Novel therapies are required due to the rising cancer burden. Conventional chemotherapeutics tend to be particularly toxic, but there is a promising alternative for oncogenes, such as c-MYC. Often overexpressed in many cancer types, the potential c-MYC oncogene seems essential to the development of cancer. Targeting c-MYC protein directly was limited, but these DNA structures composed of guanine-rich sequences suppress c-MYC transcription. This review discusses recent advances in developing small compounds that selectively bind to and stabilize c-MYC G-quadruplexes (G4). These molecules have also shown promise for the inhibition of c-MYC signaling and inhibition of tumor growth, suggesting that G-quadruplex targeting could be a promising therapeutic for cancer.

The G-quartet-like supramolecular assembly present in guanosine hydrogel templates macrocyclization between bis-azide and bis-alkyne fragments. The resulting macrocycle enhances viscoelastic properties, and strengthens the hydrogel network. This approach holds potential for the in situ synthesis of drugs and their simultaneous delivery in a stimuli-responsive manner.
