pamiparib

Pamiparib (BGB-290) is an orally active, potent, highly selective PARP inhibitor with IC50 values of 0.9 nM for PARP1 and 0.5 nM for PARP2. It exhibits strong PARP trapping, has the capability to penetrate the brain, and is used for researching various cancers, including solid tumors.

Pamiparib is a highly potent and selective PARP inhibitor. BGB-290 selectively binds to PARP and prevents PARP-mediated repair of single-strand DNA breaks via the base-excision repair (BER) pathway. This enhances the accumulation of DNA strand breaks, pro

Pamiparib, also known as BGB-290, is a highly potent and selective PARP inhibitor with favorable drug metabolism and pharmacokinetic properties. BGB-290 selectively binds to PARP and prevents PARP-mediated repair of single-strand DNA breaks via the base-excision repair (BER) pathway. This enhances the accumulation of DNA strand breaks, promotes genomic instability, and eventually leads to apoptosis. BGB-290 may both potentiate the cytotoxicity of DNA-damaging agents and reverse tumor cell chemo- and radioresistance.
