Abstract Research in recent decades has revealed that some DNA and RNA secondary structures modulate a variety of cellular events. One secondary structure, the Guanine(G)-quadruplex, also regulates various cellular events that are mostly related to serious diseases. Systems capable of controlling DNA and RNA G-quadruplex structures would therefore be useful for the modulation of various cellular events to produce biological effects. Because of their biological importance, many G-quadruplex-targeting compounds have been described. However, the next generation of targeting molecules should exhibit increased G-quadruplex K.
