Antibiotics Research and Re-evaluation Key Laboratory of Sichuan Province, Sichuan Industrial Institute of Antibiotics, School of Pharmacy, Chengdu University, 2025 Chengluo Avenue, Chengdu 610016, P. R. China.

We report a highly regioselective 1,2-addition of P(O)-H compounds to the in situ generated β,γ-alkynyl-α-ketimine derived from 3-alkynyl-3-hydroxyisoindolinones, which provided a general protocol for the preparation of 3,3-disubstituted isoindolinones featuring both phosphoryl and alkynyl groups at a quaternary carbon center. The use of only 2-5 mol % of an inexpensive catalyst (In(ClO)·8HO or Bi(OTf)) allowed the smooth output of the desired products under mild conditions (25 °C, 0.5-24 h) with a broad substrate scope (35 examples) in up to >99% yield.

Osteoarthritis (OA) presents a significant therapeutic challenge, with few options for preserving joint cartilage and repairing associated tissue damage. Inflammation is a pivotal factor in OA-induced cartilage deterioration and synovial inflammation. Recently, exosomes derived from human umbilical cord mesenchymal stem cells (HucMSCs) have gained recognition as a promising noncellular therapeutic modality, but their use is hindered by the challenge of harvesting a sufficient number of exosomes with effective therapeutic efficacy.

Key Laboratory of Drug-Targeting and Drug Delivery System of the Education Ministry and Sichuan Province, Sichuan Engineering Laboratory for Plant-Sourced Drug and Sichuan Research Center for Drug Precision Industrial Technology, West China School of Pharmacy, Sichuan University, Chengdu 610041, China.. Electronic address:

Sepsis is a life-threatening disease characterized by excessive systemic inflammation and coagulopathy. Platelets and neutrophils form a "dangerous alliance" through crosstalk, promoting the inflammatory cytokine storm and coagulation disorders during sepsis. Platelet-neutrophil crosstalk leads to the formation of platelet-neutrophil complexes (PNCs), which are the central "protagonists" of this "dangerous alliance.

Shanghai Engineering Research Center of Food Microbiology, School of Health Science and Engineering, University of Shanghai for Science and Technology, Shanghai 200093, China. Electronic address:

Promoters are crucial elements for controlling gene expression in cells, yet lactic acid bacteria (LAB) often lack a diverse set of available constitutive promoters with quantitative characterization. To enrich the LAB promoter library, this study focused on the known strong constitutive promoter P in LAB. Through error-prone PCR and dNTP analog-induced random mutagenesis, a library of 247 mutants of P was generated by using the red fluorescent protein (RFP) fluorescence intensity as a high-throughput screening indicator in Streptococcus thermophilus.

Background: A recent study conducted by the laboratory of the first author revealed that major depression is composed of two distinct subtypes: major dysmood disorder (MDMD) and simple dysmood disorder (SDMD). The latter is a less severe phenotype with fewer aberrant biological pathways. MDMD, but not SDMD, patients were identified to have highly sensitized cytokine/growth factor networks using stimulated whole blood cultures.

College of Environmental Science, Sichuan Agricultural University, Chengdu, Sichuan, 611130, PR China; Sichuan Provincial Engineering Research Center of Agricultural Non-point Source Pollution Control, Sichuan Agricultural University, Chengdu, Sichuan, 611130, PR China.

As a newly developed technology, lignocellulose pretreatment of PHP (phosphoric acid coupled with hydrogen peroxide) can facilitate the enzymatic hydrolysis of pretreated lignocellulose for glucose production. It also has been found that the derived oxidative tail gas from pretreatment can facilely degrade organic pollutant. To balance the pollutant degradation and the glucose yield, the collaborative optimization on pretreatment was investigated.

This study investigated the interactions between Capsaicinoids (CAPs) and beef myofibrillar proteins (MPs) in a peroxyl radical system and elucidated the antioxidant mechanisms of CAPs by multispectral and molecular docking. Results showed that low concentration CAPs prevented the oxidative changes of protein structure caused by the attack of AAPH radicals on MPs, while high concentration of CAPs changed the structure of the proteins to form more small molecule aggregates, and reduce the binding of actin-myosin, which was conducive to the tenderization of the meats. CAPs bound to the MPs through hydrophobic interaction, hydrogen bonding and electrostatic interaction, altering the secondary and tertiary structure of MPs, increasing the α-helix content of MPs, and improving the antioxidant structural stability of MPs.
