Wang, Juan;Liang, Boqiang;Chen, Yiling;Fuk-Woo Chan, Jasper;Yuan, Shuofeng;Ye, Hui;Nie, Linlin;Zhou, Jiao;Wu, Yi;Wu, Meixian;Huang, Lina S.;An, Jing;Warshel, Arieh;Yuen, Kwok-Yung;Ciechanover, Aaron;Huang, Ziwei;Xu, Yan research published 《 A new class of α-ketoamide derivatives with potent anticancer and anti-SARS-CoV-2 activities》, the research content is summarized as follows. Inhibitors of the proteasome have been extensively studied for their applications in the treatment of human diseases such as hematol. malignancies, autoimmune disorders, and viral infections. Many of the proteasome inhibitors reported in the literature target the non-primed site of proteasome′s substrate binding pocket. In this study, we designed, synthesized and characterized a series of novel α-keto phenylamide derivatives aimed at both the primed and non-primed sites of the proteasome. In these derivatives, different substituted Ph groups at the head group targeting the primed site were incorporated in order to investigate their structure-activity relationship and optimize the potency of α-keto phenylamides. In addition, the biol. effects of modifications at the cap moiety, P1, P2 and P3 side chain positions were explored. Many derivatives displayed highly potent biol. activities in proteasome inhibition and anticancer activity against a panel of six cancer cell lines, which were further rationalized by mol. modeling analyses. Furthermore, a representative α-ketoamide derivative was tested and found to be active in inhibiting the cellular infection of SARS-CoV-2 which causes the COVID-19 pandemic. These results demonstrate that this new class of α-ketoamide derivatives are potent anticancer agents and provide exptl. evidence of the anti-SARS-CoV-2 effect by one of them, thus suggesting a possible new lead to develop antiviral therapeutics for COVID-19.

Dispersity (D) of polymers has a great effect on the properties of polymeric materials, and therefore how to control D is very important but still a huge challenge in polymer synthesis, especially for reversible-deactivation radical polymerization (RDRP) strategy. Herein, we successfully developed a novel strategy to adjust D of polymers by visible light-controlled reversible complexation mediated living radical polymerization (RCMP) and combination of single-electron transfer-degenerative chain transfer living radical polymerization (SET-DTLRP) at room temperature In RCMP system, 2-iodo-2-methylpropionitrile (CP-I) and Et 2-iodo-2-phenylacetate (EIPA) were used as alkyl iodide initiators, by using Me methacrylate (MMA) as the model monomer and n-butylacrylate (BA) as the end-capping reagent to regulate D of polymers. Subsequently, we successfully prepared the block copolymer PMMA-b-PBA with adjustable D by reactivating the polymer end-chains via SET-DTLRP in the presence of copper wire, fully demonstrating that it is a promising strategy that can keep the “living” feature of polymers while regulating their molar mass dispersities easily.

Furfural (2-furaldehyde) is a promising platform chem. for lignocellulosic biofuels, but its thermal decomposition channels are not well understood. To better understand furfural thermal decomposition kinetics, flow tube reactor pyrolysis combined with synchrotron vacuum UV photoionization mass spectrometry at low and atm. pressures and temperatures from 929 to 1365 K was investigated. Carbon monoxide, methane, acetylene, propyne, allene, furan, and vinylketene as the main products were detected and measured. A detailed kinetic model for furfural pyrolysis consisting of 585 species and 3018 reactions was built based on the potential energy surface, and validated against the exptl. data from the current and previous studies. Rate of production anal. shows that furfural mainly underwent unimol. non-radical decomposition channel to form vinylketene and carbon monoxide. Sequential decomposition of vinylketene led to the production of allene, propyne and carbon monoxide, etc. H-atom addition reactions on the furan ring was the main source of furan. HCO, CH3 and COOCH3 groups influence the decomposition pathways of furanic fuels, and accelerate their decomposition with decomposition temperatures in the sequence of Me 2-furoate < furfural < 2,5-dimethylfuran < 2-methylfuran < furan.

The ability to reverse controlled radical polymerization and regenerate the monomer would be highly beneficial for both fundamental research and applications, yet this has remained very challenging to achieve. Herein, we report a near-quant. (up to 92%) and catalyst-free depolymerization of various linear, bulky, crosslinked, and functional polymethacrylates made by reversible addition-fragmentation chain-transfer (RAFT) polymerization Key to our approach is to exploit the high end-group fidelity of RAFT polymers to generate chain-end radicals at 120°C. These radicals trigger a rapid unzipping of both conventional (e.g., poly(Me methacrylate)) and bulky (e.g., poly(oligo(ethylene glycol) Me ether methacrylate)) polymers. Importantly, the depolymerization product can be utilized to either reconstruct the linear polymer or create an entirely new insoluble gel that can also be subjected to depolymerization This work expands the potential of polymers made by controlled radical polymerization, pushes the boundaries of depolymerization, offers intriguing mechanistic aspects, and enables new applications.

This study aimed to assess the effects of Penicillium expansum (P. expansum) infection on the quality and flavor of Jinmi (JM) and Jinyan (JY) kiwifruit. Kiwifruit were inoculated with P. expansum and stored at 0 ± 1°C, and the changes in quality indicators and volatile substances (VCs) at different stages of disease were determined In wound-inoculated kiwifruit, the soluble solid content (SSC) increased. Conversely, their titratable acidity and vitamin C (VC) content, firmness, lightness, and saturation decreased. The taste-related parameters and nutritional value of kiwifruit declined after infection. VCs such as ethanol, 3-methyl-1-butanol, and 2-methylisoborneol were detected only in the diseased fruit and gradually increased as the disease aggravated, suggesting that they may be the main sources of odor during P. expansum infection. Therefore, VCs detection can be used to determine possible P. expansum infection, as well as the degree of infection in kiwifruit. Practical applications : In practical application, we can use the results of this study to determine possible Penicillium expansum infection, as well as the degree of infection in kiwifruit according to the indicators such as volatile substances. Kiwifruit enterprises can use the nondestructive detection model established in this study to screen out the kiwifruit infected with P. expansum more efficiently, quickly, and accurately, in order to prevent harm to the health of consumers.

GPR52 is an orphan G protein-coupled receptor (GPCR) that has been recently implicated as a potential drug target of Huntington’s disease (HD), an incurable monogenic neurodegenerative disorder. In this research, we found that striatal knockdown of GPR52 reduces mHTT levels in adult HdhQ140 mice, validating GPR52 as an HD target. In addition, we discovered a highly potent and specific GPR52 antagonist Comp-43 with an IC₅₀ value of 0.63μM by a structure-activity relationship (SAR) study. Further studies showed that Comp-43 reduces mHTT levels by targeting GPR52 and promotes survival of mouse primary striatal neurons. Moreover, in vivo study showed that Comp-43 not only reduces mHTT levels but also rescues HD-related phenotypes in HdhQ140 mice. Taken together, our study confirms that inhibition of GPR52 is a promising strategy for HD therapy, and the GPR52 antagonist Comp-43 might serve as a lead compound for further investigation.

Wang, Chen-Gang;Chong, Amerlyn Ming Liing;Goto, Atsushi research published 《 One Reagent with Two Functions: Simultaneous Living Radical Polymerization and Chain-End Substitution for Tailoring Polymer Dispersity》, the research content is summarized as follows. The mol. weight distribution of polymer, termed dispersity (D), is a fundamental parameter that determines polymer properties. Sodium azide (NaN₃) functions as a catalyst in organocatalyzed living radical polymerization when the reaction medium is nonpolar. In contrast, NaN₃ can act as a nucleophile when the reaction medium is polar. In this paper, we report an efficient approach to dispersity control by exploiting the dual functions of NaN₃ under the varied solvent polarity. Simultaneous polymerization and chain-end substitution allowed us to tune the D values of various polymethacrylates and poly(Bu acrylate). Notably, the D value could be tuned to a wide range approx. from 1.2 to 2.0 for polymethacrylates and to 3.8 for poly(Bu acrylate). This approach afforded polymer brushes on surfaces with tailored D values. An interesting finding was that the polymer brushes exhibited a unique interaction with external mols., depending on the D value.
