| In Vitro | BRCTs are phosphoserine-binding domains found in proteins involved in DNA repair, DNA damage response and cell cycle regulation. BRCA1 is a BRCT domain-containing, tumor-suppressing protein expressed in the cells of breast and other tissues. By targeting the (BRCT)2 domain, BRCA1-IN-1 (Compound 15a) inhibits BRCA1 activities in tumor cells, sensitizes these cells to ionizing radiation-induced apoptosis, and shows synergistic inhibitory effect when used in combination with Olaparib (a small-molecule inhibitor of poly-ADP-ribose polymerase) and Etoposide (a small-molecule inhibitor of topoisomerase II). BRCA1-IN-1 can effectively inhibit HR activity by binding to BRCA1(BRCT)2, and functionally mimic genetic knockdown of BRCA1. BRCA1-IN-1 is useful in targeting BRCA1/PARP-related pathways involved in DNA damage and repair response, for cancer therapy. The synergistic inhibition of PARP/BRCA1 (a process referred to as synthetic lethality), is highly effective in cancer therapy. BRCA1-IN-1 is small-molecule-like and can be directly administered to tumor cells, thus making them useful for future studies of BRCA1/PARP-related pathways in DNA damage and repair response, and in cancer therapy[1]. |
