BMN-673(Cat No.:I000776), also known as talazoparib, is a small molecule inhibitor of the enzyme poly (ADP-ribose) polymerase (PARP). PARP is a protein involved in the DNA damage response pathway, repairing damaged DNA and preventing the accumulation of mutations. By inhibiting the activity of PARP, BMN-673 can selectively target cancer cells that have defects in DNA repair pathways, such as those with BRCA mutations. This leads to the accumulation of DNA damage and ultimately cell death. BMN-673 has been approved by the FDA for the treatment of advanced ovarian cancer and breast cancer in patients with BRCA mutations, and it is being studied in clinical trials for the treatment of other types of cancer.
