Recognition of DNA/RNA bulges by antimicrobial and antitumor metallohelices

Popis výsledku v původním jazyce

Bulged structures have been identified in nucleic acids and have been shown to be linked to biomolecular processes involved in numerous diseases. Thus, chemical agents with affinity for bulged nucleic acids are of general biological significance. Herein,the mechanism of specific recognition and stabilization of bulged DNA and RNA by helical bimetallic species was established through detailed molecular biophysics and biochemistry assays. These agents, known as 'flexicates', are potential mimetics of alpha-helical peptides in cancer treatment, exhibiting antimicrobial and antitumor effects. The flexicates have positive impacts on the thermal stability of DNA duplexes containing bulges, which means that the flexicates interact with the duplexes containing bulges, and that these interactions stabilize the secondary structures of these duplexes. Notably, the stabilising effect of the flexicates increases with the size of the bulge, the maximal stabilization is observed for the duplexes con
