SCR7 Pyrazine is primarily utilized in the field of molecular biology and genetic research. It functions as a DNA ligase inhibitor, specifically targeting the enzyme DNA ligase IV, which plays a crucial role in the non-homologous end joining (NHEJ) pathway of DNA repair. By inhibiting this enzyme, SCR7 Pyrazine is employed to study the mechanisms of DNA repair and to enhance the efficiency of gene editing techniques such as CRISPR-Cas9. This chemical is particularly valuable in research aimed at understanding how cells repair double-strand breaks and in developing strategies to improve the precision of genome editing. Additionally, SCR7 Pyrazine is used in cancer research to explore its potential in sensitizing cancer cells to radiation and chemotherapy by impairing their DNA repair capabilities. Its application extends to the development of therapeutic approaches that target DNA repair pathways in various diseases.
