In this review article, we discuss the synthesis and dynamic nature of macromolecular systems that have mechanically linked polymer chains capable of undergoing a topology transformation driven by a ...

Commonly used by chemists as ligands for catalysts, cyclic imino ethers can also be polymerized to make materials that could help transport drugs into cells. Bart Verbraeken had been trying, ...

Researchers say they can now produce a vast library of unique cyclic compounds, some with the capacity to interrupt specific protein-protein interactions that play a role in disease. The new compounds ...

Peptide pheromone cell–cell signaling (quorum sensing) regulates the expression of diverse developmental phenotypes (including virulence) in Firmicutes, which includes common human pathogens, e.g., ...

Penicillin-based antibiotics contain a five-membered hydrocarbon cycle, additionally incorporating a sulfur and a nitrogen atom. Nadine Zumbrägel, doctoral student at the Chair of Organic Chemistry I ...

Simple toral rank 1 Lie algebras have been classified in Wilson [8]. This paper is concerned with the structure of a nonsimple toral rank 1 Lie algebra with respect to a specified "toral rank 1" ...

Cyclobutanone, a cyclic ketone, undergoes aldol self-condensation to form an α,β-unsaturated ketone, commonly known as an enone. This reaction is a classic example of how carbonyl compounds can react ...

Bacteria possess an array of defenses against foreign invaders, including a broadly distributed bacteriophage defense system termed CBASS (cyclic oligonucleotide-based anti-phage signaling system). In ...

Biologists have discovered means for speeding the transport of the active ingredients of drugs into live cells that might allow drastically reducing drug dosages in the future. Biologists at the ...
