Cyclopropenium cations are aromatic three-membered rings and belong to Hückel type aromatic systems. Thus, they are the smaller brothers of the well-known benzene. In contrast to benzene cyclopropenium cations were considered for a long time as curiosities without any practical relevance. However, in recent years their potential as organocatalysts has been recognized. Furthermore, polyelectrolytes carrying aminocyclopropenium subunits have been demonstrated as promising battery materials. However, there was a missing link, i.e. low molecular aminocyclopropenium-based compounds connecting features of organocatalysts and polyelectrolytes.   

Recently, an international team from the University of Stuttgart, the Columbia University in New York, the Cornell University in Ittaca and the Colorado State University in Fort Collins successfully realized the synthesis and characterization of liquid crystalline aminocyclopropenium salts. These deltic ionic liquid crystals possess a cationic head group and long hydrophobic side chains. These aminocyclopropenium salts self-assemble due to the nano-segregation of immiscible molecular parts of different polarity into columnar or lamellar structures, so-called mesophases. These mesophases can be characterized via polarizing optical microscopy, differential scanning calorimetry and X-ray diffraction thermally and structurally and serve as models for the above mentioned polyelectrolytes. The results are reported in a VIP research article in the journal Angewandte Chemie International Edition (doi.org/10.1002/anie.202000824).

Targeted DNA methylation is a promising approach for the modulation of gene expression in basic research and in the clinic. However, it often suffers from a lack of specificity, because off-target regions also are methylated. We have rationally designed different DNMT3A variants with reduced DNA binding and applied them for targeted methylation. Our data show that this leads to a pronounced improvement in the specificity of targeted DNA methylation as indicated by a strongly reduced off-target methylation accompanied by an only mild reduction of on-target activity. These improved DNMT3A variants will advance the future applications of this emerging technology.
