ProTides for Antiviral Activity Beyond Liver Cells

Chemistry – A European Journal, EarlyView.
A strategy for obtaining prodrugs of antiviral nucleotides with broad tissue activity is presented that relies on cycloalkyl or cycloalkylalkyl esters, improving uptake and esterase cleavage, and producing nanomolar inhibitors in kidney, colon, and lung cells.

Simple Guanosine—Amino Acid Hybrids as Low Molecular Weight Hydrogelators

Chemistry – A European Journal, EarlyView.
Unexplored guanosine‐amino acid derivatives act as low molecular weight hydrogelators. Gelation is triggered by K+ ions and pH changes and relies on G‐quadruplex formation. Small changes in the amino acid structure have a strong impact on the mechanical properties of the gels.

Nucleosided derived antibiotics to fight microbial drug resistance: New utilities for an established class of drugs? [PDF]

, 2016
Novel antibiotics are urgently needed to combat the rise of infections due to drug-resistant microorganisms. Numerous natural nucleosides and their synthetically modified analogues have been reported to have moderate to good antibiotic activity against ...

Electrochemically Driven Domino Nucleophilic Addition/Diels–Alder Reaction: From 2‐Aminophenol Derivatives to Bridged Tricyclic Systems

European Journal of Organic Chemistry, EarlyView.
This electrochemical methodology allows the preparation of bridged tricyclic scaffolds through a rapid increase in the molecular complexity of simple and readily accessible starting materials. Alcohols proved to be the most efficient nucleophiles, as well as 6‐chloropurine. Plausibly, the process involves an anodic oxidative dearomatization to generate

Analysis of radiation-induced bystander effects using high content screening [PDF]

, 2008
When cells are exposed to (ionising) radiation there is a rapid phosphorylation of a minor nucleosomal histone protein, H2AX, at the sites where double stranded breaks (DSB) occur. This phosphorylation is one of the earliest events in the repair cascade

1,2‐Diazetidines − Structure, Synthesis, and Functionalization

European Journal of Organic Chemistry, EarlyView.
1,2‐Diazetidines are saturated four‐membered heterocycles featuring two adjacent nitrogen atoms. Despite recent advances in their synthesis and promising potential in medicinal chemistry, the chemistry of these cyclic hydrazines remains underexplored.
