Harnessing Chemical Diversity to Disarm Bacterial Communication for 25 Years: Natural Products, Repurposed Drugs, Peptides, and Synthetic Quorum Sensing Inhibitors.

Quorum sensing, a bacterial communication pathway, has emerged as a promising target for the development of alternative antimicrobial agents in the battle against bacterial resistance. In addition to biological investigations of quorum sensing mechanisms, substantial efforts have been made towards the rational design, synthesis, identification of natural products, and screening of commercial drugs towards this target. There are several individual reviews on the discovery of quorum sensing inhibitors; however, there has yet to be a comprehensive, detailed, and critical review providing a complete overview of the development of novel quorum sensing inhibitors, ranging from natural compounds, peptides, and repurposed drugs to synthetic molecules.

Long-Term Functional Correction of Pompe Disease and Increased α-Glucosidase Expression after Gene Therapy with Novel Combinations of Muscle-Targeted Transcriptional -Regulatory Elements.

The development of efficient and safe muscle-directed gene therapy is an unmet medical need. One of the bottlenecks in muscle-directed gene therapy is the high levels of muscle-targeted transcription required in these afflicted target tissues. To circumvent this problem, novel transcriptional cis-regulatory elements (CREs) were identified by transcriptome-wide data-mining that led to a significant increase of transgene expression in skeletal muscle, heart, and diaphragm after adeno-associated viral vector 9 (AAV9) gene transfer.

Solvent Etching Process for Graphitic Carbon Nitride Photocatalysts Containing Platinum Cocatalyst: Effects of Water Hydrolysis on Photocatalytic Properties and Hydrogen Evolution Behaviors.

In this study, we synthesized Pt/g-CN photocatalysts modified by a solvent etching process where ethanol (Pt/CN0), water (Pt/CN100), and a 50:50 mixture (Pt/CN50) were used as a solvent, and investigated the optimal properties of g-CN to prepare the best Pt/g-CN for photocatalytic hydrogen evolution. From diverse characterizations, water was proven to be a stronger solvent agent, resulting in not only the introduction of more O-functional groups onto the g-CN surface, but also the degradation of a regular array of tri-s-triazine units in the g-CN structure. While the addition of O-functional groups positively influenced the oxidation state of the Pt cocatalyst and the hydrogen production rate, the changes to g-CN structure retarded charge transfer on its surface, inducing negative effects such as fast recombination and less oxidized Pt species.

In this study, ethanol is used as a solvothermal solvent to modify the surface properties of g-CN for the first time.

Gene therapy for hemophilia B using CB 2679d-GT: a novel factor IX variant with higher potency than factor IX Padua.

Sustained expression of therapeutic factor IX (FIX) levels has been achieved after adeno-associated viral (AAV) vector-based gene therapy in patients with hemophilia B. Nevertheless, patients are still at risk of vector dose-limiting toxicity, particularly liver inflammation, justifying the need for more efficient vectors and a lower dosing regimen. A novel increased potency FIX (designated as CB 2679d-GT), containing 3 amino acid substitutions (R318Y, R338E, T343R), significantly outperformed the R338L-Padua variant after gene therapy.
