Wang, Shan published the artcileDesign, synthesis, and biological evaluation of 2,4-diamino pyrimidine derivatives as potent FAK inhibitors with anti-cancer and anti-angiogenesis activities, Category: ethers-buliding-blocks, the publication is European Journal of Medicinal Chemistry (2021), 113573, database is CAplus and MEDLINE.

A series of 2,4-diamino pyrimidine (DAPY) derivatives I (R¹ = 2-ClC₆H₄, 4-MeOC₆H₄, 4-BrC₆H₄, etc.), II (R² = 4-H₂NC₆H₄, 4-MeOC₆H₄, 2-O₂NC₆H₄, etc.) were designed, synthesized, and evaluated as inhibitors of focal adhesion kinase (FAK) with antitumor and anti-angiogenesis activities. Most compounds effectively suppressed the enzymic activities of FAK, and the IC₅₀s of I (R¹ = 2-ClC₆H₄) and II (R² = 2-MeOC₆H₄) were 2.75 and 1.87 nM, resp. They exhibited strong antiproliferative effects against seven human cancer cells, with IC₅₀ values against two FAK-overexpressing pancreatic cancer cells (PANC-1 and BxPC-3) of 0.98μM, 0.55μM, and 0.11μM, 0.15μM, resp. Moreover, the above two compounds obviously suppressed the colony formation, migration, and invasion of PANC-1 cells in a dose-dependent manner. Meanwhile, these two compounds could induce the apoptosis of PANC-1 cells and arrest the cell cycle in G2/M phase according to the flow cytometry assay. Western blot revealed that these compounds effectively inhibited the FAK/PI3K/Akt signal pathway and significantly decreased the expression of cyclin D1 and Bcl-2. In addition, the above compounds potently inhibited the antiproliferative of HUVECs and obviously altered the cell morphol and also significantly inhibited the migration, tube formation of HUVECs and severely impaired the angiogenesis in the zebrafish model. Overall, these results revealed the potential of these compounds as promising candidates for further preclin. studies.

He, Ben published the artcileortho-Terphenylene Viologens with Through-Space Conjugation for Enhanced Photocatalytic Oxidative Coupling and Hydrogen Evolution, Application In Synthesis of 6850-57-3, the publication is Journal of the American Chemical Society (2022), 144(10), 4422-4430, database is CAplus and MEDLINE.

A series of novel ortho-terphenylene viologen derivatives (o-TPV²⁺) with through-space conjugation (TSC) via the combination of ortho-terphenylene skeletons with viologen structure is reported. Their optoelectronic properties can be adjusted by N-arylation or N-alkylation reactions. Compared with other viologen derivatives, o-TPV²⁺ not only exhibits strong photoluminescence, but also retards the charge recombination process and stabilizes diradicals state without forming a quinoid structure due to the special TSC effect. Based on their special redox characteristics, o-TPV²⁺ were applied to the photocatalytic oxidative coupling of benzylamine with 96% yield. In addition, pTA-o-TPV²⁺ (tethered with p-toluic acid) modified g-C₃N₄ was used for visible-light-driven hydrogen production for the first time, exceeding 15 times the rate over unmodified g-C₃N₄.

Mi, Si published the artcileGeographical discrimination and authentication of Chinese garlic based on multi-element, volatile and metabolomics profiling combined with chemometrics, Application In Synthesis of 91-16-7, the publication is Food Control (2021), 108328, database is CAplus.

This study aims to discriminate the garlics collected from four different geog. locations of China. The multi-element (12 samples), volatile (12 samples) and metabolome (24 samples) composition of the garlics were analyzed and compared. A total of 34 chem. elements, 68 volatiles and 854 metabolites were detected in the garlic samples. Significant differences were observed in the chem. element, volatile and metabolomics profiles of the four groups of garlic. Multivariate statistics indicate that 10 chem. elements, 6 volatiles and 225 metabolites could be used as candidate markers for the separation of garlics obtained from Langfang, Jining, Kaifeng and Dali of China. The current work provides a chem. fingerprint of the selected Chinese garlics. Our results demonstrate that chem. profiling in combination with chemometrics has the potential to be used as feasible approaches for the authentication of the geog. origin of garlic.

You, Hongyun published the artcileHydrogenation of Lignin-derived Phenolic Compounds over Ru/C Enhanced by Al₂O₃ Catalyst at Room Temperature, Recommanded Product: 1,2-Dimethoxybenzene, the publication is ChemistrySelect (2022), 7(19), e202200709, database is CAplus.

In this study, an efficient hydrogenation of phenols using Ru/C enhanced Al₂O₃ as catalyst at room temp to obtain cyclohexanols R-OH [R = 2-MeC₆H₁₁, 3-MeC₆H₁₁, 2-MeOC₆H₁₁, etc.] with selectivity close to 100% was reported. The addition of Al₂O₃ could made a significant difference on the phenol adsorption by the introduction of abundant Lewis acid site, which enabled activate aromatic rings by changing the electrophilic substitution reaction of aromatic groups and triggered the occurrence of phenol hydrogenation under the catalysis of Ru/C. The Lewis acid site and metal site cooperated with each other and promoted the conversion of phenols to cyclohexanols as the final products. Moreover, a variety of other phenolic or aromatic compounds were also tested. The steric effects derived from the different substituted groups on aromatic rings had a significant influence on the hydrogenation performances.

Ran, Jiansu published the artcileSignificant Promotion of Carboxyl Groups in Palladium Nanoparticles-Supported Biomass Carbon Catalysts for Efficient Low-Temperature Hydrodeoxygenation of Lignin Derivatives in Water, Related Products of ethers-buliding-blocks, the publication is ACS Sustainable Chemistry & Engineering (2022), 10(22), 7277-7287, database is CAplus.

Selective and efficient low-temperature hydrodeoxygenation (HDO) of lignin derivatives in water for the production of valuable biofuel and chems. is still challenging. Herein, we reported biomass carbon-supported ultrafine Pd nanoparticles as highly active and stable catalysts for low-temperature HDO of vanillin (a typical lignin-derived compound) to 2-methoxy-4-methylphenol (MMP). We found that the abundant carboxyl groups on the resultant catalyst greatly accelerated the conversion of the generated intermediate (vanillyl alc., VAL), and then, the synergistic catalysis between carboxyl groups and Pd nanoparticles promoted the efficient production MMP through a free-radical pathway. Other lignin derivatives with different functional groups were also efficiently converted to the corresponding products over the prepared catalyst. This work may provide a new idea for designing a biomass-derived catalyst for efficient transformation of various lignin derivatives to produce value-added biofuels and chems.

On account of that, the S-scheme structure effectively separated the photogenerated electron-hole pairs and enhanced the photoredox ability of the photocatalytic system. The α-Fe₂O₃/Cu₂O composite could also enhance the reactivity to a large extent. This work will provide new insight into the design of photocatalysts with a more reasonable structure and higher performance.
