Kwong, Ada J.;Pham, Thao N. D.;Oelschlager, Hannah E.;Munshi, Hidayatullah G.;Scheidt, Karl A. research published 《 Rational Design, Optimization, and Biological Evaluation of Novel MEK4 Inhibitors against Pancreatic Adenocarcinoma》, the research content is summarized as follows. Growth, division, and development of healthy cells relies on efficient response to environmental survival cues. The conserved mitogen-activated protein kinase (MAPK) family of pathways interface extracellular stimuli to intracellular processes for this purpose. Within these pathways, the MEK family has been identified as a target of interest due to its clin. relevance. Particularly, MEK4 has drawn recent attention for its indications in pancreatic and prostate cancers. Here, we report two potent MEK4 inhibitors demonstrating significant reduction of phospho-JNK and antiproliferative properties against pancreatic cancer cell lines. Furthermore, mol. inhibition of MEK4 pathway activates the MEK1/2 pathway, with the combination of MEK1/2 and MEK4 inhibitors demonstrating synergistic effects against pancreatic cancer cells. Our inhibitors provided insight into the crosstalk between MAPK pathways and new tools for elucidating the roles of MEK4 in disease states, findings which will pave the way for better understanding of the MAPK pathways and development of addnl. probes.

Kumru, Baris;Giusto, Paolo;Antonietti, Markus research published 《 Carbon nitride-coated transparent glass vials as photoinitiators for radical polymerization》, the research content is summarized as follows. Benign polymerization routes offer new perspectives in current polymer technol. Especially for automated or continuous flow synthesis of polymers, new devices and principles have to be considered by the means of minimizing addition or separation sequences as well as the type of a polymer initiation. Near-UV and visible light-induced polymerization utilizing metal-free semiconductor polymeric carbon nitride (pCN) as heterogeneous photocatalyst was a first step into this direction. Moving from heterogeneous powder catalysis (which still requests catalyst separation) to surface photocatalysis via coating glass tubes or vials with pCN thin films is presented. Performance and effectivity of those photoactive reactors are proven by free radical photopolymerization of variety of monomers. Reusability of vials is demonstrated via reversible addition-fragmentation chain-transfer polymerization-assisted block copolymer synthesis. This strategy eliminates the necessity of adding or removing initiators, works at room temperature, and offers a platform for cheap and effective polymer synthesis at the age of automated synthesis.

This study aims to develop an antibacterial agent that can be used for food packaging. Essential oils of Houttuynia cordata Thunb., a well-known medical herb, were extracted by two methods: multi-solvent consecutive extraction method and single ethanol extraction with a pre-heating method. Consequently, the extract obtained by the single ethanol extraction with a pre-heating method was more satisfactory from the operational and economic aspects. Afterwards, one of the encapsulation techniques: co-precipitation method using β-cyclodextrins as wall materials, was applied to form capsules for the protection of the obtained extract After the capsule synthesis, the results of scanning electron micrographs and X-ray diffraction showed β-cyclodextrin crystallites in the form of thinner plates became oriented upon co-precipitation Combining the results of Fourier transform-IR spectra and an antibacterial assay using Bacillus subtilis as an object microorganism, the extract was confirmed to be successfully encapsulated within hollow cavities of β-cyclodextrins. A significant inhibitory activity on the growth and breeding of Bacillus subtilis was observed after the addition of fabricated capsules, which suggests the capsules containing the Houttuynia cordata Thunb. extract can be used as eco-friendly antibacterial agents for food packaging.

Kitanosono, Taku;Lu, Fangqiu;Masuda, Koichiro;Yamashita, Yasuhiro;Kobayashi, Shu research published 《 Efficient Recycling of Catalyst-Solvent Couples from Lewis Acid-Catalyzed Asymmetric Reactions in Water》, the research content is summarized as follows. Bioinspired supramol. architectures were used to compartmentalize highly charged aqua scandium ions into chiral hydrophobic scaffolds for Lewis acid-catalyzed asym. reactions. Recycling without significant loss in catalytic performance was a formidable task, especially for Lewis acid-catalyzed reactions. This was because Lewis basic impurities derived from starting materials, products and water were highly competitive ligands for both substrate binding and metal complexation, thus poisoning the Lewis acids and leading to their leaching. Even when basic aniline was used, the architecture allowed for effective suppression of Sc³⁺ leaching and for reuse of solvent-catalyst couples in asym. ring-opening reactions without deactivation. Application to asym. thia-Michael addition and hydroxymethylation was also demonstrated. The successful recycling in highly Lewis basic environments underpins the exceptionally high robustness of the chiral Lewis acid catalyst.

Kim, Siyeon;Ahn, Jung Oh;Kim, Kyung-Min;Lee, Chang-Ha research published 《 Effects of the mobile phase on the chromatographic separation of L-lysine and 5-aminovaleric acid》, the research content is summarized as follows. 5-Aminovaleric acid (5AVA), an attractive bio-based carbon-5 building block for polymer synthesis, is produced from L-lysine. However, their structural similarity makes separating 5AVA from L-lysine challenging. The simulated moving bed (SMB), continuous chromatog. separation process provides a solution with high productivity and low eluent consumption. Here, the effects of the mobile phase on the separation of 5AVA and L-lysine on a C18 column are reported. Pre-column derivatization using diethylethoxymethylene malonate enhanced the detection sensitivity and separation performance, which was strongly affected by the phosphate buffer pH. A 70/30 (volume/volume) mobile phase of 20 mM phosphate buffer at pH 6.8 and acetonitrile showed the best separation performance in isocratic mode. The selectivity at adsorption equilibrium was determined from pulse experiments, and the optimal operating conditions of the SMB process were determined from the equilibrium constants of both components. The feasibility of separating 5AVA and L-lysine by the SMB process was confirmed with purity and recovery of greater than 99%. The SMB process using pre-column derivatization can provide the competitiveness of the bio-based chem. production because separation processes typically contribute to more than 70% of the total production cost.
