Meng, Xiangzhan published the artcileSelective Oxidation of Amino Alcohols to Amino Acids over Au Supported on Monoclinic ZrO₂: Dominant Active Sites and Kinetic Study, Safety of 2-Aminobutan-1-ol, the publication is Industrial & Engineering Chemistry Research (2019), 58(19), 8506-8516, database is CAplus.

Au supported on monoclinic ZrO₂ (Au/m-ZrO₂) prepared by deposition-precipitation method showed excellent catalytic performance in the aerobic oxidation of amino alcs. to amino acids, i.e., glycine, alanine, serine, β-alanine, and 2-aminobutyric acid. The Au particle size and valence distribution of the gold species were adjusted by calcination temperature, as demonstrated by XRD, TEM, UV-vis DRS, XPS, and H₂-TPR, which significantly influenced the catalytic activity but not the selectivity of amino acids. Metallic gold atoms on the surface were shown to be the active sites by the correlation between reaction rate per mol of metallic Au and Au particle size. The kinetics of oxidation of monoethanolamine (MEA) was studied in detail, and the results indicated that MEA oxidation is a first-order reaction with an activation energy of 52.8 kJ·mol^-1.

Zhu, Zuoyi published the artcileStructural characterisation and antioxidant activity of melanoidins from high-temperature fermented apple, HPLC of Formula: 96-20-8, the publication is International Journal of Food Science and Technology (2021), 56(5), 2471-2480, database is CAplus.

Summary : High-temperature fermented apple is a new fermented product with characteristic black appearance, which is prepared through natural fermentation of whole fresh apple at controlled high temperature (60-90°C) and humidity (relative humidity of 50-90%). In this work, melanoidins from high-temperature fermented apple were obtained by ultrafiltration and subsequent diafiltration. The structural characterization of melanoidins was investigated in the present study. Results showed that the mol. weight of the obtained melanoidins was about 179 kDa and the melanoidins were comprised primarily of furans by pyrolysis-gas chromatog.-mass spectrometry. Antioxidant activities of the high-temperature fermented apple and its melanoidins were evaluated by ABTS, DPPH, hydroxyl radicals, ferric reducing antioxidant power and Fe2+-chelating assays. Both high-temperature fermented apple and its melanoidins showed extremely high antioxidant activities in scavenging hydroxyl radicals. High correlation between the antioxidant activity assayed methods and the physicochem. characteristics of melanoidins was obtained. The contribution of melanoidins to the total antioxidant capacity of high-temperature fermented apple was determined

Zak, Mark published the artcileMinimizing CYP2C9 Inhibition of Exposed-Pyridine NAMPT (Nicotinamide Phosphoribosyltransferase) Inhibitors, COA of Formula: C5H10O, the publication is Journal of Medicinal Chemistry (2016), 59(18), 8345-8368, database is CAplus and MEDLINE.

NAMPT inhibitors may show potential as therapeutics for oncol. Throughout our NAMPT inhibitor program, we found that exposed pyridines or related heterocyclic systems in the left-hand portion of the inhibitors are necessary pharmacophores for potent cellular NAMPT inhibition. However, when combined with a benzyl group in the center of the inhibitors, such pyridine-like moieties also led to consistent and potent inhibition of CYP2C9. In an attempt to reduce CYP2C9 inhibition, a parallel synthesis approach was used to identify central benzyl group replacements with increased Fsp3. A spirocyclic central motif was thus discovered that was combined with left-hand pyridines (or pyridine-like systems) to provide cellularly potent NAMPT inhibitors with minimal CYP2C9 inhibition. Further optimization of potency and ADME properties led to the discovery of compound 68, a highly potent NAMPT inhibitor with outstanding efficacy in a mouse tumor xenograft model and lacking measurable CYP2C9 inhibition at the concentrations tested.

Voller, Jiri published the artcile6-Substituted purines as ROCK inhibitors with anti-metastatic activity, Application In Synthesis of 96-20-8, the publication is Bioorganic Chemistry (2019), 103005, database is CAplus and MEDLINE.

Rho-associated serine/threonine kinases (ROCKs) are principal regulators of the actin cytoskeleton that regulate the contractility, shape, motility, and invasion of cells. We explored the relationships between structure and anti-ROCK2 activity in a group of purine derivatives substituted at the C6 atom by piperidin-1-yl or azepan-1-yl groups. Structure-activity relationship (SAR) analyses suggested that anti-ROCK activity is retained, and may be further increased, by substitution of the parent compounds at the C2 atom or by expansion of the C6 side chain. These inhibitors of ROCK can reach effective concentrations within cells, as demonstrated by a decrease in phosphorylation of the ROCK target MLC, and by inhibition of the ROCK-dependent invasion of melanoma cells in the collagen matrix. Our study may be useful for further optimization of C6-substituted purine inhibitors of ROCKs and of other sensitive kinases identified by the screening of a broad panel of protein kinases.

Nageswara Rao, Desaboini published the artcileDiscovery of Quinoxaline-Based P1-P3 Macrocyclic NS3/4A Protease Inhibitors with Potent Activity against Drug-Resistant Hepatitis C Virus Variants, Recommanded Product: 1-Methylcyclobutan-1-ol, the publication is Journal of Medicinal Chemistry (2021), 64(16), 11972-11989, database is CAplus and MEDLINE.

The three pan-genotypic HCV NS3/4A protease inhibitors (PIs) currently in clin. use-grazoprevir, glecaprevir, and voxilaprevir-are quinoxaline-based P2-P4 macrocycles and thus exhibit similar resistance profiles. Using our quinoxaline-based P1-P3 macrocyclic lead compounds as an alternative chem. scaffold, we explored structure-activity relationships (SARs) at the P2 and P4 positions to develop pan-genotypic PIs that avoid drug resistance. A structure-guided strategy was used to design and synthesize two series of compounds with different P2 quinoxalines in combination with diverse P4 groups of varying sizes and shapes, with and without fluorine substitutions. Our SAR data and cocrystal structures revealed the interplay between the P2 and P4 groups, which influenced inhibitor binding and the overall resistance profile. Optimizing inhibitor interactions in the S4 pocket led to PIs with excellent antiviral activity against clin. relevant PI-resistant HCV variants and genotype 3, providing potential pan-genotypic inhibitors with improved resistance profiles.

A Ni-catalyzed reductive deaminative arylation at unactivated sp³ carbon centers is described. This operationally simple and user-friendly protocol exhibits excellent chemoselectivity profile and broad substrate scope, thus complementing existing metal-catalyzed cross-coupling reactions to forge sp³ C-C linkages. These virtues have been assessed in the context of late-stage functionalization, hence providing a strategic advantage to reliably generate structure diversity with amine-containing drugs.

Hayri-Senel, Tugba published the artcileThe use of poly(styrene-co-chloromethyl styrene) in the modification of triglyceride oils, HPLC of Formula: 96-20-8, the publication is Journal of Coatings Technology and Research, database is CAplus.

In this study, Poly(styrene-co-chloromethyl styrene) [Poly(St-co-CMS)] was prepared and used in the modification of triglyceride oils. The obtained modified triglyceride product was examined in view of oil-based binder. Nitroxide-mediated radical polymerization (NMRP) technique was applied for Poly(St-co-CMS) synthesis. Chloro groups on the Poly(St-co-CMS) backbone were reacted with 2-amino-1-butanol (2-AB) in order to obtain a polymer with hydroxyl ended side branches, [Poly(St-OH)], which were further combined with partial glycerides (PGs) through the reaction with toluene diisocyanate (TDI). The resulting product can also be considered as a polystyrene-modified urethane oil [Poly(St-OH)-SUO]. The structures of both intermediates, [Poly(St-co-CMS), Poly(St-OH)], and final products [Poly(St-OH)-SUO] were verified by using FTIR and ¹H-NMR analyses. Addnl., thermal properties of the samples were determined The film properties of Poly(St-OH)-SUO samples prepared with different polymer/oil ratios and classic urethane oil were examined Poly(St-OH)-SUO-40 sample exhibited the best film properties among the others. In the end, the obtained results showed that Poly(St-OH)-SUO-40 could be utilized as an oil-based binder.

Yang, N. C. published the artcilePhotochemical reactions of ketones in solution, Formula: C5H10O, the publication is Journal of the American Chemical Society (1958), 2913-14, database is CAplus.

The light-induced reactions of simple aliphatic ketones in saturated hydrocarbons were studied. Ketones with no γ-H atom gave the corresponding alc. and the addition product with the hydrocarbon. Ketones with γ-H atoms gave Me₂CO, an olefin, and a cyclobutanol derivative These reactions differ markedly from those previously observed in the gas phase. The formation of cyclobutanols offers a route to a group of compounds otherwise difficult to prepare A 1:8 mixture of Me₂CO and cyclohexane (I) irradiated in quartz yielded a small amount of CH₄ and CO. Fractional distillation and gas chromatography yielded Me₂CHOH 53, pinacol 15, MeCOCH₂COMe 8, and cyclohexyldimethylcarbinol 12%; cyclohexylcyclohexene and hydrocarbon polymers were also obtained. The recovered I showed slight unsaturation Similarly, irradiation of 2-pentanone in I gave Me₂CO, C₂H₄, and 1-methylcyclobutanol (phenylurethan m.p. 141°). Irradiation of 2-octanone in isoöctane gave equimol. amounts of Me₂CO and CH₂:CHPr (67%), and 17% 1-methyl-2-propylcyclobutanol b₉ 67-8°, n_D²⁰ 1.4420, phenylurethan m. 78deg;. Irradiation of 2-nonanone in isoöctane yielded Me₂CO, 1-hexene, and 1-methyl-2-butylcyclobutanol, b_0.8 49-50°, n_D²⁰ 1.4441, phenylurethan m.p. 91°. An intramol, mechanism is formulated for the formation of cyclobutanols.
