Tetrahedron: Asymmetry published new progress about Enzymic transglycosylation. 2595-07-5 belongs to class alcohols-buliding-blocks, name is (2R,3R,4S,5R,6R)-2-(Allyloxy)-6-(hydroxymethyl)tetrahydro-2H-pyran-3,4,5-triol, and the molecular formula is C9H16O6, HPLC of Formula: 2595-07-5.

Chiffoleauu-Giraud, V. published the artcileβ-Galactosidase transferase activity in ice and use of vinyl-β-D-galactoside as donor, HPLC of Formula: 2595-07-5, the main research area is oligosaccharide disaccharide preparation enzymic; vinylgalactoside transglycosidation glycoside galactosidase catalyst.

The ability of vinyl-β-D-galactoside as a donor in transglycosylation reactions catalyzed by the β-glycosidase from Aspergillus oryzae using allylic alc. and methyl-α-galactoside as acceptors is tested. A kinetic study made in comparison with another donor, the 2-nitrophenyl-β-D-galactoside, shows that the use of the latter leads at room temperature to better yields than those obtained form the former. A reverse situation is observed in ice at -7°C, conditions in which the yield for transglycosylation can be enhanced from 59% to 82% with methyl-α-galactoside as an acceptor.

Wang, Delong’s team published research in Pest Management Science in 2022-11-30 | CAS: 124-76-5

Pest Management Science published new progress about Color. 124-76-5 belongs to class alcohols-buliding-blocks, name is rel-(1R,2R,4R)-1,7,7-Trimethylbicyclo[2.2.1]heptan-2-ol, and the molecular formula is C10H18O, Application In Synthesis of 124-76-5.

Wang, Delong published the artcileGuaiacol as a natural melanin biosynthesis inhibitor to control northern corn leaf blight, Application In Synthesis of 124-76-5, the main research area is guaiacol natural melanin essential oil corn leaf blight; DHN melanin biosynthesis inhibitor; guaiacol; northern corn leaf blight; plant essential oil compounds.

BACKGROUND : The natural 1,8-dihydroxynaphthalene (DHN) melanin biosynthesis inhibitors (MBIs) are one of the promising approaches to the integrated management of plant diseases but have received scarce attention until now. Herein, to explore the natural DHN MBIs used in the control of northern corn leaf blight (NCLB), a library of 53 essential oil compounds was used to screen the MBIs against Exserohilum turcicum, the causal pathogen of NCLB, using tricyclazole as a reference compound RESULTS : The results of morphol. change in the colony, thermogravimetric anal., UV-visible spectroscopy, and transmission electron microscopy confirmed that guaiacol could effectively inhibit the melanin production at 50 μg/mL under in vitro conditions. The in vitro bioassay results indicated that this inhibition effect was concentration-dependent and the min. inhibition concentration of guaiacol was 50 μg/mL. The in vivo exptl. results demonstrated that guaiacol significantly inhibited appressorium formation and penetration on corn leaf sheaths at the concentration of 500 μg/mL. The pot experiment results revealed that there were no differences between guaiacol (500 μg/mL) and tricyclazole (100 μg/mL) in control efficacy. The enzymic assay suggested that guaiacol might exert the activity through inhibiting DHN polymerization to form melanins, which was distinct from tricyclazole. CONCLUSIONS : Taken together, this study screened out guaiacol as a natural MBI from 53 essential oil compounds and verified its effectiveness in the control of NCLB at 500 μg/mL. Above all, this research opened an avenue for exploring natural DHN MBIs in the integrated management of plant diseases. 2022 Society of Chem. Industry.

Li, Ning’s team published research in Frontiers in Genetics in 2021 | CAS: 97-67-6

Frontiers in Genetics published new progress about Animal gene Role: BSU (Biological Study, Unclassified), BIOL (Biological Study) (AAM). 97-67-6 belongs to class alcohols-buliding-blocks, name is (S)-2-hydroxysuccinic acid, and the molecular formula is C4H6O5, COA of Formula: C4H6O5.

Li, Ning published the artcileIdentification of the carbohydrate and organic acid metabolism genes responsible for Brix in tomato fruit by transcriptome and metabolome analysis, COA of Formula: C4H6O5, the main research area is carbohydrate organic acid metabolism Brix tomato fruit transcriptome metabolome; TCA cycle; carbohydrate; fruit brix; metabolic; organic acid; tomato; transcriptome.

Sugar and organic acids not only contribute to the formation of soluble solids (Brix) but also are an essential factor affecting the overall flavor intensity. However, the possible metabolic targets and mol. synthesis mechanisms remain to be further clarified. UHPLC-HRMS (ultrahigh-performance liquid chromatog. and high-resolution mass spectrometry) combined with comparative transcriptome anal. were performed in fruits at green ripe (S1), turning-color (S2), and red ripe (S3) stages of two tomato genotypes TM-1 (Solanum galapagense L., LA0436) and TM-38 (S. lycopersicum L. cultivar M82, LA3475) that vary in fruit Brix. The fruit Brix of TM-1 was nearly twice that of TM-38 at S3. Nevertheless, TM-1 accumulated 1.84- and 2.77-fold the L-malic acid and citric acid in red ripe fruit (S3) compared with TM-38, resp. D-glucose and D-fructose in TM-1 and TM-38 fruits tended to be similar at S3. Concomitantly, the sugar/organic acid ratio of TM-38 fruits were 23. 08-, 4. 38-, and 2.59-fold higher than that of TM-1 fruits at S1, S2, and S3, resp. Among starch and sucrose (carbohydrate, CHO) metabolism (ko00500) genes, SUS (Solyc07g042550.3) and BAM (Solyc08g077530.3) were pos. (r = 0.885-0.931) correlated with the sugar/organic acid ratio. Besides, INV (Solyc09g010080.3 and Solyc09g010090.5.1), AAM (Solyc04g082090.3), 4-α-GTase (Solyc02g020980.2.1), BGL2 (Solyc06g073750.4, Solyc06g073760.3, and Solyc01g081170.3), TPS (Solyc01g005210.2 and Solyc07g006500.3), and TPP (Solyc08g079060.4) were neg. (r = -0.823 to -0.918) correlated with the sugar/organic acid ratio. The organic acid (TCA cycle) metabolism (ko00020) gene ALMT (Solyc01g096140.3) was also neg. (r = -0.905) correlated with the sugar/organic acid ratio. Citric acid may play a more dominant role in the sugar/organic acid ratio of the tomato fruit, and the contribution of both L-malic acid and citric acid to the fruit Brix was much greater than that of D-glucose and D-fructose. Genes involved in CHO and TCA metabolism, which have a significant correlation with the sugar/organic acid ratio were considered to be the contributing factors of fruit Brix.

Behrman, E. J. et al. published their research in Organic Reactions (Hoboken, NJ, United States) in 1988 | CAS: 52010-89-6

2,5-Dihydroxy-4-methylbenzaldehyde (cas: 52010-89-6) belongs to alcohols. The oxygen atom of the strongly polarized O―H bond of an alcohol pulls electron density away from the hydrogen atom. This polarized hydrogen, which bears a partial positive charge, can form a hydrogen bond with a pair of nonbonding electrons on another oxygen atom. Grignard and organolithium reagents are powerful tools for organic synthesis, and the most common products of their reactions are alcohols.Synthetic Route of C8H8O3

Ahmed, Sarfraz et al. published their research in Soil Biology in 2017 | CAS: 65-22-5

3-Hydroxy-5-(hydroxymethyl)-2-methylisonicotinaldehyde hydrochloride (cas: 65-22-5) belongs to alcohols. A strong base can deprotonate an alcohol to yield an alkoxide ion (R―O−). For example, sodamide (NaNH2), a very strong base, abstracts the hydrogen atom of an alcohol. A multistep synthesis may use Grignard-like reactions to form an alcohol with the desired carbon structure, followed by reactions to convert the hydroxyl group of the alcohol to the desired functionality.Recommanded Product: 65-22-5

Nagae, Norikazu et al. published their research in Bunseki in 2021 | CAS: 65-22-5

3-Hydroxy-5-(hydroxymethyl)-2-methylisonicotinaldehyde hydrochloride (cas: 65-22-5) belongs to alcohols. Because alcohols are easily synthesized and easily transformed into other compounds, they serve as important intermediates in organic synthesis. Converting an alcohol to an alkene requires removal of the hydroxyl group and a hydrogen atom on the neighbouring carbon atom. Dehydrations are most commonly carried out by warming the alcohol in the presence of a strong dehydrating acid, such as concentrated sulfuric acid.Application of 65-22-5
