Abstract:

DNA or RNA guanine-rich sequences can form non-canonical secondary structures known as G-quadruplexes. The structures of G-quadruplex are rich and diverse, and they exist dynamically in organisms. G-quadruplex is involved in key genomic functions such as transcription, replication, genomic stability and epigenetic regulation and is closely related to cancer biology. The studies on the structural and functional mechanisms of G-quadruplex have promoted G-quadruplex-targeted tumor intervention and treatment. This paper reviews the specific recognition, cell detection and biological functional regulation of G-quadruplex, summarizes the research progress in designing small molecules recognizing and targeting of G-quadruplex and their complex structures. The possibility of G-quadruplex-targeted intervention and disease treatment is discussed. Finally, the challenges and opportunities in the future research of G-quadruplex field are prospected.

Key words: G-quadruplex, Specific recognition, Intracellular detection, Complex structure, Functional regulation
