5-hydroxymethylfurfural (HMF) is one of the most important renewable platform-chemicals, a very valuable precursor for the synthesis of bio-fuels and bio-products. In this work, the hydrogenation of HMF to two furan diols, 2,5-bis(hydroxymethyl)furan (BHMF) and 2,5-bis(hydroxymethyl)tetrahydrofuran (BHMTHF), both promising renewable monomers, was investigated. Three commercial catalysts, Ru/C, Pd/C and Pt/C, were tested in the hydrogenation of aqueous HMF solutions (2?3 wt%), using a metal loading of 1 wt% respect to HMF content. By appropriate tuning of the process conditions, either BHMF or BHMTHF were obtained in good yields, and Ru/C resulted the best catalyst for this purpose, allowing us to obtain BHMF or BHMTHF yields up to 93.0 and 95.3 mol%, respectively. This catalyst was also tested for in the hydrogenation of a crude HMF-rich hydrolyzate, obtained by one-pot the dehydration of fructose. The influence of each component of this hydrolyzate on the hydrogenation efficiency was investigated, including unconverted fructose, rehydration acids and humins, in order to improve the yields towards each furan diol. Moreover, ICP-OES and TEM analysis showed that the catalyst was not subjected to important leaching and sintering phenomena, as further confirmed by catalyst recycling study.

Screening of the Maybridge compound collection identified 4-arylphthalazinones as micromolar inhibitors of PARP-1 catalytic activity. Subsequent optimisation of both inhibitory activity and metabolic stability led to a novel series of meta-substituted 4-benzyl-2H-phthalazin-1-ones with low nanomolar, cellular activity as PARP-1 inhibitors and promising metabolic stability in vitro.

Persulfate is used as an oxidizing breaker in hydraulic fracturing fluids to breakdown gelling agents and clean out wellbores. Persulfate may be activated using conditions like those encountered in the wellbore, producing strong oxidizing radicals that degrade organic compounds. Thus, this study examined persulfate activated transformation of organic additives in a simulated hydraulic fracturing brine by investigating the transformation of furfural. Pseudo-first-order reactions kinetics of furfural degradation in conditions that mimic a fracture, including high temperature, acidified pH, ferric sulfate, and a laboratory simulated hydraulic fracturing brine, were established. The activation energies for furfural removal in acidic (pH 2.54) hydraulic fracturing brine was 105.6 kJ mol?1 without ferric sulfate and 105.1 kJ mol?1 with 23.3 mg L?1 ferric sulfate. A high-pressure reactor was used to simulate the effects of pressure on persulfate activation. Increasing pressure was shown to increase activation of persulfate at 55 C. Applying 3000 psi to the reactor nearly halved the apparent furfural activation energy compared to experiments at atmospheric pressure. Finally, reaction byproducts were presented with the findings showing that halogenated organic byproducts form in hydraulic fracturing brine during persulfate use.

A variety of monosubstituted gamma-lactols 4-6 were prepared in good yields by DIBAL reduction of the corresponding gamma-lactones 1-3.The monophenyl-substituted lactols 4b-6b were transformed into disubstituted tetrahydrofuran derivatives by replacement of the hydroxyl group by the alkyl residue of organometallic compounds used as nucleophiles.The diastereoselectivity of the substitution was found to depend strongly on the substitution pattern of the gamma-lactols.For the reaction of the 3- and 4-substituted derivatives 4b and 5b, respectively, good to excellent trans selectivity was observed, while the 5-substituted derivative reacted without any diastereoselectivity.These results were interpreted by means of the Felkin-Anh model. – Keywords: gamma-Lactone / Reduction / gamma-Lactol / Lewis acid / Tetrahydrofurans

Chemistry is traditionally divided into organic and inorganic chemistry. name: Gamma-heptalactone, The former is the study of compounds containing at least one carbon-hydrogen bonds.In a patent，Which mentioned a new discovery about 105-21-5

Non-polar oils are commonly used as collectors for coal flotation but they are generally lack of collecting efficiency to low rank coals even at a high dosage. In this study, dodecane, a representative of the non-polar oily collectors, was treated by dielectric barrier discharge (DBD) air plasma and the product was employed in the flotation of a low-rank coal slime, attempting to improve its flotation performance. Results show that the dodecane treated by DBD air plasma led to a high concentrate yield and combustible material recovery. The mechanism underpinning the observed effect was investigated using gas chromatograph-mass spectrometer (GC?MS), Fourier transform infrared spectroscopy (FTIR) and contact angle measurements. The effect of UC (untreated collector) and TC (treated collector) on coal and gangue were detected, respectively. It was found that abundant polar substances were produced after the air plasma treatment. The functional groups including O[sbnd]C[dbnd]O and [sbnd]OH enhanced the adsorption of collectors onto the oxygenated surface sites of the coal and gangue, and thus increased the hydrophobicity of coal and gangue. According to the contact measurements, the increase of coal in hydrophobicity is stronger than that in gangue, as evidenced by their measured contact angle of organic matter increasing from 78.23 to 95.82, and gangue increasing from 75.11 to 83.22 after conditioning with the TC. This implies that oily collectors after air plasma treatment is effective to improve low rank coal flotation performance, which may have great potential for industrial applications.

4971-56-6, Name is Furan-2,4(3H,5H)-dione, belongs to tetrahydrofurans compound, is a common compound. Recommanded Product: Furan-2,4(3H,5H)-dioneIn an article, once mentioned the new application about 4971-56-6.

The present invention relates to an isoxazole derivative, the compound of formula (I) herein after referred to as GIT27-NO, which is the NO-donating structurally modified form of (S,R)-3-phenyl-4,5-dihydro-5-isoxasole acetic acid, herein after referred to as VGX-1027. Treatment of three tumor cell lines, rat astrocytoma C6, mouse fibrosarcoma L929, and mouse melanoma B16 cells with GIT27-NO resulted in a significant reduction of cell respiration and of number of viable cells, while VGX-1027 was completely ineffective. Hemoglobin, which act as NO-scavenger, restored cell viability, thus indicating the NO-mediated tumoricidal effect of compound (I). GIT27-NO triggered apoptotic cell death in L929 cell cultures, while autophagic cell death is mainly responsible for the diminished viability of C6 and B16 cells. Moreover, GIT27-NO induced the production of reactive oxygen species which can be neutralized by antioxidant N-acetyl cysteine (NAC), indicating that reactive oxygen species (ROS) are at least partly involved in the reduction of cell viability. The anti-tumor activity of GIT27-NO is mediated through activation of MAP kinases (ERK1/2, p38 and JNK) in cell-specific manner. The role of MAP kinases was further confirmed by specific inhibitors of these molecules, PD98059, SB202190, and SP600125. Finally, in vivo treatment with GIT27-NO significantly reduced tumor growth in syngeneic C57BL/6 mice implanted with B16 melanoma.
