Yang, Peng-Fei;Zhu, Lei;Liang, Jian-Xing;Zhao, Han-Tong;Zhang, Jian-Xin;Zeng, Xian-Wang;Ouyang, Qin;Shu, Wei research published 《 Regio- and Enantioselective Hydroalkylations of Unactivated Olefins Enabled by Nickel Catalysis: Reaction Development and Mechanistic Insights》, the research content is summarized as follows. Direct construction of fully alkyl-substituted tertiary chiral centers remote to activating groups is highly challenging and desirable. Herein, a Ni-catalyzed enantioselective hydroalkylation of unactivated alkenes with unactivated alkyl halides at room temperature is reported, providing a general and practical access to fully alkyl-substituted tertiary stereogenic carbon centers not adjacent to activating groups. This reaction undergoes regio- and stereoselective hydrometalation of unactivated alkenes with a nontrivial Markovnikov selectivity, followed by cross-coupling with unactivated alkyl electrophiles to access trialkyl tertiary saturated stereogenic centers not adjacent to activating groups. The mild and robust conditions enable the use of terminal and internal unactivated alkenes and unactivated primary and secondary alkyl, benzyl and propargyl halides to construct diverse trialkyl tertiary stereogenic carbon centers with broad functional group tolerance. Moreover, exptl. investigations support the reaction undergoing irreversible and stereoselective hydrometalation of alkenes. D. functional theory calculations provide further insights into the reaction mechanism, suggesting a stereoselective migration insertion of alkenes with Ni(II)-H species. Finally, the origin of the regio- and enantioselectivities was also investigated.

Wang, Tianyu;Yang, Chen;Zhang, Shuang;Rong, Liyan;Yang, Xiaofei;Wu, Zhaoxia;Sun, Wentao research published 《 Metabolic changes and stress damage induced by ammonia exposure in juvenile Eriocheir sinensis》, the research content is summarized as follows. The application of nitrogen fertilizers in the rice-crab co-culture system may expose juvenile Eriocheir sinensis to high ammonia concentrations within a short period of time, potentially causing death. Currently, the mol. mechanism underlying ammonia toxicity in juvenile Eriocheir sinensis remains poorly understood. This study compared the effects of 24 h exposure to different total ammonia-N concentrations (0, 10.47, and 41.87 mg/L) on antioxidant enzyme activities and tandem mass tag (TMT)-based proteomics in the hepatopancreas of juvenile Eriocheir sinensis. During the experiment, water temperature and pH were maintained at 20.4 ± 1.4°C and 7.69 ± 0.46, resp. Proteomic data demonstrated that Eriocheir sinensis used different metabolic regulatory mechanisms to adapt to varying ammonia conditions. The tricarboxylic acid (TCA) cycle, glycogen degradation, and oxidative phosphorylation showed marginally upregulated trends under low ammonia exposure. High ammonia stress caused downregulation of the TCA cycle and provided energy by enhancing oxidative phosphorylation, fatty acid beta oxidation, gluconeogenesis, and glycogen degradation The detoxification of ammonia into urea and glutamine was suppressed under high ammonia stress. Finally, ammonia exposure induced oxidative stress and caused protein damage. Antioxidant enzyme activity anal. further revealed that exposure to high concentrations of ammonia may induce more severe oxidative stress. This study provides a global perspective on the mechanisms underlying ammonia exposure-induced metabolic changes and stress damage in juvenile Eriocheir sinensis.

Authors also explored the electronic and steric effects for Ph alkynes and aryl iodides including heteroaromatics like thiophene, pyridine, pyrazole, and pyrazine. Similarly, yields of 71-96% were obtained for palladium loading of 1.5 mol% through catalyzed Heck coupling of aryl iodides and alkenes.

Wang, Ying;Chen, Ji-Kai;Xiong, Ling-Xiao;Wang, Bang-Jin;Xie, Sheng-Ming;Zhang, Jun-Hui;Yuan, Li-Ming research published 《 Preparation of Novel Chiral Stationary Phases Based on the Chiral Porous Organic Cage by Thiol-ene Click Chemistry for Enantioseparation in HPLC》, the research content is summarized as follows. Porous organic cages (POCs) are an emerging class of porous materials that have aroused considerable research interest because of their unique characteristics, including good solubility and a well-defined intrinsic cavity. However, there have so far been no reports of chiral POCs as chiral stationary phases (CSPs) for enantioseparation by high-performance liquid chromatog. (HPLC). Herein, we report the first immobilization of a chiral POC, NC1-R, on thiol-functionalized silica using a mild thiol-ene click reaction to prepare novel CSPs for HPLC. Two CSPs (CSP-1 and CSP-2) with different spacers have been prepared CSP-1, with a cationic imidazolium spacer, exhibited excellent enantioselectivity for the resolution of various racemates. Twenty-three and 12 racemic compounds or chiral drugs were well enantiosepd. on the CSP-1-packed column under normal-phase and reversed-phase conditions, resp., including alcs., diols, esters, ethers, ketones, epoxides, organic acids, and amines. In contrast, chiral resolution using CSP-2 (without a cationic imidazolium spacer)-packed column B was inferior to that of column A, demonstrating the important role of the cationic imidazolium spacer for chiral separation The chiral separation capability of column A was also compared with that of two most popular com. chiral columns, Chiralpak AD-H and Chiralcel OD-H, which exhibits good chiral recognition complementarity with the two com. chiral columns. In addition, five positional isomers dinitrobenzene, nitroaniline, chloroaniline, bromoaniline, and iodoaniline were also well separated on column A. The effects of temperature, mobile phase composition, and injected analyte mass for separation on column A were investigated. Column A also showed good stability and reproducibility after repeated injections. This work demonstrates that chiral POCs are promising chiral materials for HPLC enantioseparation

Watson, Maegan J.;Park, Yeonwoo;Thoreen, Carson C. research published 《 Roadblock-qPCR simple and inexpensive strategy for targeted measurements of mRNA stability》, the research content is summarized as follows. The stability of mRNAs is fundamental to determining expression level and dynamics. Nonetheless, current approaches for measuring transcript half-lives (e.g., transcription shutoff) are generally toxic or tech. complex. Here we describe an alternative strategy for targeted measurements of endogenous mRNA stability that is simple, inexpensive, and nontoxic. Cells are first metabolically labeled with the nucleoside analog 4-thiouridine (4sU). Extracted mRNA can then be treated with the thiol-reactive compound N-ethylmaleimide. This compound modifies 4sU nucleotides and sterically interferes with reverse transcription of 4sU-containing transcripts, disrupting their conversion into cDNA. The decay rate of non-4sU-containing preexisting mRNA can then be monitored by quant. PCR (qPCR). Importantly, this approach avoids the biochem. isolation of 4sU-labeled transcripts and/or RNA-seq anal. required for other metabolic-labeling strategies. In summary, our method combines the simplicity of “transcription shutoff” strategies with the accuracy of metabolic-labeling strategies for measurements of mRNA stability across a wide range of half-lives.
