4265-25-2, Name is 2-Methylbenzofuran, belongs to benzofurans compound, is a common compound. Recommanded Product: 2-MethylbenzofuranIn an article, once mentioned the new application about 4265-25-2.

A novel series of 4,5,6,7-tetrahydro-1H-benzimidazole derivatives 4, 5, 6 and 7 was prepared and evaluated for activities as 5-hydroxytryptamine (5- HT3) receptor antagonists which may be useful for the treatment of irritable bowel syndrome (IBS) as well as nausea and vomiting associated with cancer chemotherapy. These compounds were designed by modifying the aromatic- carbonyl part of N-(2-methoxyphenyl)-4,5,6,7-tetrahydro-1H-5- benzimidazolylcarboxamide 3, leaving the imidazole moiety unchanged as the amine part. The indole derivatives 7d, g, h and indolizine derivatives 7k, 1 were found to be highly potent on the von Bezold-Jarisch (B.J.) reflex test with ID50 values of below 0.1 mug/kg, and the indoline derivative 6c, indole derivatives 7a, d, g, benzofurane derivative 7j and indolizine derivative 7k were observed to be very potent on the colonic contraction with IC50 values of below 0.1 muM. In particular, 71 was the most potent on the B.J. reflex (ID50 = 0.018 mug/kg), approximately 200 and 50 times more potent than ondansetron 1 and granisetron 2, and 7k was the most potent on the colonic contraction (IC50 = 0.011 muM), approximately 70 and 6 times more potent than 1 and 2, respectively.

One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, Product Details of 496-41-3, such as the rate of change in the concentration of reactants or products with time.In a article, mentioned the application of 496-41-3, Name is Benzofuran-2-carboxylic acid, molecular formula is C9H6O3

The development of a solution-phase approach to the rapid, parallel synthesis of highly functionalized piperazinones in only four steps starting from N-Boc-iminodiacetic acid is detailed. The efforts represent the extension of the solution-phase synthesis of combinatorial libraries from N-Boc-iminodiacetic acid to non-amide-based libraries where simple liquid-liquid extractions are employed to purify all reaction products. This methodology was applied to the synthesis of a diverse 150-member library with substituents in three positions of the piperazinone core. Screening results from a luciferase reporter assay indicate that a number of library members are novel repressors of LEF-1/beta-catenin-mediated transcription, and may be effective agents against colorectal tumors. Two secondary libraries (100 members each) designed from these lead structures were synthesized and screened, providing additional active agents and insight into key structure-activity relationships in the series. These compounds represent only the second class of small molecules which repress transcription of reporter genes containing LEF-1 responsive elements, and the first group not based on DNA minor-groove-binding agents.

The logarithm of capacity factors (log k’) previously measured from the reversed-phase high-performance liquid chromatography (RP-HPLC) and the octanol-water partition coefficients (log P) of a mixed set of substituted benzene, furan, benzofuran, pyrrole, 1-Me-pyrrole, indole, and N-methyl indole derivatives are correlated with the descriptors obtained from their three-dimensional structures for a mixed set of compounds.

The answer is in thermodynamics and kinetics.In a document type is Article, and a compound is mentioned, 4265-16-1, Benzo[b]furan-2-carboxaldehyde, introducing its new discovery.

A simple synthesis method of nitriles from corresponding aldehydes by electrochemical oxidation was developed with ammonium acetate as the nitrogen source and 4-acetamido- 2,2,6,6-tetramethylpiperidinyl-l-oxy (4-AcNH-TEMPO) as the catalyst. Cyclic voltammetry was performed to investigate the electrocatalytic activity of 4-AcNH-TEMPO for the conversion of benzaldehyde to benzonitrile. On the basis of in situ FTIR data and cyclic voltammetry experiments, a reaction mechanism, involving the redox of 4-AcNH-TEMPO and the generation of intermediate imine during the reaction, was proposed. This electrocatalytic reaction system provided an efficient protocol for synthesis of aromatic nitriles at room temperature with moderate to high yields.

In the present study we have made an attempt to synthesize novel benzofuran derivatives and evaluate them for anticancer screening. First, 2-carbethoxy-3 (2H) benzofuranone (2) was prepared by the condensation of ethyl bromomalonate with methyl salicylate (1) in presence of anhydrous potassium carbonate. Treatment of 2- carbethoxy-3 (2H) benzofuranone (2) with dimethylsulphate in presence of anhydrous potassium carbonate afforded 2-carbethoxy-3-methoxy benzofuranone (3). 2- Carbethoxy-3-methoxy benzofuranone (3) on treatment with hydrazine hydrate gave 3-methoxybenzofuran-2-carbohydrazide (4) and then condensation of 3- methoxybenzofuran-2-carbohydrazide (4) with various substituted benzaldehydes led to a novel series of benzofuran derivatives (5a-k). The synthesized compounds were analyzed by physical and analytical data. The synthesized compounds were evaluated for their short-term anticancer activity. The synthesized benzofuran derivative possessed significant cytotoxic activity against Ehrlich’s Ascites Carcinoma (EAC) cell lines and HEP2 cell line by Sulforhodamine B assay.

An efficient and user-friendly palladium(II) precatalyst, POxAP (post-oxidative-addition precatalyst), was identified for use in Fukuyama cross-coupling reactions. Suitable for storage under air, the POxAP precatalyst allowed reaction between thioesters and organozinc reagents with turnover numbers of ?90000. A series of 23 ketones were obtained with yields ranging from 53 to 99%. As proof of efficacy, an alternative approach was developed for the synthesis of a key precursor of the natural product isoprekinamycin.

Synthetic Route of 652-39-1, Catalysts function by providing an alternate reaction mechanism that has a lower activation energy than would be found in the absence of the catalyst. In some cases, the catalyzed mechanism may include additional steps.In a article, 652-39-1, molcular formula is C8H3FO3, introducing its new discovery.

This paper describes the synthesis of N-pyridinyl(alkyl)phthalimides related to N-phenyl-4,5,6,7-tetrafluorophthalimides known to be inhibitors of tumour necrosis factor-alpha (TNFalpha) production. Pharmacomodulation at the phthalimidic nitrogen led to the selection of two pharmacophoric fragments (2,4-lutidinyl and beta-picolyl), allowing significant inhibition of TNFalpha production (compounds 12 and 17). Variation of the substituents linked to the homocycle of their phthalimide scaffold indicated that high (TNFalpha production) inhibitory potency could be achieved, notably by 5-fluoro, 4- or 5-nitro, 5-amino and especially tetrafluoro substitution. The most active compound, N-(pyridin-3-ylmethyl)-4,5,6,7-tetrafluorophthalimide (32) (84% inhibition at 10 muM), also produced an anti-oedematous effect in the PMA-induced mouse-ear swelling test. Although less active than dexamethasone, it exerted a marked reduction in ear thickness after oral administration (63% vs. 85% for dexamethasone at 0.2 mM kg-1) and remained efficient after topical application (46% vs. 96% for the dexamethasone). It also induced potent inhibition in the rat carrageenan foot oedema test with an ID50 (0.14 muM kg-1) comparable with that of N-(2,6-diisopropylphenyl)phthalimide (4) (0.15 muM kg-1).

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 652-39-1 is helpful to your research. Synthetic Route of 652-39-1
