TMSN Initiated Electrochemical Mono-Dealkylation of Tertiary Amides.

-Dealkylation of amides is a general process in living organisms and organic synthetic chemistry, but an efficient chemical approach for this transformation has not been explored. Herein, we report an electrochemical method for the monodealkylation of a wide range of tertiary amides, including benzamides, alkyl amides, lactams, and sulfonamides. The reaction proceeds smoothly under mild conditions using TMSN as the initiator and is not limited to deethylation or demethylation.

A simple and efficient method for selective recovery of copper from nitric acid leaching solution of printed circuit boards containing nickel, zinc, lead, aluminum, and iron.

The Cu content in discarded printed circuit boards (PCBs) is a crucial aspect, and employing suitable methods for the recovery of Cu holds significance in resource recovery. However, the selective recovery of Cu from an acidic leaching solution containing multiple metals such as Ni, Zn, and Pb poses challenges. L-cys contains the thiol (-SH), the amino (-NH) and the carboxyl (-COOH) groups, which may complex with metal ions.

Epinephelus coioides NLRP3 inhibits SGIV infection by upregulating Capspase-1 activity.

NLRP3 has an important role in the immune response and viral infection as an essential inflammasome component. However, it is unclear whether the grouper immune system is regulated by NLRP3 inflammasome. In this study, we cloned the NLRP3 gene from Epinephelus coioides.

In vitro antiviral activity of eugenol on Singapore grouper iridovirus.

The high mortality rate of Singapore grouper iridovirus (SGIV) posing a serious threat to the grouper aquaculture industry and causing significant economic losses. Therefore, finding effective drugs against SGIV is of great significance. Eugenol (CHO) is a phenolic aromatic compound, has been widely studied for its anti-inflammatory, antioxidant and antiviral capacity.

Berberine inhibits SGIV replication by suppressing inflammatory response and oxidative stress.

Singapore grouper iridovirus (SGIV) is one of the major infectious diseases responsible for high mortality and huge economic losses in the grouper aquaculture industry. Berberine (BBR), a naturally occurring plant alkaloid, is a phytochemical having a variety of biological properties, such as antiviral, antioxidant, and anti-inflammatory effects. In this work, we used an in vitro model based on Western blot, ROS fluorescence probe, and real-time quantitative PCR (qRT-PCR) to examine the antiviral qualities of BBR against SGIV.

Development and immune evaluation of LAMP1 chimeric DNA vaccine against Singapore grouper iridovirus in orange-spotted grouper, Epinephelus coioides.

Grouper is one of the most important and valuable mariculture fish in China, with a high economic value. As the production of grouper has increased, massive outbreaks of epidemic diseases have limited the development of the industry. Singapore grouper iridovirus (SGIV) is one of the most serious infectious viral pathogens and has caused huge economic losses to grouper farming worldwide due to its rapid spread and high lethality.

Curcumin Alleviates Singapore Grouper Iridovirus-Induced Intestine Injury in Orange-Spotted Grouper ().

Singapore grouper iridovirus (SGIV) is a new ranavirus species in the Iridoviridae family, whose high lethality and rapid spread have resulted in enormous economic losses for the aquaculture industry. Curcumin, a polyphenolic compound, has been proven to possess multiple biological activities, including antibacterial, antioxidant, and antiviral properties. This study was conducted to determine whether curcumin protected orange-spotted grouper () from SGIV-induced intestinal damage by affecting the inflammatory response, cell apoptosis, oxidative stress, and intestinal microbiota.

Design and evaluation of dibenzoazepine-tetrahydroisoquinoline hybrids as potential P-glycoprotein inhibitors against multidrug resistant K562/A02 cells.

Multidrug resistance (MDR) caused by P-glycoprotein (P-gp) is a main barrier to the success of cancer chemotherapies. In this study, fourteen novel dibenzoazepine-tetrahydroisoquinoline hybrids were prepared as potential P-gp inhibitors to surmount MDR caused by P-gp. Amongst them, 8a displayed the most potent inhibition effect on P-gp, thus effectively reversing P-gp-mediated drug resistance with a reversal fold (RF) value of 93.

Functional analysis of the Cystatin F gene response to SGIV infection in orange-spotted grouper, Epinephelus coioides.

Cystatin F (CyF), an inhibitor of cysteine protease, was widely studied in immune defense and cancer therapy. However, the function of CyF and its latent molecular mechanism during virus infection in fish remain vacant. In our research, we cloned the open reading frame (ORF) of CyF homology from orange-spotted grouper (Ec-CyF) consisting of 342 nucleotides and encoding a 114-amino acid protein.

Functional Analysis of the Cathepsin D Gene Response to SGIV Infection in the Orange-Spotted Grouper, .

(1) Background: Lysosomal aspartic protease Cathepsin D (CD) is a key regulator and signaling molecule in various biological processes including activation and degradation of intracellular proteins, the antigen process and programmed cell death. However, the function of fish CD in virus infection remains largely unknown. (2) Methods: The functions of the CD gene response to SGIV infection was determined with light microscopy, reverse transcription quantitative PCR, Western blot and flow cytometry.

Functional analysis of the cystatin A gene response to SGIV infection in orange-spotted grouper, Epinephelus coioides.

Cystatin A (CyA), an inhibitor of cysteine protease, was widely studied in immune defense and cancer therapy. However, the function of CyA and its potential molecular mechanism during virus infection in fish remain unknown. In our study, we cloned the open reading frame (ORF) of CyA homology from orange-spotted grouper (Ec-CyA) consisting of 303 nucleotides and encoding a 101-amino acid protein.
