Guo, Yi-lin published the artcileStudy on the characteristic of β-O-4 lignin polymer model compound fast pyrolysis catalyzed by K⁺, Ca²⁺, Fe²⁺, HPLC of Formula: 645-56-7, the publication is Gongcheng Rewuli Xuebao (2021), 42(12), 3073-3082, database is CAplus.

In order to reveal the mechanism of the influence of C_α functional groups and metal ions on the pyrolysis process of lignin, this study synthesized two β-O-4 type lignin polymer model compounds (Ca connected to carbonyl and hydroxyl functional groups resp.), and carried out Py-GC-MS fast pyrolysis experiment catalyzed by acetate at different temperatures (500°C, 650°C, 800°C) and different metal ions(K⁺, Ca²⁺, Fe²⁺). The exptl. results show that the C_β-O bond is easier to break than the C_α-C_β bond. The homolytic reaction produces more phenolic compounds; the addition of K⁺, Ca²⁺, Fe²⁺ metal ions can reduce the temperature required during pyrolysis, promote the generation of phenolic products, inhibited the formation of anisyl (aldehyde) and acetophenyl products.

Liu, Gang published the artcileStructure-activity relationship studies on Bax activator SMBA1 for the treatment of ER-positive and triple-negative breast cancer, Safety of 2-Morpholinoethanol, the publication is European Journal of Medicinal Chemistry (2019), 589-605, database is CAplus and MEDLINE.

In an effort to develop novel Bax activators for breast cancer treatment, a series of diverse analogs have been designed and synthesized based on lead compound SMBA1 through several strategies, including introducing various alkylamino side chains to have a deeper access to S184 pocket, replacing carbon atoms with nitrogen, and reducing the nitro group of 9H-fluorene scaffold. Compounds 14 (CYD-2-11, I) and 49 (CYD-4-61, II) have been identified to exhibit significantly improved antiproliferative activity compared to SMBA1, with IC₅₀ values of 3.22 μM and 0.07 μM against triple-neg. breast cancer MDA-MB-231 and 3.81 μM and 0.06 μM against ER-pos. breast cancer MCF-7 cell lines, resp. Mechanism of action studies of II indicated that it can activate Bax protein to induce cytochrome c release and regulate apoptotic biomarkers, leading to cancer cell apoptosis. Further in vivo efficacy studies of I and II in nude mice bearing MDA-MB-231 tumor xenografts demonstrated that these drug candidates can significantly suppress tumor growth, indicating their therapeutic potential for the treatment of breast cancer.

Jana, Sripati published the artcilePhotoinduced Proton-Transfer Reactions for Mild O-H Functionalization of Unreactive Alcohols, Product Details of C3H5F3O, the publication is Angewandte Chemie, International Edition (2020), 59(14), 5562-5566, database is CAplus and MEDLINE.

Hexafluoroisopropanol is typically considered as an unreactive solvent and not as a reagent in organic synthesis. Herein, we report on a mild and efficient photochem. reaction of aryl diazoacetates with hexafluoroisopropanol that enables, under stoichiometric reaction conditions, the synthesis of fluorinated ethers in excellent yield. Mechanistic studies indicate there is a preorganization of hexafluoroisopropanol and the diazoalkane acts as an unreactive hydrogen-bonding complex. Only after photoexcitation does this complex undergo a protonation-substitution reaction to the reaction product. Investigations on the applicability of this photochem. transformation show that a broad variety of acidic alcs. can be subjected to this transformation and thus demonstrate the feasibility of this concept for O-H functionalization reactions (54 examples, up to 98% yield).

Li, Yitao published the artcileDesign, synthesis, and biological evaluation of phenyloxadiazole derivatives as potential antifungal agents against phytopathogenic fungi, Recommanded Product: 4-Propylphenol, the publication is Monatshefte fuer Chemie (2021), 152(1), 121-135, database is CAplus.

A novel series of picarbutrazox-inspired oxadiazole hybrids I (R = 4-cyanophenyl, 3,5-dibromophenyl, 3,5-dichloro-4-(3-methoxyphenoxy)phenyl, etc.) was synthesized and the derivatives’ biol. activity against phytopathogenic fungi was investigated. The mols. were designed by retaining the active fragment of tetrazolyl phenyloxime ether of lead compound picarbutrazox, while introducing the potentially active oxadiazole-derived fragment I. Bioassay results revealed that some of the title compounds showed potent in vivo antifungal activities to control cucumber downy mildew. Therefore, this novel oxadiazole phenyloxadiazole derivative I can be used as a potential antifungal agent to control cucumber downy mildew and other phytopathogenic fungi for crop protection.

Ambreen, Samina published the artcileNovel degradation pathways for Chlorpyrifos and 3, 5, 6-Trichloro-2-pyridinol degradation by bacterial strain Bacillus thuringiensis MB497 isolated from agricultural fields of Mianwali, Pakistan, Name: 4-Propylphenol, the publication is Pesticide Biochemistry and Physiology (2021), 104750, database is CAplus and MEDLINE.

Over use of organophosphate pesticides including Chlorpyrifos (CPF) has led to contamination of soil and water resources, resulting in serious health problems in humans along with other non-target organisms. The current study was aimed to investigate Chlorpyrifos as well as 3, 5, 6-Trichloro-2-pyridinol (TCP) biodegradation tendency of bacterial strain Bacillus thuringiensis MB497 isolated from wheat/cotton fields of Dera Saleemabad, Mianwali, Pakistan, having a history of heavy Organophosphate pesticides application. HPLC anal. revealed almost 99% degradation of the spiked CPF (200 mg L^-1) in M-9 broth, soil slurry and soil microcosm by MB497 after 9 days of incubation. Strain MB497 was also able to degrade and transform TCP (28 mg L^-1), up to 90.57% after 72 h of incubation in M-9 broth. A novel compound Di-iso-Pr methanephosphonate along with known products of 3, 5, 6-Trichloro-2-pyridinol (TCP), Di-Et thiophospsphate and Phosphorothioic acid were detected as metabolites of CPF by GCMS anal. Three novel metabolites of TCP (p-Pr phenol, 2-Ethoxy-4, 4, 5, 5-tetramethyloxazoline and 3-(2, 4, 5-Trichlorophenoxy)-1-propyne) were identified after 72 h. Based on these metabolites, new/amended metabolic pathways for CPF and TCP degradation in these bacteria has been suggested.

Ferraris, John P. published the artcileGrafting of buckminsterfullerene onto polythiophene: novel intramolecular donor-acceptor polymers, Application of Thiophen-3-ol, the publication is Optical Materials (Amsterdam) (1998), 9(1-4), 34-42, database is CAplus.

Conjugated polymer-fullerene composites have shown efficient photoinduced charge transfer. The attachment of a fullerene moiety to the conducting polymer backbone is expected to lead to materials with more intimate association of the donor/acceptor sites. Two approaches to the attachment of fullerenes onto polythiophene derivatives were explored. In the first case, C₆₀ fullerene was bonded to a bithiophene derivative which can be electropolymerized In the second, solvent-processable polythiophene copolymers were prepared and functionalized with fullerene. Both these systems exhibit electrochem. and optoelectrochem. properties for fullerene and the conducting polymer, as seen in cyclic voltammograms and UV-visible spectra.

Morino, Yusuke published the artcileCu/N-Oxyl-catalyzed aerobic oxidative esterification to oxalic acid diesters from ethylene glycol via highly selective intermolecular alcohol oxidation, Name: 3,3,3-Trifluoropropan-1-ol, the publication is Green Chemistry (2022), 24(5), 2017-2026, database is CAplus.

One of the ideal green esterification reactions is aerobic oxidative esterification using only a stoichiometric amount of different alcs. via intermol. selective alc. oxidation followed by hemiacetal formation by the addition of the other alc. and hemiacetal oxidation to esters. However, oxalic acid diester synthesis via oxidative esterification has not been reported to date, possibly owing to the difficulty of selectivity control of intermol. alc. oxidation and the chelating effects of ethylene glycol-derived alcs./hemiacetals on inhibiting oxidation catalysts. Herein, using a CuCl/tetramethylethylenediamine/1,5-dimethyl-9-azanoradamantane N-oxyl catalyst, authors describe a highly efficient aerobic oxidative esterification reaction of ethylene glycol to various oxalic acid diesters via selective oxidation of ethylene glycol-derived alcs./hemiacetals even in the presence of other aliphatic primary alcs. Notably, the green reaction works well using an ideal stoichiometric ratio of ethylene glycol and primary/secondary alcs. Thorough exptl. investigation and theor. calculations revealed that highly selective oxidative esterification is enabled by the preferential bidentate coordination of ethylene glycol-derived alcs./hemiacetals to the Cu(II) species, followed by efficient two-electron/one-proton transfer.

Wang, Yu-Huang published the artcileReductive hydroxyalkylation/alkylation of amines with lactones/esters, COA of Formula: C8H19NO, the publication is Organic & Biomolecular Chemistry (2012), 10(32), 6504-6511, database is CAplus and MEDLINE.

We have developed a one-pot method for the direct intermol. reductive hydroxyalkylation or alkylation of amines using lactones or esters as the hydroxyalkylating/alkylating reagents. The method is based on the in situ amidation of lactones/esters with DIBAL-H-amine complex (for primary amines) or DIBAL-H-amine hydrochloride salt complex (for secondary amines), followed by reduction of the amides with an excess of DIBAL-H. Different from the reduction of Weinreb amides with DIBAL-H where aldehydes are formed, the reduction of the in situ formed Weinreb amides yielded amines. Moreover, this method is not limited to Weinreb amides, instead, it also works for other amides in general. A plausible mechanism is suggested to account for the outcome of the reactions.

Kuang, Yuting published the artcileInduction of Genes Implicated in Stress Response and Autophagy by a Novel Quinolin-8-yl-nicotinamide QN523 in Pancreatic Cancer, Computed Properties of 622-40-2, the publication is Journal of Medicinal Chemistry (2022), 65(8), 6133-6156, database is CAplus and MEDLINE.

Using a cytotoxicity-based phenotypic screen of a highly diverse library of 20,000 small-mol. compounds, we identified a quinolin-8-yl-nicotinamide, QN519, as a promising lead. QN519 represents a novel scaffold with drug-like properties, showing potent in vitro cytotoxicity in a panel of 12 cancer cell lines. Subsequently, lead optimization campaign generated compounds with IC₅₀ values < 1μM. An optimized compound, QN523, shows significant in vivo efficacy in a pancreatic cancer xenograft model. QN523 treatment significantly increased the expression of HSPA5, DDIT3, TRIB3, and ATF3 genes, suggesting activation of the stress response pathway. We also observed a significant increase in the expression of WIPI1, HERPUD1, GABARAPL1, and MAP1LC3B, implicating autophagy as a major mechanism of action. Due to the lack of effective treatments for pancreatic cancer, discovery of novel agents such as the QN series of compounds with unique mechanism of action has the potential to fulfill a clear unmet medical need.

Zhang, Kaifu published the artcileSynthesis of a Gold-Metal Oxide Core-Satellite Nanostructure for In Situ SERS Study of CuO-Catalyzed Photooxidation, Application of Triethylsilanol, the publication is Angewandte Chemie, International Edition (2020), 59(41), 18003-18009, database is CAplus and MEDLINE.

This work reports on an assembling-calcining method for preparing gold-metal oxide core-satellite nanostructures, which enable surface-enhanced Raman spectroscopic detection of chem. reactions on metal oxide nanoparticles. By using the nanostructure, we study the photooxidation of Si-H catalyzed by CuO nanoparticles. As evidenced by the in situ spectroscopic results, oxygen vacancies of CuO are found to be very active sites for oxygen activation, and hydroxyl radicals (·OH) adsorbed at the catalytic sites are likely to be the reactive intermediates that trigger the conversion from silanes into the corresponding silanols. According to our finding, oxygen vacancy-rich CuO catalysts are confirmed to be of both high activity and selectivity in photooxidation of various silanes.
