Aryl urea substituted fatty acids: a new class of protonophoric mitochondrial uncoupler that utilises a synthetic anion transporter.

Chem Sci 2020 Aug 19;11(47):12677-12685. Epub 2020 Aug 19.

Discipline of Pharmacology, School of Medical Sciences, University of Sydney Sydney NSW 2006 Australia.

Respiring mitochondria establish a proton gradient across the mitochondrial inner membrane (MIM) that is used to generate ATP. Protein-independent mitochondrial uncouplers collapse the proton gradient and disrupt ATP production by shuttling protons back across the MIM in a protonophoric cycle. Continued cycling relies on the formation of MIM-permeable anionic species that can return to the intermembrane space after deprotonation in the mitochondrial matrix. Read More

Substrate-Independent, Regenerable Anti-Biofouling Coating for Polymeric Membranes.

Membranes (Basel) 2021 Mar 13;11(3). Epub 2021 Mar 13.

Institute for Frontier Materials, Deakin University, Geelong, VIC 3216, Australia.

Biofouling is a common but significant issue in the membrane process as it reduces permeate flux, increases energy costs, and shortens the life span of membranes. As an effective antibacterial agent, a small amount of silver nanoparticles (AgNPs) immobilized on membrane surfaces will alleviate the membrane from biofouling. However, loading AgNPs on the membrane surface remains a challenge due to the low loading efficiency or the lack of bonding stability between AgNPs and the membrane surface. Read More

Surficial N+ charge density indicating antibacterial capacity of quaternary ammonium resins in water environment.

PLoS One 2020 30;15(9):e0239941. Epub 2020 Sep 30.

State Key Laboratory of Pollution Control and Resource Reuse, School of the Environment, Nanjing University, Nanjing, China.

The antibacterial effects of quaternary ammonium resins (QARs) have been reported for decades, but there are few practical applications because of limited improvements in bactericidal capacity and the absence of an efficient antibacterial-indicating parameter. An in-situ determination method of surficial N+ groups for QARs, defined as surficial N+ charge density, was first established to merely quantify the exposed surficial quaternary ammonium groups (QAs). The mechanism of the new method depends on the tetraphenylboron sodium standard solution (TS), which is a colloidal solution with high steric hindrance, making it difficult to permeate into QARs and further react with the inner QAs.
