Novel benzofuran-2-carboxylic acids, exemplified by 29, 38 and 39, have been discovered as potent Pim-1 inhibitors using fragment based screening followed by X-ray structure guided medicinal chemistry optimization. The compounds demonstrate potent inhibition against Pim-1 and Pim-2 in enzyme assays. Compound 29 has been tested in the Ambit 442 kinase panel and demonstrates good selectivity for the Pim kinase family. X-ray structures of the inhibitor/Pim-1 binding complex reveal important salt-bridge and hydrogen bond interactions mediated by the compound’s carboxylic acid and amino groups.

Synthetic Route of 3199-61-9, The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.3199-61-9, Name is Ethyl benzofuran-2-carboxylate, molecular formula is C11H10O3. In a Article，once mentioned of 3199-61-9

A novel series of shikonin-benzo[b]furan derivatives were designed and synthesized as tubulin polymerization inhibitors, and their biological activities were evaluated. Most compounds revealed the comparable anti-proliferation activities against the cancer cell lines to that of shikonin and simultaneously low cytotoxicity to non-cancer cells. Among them, compound 6c displayed powerful anti-cancer activity with the IC50 value of 0.18 muM against HT29 cells, which was significantly better than that of the reference drugs shikonin and CA-4. What’s more, 6c could inhibit tubulin polymerization and compete with [3H] colchicine in binding to tubulin. Further biological studies depicted that 6c can induce cell apoptosis and cell mitochondria depolarize, regulate the expression of apoptosis related proteins in HT29 cells. Besides, 6c actuated the HT29 cell cycle arrest at G2/M phase, and influenced the expression of the cell-cycle related protein. Moreover, 6c displayed potent inhibition on cell migration and tube formation that contributes to the antiangiogenesis. These results prompt us to consider 6c as a potential tubulin polymerization inhibitor and is worthy for further study.

Application of 4265-25-2, Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other? The answer is in thermodynamics and kinetics.In a document type is Article, and a compound is mentioned, 4265-25-2, 2-Methylbenzofuran, introducing its new discovery.

The BTL (biomass-to-liquid) process is an attractive process that produces liquid biofuels from biomass. The FT (Fisher-Tropsch) process is used to produce synfuels such as diesel and gasoline from gasified biomass. However, the H2S (hydrogen sulfide), COS (carbonyl sulfide) and CO2 (carbon dioxide) in the syngas that are produced from the biomass gasifiers cause a decrease of the conversion efficiency and deactivates the catalyst that is used in the FT process. To remove the acid gases, a pilot-scale methanol absorption tower producing diesel at a rate of 1BPD (barrel per day) was developed, and the removal characteristics of the acid gases were determined. A total operation time of 500h was achieved after several campaigns. The average syngas flow rate at the inlet of methanol absorption tower ranged from 300 to 800L/min. The methanol absorption tower efficiently removed H2S from 30ppmV to less than 1ppmV and COS from 2ppmV to less than 1ppmV with a removal of CO2 from 20% to 5%. The outlet gas composition adhered to the guidelines for FT reactors. No remaining sulfurous components were found, and the tar component was analyzed in the spent methanol after long-term operations.

We present the utilization of a heterogeneous catalyst comprised of Pd nanoparticles supported on aminopropyl-functionalized siliceous mesocellular foam (Pd0-AmP-MCF) for the selective hydrogenation of aromatic, aliphatic, and heterocyclic nitro compounds to the corresponding amines. In general, the catalytic protocol exclusively affords the desired amine products in excellent yields within short reaction times with the reactions performed at room temperature under ambient pressure of H2. Moreover, the reported Pd nanocatalyst displayed excellent structural integrity for this transformation as it could be recycled multiple times without any observable loss of activity or leaching of metal. In addition, the Pd nanocatalyst could be easily integrated into a continuous-flow device and used for the hydrogenation of 4-nitroanisole on a 2.5 g scale, where the product p-anisidine was obtained in 95% yield within 2 h with a Pd content of less than 1 ppm.

Application of 16859-59-9, The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.16859-59-9, Name is 3-Hydroxyisobenzofuran-1(3H)-one, molecular formula is C8H6O3. In a Article，once mentioned of 16859-59-9

Ring chain tautomerism with slow interconversion (compared with the NMR timescale) was observed in solutions of 2-(2,2-dicyano-1-methylethenyl)benzoic acid (3e), obtained by Knoevenagel condensation of 2-acetylbenzoic acid with malononitrile, forming the ring tautomer 3-dicyanomethyl-3-methylphthalide (4e) in admixture with 3e. Similar condensations of 2-formylbenzoic acid with methyl cyanoacetate or malononitrile give 2-(2-cyano-2-methoxycarbonyl-ethenyl)benzoic acid (3b) and 2-(2,2-dicyanoethenyl)benzoic acid (3d), respectively, which in solution also exhibit the same tautomerism to give the ring tautomers, 3-(cyanomethoxycarbonylmethyl)phthalide (4b) and 3-(dicyanomethyl)phthalide (4d), respectively. Condensation of 2-formylbenzoic acid with dimethyl malonate gave only the ring compound, 3-(dimethoxycarbonylmethyl)-phthalide (4a). Attempts to synthezise 2-(2-cyano-2-methoxycarbonyl-1-methylethenyl)benzoic acid (3c) by methylation of the trimethyl silylester of 3b with diazomethane led to the ring form of 3c, viz. 3-cyanomethoxycarbonylmethyl-3-methylphthalide (4c) as an equimolar mixture of two diastereomers. No tautomerism was observed when the benzene ring was replaced by a thiophene ring (7a, 7b and 8) or an aliphatic double bond (9). Solid state spectra (IR and NMR) indicated that all compounds carrying two cyano groups at the double bond, except the aliphatic compound 9, were in the open-chain form, while all the others were in the ring form. Equilibrium studies for compound (3e?4e) indicated increased stability for the chain form 4e with increasing solvent polarity. Determination of the free energy change, DeltaG, and of the free energy of activation, DeltaG?, for the tautomerization in deuteriochloroform (using 1H NMR spectroscopy) indicated that, in this solvent, a concerted process from the starting material 3e to the anion of 4e is taking place. It is also postulated that a similar reaction path is followed in the other solvents used in this investigation, all belonging to the solvent class ‘protophobic dipolar aprotic solvents’. Acta Chemica Scandinavica 1998.
