BRCA1-IN-1 is primarily utilized in research settings to study the role of BRCA1 in cellular processes, particularly in DNA repair mechanisms. It serves as a tool compound to inhibit BRCA1 activity, allowing scientists to investigate the consequences of BRCA1 dysfunction in cancer development and progression. This chemical is especially valuable in understanding the molecular pathways involved in hereditary breast and ovarian cancers, where BRCA1 mutations are commonly implicated. Additionally, BRCA1-IN-1 aids in exploring potential therapeutic strategies targeting BRCA1-deficient cancers, contributing to the development of novel treatments for patients with these genetic predispositions.
