Palacaparib
PARP1 Inhibitor
Palacaparib is a potent inhibitor of PARP1, demonstrating over 8000-fold selectivity for PARP1 relative to PARP2, PARP3, PARP5a, and PARP6. It functions by selectively inhibiting PARP1 and trapping it at sites of single-strand breaks (SSBs), impeding DNA repair. This compound is investigated primarily for its anti-cancer properties, particularly in research related to HRD+ breast cancer and various advanced solid tumors.
