The latest developments of bifunctional oxygen electrocatalysts for Zn–air batteries (ZABs) are comprehensively summarized and evaluated, laying special emphasis on the challenges, outlooks directions future research ZAB industry.
Rationale: Breast cancer preferentially develops osteolytic bone metastasis, which makes patients suffer from pain, fractures and spinal cord compression. Accumulating evidences have shown that exosomes play an irreplaceable role in pre-metastatic niche formation as a communication messenger. However, the function of secreted by breast cells remains incompletely understood metastasis cancer. Methods: Mouse xenograft models intravenous injection were applied for analyzing cell-derived vivo....
Triple negative breast cancer (TNBC) continues to be the most aggressive subtype of that frequently develops resistance chemotherapy. Doxorubicin (DOX) belongs anthracycline chemical class drug and is one widely used anticancer drugs. This study investigates mechanism m6A methyltransferase ZC3H13 in DOX TNBC. ZC3H13, KCNQ1OT1, TRABD expressions TNBC tissues or cells were detected by RT-qPCR Western blot. The effect on was evaluated CCK-8, clone formation, EdU staining. RIP performed analyze...
Abstract An efficient metal‐free oxidative esterification of benzyl CH bonds was developed. Using tetrabutylammonium iodide as catalyst and tert ‐butyl hydroperoxide co‐oxidant, benzylic substrates could react smoothly with various carboxylic acids to give the esters good excellent yields. The method also suitable for O ‐protection N ‐Boc amino acids. reaction mechanism primarily investigated a radical process proposed.
Abstract A photoredox‐catalyzed three‐component synthesis of N ‐aminosulfonamides starting from diaryliodonium salts, hydrazines and sulfur dioxide is reported. This reaction proceeds under mild conditions at room temperature driven by visible light. simple bisulfite salt can be used as a readily available easy‐to‐handle source. Mechanistic studies support catalytic photoredox pathway with the convenient source for aryl radicals. magnified image
Abstract A copper‐catalyzed, cross‐dehydrogenative coupling of anilines with sodium and lithium sulfinates was developed. By using a cooperative reaction system Mn(OAc) 3 as stoichiometric co‐oxidant highly selective para ‐functionalization accomplished. Various functional groups were tolerated the desired products obtained in high yields. This method not only provides novel approach for synthesis arylsulfones but might also offer new opportunities development copper‐catalyzed ‐selective C−H...
Sulfinate salts have attracted considerable attentions due to their versatile reactivity. They emerged as highly useful building blocks for the construction of all kinds sulfonyl‐group containing molecules, such sulfones or sulfonamides, and various carbon–carbon‐ carbon–heteroatom‐bonds via sulfur dioxide (SO 2 ) extrusion. Herein, we want summarize latest developments in synthesis sulfinate salts. Both improvement classical methods development novel protocols will be discussed. Also...
Introduction: Ulcerative colitis (UC) is an inflammatory bowel disease with a high incidence rate and difficult treatment regimen. Recently, significant advances in the of intestinal diseases, particularly UC, have been made use drugs baicalin baicalein, separately or combination. However, therapeutic efficacy mechanism action baicalin, their combination therapy, UC has not fully elucidated. Materials Methods: we constructed rat model that encompassed variety complex factors, including...
Abstract A simple and mild copper‐catalyzed sulfonylation of 8‐aminoquinolines with sodium lithium sulfinates is reported.

The brushless doubly-fed wind power system based on conventional control strategies lacks 'inertia' and the ability to support grid, which leads decline of grid stability. Therefore, a strategy reluctance generator (BDFRG) virtual synchronous (VSG) is proposed solve problem in this paper. output characteristics BDFRG VSG are similar (SG), can frequency increase 'inertia'. According mathematical model BDFRG, inner loop voltage source derived. In addition, specific structure parameter...
