Braco-19 trihydrochloride is primarily used in research focused on targeting and stabilizing G-quadruplex structures within DNA and RNA. These structures are found in key regions of the genome, such as telomeres and oncogene promoters, making them a potential target for cancer therapy. By binding to G-quadruplexes, Braco-19 trihydrochloride can interfere with the replication and transcription processes in cancer cells, potentially inhibiting their growth and proliferation. This compound is also studied for its role in telomere maintenance, as it can disrupt telomerase activity, which is often upregulated in cancer cells. Additionally, it serves as a valuable tool in biochemical and biophysical studies to understand the role of G-quadruplexes in gene regulation and cellular processes. Its application extends to exploring novel therapeutic strategies for diseases linked to G-quadruplex dysfunction, including certain cancers and genetic disorders.
