GTBP Inhibitors

GTBP inhibitors belong to a unique chemical class within the realm of molecular compounds that have garnered significant attention in recent years. These compounds are characterized by their ability to interact with and modulate the activity of GTBP, which stands for "G-quadruplex binding protein." GTBP is a vital protein involved in the recognition and binding of G-quadruplex DNA structures. G-quadruplexes are secondary structures of DNA that form when guanine-rich regions of the DNA molecule fold into a four-stranded helical conformation, involving Hoogsteen hydrogen bonding. These structures are abundant in the human genome, particularly in regulatory regions such as promoters and telomeres.

GTBP inhibitors are designed to interfere with the interaction between GTBP and G-quadruplexes, ultimately influencing the regulation of gene expression. They achieve this by binding to GTBP or the G-quadruplex DNA, disrupting the normal functioning of this protein-DNA interaction. The unique feature of GTBP inhibitors lies in their potential to modulate various cellular processes by altering the expression of specific genes
