Aminoglycosides have the potential to induce readthrough of premature termination codons, which could be valuable in treating genetic diseases. Modification of aminoglycoside compounds to reduce cellular toxicity while maintaining readthrough activity is a strategy documented in this study.
A significant proportion of genetic disease cases arise from truncation of proteins caused by premature termination codons. In eukaryotic cells some aminoglycosides cause readthrough of premature termination codons during protein translation. Inducing readthrough of these codons can potentially be of therapeutic value in the treatment of numerous genetic diseases. A significant drawback to the repeated use of aminoglycosides as treatments is the lack of balance between their readthrough efficacy and toxicity. The synthesis and biological testing of designer aminoglycoside compounds is documented herein. We disclose the implementation of a strategy to reduce cellular toxicity and maintain readthrough activity of a library of compounds by modification of the overall cationic charge of the aminoglycoside scaffold through ring I modifications.

Ytterbium (II) Hydride as a Powerful Multielectron Reductant

Georgia M. Richardson, Iskander Douair, Scott A. Cameron, Laurent Maron, Mathew D. Anker

Summary: The dimeric beta-diketiminato ytterbium(II) hydride can act as a powerful two-electron reductant at room temperature, affecting the reactions of polyaromatic hydrocarbons such as naphthalene without the need for external electron involvement.

N-acetylmannosamine-6-phosphate 2-epimerase uses a novel substrate-assisted mechanism to catalyze amino sugar epimerization

Michael J. Currie, Lavanyaa Manjunath, Christopher R. Horne, Phillip M. Rendle, Ramaswamy Subramanian, Rosmarie Friemann, Antony J. Fairbanks, Andrew C. Muscroft-Taylor, Rachel A. North, Renwick C. J. Dobson

Summary: The study found that the enzyme NanE may use a novel substrate-assisted proton displacement mechanism for catalysis, by re-evaluating the central role of Glu180 and the catalytic lysine, and identifying several active-site residues related to the mechanism. This discovery could be helpful in developing inhibitors for the enzyme or producing biocatalysts capable of changing the stereochemistry of molecules through enzyme engineering.

Summary: ddhCTP is a novel antiviral molecule that acts as a chain terminator of flavivirus and SARS-CoV-2 RNA-dependent RNA polymerases. Limited access to this promising antiviral has hindered further biophysical studies, but a robust synthesis method has been developed to prepare ddhCTP on a gram scale.

Summary: Nucleophilic alkylation of aromatics with main group reagents is limited to a stoichiometric regime. The ytterbium(II) hydride reacts with ethene and propene to form ytterbium(II) n-alkyls, which can catalyze the alkylation of benzene at room temperature through an S(N)2 mechanism.

Summary: Decoupling the roles of the farnesoid X nuclear receptor and the Takeda G-protein-coupled bile acid receptor 5 is crucial for developing novel bile acid therapeutics targeting metabolic and neurodegenerative diseases. The synthesis of 12 beta-methyl-18-nor-bile acids as probes for new bile acid analogues with clinical applicability was described, along with the mechanism insights provided by deuteration experiments. Optimization of the synthetic sequence enabled a chromatography-free route to prepare these bile acids at a multi-gram scale, highlighting the potential for future therapeutic developments.

Summary: The synthesis of analogues of natural enzyme substrates can help deduce enzymatic mechanisms, as demonstrated by the investigation into N-acetylmannosamine-6-phosphate 2-epimerase. The study suggests that this enzyme may utilize a substrate-assisted proton displacement mechanism, with two novel analogues showing different binding orientations at the enzyme's active site.

Summary: Bile acid receptors are important targets for treating metabolic and inflammatory diseases. Synthesizing new bile acid analogues helps understand their structure-activity relationships and identify selective receptor activators. In this study, a chenodeoxycholic acid derivative with specific modifications was used to explore the chemical manipulation of bile acids. Different reaction outcomes were observed when treating this derivative with different zinc carbenoid species. Further modifications and evaluations were made to these derivatives for biological purposes.
