flora produced a single metabolite, 2-(sulphamoylacetyl)-phenol (2-SMAP), by reductive cleavage of the 1,2-benzisoxazole ring. 4. The reductive metabolism of zonisamide was primarily mediated by microsomal cytochrome P-450. The soluble fraction enhanced reduction when combined with the microsomal fraction but itself possessed only weak reductive activity. 5. Reduction of zonisamide by the most enzymically active liver fractions required NADPH, was stimulated by FMN and SKF-525A, and was inhibited by CO or air, as well as by n-octylamine. 6. Unlike their involvement in the reduction of numerous nitro, azo, and N-oxide compounds, cultured aerobic and anaerobic intestinal flora were not principally involved in the reduction of zonisamide.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 298-12-4, you can contact me at any time and look forward to more communication. Application In Synthesis of 2-Oxoacetic acid.

BRIDGED GAMMA-CARBOLINES AND DERIVATIVES POSSESSING SELECTIVE AND COMBINED AFFINITY FOR 5-HT2 AND D(2)-RECEPTORS

A series of 5,6,7,8,9,10-hexahydro-7,10-iminocyclohept[b]indoles and 6,7,8,9,10,11-hexahydro-7,-11-imino-5H-cyclooct[b]indoles was prepared. Structural modifications of the lead compound, 11-[4-(4-fluorobenzoyl)propyl]-5,6,7,8,9,10-hexahydro-7,10-iminocyclohept[b]indole (5, K(i) = 0.82 nM vs [H-3]ketanserin) enabled the identification of the functionality necessary for high affinity at serotonin 5-HT2 and dopamine D2 receptors in ligand binding studies. The indole ring, as well as the benzoyl or isosteric benzisoxazole moiety, were essential for high affinity. Variations of the length of the side chains resulted in ligands having either selective affinity for the 5-HT2 receptor or a combination of 5-HT2 and D2 affinity. In vivo binding studies were performed on selected members in this series. The most potent member, 2-fluoro-11-[4-(4-fluorobenzoyl)butyl]-5,6,7,8,9,-10-hexahydro-7,10-iminocyclohept[b]indole (36) had an ED50 of <1 mg/kg at the 5-HT2 and D2 receptors following oral administration.

RAT-LIVER MICROSOMAL CYTOCHROME-P-450 RESPONSIBLE FOR REDUCTIVE METABOLISM OF ZONISAMIDE

The reductive metabolism of 1,2-benzisoxazole-3-methanesulfonamide (zonisamide) to 2-sulfamoylacetylphenol (SMAP) was observed in liver microsomes from female rats, as well as male rats, but the SMAP-producing activity in female rats was 4-fold lower than that found in male rats. In addition, the reductive metabolism of zonisamide in liver microsomes was induced by the treatment of male rats with phenobarbital. However, the SMAP-producing activity did not correlate positively with the amounts of P-450 2B1 and P-450 2C11 immunochemically determined. In contrast, the reductive metabolism of zonisamide was also found to be induced by the pretreatment of male rats with pregnenolone 16alpha-carbonitrile, triacetyloleandomycin, and dexamethasone. Furthermore, the SMAP-producing activity correlated highly with the amount of P-450 cross-reactive with antihuman P-450 3A4 antibody, suggesting that P-450 3A1/2 may function in the reductive metabolism of zonisamide. In addition, the P-450 PCNa (3A2) exhibited the SMAP-producing activity in a reconstituted system. The antihuman P-450 3A4 antibody inhibited markedly the formation of SMAP from zonisamide in male rat liver microsomes. These results indicate that cytochrome(s) P-450 belonging to P-450 3A subfamily may be predominantly responsible for the reductive metabolism of zonisamide in rat liver microsomes.

Non-cross-linked and cross-linked poly(alkylmethyldiallylammoniumhalides): synthesis and aggregation behavior

Hydrophobically modified polyelectrolytes (polysoaps) are a unique class of water-soluble polymers containing distinct hydrophobic and hydrophilic regions. Above a certain concentration, polysoaps form intramolecular and intermolecular aggregates in aqueous solution. They have attracted much attention not only for their ability to mimic some functions demonstrated by biopolymers but also for their important industrial applications. This review highlights some interesting features of novel non-cross-linked and cross-linked poly(alkylmethyldiallyl-ammonium halides) that have been described in recent years.
